NOTES & KEY ASSUMPTIONS:

Generated by the 06/07/2005 version of ChemSTEER. 

 

 

 

POLLUTION PREVENTION CONSIDERATIONS:

P2 Claims: As a flame retardant on plants, the PMN substance

appears to be environmentally friendly and not harm grass or

tree leaves. It appears to have an LC50 of 500 mg/L, which is

above the limit of 100 mg/L that the US Forest Service requires.

 It is a more effective flame retardant than diammonium

phosphate, used in current products. The PMN substances causes

wood in plants to char, rather than to burn, keeping a fire from

spreading. For use as a fire retardant in plastics, the PMN

substance will be used to replace chlorinated or brominated

compounds. The substance is thermally stable up to 325°C, and

can be processed into polymers such as nylons, olefins and

polyesters up to 350°C. The substance causes a plastic to char

instead of burning, which reduces the amount of smoke and vapors

released during exposure to flames. P2REC: CRSS forward.

1 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 daily 

streamflow of the seven consecutive days of lowest flow within a ten year period. 

Remarks: This is a Post-Focus exposure report based on original IRER (dated 03/19/09) with updated CC=229ppb.
