CHANGES IN THE POLLUTION OF LODZ VOIVODSHIP RAINWATER AS A RESULT OF CHANGES IN POLLUTANT IMMISSIONS

Abstract

Increasing urbanization rates, particularly in cities, cause an increase in pollutant emissions into the
environment. Immission of pollutants is the amount of particulate or gaseous pollutants that is received by the
environment. Natural precipitation, i.e. rainwater, is polluted during the contact with air. As a result of
atmospheric precipitation groundwater and soil become polluted. The pollutants also penetrate surface water,
causing further contamination. In rainwater that goes to the sewage system, there are pollutants such as
hydrocarbons, heavy metals, slurries, plant protection products and many more. This is largely dependent on
the type of management of the catchment, its sanitary condition, and the time and intensity of precipitation.
Another important factor is the composition of pollutants emitted into the atmospheric air in each area. The
work shows changes in the pollution of rainwater in Lodz Voivodship in the years 2010-2016 and presents
analysis of the data collected by the Regional Inspectorate for Environmental Protection. The analysis shows
that the state of rainwater is steadily deteriorating which is directly related to air quality.
