摘　　要：The distribution of mercury,an environmentally important toxicant,has been evaluated in a time dependent manner in different tissues of white rat and a freshwater teleost,Anabas testudineus.Sampling was performed at 15 min,2,6 and 48 h post injection(im)of 203Hg mercuric nitrate.Radioactivity of the 5%tissue homogenate,serum and bile was measured in a Gamma Counter.The rate of 203Hg accumulation is higher in fish immediately after administration which,however,is more or less of equal rate in the later period of observation in both the experimental animals.Partitioning of 203Hg occurs in a species specific manner with higher levels recorded in the brain and gonad of white rat.Spleen,liver and kidney,however,are the major tissues to accumulate mercury in both the species.The present study highlights that kidney is the target site of mercury retention with a higher kidney/liver ratio of mercury.
