摘  要：
目的:了解廊坊及其周边地区羊体、饲料、水源、土壤常见重金属污染现状。方法:采用石墨炉原子吸收分光光度法和氢化物发生器-原子吸收光谱法检测样品中铅、砷、汞、镉、铬的含量。结果:羊肉、肝脏、肾脏样品中铅、砷、镉、铬均有检出,且均无超标,汞均未检出;饲料、饮水、土壤中铅、砷、汞、镉、铬均检出,但均符合标准。结论:廊坊及其周边地区羊体内重金属含量基本处于安全水平,但有个别样品因受饲料、环境等因素的影响,重金属含量接近临界值或超标。

摘  要：
Objective: To understand the current situation of common heavy metal contaminations in sheep carcass,feed,drinking water and soil in and around Langfang area.Methods: The contents of lead,arsenic,mercury,,cadminum and chromium in samples were determined by graphite furnace atomic absorption spectroscopy or hydride generation atomic absorption spectroscopy.Results: Detectable and safe levels of lead,arsenic,cadminum and chromium and no detectable levels of mercury were found in mutton,liver or kidney.Each heavy metal showed a detectable level in feed,drinking water and soil despite being in line with the safety standards.Conclusions: Heavy metal contents of sheep carcass in and around Langfang area are generally at safe levels although few samples are close to the critic values or even exceed the standards,which arises from feed and living environments.
