Environmental problems of ferrous and non-ferrous metallurgy in the world

Metallurgy is the largest industry, but, like other areas of the economy, it has a negative impact on the environment. Over the years, this influence leads to pollution of water, air, soil, which entails climate change.

Air emissions

The key problem of metallurgy is that harmful chemical elements and compounds get into the air. They are released during the combustion of fuel and processing of raw materials. Depending on the specifics of production, the following pollutants enter the atmosphere:

  • carbon dioxide;
  • aluminum;
  • arsenic;
  • hydrogen sulfide;
  • mercury;
  • antimony;
  • sulfur;
  • tin;
  • nitrogen;
  • lead, etc.
  • Experts note that every year, due to the work of metallurgical plants, at least 100 million. tons of sulfur dioxide. When it enters the atmosphere, it subsequently falls to the ground in the form of acid rain, which pollutes everything around: trees, houses, streets, soil, fields, rivers, seas and lakes.

    Industrial waste

    The actual problem of metallurgy is the pollution of water bodies by industrial effluents. The fact is that water resources are used at various stages of metallurgical production. During these processes, water is saturated with phenols and acids, coarse impurities and cyanides, arsenic and cresol. Before discharging such effluents into water bodies, they are rarely cleaned, so all this “cocktail” of chemical precipitation from metallurgy is washed off in the waters of cities. After that, water saturated with these compounds, not only can not be drunk, but also used for domestic purposes.

    Consequences of pollution of the biosphere

    Pollution of the environment by the metallurgical industry, first of all, leads to a deterioration in the health of the population. Worst of all is the condition of those people who work in such enterprises. They develop chronic diseases that often lead to disability and death. Also, all people living near factories eventually get serious illnesses, as they are forced to breathe dirty air and drink poor quality water, and pesticides, heavy metals and nitrates enter the body.

    To reduce the level of negative impact of metallurgy on the environment, it is necessary to develop and use new technologies that are safe for the environment. Unfortunately, not all enterprises use cleaning filters and facilities, although this is mandatory in the activities of each metallurgical enterprise.
