Review of Potential Impact on Health and Environmental Quality from Metals Entering the Environment as a Result of Coal Utilization,

摘要

The study reflects the detailed examination of inorganic emissions from coal combustion. It includes total mass of particulates,chemical composition of the particulates emitted,and the deposition using a mathematical model derived from St. Louis urban studies. This study seeks to determine whether the emissions released could pose a threat to any facet of biological systems with which they might interact. For this study, a credible upper boundary for the concentrations of flyash elements ultimately to be found in air,water,or soil was established. Several models were developed for estimating atmospheric and hydraulic dispersion and soil/plant availability. Several risk considerations are taken into account,once the emission is deposited at the earth's surface. The potential health hazard for man and the special sensitivity of green plants or other organisms which are part of the natural environment are considered.
