LEGEND FOR NEW CHEMICALS EXPOSURE REPORT 

This new chemicals exposure report was prepared by the Exposure Assessment Branch (EAB) of the 

Economics, Exposure and Technology Division, Office of Pollution Prevention and Toxics, USEPA. 

The goals of these reports are to calculate conservative (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 manufacturing and processing releases that occurred at the 

same site. 

For each consumer product use exposure scenario, whether exposure is to the user directly or to the 

general population/environment, the maximum exposure values are calculated and presented together. 

In addition to the exposure values 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) chemicals 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.

Remarks: Water releases may instead be to stack or landfill. Water releases are overlap of three releases. Fugitive 

air release is overlap of six releases. Incineration (stack) and fugitive release volumes are below their respective 

threshold amounts of concern, so no further assessment of those pathways.
