【摘要】：了解江西省蔬菜中重金属污染情况及农药残留水平的规律,及时发现蔬菜类食品中的安全隐患,为科学防控提供参考。在江西省11个设区市根据人口分布、蔬菜生产种植情况各抽取1个区(县)作为监测点进行采样,检测重金属及农药污染情况。2012—2014年江西省蔬菜中重金属污染总超标率3.6%,以铅、镉的污染为主,总砷、总汞未超标,但2012—2014年铅、镉污染有逐年增高现象,差别有统计学意义(P0.05)。铅污染最严重的为甘蓝类蔬菜,镉污染最严重的为茄果类蔬菜,不同种类蔬菜的铅、镉超标差异有统计学意义(P0.05)。2012—2014年江西省蔬菜中农药残留总检出率为42.3%,超标率为1.2%,16种农药有不同程度的检出,检出率最高的为氯氰菊酯。加强对环境污染的综合治理,建立完善农药快速溯源制度,加强蔬菜中农药及重金属监测的频率,重点防患蔬菜中高毒农药残留风险。
[Abstract]:To understand the pollution of heavy metals and the level of pesticide residues in vegetables in Jiangxi Province, and to find out the hidden dangers of safety in vegetables in time, and to provide reference for scientific prevention and control. According to the population distribution, 1 district (county) was sampled from 11 districts (counties) in Jiangxi Province according to the population distribution. The pollution rate of heavy metals in vegetables in Jiangxi Province from 2012 to 2014 was 3.6, with lead and cadmium pollution mainly, total arsenic and mercury not exceeding the standard, but the pollution of lead and cadmium increased year by year from 2012 to 2014. The difference was statistically significant (P0.05). Lead pollution is the most serious for cabbage vegetables, cadmium pollution is the most serious for eggplant vegetables, different kinds of vegetables lead, The total detectable rate of pesticide residues in vegetables of Jiangxi Province from 2012 to 2014 was 42.3%, the rate of exceeding the standard was 1.2% and 16 pesticides were detected in varying degrees, the highest detectable rate was cypermethrin. We should strengthen the comprehensive control of environmental pollution, establish and perfect the fast traceability system of pesticides, strengthen the monitoring frequency of pesticides and heavy metals in vegetables, and focus on preventing the risk of high toxic pesticide residues in vegetables.
