Emissions into the atmosphere of particular concern to plume transport and dispersion, from tall stacks, are the gaseous products SO., NO and NO.. In addition significant quantities of fine particles may be also emitted into the atmosphere.

The Effects of Weathering and Natural Heating on Trace Elements of Coal,mperature (< 30°C) for several years. In contrast, natural heating is a high temperature event and occurs due to implacement of plutonic or invasion of volcanic rocks into coal seams often for short durations or self-burning of coal seams due to forest fire or lightning.

There is a comprehensive account of trace elements in coals, including tabulated data for the 24 elements of environmental interest
