Challenges of Protecting Children from Pesticide Exposure

On January 20, 2015, the Honorable Josh Green, Chairman of the Hawaii Senate Committee on Health convened an informational briefing on the health risks of pesticide exposure, particularly as they relate to children and other sensitive populations in Hawaii. “Exposure to pesticides has been linked to diseases from autism to cancer,” Green said, "and may be especially harmful to children and pregnant women, so it is very important for us to understand the risks of pesticide exposure to Hawaii's most sensitive populations if we are going to make the right decisions to protect them." The Senate Health Committee heard evidence presented by experts on public health, epidemiology, and toxic exposure, including: Dr. Michael J. DiBartolomeis - Chief, Occupational Lead Poisoning Prevention Program & California Safe Cosmetics Program, California Department of Public Health. “Hawaii’s children should be able to play outside without having their health put at risk,” Green said, “and we can provide them a safe and healthy environment to grow up in if we make the right choices now."

Survey and Toxicology of Chemicals in Tempur-Pedic® Products and Materials

cover report.JPG

I analyzed the results of laboratory testing data for chemicals present in certain Tempur-Pedic® products and materials to determine whether these chemicals have the reasonable potential to cause harm to consumers and users. Chemicals included volatile organic compounds such as the human carcinogen formaldehyde, flame retardants, and others. In addition, I evaluated the marketing claim that Tempur-Pedic® products and materials  are “hypoallergenic” or free of chemicals that can trigger allergies and/or asthma.

Biomonitoring: Essential Tool for Public Health Policy and Development

This is a presentation I developed to educate policymakers and program managers on the importance of biological monitoring of chemicals to promote public health and more effective chemical regulation policy. Please note that this is an edited version of the complete presentation, removing slides specific to the audience and details about program planning and priorities.

Committee on Energy and Commerce, Health Subcommittee Hearing on Examining the Current State of Cosmetics

On Tuesday, March 27, 2012, the House Energy and Commerce’s Subcommittee on Health held the first congressional hearing in 30 years concerning the safety of cosmetics. At that time, as chief of the California Safe Cosmetics Program, I was invited to testify and describe some findings of the California Safe Cosmetics Program, which I was primarily responsible for establishing in 2006 as the first state cosmetics-regulatory program in the nation. In my testimony, I briefly addressed the following:

  1. growing public concern about the safety of cosmetic products;
  2. challenges in evaluating cosmetic product safety;
  3. benefits of the California Safe Cosmetics Act of 2005; and
  4. five elements that I believe would assist in the evaluation of the safety of cosmetics and protecting public health.

Toward the 21st Century: Planning for the Protection of California's Environment (California Comparative Risk Project)

Participants in the California Comparative Risk Project were charged with identifying environmental threats of the greatest ecological, human health, and societal concern using the risk ranking model. However, agreeing that risk is not the only factor that should be considered, the study also examined how economics, pollution prevention, environmental justice, education, and public participation contribute to environmental decision-making. The unique inclusion of this aspect in the study was in response to a growing debate nationally and in California about the limitations of a risk-ranking model for setting environmental priorities. Overall, the report is a compilation of two and one-half years of work involving nearly 300 volunteers representing a wide diversity of backgrounds including industry, agriculture, community groups, county and state government, universities, and environmental organizations. Recommendations to Cal/EPA are ncluded in this report. The results of this report formed the basis for legislation creating an environmental justice advisory committee in Cal/EPA.

Survey and Toxicology of Pesticides Applied to the Mid-Pacific Country Golf Course

I reviewed and analyzed the inventory and application records of pesticides used by Mid Pacific Country Club (MPCC) golf course in Kailua, HI from 2003-2012 in order to assess the health implications associated with applying these pesticides to residential property on or adjacent to the golf course.
