- It is possible these pesticides interact to increase human health hazard. The report investigates the potential for interactive effects among these agents. The report first introduces the concept of cumulative exposure and risk assessment, and summarizes the current state of the science and policy on this issue. Then, the report assesses the health risks from simultaneous or sequential exposures to Telone, metam sodium, and chloropicrin, identifies health effects reported for each of these chemicals, and assesses the mechanistic bases for potential interactive effects. This section of the report identifies critical data gaps that impede full evaluations of the cumulative health risks from exposure to these three fumigant pesticides, and recommends expanding the range of studies and computational techniques to better understand and characterize interactive effects that might occur at the cellular and molecular levels and result in enhanced adverse health outcomes.
- Some residents of California are exposed to these pesticides simultaneously and/or sequentially. The report investigates use of these three fumigants, and concludes application of multiple pesticides is common, and surrounding communities are likely exposed.
- DPR is required to assess the risk of cumulative exposure and protect public health, but is not currently doing so. This section reviews the adequacy of existing risk assessment approaches and regulatory policies toward cumulative exposures. It suggests actions regulators in California could take to develop science-based risk assessments of chemical mixtures that would guide regulatory agencies in setting exposure limits that protect human health from cumulative exposures.
Gotta wonder the 2016 US Presidential Candidates think about this?
