Effect of pH on the toxicity and bioconcentration of sulfadiazine on Daphnia magna.

The antimicrobial sulfonamide sulfadiazine has in the last decades been detected in environmental water bodies, both surface and ground water. Since pH in the environment may vary considerably, this study examined the toxicity of the amphoter sulfadiazine towards Daphnia magna at pH levels of 6.0, 7.

Dichlobenil and 2,6-dichlorobenzamide (BAM) in the environment: what are the risks to humans and biota?

Dichlobenil is a herbicide widely used for weed control, mainly in non-agricultural areas and in the aquatic environment. When released into the environment, dichlobenil can undergo many processes such as vaporization to air, binding to soil and sediment, as well as degradation to a number of new compounds. The main metabolite is 2,6-dichlorobenzamide (BAM) which is water soluble and causes ground water contamination.

Analysis and environmental concentrations of the herbicide dichlobenil and its main metabolite 2,6-dichlorobenzamide (BAM): a review.

Dichlobenil is an herbicide which has been applied in many countries for weed control in non-agricultural areas such as railroads, car parks and private gardens. In the aquatic environment it has been used for control of floating aquatic weeds. Dichlobenil is relatively persistent in the environment, and primarily bound to solid matrices.
