Abstract: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.
