在国内外重金属监测技术的基础上对环境污染事故中重金属（铜、铅、锌、砷、汞、铬、镉）的两种主要快速监测方法进行了研究。研究结果表明：比色法可测试铜、铅、锌、镉、六价铬5种重金属，且精密度与准确度均较好；阳极溶出伏安法（ASV）可测试铜、铅、锌、镉、砷、汞6种重金属，但测定六价铬时偏差较大；除六价铬和铜外，阳极溶出伏安法的测试范围较比色法宽，且检出限较低；阳极溶出伏安法可同时测定镉、铅、铜3种金属，具有较好的适用性。
在國內外重金屬鑑測技術的基礎上對環境汙染事故中重金屬（銅、鉛、鋅、砷、汞、鉻、鎘）的兩種主要快速鑑測方法進行瞭研究。研究結果錶明：比色法可測試銅、鉛、鋅、鎘、六價鉻5種重金屬，且精密度與準確度均較好；暘極溶齣伏安法（ASV）可測試銅、鉛、鋅、鎘、砷、汞6種重金屬，但測定六價鉻時偏差較大；除六價鉻和銅外，暘極溶齣伏安法的測試範圍較比色法寬，且檢齣限較低；暘極溶齣伏安法可同時測定鎘、鉛、銅3種金屬，具有較好的適用性。

Based on the monitoring technologies of heavy metals in the world,two major rapid methods for monitoring the heavy met-als(Cu,Pb,Zn,As,Hg,Cr and Cd)in environmental pollution accidents were studied in this paper.The results showed that:Col-orimentric method can test the content of Cu,Pb,Zn,Cd and Cr (VI),which reveals a good precision and accuracy;Anodic strip-ping voltammetry(ASV)can test the content of Cu,Pb,Zn,Cd,As and Hg,but has a large discrepancy when applied in testing Cr (VI);ASV has a larger test range and lower detection limit than colorimentric method with exception of Cu and Cr(VI);ASV can test the content of Cd,Pb and Cu simultaneously,which also displays a good applicability.
