一、我省农药残留的现状和存在问题农药是重要的农业生产资料,在农业生产减灾防灾中发挥着重要的作用。但农药也是有毒物质,若不合理使用,会产生残留问题,污染环境和农产品,危害人畜健康和生命安全。广东省是一个农业大省,耕地面积227.81万公顷,1999年全省粮食作物播种面积达327.47万公倾,如果种植面积达94.65万公颂,蔬菜种植面积达96.12万公顷。据统计,1999年全省农作物病虫草鼠等有害生物的发生面积为1373.10万公顷次,防治面积达1690.89万公顷次,全年农药商品使用量近7万吨。长期以来,由于不合理使用农药,以及对农药残留监督管理缺乏有效手段,致使我省农药残留问题比较突出,每年因农药残留超标造成人畜中毒的事例时有发
First, the status of pesticide residues in our province and existing problems Pesticide is an important means of agricultural production, agricultural production in disaster prevention and disaster prevention play an important role. However, pesticides are also toxic substances. If they are not used properly, they will cause residual problems that pollute the environment and agricultural products and endanger the health and safety of people and livestock. Guangdong Province is a large agricultural province with a total area of 2,287,100 hectares of arable land. In 1999, the sown area of grain crops in the province was 3,227,700 hectares. If the planting area was 9,456,500 kilometers, the planting area of vegetables reached 961,200 hectares. According to statistics, in 1999, pests such as pests, weeds and rats in the whole province took up to 13.731 million hectares of pests and control areas reached 16,908,900 hectares. The annual use of pesticides amounted to nearly 70,000 tons. For a long time, due to the unreasonable use of pesticides and the lack of effective means of supervising and managing pesticide residues, pesticide residues in our province have become more prominent. Every year, cases of human and animal poisoning caused by excessive pesticide residues occur frequently
