The distribution and difference of K,Na,Fe,Zn,Cu,Cd,Pb and Cr in the anatomical parts(body muscle,pincers and leg food,gill,liver and pancreas) of adult male and female mitten crab were studied.Nutrition of minerals and pollution of heavy metals were evaluated.The results showed that K and Na contents were the highest,and Fe,Zn and Cu were higher than Cd,Pb and Cr.The significant differences for the content of same mineral in different anatomical parts ware found,but all of mineral contents are high in gill.Most mineral contents had no significant difference between the same anatomical parts of adult male and female crab,except for Cd,Cu,Na,K and Cr in gill and Cr in muscle.The mitten crab was found to be very good food source of minerals,but was severely polluted by Pb and Cd.
