【摘要】 目的研究公路沿线动物源产品铅镉污染状况与相关因素。方法选择福建省龙岩市境内319国道沿线的动物源产品为研究对象,依据国标方法检测铅镉含量。结果污染区7种动物源产品的铅镉含量分别为0.002 5~0.068 6和0.000 05~0.005 22 mg/kg,总平均含量分别为0.022 70和0.001 37 mg/kg,分别是对照区的3.15和5.48倍;不同品种的鸭肉铅镉含量不同,依次为红脸鸭肉>水鸭肉>土番鸭肉;铅镉在动物体内不同组织的分布不均衡,鸡骨、鸭骨、兔骨的铅含量分别是鸡肉、鸭肉、兔肉的130.28,353.48,139.68倍;鸭骨、兔肾的镉含量分别是鸭肉、兔肉的17.40和2 641.06倍;不同饲养方式、饲养场所与公路边不同距离与动物的铅镉含量无明显关系。结论公路沿线动物源产品已受到不同程度的铅镉污染,其含量与禽畜的品种和部位密切相关。更多还原

【Abstract】 Objective To study lead and cadmium pollution of animal products from areas along traffic road and its related factors.Methods Samples of animal product from areas along Longyan domestic 319 federal highway were collected and detected for lead and cadmium contents based on national standard method.Results The lead and cadmium contents of 7 kinds of animal product in contaminated zone were between 0.0025-0.0686 mg/kg and 0.00005-0.00522mg/kg with the means of 0.0227mg/kg and 0.00137mg/kg,respectively.The means were 3.15 and 5.48 times higher than that of samples from control areas.The lead and cadmium contents were different between meats of different ducks with a descending order of red painted-face duck,water duck,aborigines duck.The lead and cadmium distributions in animal tissues were imbalanced.The lead contents of chicken bone,duck bone,rabbit bone were 130.28,353.48,139.68 times higher than that of the meat,respectively.The cadmium contents of duck bone,rabbit kidney were 17.40 and 2641.06 times higher than that of the meats,respectively.The lead and cadmium contents were not related to different feeding method and the distance between farming area and traffic road.Conclusion The animal products from areas along traffic road are polluted with lead and cadmium.The lead and cadmium contents vary greatly in different tissues and organs of the animal exposed to the pollution.更多还原
