In order to assess pollution caused by leaching of some minor and major elements during ash transport through the pipeline, two sets of samples (six samples each) were subjected to a modified sequential extraction. The first set consisted of coal ash samples taken immediately after combustion, while the second set was obtained by extraction with river water, imitating the processes that occur in the pipeline.

2017-12-6 Coal mining. Mining operations can negatively impact water supplies, often with long-lasting effects. The fundamental issue involves contamination of nearby rivers, lakes, and aquifers by what comes out of a coal mine—usually highly acidic water containing heavy metals like arsenic, copper, and lead. The process is known as acid mine drainage.It happens when certain substances (typically ...

2021-5-8 Pollution from coal utilization. Coal utilization is associated with various forms of air pollution.During the incomplete burning or conversion of coal, many compounds are produced, some of which are carcinogenic.The burning of coal also produces sulfur and nitrogen oxides that react with atmospheric moisture to produce sulfuric and nitric acids—so-called acid rain.

2017-4-25 The coal industry has a significantly negative environmental impact on the land, water, and air. It is responsible for producing pollution such as ash, sludge, slurry, arsenic, mercury, uranium, and other heavy metals that pollute the air and waterways. Additionally, coal processing has a negative effect on human health.

The results show that the stepwise extraction is not conducive to NOx pollution control of coal combustion, especially HCl-soluble minerals are an important factor to control the formation of gas-N. The removal of HCl-soluble minerals leads to the transformation of a large amount of char-N into gas-N, which will cause more NOx emissions.
