Los Angeles Times Editorial: Residential Development Near Freeways is Bad for Health
As many people who read this blog and follow the work of USC Environmental Health Centers know, our researchers spend much of their time and energy studying the health effects of outdoor air pollution. In particular, our researchers have published many studies on how pollution near busy roads and freeways can affect people's health both in the short term and over the lifespan.
Therefore, we take particular note when media outlets such as the Los Angeles Times not only cover stories that relate to the impact of the environment on health but publish editorials about them.

Outreach program and community partners host “Diesel and Your Health” lunch forum
On November 24, the community/academic collaborative the “Trade, Health and Environment (THE) Impact Project” partners hosted the first of an ongoing lunch series. The Community Outreach and Engagement Program of USC’s Environmental Health Centers is a longstanding part of THE Impact Project. The meeting focused on the urgency of addressing health impacts from diesel emissions, and brought together organizations and concerned community members from impacted areas.
Moderator Michele Prichard, director of Common Agenda for the Liberty Hill Foundation, kicked off the program by asking participants to introduce themselves and tell the others on a scale of 1-10 how much they thought they already knew about the health effects of diesel emissions. (Attendees were much too modest in their assessments!) Presenter Andrea Hricko of USC then did a presentation on the Health Effects of Diesel, highlighting the national, state and local history of the path that diesel emission reduction has taken. She noted that although progress has been made in reducing overall diesel emissions in the Southern California regions, there is still a long way to go in terms of reducing diesel emissions in specific diesel “hot spots” around the region. Such “hot spots ” receive the brunt of diesel emissions, thereby raising health risks in the most impacted communities, near the ports, rail yards, warehouses and traffic corridors.
These risks were highlighted in the recently released MATES IV report from the South Coast Air Quality Management District, found here. The report has an interactive map, allowing viewers to click on their communities and see the overall cancer risk from air toxics, including diesel particulate matter.
Professor Martha Matsuoka from Occidental College outlined the history of THE Impact Project whose efforts included hosting conferences that were the impetus for developing a nationwide Moving Forward Network. Matsuoka explained that the Network serves as a resource, bringing environmental, community, academic, and other groups from around the country together to share information, resources, trainings and workshops.
To round out the featured presentations, mark! Lopez, Director of East Yard Communities for Environmental Justice, spoke to the participants, many of whom live in areas impacted by heavy diesel emissions, of the need for community change to push for environmental justice for people living around ports, freeways, and goods movement centers. Lopez spoke about not accepting “the way things are,” but changing the environment to be a healthy place in which people live, work, play and go to school.
At the conclusion of the presentations, participants discussed their concerns and questions. The following themes emerged for future activities and further information:

NEWS RELEASE: Research links tobacco smoke and roadway air pollution with childhood obesity
LOS ANGELES — New research from Keck Medicine of the University of Southern California (USC) bolsters evidence that exposure to tobacco smoke and near-roadway air pollution contribute to the development of obesity.
The study, to be posted online Wednesday, Nov. 12, 2014 in Environmental Health Perspectives, (click here) shows increased weight gain during adolescence in children exposed to secondhand tobacco smoke or near-roadway air pollution, compared to children with no exposure to either of these air pollutants. The study is one of the first to look at the combined effects on body mass index of exposure to both near-roadway air pollution and tobacco smoke. The effects were substantially greater in children exposed to both air pollutant mixtures than to either alone.
“Vehicle miles traveled, exposure to some components of the near-roadway air pollutant mixture, and near roadway residential development have increased across the United States over the last several decades corresponding to the epidemic of childhood obesity,” said Rob McConnell, M.D., professor of preventive medicine, Keck School of Medicine of USC and lead author on the study. “The potential for near-roadway air pollution to be among several factors contributing to the epidemic of obesity merits further investigation.”
The research builds on previous studies showing that exposure to secondhand smoke and particulate air pollution cause heart and lung disease.
Childhood obesity has doubled in children and quadrupled in adolescents in the past 30 years, according to the Centers for Disease Control and Prevention (CDC). Obese youth are more likely to suffer from health challenges, including high cholesterol, high blood pressure, diabetes, bone and joint problems, social stigmatization and self-esteem problems. Obesity for children is defined by the CDC as a BMI at or above the 95th percentile for children of the same age and sex.
The USC study examined exposure of more than 3,000 children to tobacco smoke during their mothers’ pregnancy and to secondhand smoke, as well as air pollution effects from busy roadways, and looked for associations with body mass index. The children were enrolled at age 10 in the Southern California Children’s Health Study, started in 1992 to study the long-term effects of air pollution on children. The children were followed yearly over an eight-year period through high school graduation at age 18. Most of the children were non-Hispanic white or Hispanic.
The researchers estimated near-roadway pollution exposure, taking into account traffic volume, how close the children lived to roadways and predominant wind direction. At study entry, a parent-completed questionnaire was used to determine lifetime tobacco smoke exposure.
“Further research is needed to determine if our findings can be replicated in other populations,” McConnell said, “and to assess both the potential contribution of combustion sources to the epidemic of obesity and the potential impact of interventions to reduce exposure.”
Funding for the research comes from the National Institutes of Health (grants P01ES022845, P30ES007048, P01ES009581, P01ES011627, P50 CA180905, R01ES016535, R01HD061968 and R03ES014046), the Environmental Protection Agency (grants RD83544101, R826708 and RD831861) and the Hastings Foundation.

Hong Kong Air Quality Researcher, Simon Ng Visits USC
Simon Ng, Chief Research Officer at Hong Kong-based nonprofit Civic Exchange, visited the Environmental Health Division on November 3 to present and share information on port air pollution surrounding Hong Kong. Civic Exchange is an “independent public policy think tank undertaking research to advance civic education and engage society to shape public policy.” During Ng’s presentation, researchers at USC Environmental Health and community partners were interested to hear about factors that make Hong Kong both similar and quite different compared to the ports of LA and Long Beach. Being surrounded by water on three sides, Hong Kong is greatly impacted by pollution that is generated from ships traveling to ports on either side of the city, not to mention ships that travel directly to Hong Kong’s port. This makes for some unique challenges in that Ng and colleagues at Civic Exchange must work with a wide variety of local and international stakeholders as they seek to reduce port emissions in and around Hong Kong.
Ng and Civic Exchange have published several reports on the public health impacts of ship emissions in the area, a hot topic for cities with large ports around the world. The reports provide a detailed look at the scope of the problem and control options; valuable information for those looking at policy options and government interventions at ports.
In recent years, Ng and Civic Exchange have partnered with the University of Hong Kong Public Health School on developing a website: The Hedley Environmental Index, which quantifies the financial burden that air pollution places on the region around Hong Kong. This unique site gives the viewer a real-time view of the ever increasing factors and costs such as deaths, hospital bed days, doctor visits and total economic loss. When visiting this site, one can also see real-time concentrations of specific pollutants around Hong Kong.
Civic Exchange is collaborating with the Urban & Environmental Policy Institute at Occidental College on a China – Environment project funded by the LUCE foundation which sponsored Simon’s week long activities in Southern California.

CENTER MEMBER RESEARCH: Dr. Heather Volk - Autism and Air Pollution
USC Assistant Professor Heather Volk is on a roll. Dr. Volk recently secured major funding from the National Institute of Environmental Health Sciences (NIEHS) to lead a study that could potentially have implications for the prevention of autism. This research seeks to further explore the role traffic-related air pollution may play in causing autistic traits and cognitive delays in children from birth to 3 years of age. This study comes on the heels of Volk's most recently published research which focused on the frequency of how a particular genetic risk factor for autism combined with prenatal exposure to air pollution may increase the incidence of autism spectrum disorders (ASD).
Drs. Volk and Rob McConnell (USC professor and air pollution epidemiologist) and colleagues from universities across the country have been awarded more than $2 million by the National Institute of Environmental Health Sciences over the course of the next four years (July 2014-July 2018) to implement their study entitled "Prospective Evaluation of Air Pollution, Cognition, and Autism from Birth Onward.” This study will combine the cohorts of two multi-year (longitudinal) studies that are being conducted at UC Davis , Kaiser Permanente in Northern California , Johns Hopkins University in Baltimore, MD and Drexel University in Philadelphia, PA. See also this USC News article about the study.
The two studies include participants who live near research sites across the country including: multiple counties in southwest Pennsylvania, New Jersey and Delaware, northeast Maryland, and people who live within a two hour radius of the San Francisco Bay Area. (MARBLES study and EARLI study)
Dr. Volk explains: “This study looks at the neurodevelopmental outcomes of children whose mothers have had one child with ASD and looks at their early development.” She adds: “Air pollution modeling techniques will be used to measure the pollution levels of kids being followed in these studies across time as well as the levels of air pollution their mothers were exposed to when they were pregnant. “ Mothers who have been exposed to similar pollution will have biomarkers in their blood analyzed for various pollutants related to traffic, including ultrafine particulate matter. Results of this research will aim to identify specific characteristics related to autism that may be caused by pollution that the children and their mothers are exposed to.
“We hope that by studying the relationships between air pollution, autism, and neurodevelopment in several areas of the country where a broad range of air pollution is present we will be able to impact the health and development of children even in highly polluted areas like Southern California,” said Volk.
"Prospective Evaluation of Air Pollution, Cognition, and Autism from Birth Onward" is an NIEHS RO1 grant funded study. Participating investigators include: USC (Heather Volk – PI, Rob McConnell), UC Davis (Irva Hertz-Picciotto), Drexel (Craig J. Newschaffer), Kaiser (Lisa Croen), Johns Hopkins (M. Daniele Fallin), and Duke (Jufeng Zhang).
In addition, on November 10, Dr. Volk, along with Linda Birnbaum, Director of the NIEHS and Leonardo Trasande, M.D., MPP Associate Professor of Pediatrics, Environmental Medicine & Health Policy, NYU School of Medicine will be testifying at a Congressional Briefing hosted by Representative David Price (D-NC). The presentation, “Ensuring a Healthy Start for Every Child: How the Environment Influences Health & Development,” is co-sponsored by Friends of the National Institute of Environmental Health Sciences, American Academy of Pediatrics, American Thoracic Society, and the National Center for Environmental Health Strategies. Stay tuned for move coverage of this important event.

EJSI Summer Institute Culminating Projects and Presentation
On Wednesday July 23 the Environmental Justice Summer Institute drew to a close. The hard work of the student and intern participants was showcased through a presentation at Los Angeles County Supervisor Mark Ridley-Thomas' 2nd District main office during the Environmental Committee meeting of the Empowerment Congress.
The youth gave a presentation (below) and showcased the videos that they made (below) that summarized their EJSI experiences. Committee members listened intently and engaged in a question/answer session with the youth participants, giving them a chance to speak about what they learned and how they think they might utilize the knowledge and experiences gained during the program. The youth were challenged to articulate not only what they learned, but the lessons they intend on taking away and applying to their lives in the near future.
Some of the lessons learned were:
- With knowledge they have a chance to make a difference.
- The communities that they live in have higher than average levels of air and noise pollution.
- All it takes is the effort of one person to make a difference to the environment such as walking to the store instead of having one's parents drive them down the street.
- Some who were already interested in environmental justice felt more equipped with knowledge and confidence to take leadership roles among their peers. One participant intends to start an Environmental Justice club at her school.
The Environmental Justice Summer Institute program is a partnership of USC Environmental Health,
Asian and Pacific Islander Obesity Prevention Alliance (APIOPA), From Lot to Spot (FLTS), and Social Justice Learning Institute (SJLI). Learn more about the institute in these blog posts and Resource Page:

Youth Pollution Monitoring Activities across the Southland
In communities around the Southland this summer and past spring, students have been learning about air pollution and doing their own hands-on monitoring. These areas included Alhambra, Hacienda Heights, Boyle Heights, Lennox, Inglewood, and more. Outreach Program coordinator Carla Truax visited several high schools and community organizations to give a presentation on “Air Pollution 101,” USC’s latest scientific research findings, and demonstrate air monitoring equipment for the students. The students then came up with creative monitoring projects of their own.
At Mark Keppel High School in Alhambra, the students were part of a youth team from a group called Asian Americans Advancing Justice (AAAJ). After monitoring around their school, which is located adjacent to the I-10 Freeway, the students then presented their research at a “Family Empowerment Festival” organized by AAAJ at Cal State Los Angeles in May.
Last year, another group of students from Mark Keppel High School did a monitoring project with
USC, interviewed experts, and created this video:
At Glen A. Wilson High School in Hacienda Heights, students in the Advanced Environmental Studies class learned about the health risks of exposure to air pollution, and how to assess the numbers of ultrafine particles near their school using monitoring devices. They also learned about the studies conducted by the environmental health sciences centers based at USC about the health effects of living or going to school near a busy freeway. Wilson High is located just a few feet from the 60 Freeway. These high school visits were organized by partner organization Asian and Pacific Islander Obesity Prevention Alliance.
Legacy L.A. is a non-profit organization focused on youth and leadership development which offers academic support to students in Boyle Heights (on the East side of LA), in particular to students who live at Ramona Gardens. After a training session by USC on the health effects of air pollution, the youth talked about some critical issues they are working on: access to healthy food, environmental justice, and safe walkable streets in their community. The group also had questions about creating a buffer zone to help mitigate the effects of traffic emissions from the freeway that borders their housing development and a newly constructed playground. Using what they had learned, the youth developed an action plan for addressing the pollution issues in their community and presented it at a town hall meeting for key policy and decision makers in June. The meeting was covered by Boyle Heights Beat.
Environmental Justice Summer Institute (EJSI) is a program focused on educating, engaging, and empowering youth to be environmental health leaders in their neighborhoods of Inglewood, Hawthorne, and Lennox. The youth developed hands-on experience with two days of ultrafine particle pollution and noise monitoring at 14 locations around their neighborhoods. The students chose locations for monitoring and mapped them before setting out for their field work. The selected locations included places they live, learn, and hang out, such as parks, schools, and homes. These areas are in the flyover path for jets landing at LAX airport.
stirring in my mind was that there is not much being done to keep our homes safe. I only wonder how
our community will be if we do not take action, so I think people should be more aware of the dangers around them.” –Vanessa Sanchez
“While doing the air and noise pollution, I was surprised a few times by the measurement and the
locations. I never thought our communities were that polluted by these moving engines. What surprised me more was the bus pollution measurement was quite low. But some locations were heavily polluted and can have a negative effect on people’s health.” –Khanh Nguyen
“My emotion about knowing the air pollution was “surprise!” because I didn’t know that our air was
not as clean as it should be. For example the beach has 4,000 pt/cc [number of particles per cubic centimeter] of ultrafine particles on average. I asked myself why doesn't the city enjoy that kind of healthy air? All the data gathered concerned me about the environment and it made me see that we have a problem.” –Abigail Diaz
[Note: the average levels of ultrafine particles in Lennox and Inglewood was 45,000 pt/cc.]
“My thoughts and emotions weren’t thrilled because I was expecting to get the result that we got
because I know the community. The only one I was surprised was at the beach because it was really low. It was 2,000-6,000 (pt/cc).” –Eder Juarez

I asked myself why doesn't the city enjoy that kind of healthy air? All the data gathered concerned me about the environment and it made me see that we have a problem.” –Abigail Diaz
[Note: the average levels of ultrafine particles in Lennox and Inglewood was 45,000 pt/cc.]

because I know the community. The only one I was surprised was at the beach because it was really low. It was 2,000-6,000 (pt/cc).” –Eder Juarez
The Environmental Justice Summer Institute program is a partnership of USC Environmental Health,

NEWS RELEASE: Research raises new concerns about air pollution impacts at Los Angeles International Airport
Study shows air quality from ultrafine particles extends further than demonstrated by previous research
PRESS: Los Angeles Times , Daily Breeze, For more news coverage, click over to our summary on Storify.
The study, published May 29, 2014, in the journal Environmental Science and Technology (ES&T) and conducted with University of Washington (UW) researchers, found a doubling of ultrafine particle number concentrations extended east more than 10 miles downwind from the airport boundary over a 20-square mile area, encompassing communities including Lennox, Westmont, parts of South L.A., Hawthorne and Inglewood, and, in certain wind conditions, areas south of LAX.
“Our research shows that airport impacts extend more than 5 times further than previously assumed,” said Scott Fruin, D. Env., lead researcher and assistant professor of preventive medicine at the Keck School of Medicine of USC. “Effects from planes that are landing appear to play a major role in this large area of impact.”
To put this large area of impact into perspective, the researchers calculated that one-quarter to one-half of the entire L.A. County freeway system produces an equivalent increase in ultrafine particle numbers on a concentration-weighted basis.

“LAX may be as important to L.A.’s air quality as the freeway system,” said Fruin. “The impact area is large, and the airport is busy most hours of the day. That makes it uniquely hard for people to avoid the effects of air pollution in affected areas.”
Most previous research on the air quality impacts of airports focused on measuring air quality near where jet takeoffs occur. Takeoffs produce immense plumes of exhaust but only intermittently, and pollution concentrations downwind have been observed to fall off rapidly with distance. The assumption has been that total airport impacts also fall off rapidly with distance. The new research finds that this assumption is wrong.
The study found that concentrations of ultrafine particles were more than double over 20 square miles compared to background concentrations in nearby areas outside the area of LAX impact. Also, ultrafine particle number concentrations four times higher than background extended a distance of six miles.
“Given the existing concern about the possible health effects of urban ultrafine particle levels, living in an area with two to four times the average L.A. levels of ultrafine particles is of high public health concern,” said first author Neelakshi Hudda, Ph.D., research associate in preventive medicine at the Keck School.
Ultrafine particles are currently unregulated, but are of concern because they appear to be more toxic than larger particles on an equal mass basis in animal and cellular studies, and because they appear able to enter the bloodstream, unlike large particles that lodge in the lungs.
The research team used vehicles equipped with special measurement devices to capture data not available using traditional fixed monitors. The team was able to take moving measurements for more than 5 hours under consistent wind conditions to fully capture the extent of the impact boundaries.
“Other airports generally have less steady wind directions, which would make these measurements more difficult,” said Hudda. “Similar impacts are probably happening, but their location likely shifts more rapidly than in Los Angeles.”
“The on-shore westerly winds cause this impact regularly in communities east of LAX, because the impact’s location corresponds to the wind direction,” Hudda added. “In the winter months, when the winds were different, impacts were measured south of the airport during northerly winds.”
The research was funded by the National Institute of Environmental Health Sciences.
UW researchers included Tim Larson, Ph.D. and Tim Gould, Ph.D. in the Department of Civil Engineering, and Kris Hartin, Ph.D. in the Department of Environmental and Occupational Health Sciences.

Environmental Justice Summer Institute: Youth Workshops
Four Southern California groups are excited to announce a new partnership to jointly sponsor an inaugural Environmental Justice Summer Institute (EJSI):
This EJSI curriculum is focused on educating, engaging, and empowering the youth to be agents of change in their own neighborhoods.
• Educate: Youth will learn about environmental justice and its disproportionate impact on people of color communities through workshops, presentations, and community tours.
• Engage: Youth will participate in an interactive workshop with urban planner James Rojas and conduct on-the-ground monitoring and mapping. With partner USC the youth will develop hands-on experience to not only map out and identify highly polluted locations in their own neighborhoods, but to also have an opportunity to use air and noise monitoring equipment to track pollution levels.
• Empower: Throughout the program, the youth will work with Digital Rain Factory on digital storytelling to educate and engage their communities around the environmental concerns they have. The digital stories they create will also be used to advocate to their local elected officials, for changes they identify are needed through their summer program.
Curriculum to be covered:
• Researching environmental justice in our community
• Becoming environmental justice youth leaders
• Learning how to make videos for a cause
• Monitoring air and noise levels
• Informing public policy 101: The low down on our local policies
• Being a dynamic speaker
• Engaging the Community
Stay tuned for more exciting details of this pilot program! Search #EJSIFellows on Twitter to keep up on the latest developments, photos and more.
