Formula
C9H12N203S

Bentazon is expected to enter surface water by run of from application sites. It has a moderate water solubility of 500 mg/l and a low tendency to adsorb to soils and sediments. In water it can be rapidly broken down by sun light (photodegradation). Its environmental half-live varies between 24 hours and 4 months, depending on the environmental conditions. It can also be biodegraded. [2] [3]

It has a very low a tendency to bioaccumulate.

Bentazon has a low toxicity to most aquatic animals. Concentrations above 100 mg/l are necessary to cause acute toxicity to fishes. Invertebrates are most vulnerable; mussels die at concentrations above 20 mg/l. Concentrations above 5 mg/l might affect phytoplankton. [4]
