时下,老百姓的菜篮子丰富了,然而,菜的质量却下降了。来自农业部的数据显示:我国农药年用量为80至100万吨。其中,使用在农作物、果树、花卉等方面的化学农药约占95%以上。长期而大量地滥用化学农药,不仅造成了环境污染,而且严重地危害着人体的健康。农药之害猛于虎小小的农药缘何对人类造成如此大的危害?据专家介绍,在施用农药过程中,农作物、畜类、水产等动植物都可能受到农药的污染。因此,目前几乎不存在哪个人群,在某种程度上未受到农药的污染。有些农药性质稳定、残留期长,一旦造成污染便很难消除。如 DDT,在土壤中如果自行消失掉95%,需要4至30年。目前在空气、水体、土壤和食物中都发现了 DDT。人们进食残留有农药的食物,如果污染较轻、吃入的数量较小时,不会出现明显的症状,但往往有头痛、头昏、无力、恶心、精神差等表现;当农药污染较重、进入体内的农药量较多时,会出现明显的不适,如乏力、呕吐、 Nowadays, people’s rich food basket, however, the quality of food has declined. Data from the Ministry of Agriculture show that China’s annual pesticide use is 80 to 1,000,000 tons. Among them, the use of chemical pesticides in crops, fruit trees, flowers and other aspects accounted for more than 95%. Long-term and large-scale abuse of chemical pesticides, not only caused by environmental pollution, but also seriously endanger the health of human beings. Why pesticides fierce Tiger small pesticide Why human caused so much harm? According to experts, in the process of pesticides, crops, livestock, aquatic plants and animals may be contaminated by pesticides. As a result, there is hardly any population at the moment and to some extent is not contaminated with pesticides. Some pesticides are stable in nature and have a long residual period. Once the pesticide is contaminated, it is hard to eliminate it. DDT, if it disappears 95% of its own in the soil, it takes 4 to 30 years. DDT is currently found in air, water, soil and food. People eat pesticide residues of food, if the pollution is light, eat a small number of hours, there will be no obvious symptoms, but often have headache, dizziness, weakness, nausea, poor mental performance; when heavy pesticide pollution, Into the body when the amount of pesticides, there will be obvious discomfort, such as fatigue, vomiting,
