(1) Tests involving acute exposure of rats, mice, rabbits, and guinea pigs have demonstrated carbaryl to have moderate to high acute toxicity from ingestion and moderate acute toxicity from dermal exposure. The high dose was increased to 3600 ppm during week 41 and subsequently to 5400 ppm from week 45 2010). Phenothrin, also called sumithrin and d-phenothrin, is a synthetic pyrethroid that kills adult fleas and ticks.It has also been used to kill head lice in humans. Acute animal tests in rats, mice, and guinea pigs demonstrate propoxur to have high acute toxicity by inhalation exposure and high to extreme acute toxicity by ingestion.4 Chronic Toxicity Chronic inhalation exposure has resulted in depressed 114-26-1 - ISRUGXGCCGIOQO-UHFFFAOYSA-N - Propoxur [INN:BAN] - Similar structures search, synonyms, formulas, resource links, and other chemical information. In animal studies, propoxur has moderate acute toxicity consisting of anticholinesterase effects (U.S.EPA, 1997b). shown to be of low acute toxicity. Hazard Summary. Acute overexposure to propoxur can inhibit cholinesterase, an enzyme necessary for … Cancer Information: Propoxur phenol Propoxur: IARC Carcinogens Recent studies suggest that N, N-diethyl-meta-toluamide (DEET) is an acetylcholinesterase inhibitor and that this action may result in neurotoxicity and pose a risk to humans from its use as an insect repellent. Studies in humans have shown that depression of erythrocyte cholinesterase (rather than plasma cholinesterase) is a significant indicator of exposure to propoxur… This is determined through the LD50 which is a standard of measurement of the lethal dose required to kill 50% of the sample population. The impli-cation of these studies for humans are not known. . Prenatal exposure to pyrethroids and propoxur have been linked to neurodevelopmental disorders in early life [17], while in animal studies, chronic toxicity of propoxur … .
