为了解我市海产品镉的含量，我们对鱼类、软体动物类、贝壳类、甲壳类进行了调查。共查３０种１４３份样品，平均含镉量分别：鱼类为０．０４１ｍｇ／ｋｇ（（最高为０．０７ｍｇ／ｋｇ）；软体动物类为０．０４６ｍｇ／ｋｇ（最高为０．０９ｍｇ／ｋｇ）；甲壳类０．０４５ｍｇ／ｋｇ（最高为０．０７ｍｇ／ｋｇ）；贝类０．１７４ｍｇ／ｋｇ（最高为０．２９ｍｇ／ｋｇ），说明我市海产品受到一定程度的污染，鱼类含镉量在国家标准（≤０．１ｍｇ／ｋｇ）范围内。贝类含镉量较高，调查６份扇贝样品，其含镉量均大于鱼的标准。根据调查结果，对海产品镉污染的危害和预防，以及贝类的镉允许含量等问题作了讨论。
In order to understand the city’s seafood cadmium content, we conducted a survey of fish, molluscs, shellfish, crustaceans. A total of 143 samples were examined for 30 species, with an average of 0.041 mg / kg for fish (up to 0.07 mg / kg) and 0.046 mg / kg for molluscs (up to 0.09 mg / kg ); Crustacean 0.045mg / kg (up to 0.07mg / kg); Shellfish 0.174mg / kg (up to 0.29mg / kg), indicating that the city’s seafood was polluted to some extent, Cadmium content in the national standard (≤0.1mg / kg) within the range of high content of cadmium in shellfish, scallop 6 samples were investigated, the cadmium content were greater than the standard of fish.According to the survey results, the cadmium pollution of seafood Hazards and prevention, as well as the allowable content of cadmium in shellfish and other issues were discussed.
