TOXICITY OF DIOCTYLTEREPHTHALATE

Abstract

Dioctylterephthalate is a general-purpose plasticizer, has low toxicity, and does not irritate the mucous membranes of the eye and the skin; the maximum nonlethal dose (DL0) for dioctylterephthalate after intragastric administration is set at 10,000 mg/kg. Indicative safe exposure level for dioctylterephthalate in ambient air in urban and rural settlements is recommended at 0.5 mg/m3. Substance has low acute toxicity; the maximum inactive dose is set at 4 mg/kg. The substance has low solubility in water (0.4 μg/l), does not affect the dynamics of biochemical oxygen consumption. Threshold concentration in water on organoleptic characteristic is set at 0.25 mg/l as for low hazard substances.
