This study aimed to test the performance of the amphipod Gammarus locusta (L.) in chronic sediment toxicity tests. It constitutes part of a multi-level assessment of chronic toxicity of estuarine sediments, integrating organism and population-level endpoints with biochemical markers responses. Here we account for organism and population-level effects, while biomarker responses were reported in ...

Solar simulator irradiation of an aqueous suspension of prednisone, a widely prescribed drug, produces seven photochemical derivatives. The compounds have been identified on the basis of their physical features. All the chemicals have been tested to evaluate their toxic effects on freshwater organisms from different trophic levels. The rotifer Brachionus calyciflorus and two crustaceans, the cl...

Although the recent extensive use of quinacrine in the therapeutic and prophylactic treatment of malaria has focused attention on its possible chronic toxicity, no study of its lifetime effects on laboratory animals has been reported. Experiments (1, 2) conducted for shorter periods of time have shown that quinacrine can cause extensive pathological lesions in animal tissues, especially when re...

pesticides are widely used in iranian agriculture and this has made a major toxicological concern among health professionals. the objective of this study is to explore national data about pesticides toxicity. all relevant databases such as google scholar, pubmed, and scopus in a time period of 1960 to 2012 were searched for the keywords “pesticides, iran, environment, and population studies”. a...
