CONCLUSIONS/DISCUSSIONS 

TYPE OF CONCERN: HEALTH ECOTOX 

LEVEL OF CONCERN: 1-2 3 

KEYWORDS: 

LUNG 

IRR-E,L,MM,GI 

UNCERT-DEVEL 

AQUATOX-A,C 

SUMMARY OF ASSESSMENT 

FATE: Solid 

S = Disp.(E); VP @ 25C (mm) < 1.0E-6(E); H < 1.00E-8(E) 

POTW removal (%) = 50-90 via sorption 

Time for complete ultimate aerobic biodeg > mo 

PBT Potential: P3B1T1 

Sorption to soils/sediments = strong 

*CEB FATE: Migration to ground water = slow 

 

HEALTH: Absorption is nil through the skin based on 

physical/chemical properties. Expect poor absorption through the 

GI tract and moderate absorption through the lungs based on 

analogs. Based on the submitted data, the PMN compound is an eye 

irritant (irritation took 4 to 7 days to clear). It also 

expected to be irritating to the lungs, GI tract, and mucous 

membranes. The PMN compound is expected to cause lung effects 

based on surfactant activity if inhaled. There is uncertain 

concern for developmental toxicity by analogy to . 

*CEB HEALTH: Low moderate concern (Inhalation only). 

TOXICITY DATA: negative in Salmonella 

acute oral study in rats - no deaths at 2000 mg/kg, piloerection, 

hunched posture, soft to liquid feces, ungroomed appearance, 

increased salivation 

eye irritant 

slight skin irritant 

ECOTOX: Predicted (P) and measured (M) toxicity values in mg/L 

(ppm) FOR INTENDED PRODUCT WITH are: 

fish 96-h LC50 = 3.4 P 

daphnid 48-h LC50 = 640.0 P 

green algal 96-h EC50 = 170.0 P 
fish chronic value = 0.500 P 

daphnid ChV = 100.0 P 

algal ChV = 3.7 P 

Predictions are based on SAR-nearest analog method for in the

ingredients and mean measured concentrations; hardness <180.0 

mg/L as CaCO3; and TOC <2.0 mg/L; 

moderate concern for toxicity; 

assessment factor = 10.0 

concern concentration = 0.050 mg/L (ppm) for intended product 

Predicted (P) and measured (M) toxicity values in mg/L (ppm) FOR 

WORST CASE PRODUCT WITH are: 

fish 96-h LC50 => 0.300 P 

daphnid 48-h LC50 = 4.6 P 

green algal 96-h EC50 = 13.0 P 

fish chronic value => 0.050 P 

daphnid ChV = 0.710 P 

algal ChV = 3.3 P

mg/L; 

high concern for toxicity;

product 

*CEB ECOTOX: All releases to water; run two PDMs: CC = 0.050 

mg/L (ppm) for intended product and CC = 0.005 mg/L (ppm) for 

worst case product; 

*CEB ECOTOX: All releases to surface waters.
