Environmental Health Investigations branch

People in different environments where they might be exposed to chemicals.

Welcome

The Environmental Health Investigations Branch (EHIB) studies and explains how the health of our environment affects our health. We provide information that can help reduce human exposure to harmful environmental risks. Our mission is to protect the health of all Californians by identifying environmental hazards, partnering with communities to build their capacity, and promoting healthy environments.

  • California Asthma Dashboard. California Breathing launched a new and improved online interactive data tool, the California Asthma Dashboard. The tool has been redesigned to improve navigation and simplify downloading charts and data sets. The California Asthma Dashboard displays state- and county-level data on: asthma prevalence; asthma emergency department visits, hospitalizations, insurers; and asthma deaths.

  • Asthma Management Academy Infographic (PDF). California Breathing is pleased to release an infographic that highlights the successes of the Asthma Management Academy (AsMA), an evidence-based training for community health workers (CHWs) and other health educators to learn how to deliver asthma education for individuals and families with asthma.

  • Are you looking to practice purposeful, community engagement? EHIB developed two new resources for government agencies!: Created for public agencies, the Guide for Engaging Communities for Health Equity and Environmental Justice (PDF) offers promising practices and effective strategies for comprehensive community assessments, meaningful partnerships, community-based research, accessible communications, and equity-conscious interventions. The accompanying Toolkit for Engaging Communities for Health Equity and Environmental Justice (PDF) provides additional templates, resources, field-testing guides and more to work together with community in achieving common goals. Contact us at AskEHIB@cdph.ca.gov for support in implementing these strategies within your agency.

  • ATTENTION ALL LANDLORDS! New Mold Booklet Requirement For 2022!: Starting on January 1, 2022, all residential landlords in the state will be required to provide tenants with a mold booklet developed by the California Department of Public Health. The booklet, Information on Dampness and Mold for Renters in California, describes the increased risks to health that may result from exposures to dampness or mold in buildings. Available in English (PDF) and Spanish (PDF), the booklet also helps tenants understand the causes of mold problems, how to identify signs of dampness and mold, and how to report suspected problems to their landlord. For more information, please visit CDPH's Indoor Air Quality web page.

  • Fumigation Tenting. Learn how to protect yourself and your family from harmful chemicals when your home is tented and fumigated for termites or other pests.

  • Public Health Impact of Prescribed Fire: Report on Listening Sessions. Brief report (PDF) and full report now available. The State plans to increase the use of prescribed fires to reduce the risk of high-intensity wildfires and restore forest health. Although prescribed fire offers an important tool to reduce wildfire risks, concerns exist about the public health implications of smoke generated by prescribed burning. EHIB held two virtual listening sessions to hear from community members in high wildfire risk areas in Nevada and El Dorado counties about their knowledge, attitudes, and perceptions of the public health impacts of prescribed fire and wildfire, and to learn about their messaging preferences.
