Health and Air Pollution

This page updated February 22, 2007


Air pollution continues to be an important public health concern. A  number of air pollutants, coming out of a variety of industrial processes, impact the health of California residents. Air monitoring shows that over 90 percent of Californians breathe unhealthy levels of one or more air pollutants during some part of the year. The California Air Resources Board (ARB) establishes health-based ambient air quality standards to identify outdoor pollutant levels that are considered safe for the public - including those individuals most sensitive to the effects of air pollution, such as children and the elderly.
The ARB has set standards for eight "traditional" pollutants, such as ozone and particulate matter. In addition to setting standards, the ARB identifies other air pollutants as toxic air contaminants (TACs) - pollutants that may cause serious, long-term effects, such as cancer, even at low levels. Most air toxics have no known safe levels, and some may accumulate in the body from repeated exposures. The Board has identified about 200 pollutants as air toxics, and measures continue to be adopted to reduce emissions of air toxics. Both traditional pollutants and toxic air contaminants are measured statewide to assess programs for cleaning the air. The ARB works with local air pollution control districts to reduce air pollution from all sources.

Ambient Air Quality Standards
Information on the workshops, locations,drafts and other information on upcomming State Ambient Air Quality Standards can be found at this location.
ARB - Board Health Updates
The Air Resources Board staff provides monthly updates regarding the latest research findings on health and air pollution.
ARB - Chair's Seminar Series
The Air Resources Board gives and hosts many presentations and seminars on various topics. The announcements for the seminars, videos of the webcasts and most of the presentations will be stored in this area for download.
Air Toxics Program
Here you can find web pages on the ARB's Toxic Air Contaminant Identification and Control Programs. Information is also available for the air toxic control measures, the Air Resources Board’s Air Toxics Hot Spots program, asbestos, diesel exhaust and dry cleaning, the Federal Clean Air Act Title III Activities and air toxics emission inventory database activities.
Asthma and Air Pollution
Asthma is a serious chronic lung disease that appears to be on the rise in California, the United States and many other countries around the world. The prevalence of asthma in the U.S. has increased by more than 75 percent since 1980; children and ... read more
Children's Environmental Health Protection Act
The Children's Health Environmental Protection Act (Senate Bill 25) established specific requirements to determine if children are adequately protected from the harmful effects of air pollution. These pages summarizes the activities conducted under SB 25.
Children's Health Research
Children may be more vulnerable to harmful impacts from air pollutants than adults for several reasons. They breathe more air than do adults, relative to their body size, and have greater metabolic growth requirements. Their activities create both health and exposure scenarios that are unique to children. On this page, we present the studies that are relevant to the children of California.
Community Health
This program identifies air pollution's effects on children's health, assesses the public risks in California communities and identifies actions to reduce these public health risks.
Fact Sheets
These are some of many fact sheets ARB has produced to relay the scientific information to the public in a "user friendly" manner.
See our new Health Effects of PM and Ozone Air Pollution (PDF - 229 KB) Fact Sheet.
Harbor Communities Monitoring Study
The goal of the Project is to develop improved tools for measuring pollutant concentrations in the air and detecting areas where concentrations of these pollutants are high.
Health and Clean Air Newsletter
The Newsletter provides information on the health impacts of air pollution which are of concern to the citizens of California.
Health Effects of Diesel Exhaust
Overall, diesel engine emissions are responsible for the majority of California's known cancer risk from outdoor air pollutants. In addition, diesel soot causes visibility reduction and is a potent global warmer.
Health Effects Research
The Air Resources Board has an active research program to investigate the health effects associated with air pollution exposure, particularly in citizens that may be more sensitive to air pollution effects, such as children and the elderly. Here you will find information on some of our recent and ongoing air pollution health effects research.
Health Outcome Data
Health outcome data links are presented on this page as a resource for researchers and the public. The links presented on this page have been collected from State and National Health agencies outside of the ARB. No air pollution data has been factored into the any of the information in the links provided on this page.
Health Effects of Traffic
Many people are affected by the effects of traffic.This page has of links to the studies that have been done and are ongoing that involve some sort of measurement of the possible exposure to air pollution from traffic on major roads
Indoor Air Quality and Personal Exposure Assessment Program
The California Air Resources Board (ARB) carries out a non-regulatory Indoor Program that includes sponsored research, exposure assessment, development of indoor air quality guidelines and public education and outreach. The goal of the Indoor Program is to identify and reduce California's exposures to indoor air pollutants.
Quantified Health Impacts of Air Pollution- NEW
The Air Resources Board has quantified the health impacts associated with air pollution exposure, particularly ozone and particulate matter. Here you will find information on some of our recent and ongoing works.
Research Activities
The Air Resources Board has a research program to investigate the health effects associated with community air pollution, especially in people most likely to be harmed. These effects may result from brief exposures or long, even life-long exposures. More information on this program can be found at this location.
School Health
Information on this page is related to school health, including studies of school bus exposures and environmental health conditions in classrooms. Findings of these studies and practical actions schools can take to reduce pollutant exposures can be found here. Two videos on the health effects of air pollution can be viewed as well.
Vulnerable Populations Research Program (VPRP)
The Vulnerable Populations Research Program's (VPRP) will support ARB’s regulatory and non-regulatory programs that aim to protect all California residents, including those subpopulations considered especially vulnerable, from the adverse effects of air pollution. A major emphasis of the VPRP is to identify susceptible subpopulations, to quantify the degree to which their health is compromised, and to characterize their exposures to air pollutants. The ARB has released the Vulnerable Populations Research Program's (VPRP) 2003 Progress Report and Research Plan which presents the ARB’s current activities as well as priorities for future research efforts in this program.
