Abstract:
The distribution and consumption risk of Cu,Pb and Cd were investigated in six freshwater fishes-Silver Carp(Hypophthalmichthys molitrix),Bass(Lateolabrax japonicus),Mandarin Fish(Siniperca chuatsi),Bream(Parabramis pekinensis),Crucian Carp(Carassius aumtus) and Grass Carp(Ctenopharyngodon idellus)-from the main market in Hefei.The results showed that concentrations of Cu,Pb and Cd in the muscles of all the fishes were lower than the standard values in the national NY 5073-2006 Limited Quantity of Poisonous and Harmful Contents of the National Pollution-Free Aquatic Products,national standard GB 2762-2005 Limited Quantity of Contaminants in Foods,as well as those established by the Australian National Health and Medical Research Council(ICRP).The total consumption risk of the heavy metals in the six fishes was lower than 5.0×10-5 a-1,as recommended by ICRP.The health risks of Cu,Pb and Cd in the muscles of the six fishes in the main market of Hefei were acceptable for people’s consumption.
