Metals released into the environment as a result of anthropogenic activities such as mining can pose a threat to natural ecosystems and human health. Environment Canada has identified several elements such as copper (Cu), nickel (Ni), zinc (Zn), chromium (Cr), selenium (Se) and mercury (Hg) as potential contaminants. After release into the environment, biogeochemical processes including precipitation/ dissolution, sorption/desorption and redox transformations can affect the mobility, toxicity and bioavailability of these pollutants. Identifying the sources and understanding the fate of contaminants is important to develop effective containment and remediation strategies.

采矿等人为活动释放到环境中的金属可能对自然生态系统和人类健康构成威胁。加拿大环境部已确定铜(铜)、镍(镍)、锌(锌)、铬(铬)、硒(Se)和汞(Hg)等元素为潜在污染物。在释放到环境中后，包括沉淀/溶解、吸附/解吸和氧化还原转化在内的生物地球化学过程会影响这些污染物的移动性、毒性和生物有效性。查明污染物的来源和了解污染物的去向对于制定有效的遏制和补救战略非常重要。
