- 摘要:
- 为了解和掌握西安市农业产地环境农田灌溉水重金属污染现状，对西安市9个涉农区县产地环境农田灌溉水重金属安全状况进行调查分析，抽取292个农田灌溉水，对农业产地环境条件标准中的严格控制的毒理性指标中的总铅、总镉、总汞和总砷进行了测定，采用单因子和尼梅罗综合污染指数法进行评价。结果表明：长安区、临潼区、高陵区、阎良区、蓝田县、周至县、未央区和灞桥区8个区县等级为清洁水平，只有户县污染程度为警戒限，污染水平为尚清洁，整体未受到大面积污染，农田灌溉水的毒理性指标符合农业产地环境农田灌溉水的要求。
- Abstract:
- In order to understand and grasp the current situation of heavy metal pollution of irrigated agricultural land in Xi’an,the safety situation of heavy metals in irrigated agricultural land in nine agricultural areas and counties in Xi’an was investigated and analyzed,and 292 farmland irrigation waters were extracted.Total lead,total cadmium,total mercury and total arsenic in strictly controlled toxicological indicators in environmental condition standards of agricultural origin were measured and evaluated by single factor and Nimeiluo index index method.The results showed that the eight districts and counties in Chang ’an district,Lintong district,Gaoling district,Yanliang district,Lantian county,Zhouzhi county,Weiyang district and Baqiao district had clean levels,and only the pollution level in Hu County was a warning limit.The level of pollution was still clean,and the whole area was not contaminated.The toxicity index of farmland irrigation water meets the requirements of farmland irrigation water.
