摘要
锡是排列在白金、黄金及银后面的第四种贵金属,在地壳中平均含量只有0.004%,是一种希贵的金属,也是一种重要的战略物质。为满足国民经济生产发展的需求,我国每年需要大量的进口锡矿石。缅甸(佤邦)生产的锡矿石100%经孟连勐啊口岸进口到我国,为全面掌握缅甸(佤邦)产锡矿砂中有害元素铅Pb、砷As、汞Hg等有害元素的含量情况,防范有害元素随进口锡矿石进入我国境内。论文通过生产场地实地调查和抽样检测分析孟连口岸进口缅甸产锡矿石中有害元素的携带情况和分析有害元素对人体健康及生态环境带来的危害,根据有害元素的特性提出相应的预防建议。
Tin is the fourth precious metal arranged behind platinum,gold and silver.It has an average content of only 0.004% in the earth’s crust.It is a precious metal and an important strategic substance.In order to meet the needs of national economic production and development,China needs a large amount of imported tin ore every year.100% of the tin ore produced in Myanmar（Shan State）is imported into China through the Menglianyu port,in order to fully grasp the content of harmful elements such as lead Pb,arsenic As and mercury Hg in the tin ore produced in Myanmar（Shan State）.Prevent harmful elements from entering the territory of China with imported tin ore.Through the field investigation and sampling test of the production site,the paper analyzes the carrying of harmful elements in the tin ore imported from Myanmar at Menglian Port and analyzes the harm caused by harmful elements to human health and ecological environment.According to the characteristics of harmful elements,the corresponding prevention suggestions are put forward.
