潜在有毒金属和类金属对地球生态系统的污染是一个全球性问题。它可能会随着我们星球上不断增长的人口及其对自然资源（如水，食物，能源，废物处理场）和金属制品的需求而增长。通过呼吸、食物和饮用水摄入重金属/类金属污染对健康的影响通常是长期的，并以多种方式表现出来。这些包括，例如，精神敏锐度的丧失，运动控制的丧失，关键器官功能障碍，癌症，慢性疾病和伴随的痛苦，丧失能力，最后死亡。在人类、动物和植物中的有毒金属触发疾病的发病率和地理分布（流行病学）在历史上和现代都有很好的记录。环境地球化学家及其同事在环境科学中的作用是科学地评估如何在源头或原位管理金属类金属，以减轻或消除其对生活人群的负面健康影响。这是通过确定来源和开发物理，化学和生物控制模型的动员，相互作用，沉积和积累的潜在有毒金属/准金属在源系统和地球生态系统。在这个知识库的基础上，环境科学家（例如地质学家、化学家、生物学家、环境工程师、物理学家/气象学家）共同努力，
Contamination of the earth's ecosystems by potentially toxie metalsl metalloids is a global problem. It will likely grow with our planet's increasing populations and their requirements for natural resources (eg, water, food, energy, waste-disposal sites) and metals-based goods. The health impacts of pollution from the ingestion of heavy metals/metalloids via respiration, food, and drinking water are most often long-term and manifest themselves in many ways. These include, for example, disminution of mental acuity, loss of motor control, critieal organ dysfunction, cancer, chronie illnesses and concomitant suffering, incapacitation, and finally death. The incidence and geographie distribution of disease (epidemiology) has been well-documented historieally and in modern times for toxic metalstriggered diseases in humans, animals and vegetation. The role of the environmental geochemist and colleagues in environmental sciences is to scientifically evaluate how to manage metalsl metalloids at sources or in-situ so as to alleviate or eliminate their negative health impacts on living populations. This is initiated by identifying sources and by developing models of the physieal, chemieal and biologieal controls on mobilization, interaction, deposition and accumulation of potentially toxie metals/metalloids in source systems and earth ecosystems. Prom this knowledge base, environmental scientists (eg, geologists, chemists, biologists, environmental engineers, physicists/meteorologists) work together to develop
