 Health:

 Health Summary: Absorption is moderate all routes based on analogs. 

Based on the submitted 5-day inhalation study, the identified metabolites are 

 The in vitro studies indicate 

the PMN material is not corrosive, but it is expected to be irritating based on its reactivity with

water. There is a marginal concern for oncogenicity for the metabolites. In the 

submitted 28-day inhalation study, there were clinical chemistry changes and effects to the liver 

in males. Low moderate concern. 

 Test Data: negative in Salmonella and E coli

negative for dermal sensitization in the mouse local lymph node assay

not corrosive to the eyes, in vitro, Bovine Corneal Opacity and Permeability test

not corrosive to the skin, in vitro, human three dimensional epidermal model

acute oral study in rats - no deaths or signs of toxicity at 2000 mg/kg

5-day inhalation study in rats, 10,000 ppm - no deaths or signs of toxicity; urine samples

 Exposure scenario titles consist of release activity followed by exposure calculation abbreviation. 2 Release activities are from engineering report's Manufacturing (Mfg), Processing (Proc) and Use release activity 

labels. 

Multiple release activities are combined in one exposure scenario if their releases occur at same location. 3

 Exposure calculations are Acute Dose Rate (ADR), Lifetime Average Daily Dose (LADD), and Probabilistic 

Dilution Model (PDM). There may be one, two, or all three exposure calculations per exposure scenario. 

CC is the aquatic concentration of concern. 

4

 This column displays concentration values for the 7Q10 streamflow, which is defined as the average streamflow of 

the 7 consecutive days of lowest flow within a 10 year period.

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, (2) max 

LADD, (3) max PDM. 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.
