摘要：

The present study was conducted to analyse microcystin concentrations in Lakshmikund pond, Varanasi, India, as well as in carp and catfish of the pond. The concentrations of microcystin were found well above the WHO guidelines (1 A mu g/L) both for the dissolved and particulate fractions of bloom samples. The microcystin concentrations in different organs of carp and catfish were in the following sequence; liver > gut > kidney > gall bladder > gills > muscles and gut > liver > kidney > gall bladder > gills > muscles, respectively. The bioaccumulation of microcystin in carp and catfish was negatively correlated with body weight, and showed species specificity. The higher bioaccumulation of microcystin in muscles of catfish (> tenfold) over carp indicates a possible threat to human beings on consumption of catfish. Therefore, to avoid animal and human intoxication, routine analyses of microcystin in pond water as well as fishes are strongly recommended.
