Efectos del herbicida Paraquat sobre el zooplancton


, : Efectos del herbicida Paraquat sobre el zooplancton. Iheringia Serie Zoologia30 Setembro; 92(3): 47-56

The effects of 0.1; 0.2; 0.4 and 0.8 mlPQ/L were analized on a zooplankton community, to determine the most sensitive species and to analize the occurrence of physical abnormalities. A total of 40 taxa were determined. Paraquat affected significantly the zooplankton density but not the species richness. A progressive state of deformation of these organisms was also observed. Paraquat showed to be highly toxic for the zooplankton, so this herbicide should be strictly regulated in aquatic and terrestrial ecosystems.

Soybean fatty acid epoxide hydrolase (EC 3.3.2.3) was found to possess remarkable and unique stereochemical features. After complete hydrolysis, this enzyme converts racemic or enantiomerically enriched cis-9,10-epoxy-12(Z)-octadecenoic and cis-12...
