Abstract
This report addresses the effects of coal-derived trace and radioactive elements. A summary of our current understanding of health and environmental effects of trace and radioactive elements released during coal mining, cleaning, combustion, and ash disposal is presented. Physical and biological transport phenomena which are important in determining organism exposure are also discussed. Biological concentration and transformation as well as synergistic and antagonistic actions among trace contaminants are discussed in terms of their importance in mobility, persistence, availability, and ultimate toxicity. The consequences of implementing the President's National Energy Plan are considered in terms of the impact of the NEP in 1985 and 2000 on the potential effects of trace and radioactive elements from the coal fuel cycle. Areas of needed research are identified in specific recommendations.
摘要
本报告阐述了煤中微量及放射性元素的影响。文中总结了我们目前对煤炭开采、洗选、燃烧及灰渣处理过程中释放的微量及放射性元素对健康和环境影响的认识。还讨论了在确定生物体接触情况方面具有重要意义的物理和生物传输现象。从微量污染物在迁移性、持久性、可利用性及最终毒性方面的重要性出发，讨论了生物浓缩和转化以及微量污染物之间的协同和拮抗作用。根据1985年和2000年国家能源计划（NEP）对煤炭燃料循环中微量及放射性元素潜在影响的作用，考量了实施总统国家能源计划的后果。在具体建议中明确了所需的研究领域。
