Menlo Park City Council, As referenced in the prior email, please find below the written opinion of Dr. Larry Rose, M.D. M.P.H., Occupational/Environmental Medicine, former Chief of the Medical Unit for CAL/OSHA for 28 years. Thank you. ----- Forwarded Message ----- *From:* Larry Rose *Sent:* Wednesday, November 8, 2017 8:24 PM This is a fact based review of 1 3 butadiene. Any exposure to multiple substances at any concentration regardless of what regulatory agencies allow would effect the cancer, reproductive, and endocrine health of people exposed. Any trace amount of 13 butadiene, plus volatile organic compounds, plus carcinogenic metals, plus endocrine disruptors creates a toxic brew of concurring substances that could well be not just additive but multi-plicative in increasing these health risks. Addressing each individual substance's allowable level of exposure would be very misleading. This is true of a number of chemicals and health impacting physical substances. Recent scientific information regarding endocrine disrupting chemicals has set traditional toxicology on its head and frequently goes unaddressed in any health risk analysis. The age groups and health status of at risk members of exposed populations is of upmost importance in drawing any conclusions regarding overall probable health risks. https://ntp.niehs.nih.gov/ntp/roc/content/profiles/butadiene.pdf I have been extensively reviewing the state Office of Environmental Health Hazard Assessment's in progress field studies to assess the levels of health hazards from exposures to the various artificial turf users. The report by by Millennium is deficient in a number of ways. I invite you to contact OEHHA to review the March 2017 meeting that laid out the very extensive, thorough, well designed study to scientifically arrive at a fact based risk assessment by mid 2019. I therefore do not accept the Millennium study as in any way an acceptable study proving the safety of "Astroturf". Please feel free to quote me at the meeting and you can print out the above statement to hand out to the school board.
