ANALYSIS OF POLLUTED PLACES: CASE OF LAND DEGRADATION IN LATVIA

Abstract

The aim of the article is to analyse and evaluate the information on polluted and potentially polluted places registered in the Register of polluted and potentially polluted places in Latvia. Under the influence of various natural conditions and economic activities land and soil degradation processes are observed, which has led to formation of degraded territories. Degraded territory is a territory with destroyed or damaged upper layer of ground or an abandoned territory of construction, extraction of mineral resources, economic or military activities, which in result of economic or other activity or inaction has so far destroyed, that is impossible to use it properly without special restoration measures. One of the factors that can be used to assess land degradation and determine the type of land degradation is pollution. In accordance with the Law “On pollution” in Latvia have been established procedures for identification of polluted places and developed criteria which are used for assessment of risk level. On this basis the Centre for Environment, Geology and Meteorology of Latvia has established and maintains the Register of polluted and potentially polluted places. The polluted place is soil, subsoil, water, sludge, as well as buildings, factories or other objects containing pollutants. Potentially polluted places can be listed according to unverified information. In 2017 in Latvia 351 polluted and 2648 potentially polluted places were listed and registered. The largest concentration of polluted places is located in Riga, which is largest industrial centre in Latvia.
