background: anzali wetland has been subjected to high levels of pollution due to contamination from several industrial sites in addition to agricultural chemicals. mussels have been widely used for monitoring pollution in aquatic ecosystems, because they, as filter feeders, bioaccumulate pollutants. therefore we decided to evaluate anodonta cygnea for its application as a bio-monitor for copper...

crude oil is enriched in polycyclic aromatic hydrocarbons (pahs). many pah analogs have proved to potentially damage dna. dna damage can be assessed using various biomarkers to find out the degree of genotoxicity of pollutants following in vitro exposure. in this research the comet assay and micronucleus (mn) test were used to detect dna damages and cytogenetic changes following crude oil expos...

Previous communications from this laboratory have been concerned with an attempt to elucidate the ionic basis of action potential production in the central nervous system of Anodonta cygnea. This eulamellibranch mollusc was chosen for these studies as it appears to be the possessor of the most dilute blood so far described in the Animal Kingdom (Potts, 1954) and, for this reason, presents some ...

diazinon is one of the highly consumed organophosphorous pesticides. it inhibits cholinesterase enzyme in animal tissues. due to permanent residence in agricultural drainage channels, the swan mussel (anodonta cygnea) can be considered as one of the most suitable indicators of such pollutants. at the present study, acethyle cholinesterase activity of a. cygnea was measured when exposed to vario...

Our understanding of the ionic basis of axonal conduction has been largely derived from studies carried out on vertebrate and invertebrate animals which possess conventional body fluids containing relatively high concentrations of sodium and other inorganic ions. Apart from some recent studies on a phytophagous insect (Treherne, 1965 a, b; Treherne & Maddrell, 1967 a, b) we have very little kno...

nowadays, bivalves are used in monitoring levels of heavy metals in aquatic environments. the aim of this study was to investigate bioaccumulation of heavy metals zinc (zn) and chromium (cr) in the internal organs of anodonta cygnea. for this purpose, bivalve specimens were collected from semeskandeh region, sari, and then in laboratory, were exposed to 125 µg l-1 concentrations of each metal f...
