Brazilian freshwater ecosystems are continuously exposed to pesticides and domestic sewage. The Uruguay River was chosen for this study because of its international importance, as it flows through Brazil, Argentina, Uruguay. It receives contaminants such residues. Thus, the aim assess accumulation in muscle fish Astyanax jacuhiensis, biochemical responses, presence water. In total, seven were registered water from both river sites. Eight detected muscle. responses showed that brain lipid...
Abstract Cyprinus carpio were exposed under field conditions to 20.87 µg l −1 of commercial herbicide bispyribac‐sodium (Nominee®, SC), during 7, 21 and 72 days. Enzymatic parameters such as catalase (CAT), glutathione S ‐transferase (GST) acetylcholinesterase (AChE) activities, well thiobarbituric acid‐reactive substances (TBARS) protein carbonyl contents studied in different tissues. After 7 days exposure, GST activity decreased. At the same period, brain AChE increased, but a reduction...
Agricultural practices are directly related to the use of pesticides, which indiscriminately and without due care may contribute occurrence numerous intoxications. Several studies have demonstrated relationship certain pesticides oxidative stress therefore, in recent years developed methods analysis several biomarkers cellular damage that can be measured quantified. In this context, objective study was evaluate possible changes biochemical markers: glutamic aspartate aminotransferase (AST),...
Mycorrhizae are mutualistic associations between fungi and plant roots. These symbiotic abundant occur in 75 to 80 % of plants. Ectomycorrhizal very important ecosystems, because their association with plants different species helps nutrients water absorption, as well protection the host against pathogens abiotic stresses. Most ectomycorrhizal belong Basidiomycota class, such following genera: Amanita, Hebeloma, Hysterangium, Laccaria, Lactarius, Rhizopogon, Russula, Scleroderma, Suillus,...
