## LEGEND FOR NEW CHEMICAL S EXPOSURE REPORT
This new chemicals exposure report was prepared by the Exposure Assessment Branch (EAB) of the Economics, Exposure and Technology Division, O ffice of Pollution Prevention and Toxics, USEPA. The goals of these reports are to calculate conserva tive (protective) estimates of exposure endpoints for consumers, the general population, and the environment. For each exposure scenario to industrial releases, the following three endpoints are calculated: (1) maximum possible acute concentrations and doses (2) maximum possible chronic concentrations and doses (3) for water releases ≥ 20 days, the probability of exceedence of the aquatic concentration of
concern These endpoints are identified by abbreviations on the Release Activity line, e.g., (1) max ADR (acute dose rate) , (2) max LADD (lifetime average daily dose) , (3) max PDM (probabilistic dilution model) . Depending on the release inputs, these endpoints may be calculated and presented on the same page or different pages. That is, a release activity ID of mfg; max ADR, max PDM, max LADD indicates that all the exposure endpoints were calculated from common manufacturing release values; conversely, a release activity ID of mfg &proc; max ADR indicates that only the maximum acute exposure values were calculated for manufactur ing and processing releases that occurred at the same site. For each consumer product use exposure scenario, whethe r exposure is to the user directly or to the general population/environment, the maximum expos ure values are calculated and presented together. In addition to the exposure valu es above, EPA policy directs that exposure and release values be compared to criteria threshold values for Exposure-based and PBT Exposure-based cases. Exposure-based (YX) cases (those with ≥ 100,000 kg/yr production volume) Criteria are exceeded under the following conditions: Presence in consumer product with likely exposure ≥ 3E-3 mg/kg/d exposure via air, fish ingestion or drinking water ≥ 10,000 kg/yr release to environment (post-treatment) ≥ 1,000 kg/yr release to water (post-treatment) Persistent, Bioaccumulative, Toxic (PBT) chemical s of P2B2 rating or higher and production volume ≥ 20,000 kg/yr Criteria are exceeded as for YX cases, with the following differences: ≥ 2,000 kg/yr release to environment (post-treatment) ≥ 200 kg/yr release to water (post-treatment) Bolding rules in the Report: Values for endpoints above that are also health or eco concerns are bolded.STA NDARD REVI EW EXPOSURE REPORT
