OPP completed a cumulative exposure assessment for the OP and for the NMC pesticides in the mid-2000’s as required under the Food Quality Protection Act of 1996. Since that time, we have been tracking these cumulative exposures over time on year by year basis using the PDP data by means of a “toxicity-adjusted exposure index”. This is being done for 1 to &lt;3 year old children at the high end of the exposure profile (99.9<sup>th</sup> percentile) and is intended to be a future component of the Agency’s Report on the Environment. The index begins in 1995 and continues through 2019 and appropriately accounts for (i.e., incorporates) food consumption, relative toxicity, and concentrations of the OP and NMCs in PDP commodities that together account for &gt;98% of the diet. These toxicity-adjusted exposures allow the agency to track trends in OP and NMC cumulative exposures through food since the time FQPA was passed and a number of mitigation and other actions have been instituted.
