The toxicity of diquat.

Clark, D. G. and Hurst, E. W. (1970). Brit. J. Industr. Med., 27, 51-55. The toxicity of diquat. The acute toxicity of diquat has been assessed in several species. The oral LD50 ranged from about 30 mg/kg in cattle to 231 mg/kg in the rat. Large doses of diquat gave rise to symptoms indicative of an action on the central nervous system, but smaller doses did not suggest an obvious mode of actio...

Eukaryotes in Arctic and Antarctic cyanobacterial mats.

Cyanobacterial mats are commonly found in freshwater ecosystems throughout the polar regions. Most mats are multilayered three-dimensional structures with the filamentous cyanobacteria embedded in a gel-like matrix. Although early descriptions mentioned the presence of larger organisms including metazoans living in the mats, there have been few studies specifically focused on the microbial euka...

Chronic Exposure to Diquat Causes Reproductive Toxicity in Female Mice

Diquat is a bipyridyl herbicide that has been widely used as a model chemical for in vivo studies of oxidative stress due to its generation of superoxide anions, and cytotoxic effects. There is little information regarding the toxic effects of diquat on the female reproductive system, particularly ovarian function. Thus, we investigated the reproductive toxic effects of diquat on female mice. C...
