一、案例与问题2006年春耕在即,但广东省翁源县新江镇上坝村村民却迟迟没有下地。原因在于这里的农田已经出现了严重的重金属污染。而污染的原因就是大宝采矿区的洗矿废水没有经过任何处理就排入河流流进附近的农田和村庄。土地的污染导致农作物减收,重病频发,贫穷、疾病交织。上坝村153.3多公顷(2300多亩)农田逐年减少,目前已丢荒耕地13.3多公顷(200多亩),全村23.3多公顷(350亩)鱼塘全部废弃。更令人不安的是,由于长期受污染,上坝村癌症高发期正在到来,中山大学的医疗和环境专家调查排除了癌症遗传性的可能,而是长期摄入重金属所致。而重金属进入人体的途径,一是食用污染农地产出的高残留的农作物,二是饮用水。在村民不断上访控诉的压力下,广东省、韶关市和大宝山矿区共筹资1400多万元修建上坝村饮水工程。据悉,这一工程上马后,村里将与大宝山矿区签一个永久协议,就是今后大宝山矿区不再因污染给上坝村任何费用。
I. CASE AND QUESTION Spring is coming to an end in 2006, but villagers in Shangba Village, Xinjiang Town, Wengyuan County, Guangdong Province have yet to step down. The reason is that there have been serious heavy metal pollution in farmland here. The reason for the pollution is that the mining wastewater in Dabao mining area is discharged into the rivers and flows into nearby farmlands and villages without any treatment. Land pollution led to crop reduction, frequent serious illness, poverty, and disease interweaving. Over 153.3 hectares (2,300 mu) of farmland in Shangba Village have been reduced year by year. At present, 13.3 hectares (200 mu) of wasteland have been abandoned and all the 23.3 hectares (350 mu) of fish ponds in the village have been abandoned. Even more disturbing is that due to the long-term pollution, the high incidence of cancer in Shangba Village is approaching, Sun Yat-sen’s medical and environmental experts have ruled out the possibility of cancer genetic, but the long-term intake of heavy metals. The way heavy metals enter the human body, one is the consumption of contaminated agricultural land output of high residual crops, the second is drinking water. Under the pressure of the villagers’ continuous petitions, Guangdong Province, Shaoguan City and the Dabaoshan mining area jointly raised over 14 million yuan to build Shangba Village drinking water project. It is reported that after the project was launched, the village will sign a permanent agreement with the Dabaoshan mining area, that is, the Dabaoshan mining area no longer charges any fees for the dam village in the future.
