摘    要:通过对温州市场上19种蔬菜、水果的123个样品中重金属Hg,As,Pb,Cd的含量状况的调查研究,探明了这4种重金属元素在蔬菜、水果中的含量状况及分布规律.结果表明,镉是温州市场上的蔬菜、水果中的主要污染元素,某些品种的超标率高达50%,蔬菜含量超过国家标准最高的为1.7倍,水果达1.6倍.铅的污染次之,虽然没有发现超标的样品,不过潜在的污染风险还是存在的.汞和砷的含量都较低,潜在的污染风险不大.

关 键 词:蔬菜  水果  重金属  温州市

Abstract:A survey was conducted to detect the contents of heavy metals in 123 samples of 19 kinds of vegetables and fruits that were collected from the markets of Wenzhou city. The results showed that cadmium is the main pollutant element in vegetables and fruits in this city, the standard-exceeding ratio of cadmium in some kinds of samples was up to 50%, the highest contents of cadmium in the vegetables and fruits were 1.7 times and 1.6 times over the national sanitary standards, respectively. The pollution degree of lead in the samples was lower than that of cadmium, but the samples of standard-exceeding lead contents was not found. The potential trend of lead pollution was existed. The contents of mercury and arsenic in the samples were very low, the pollution hazards of these two heavy metals wee less.
Keywords:vegetables  fruits  heavy metals  wenzhou city
