Carcinogenicity: Not listed as a carcinogen by IARC, NTP, OSHA
Mutagenicity: No evidence for mutagenic effects under standard testing
Reproductive Toxicity: Studies show no reproductive risks at realistic exposure levels
Long-term Effects: Chronic exposure data insufficient; safety limits based on acute and subchronic studies
Other Effects: No known neurotoxicity or organ-specific effects in standard models
Aquatic Toxicity: Moderately toxic to aquatic life, LC50 (fish): 10–50 mg/L (96 hr); EC50 (daphnia): 5–25 mg/L (48 hr)
Persistence: Moderately persistent in soil, limited water solubility reduces mobility
