Description
Summary:Simazine, a member of the triazine group, is registered in California for weed control in soils where a wide range of crops will be (or are) planted. The health risks from simazine use in California were recently assessed by the California Department of Pesticide Regulation (CDPR) for all potential (acute and long-term) exposure scenarios relevant to Californian residents and workers. The results of the CDPR risk assessment indicate that current exposure levels in many of the scenarios under consideration are not health protective for the people in California. The main objective of the present summary report (i.e. , case study) was two-fold, both for offering a forum to advance further scientific discussion: (1) to highlight the toxicity and exposure data as well as the assumptions used in the CDPR simazine risk assessment and then (2) to systematically requalify the uncertainties and complexities involved in terms of the toxicity and exposure appraisals given in that risk assessment. In both attempts, the focus was more on residential exposures for young children and women of child-bearing age in that simazine was reportedly seen to exhibit neuroendocrine effects across a variety of species.
