粤北大宝山矿床为铁、铜、铅、锌、钼等多种金属和硫的综合性矿床,其矿山活动对矿区周围的生态系统和人体健康带来了巨大的影响。由酸性矿山废水带来的多种具有潜在毒性的重金属通过食物链进入人类生存的环境,造成水体、土壤、大气和生态环境的污染。本文对大宝山附近流域的水体、土壤、粮食果蔬的重金属含量及污染情况进行述评,为矿山治理、环境与经济的可持续发展以及人类健康安全提供理论依据。
The Da Baoshan deposit in northern Guangdong is a comprehensive deposit of various metals and sulfur such as iron, copper, lead, zinc and molybdenum, and its mining activities have a tremendous impact on the ecosystem and human health around the mining area. A variety of potentially toxic heavy metals brought by acidic mine waste water enter the environment of human existence through the food chain, causing water, soil, atmosphere and ecological pollution. This paper reviews the heavy metal contents and pollution of water body, soil and grain fruits and vegetables in Dabaoshan watershed and provides a theoretical basis for mine management, sustainable development of environment and economy and human health and safety.
