Abstract:Cadmium and Chromium in pork and pork liver was determined by graphite furnace atomic absorption spectrometry. Copper in pork, pork liver and feed was determined by flame atomic absorption spectrometry. The qualified rate of cadmium in pork and pork liver was 100%, the detection range was 0.01~0.16 mg/kg. The qualified rate of chromium in pork and pork liver was 100%, the detection range was 0.10~0.88mg/kg. The qualified rate of copper in pork was 100%, the detection range was 0.23~0.87 mg/kg. The qualified rate of copper in pork liver was 50.0%, and the detection range was 4.90~78.9 mg/kg. The content of copper in 20 pig feed for fattening hog was 0.29~69.0 mg/kg and the qualified rate was 95%. It was suggested that the situation of copper remains in pork liver was not optimistic, and the copper content exceeded standard was one twentieth in pig feed.
