CONSERVING OF THE RESOURCES
Soil pollution: pollutants, causes and effects
Soil is a complex heterogeneous system composed of solid, liquid and gaseous matrix, which is a key factor for terrestrial ecosystems. As an open system, it is a source or sink of many substances, including pollutants. Pollutants in soils can be of natural or anthropogenic origin, which are generally divided into two main groups: organic and inorganic pollutants. The report is prepared on the basis of scientific literature and is entirely aimed at clarifying the sources, impact and effects of persistent organic compounds. For this purpose, 32 scientific articles available in ResearchGate, Scholar and ScienceDirect were studied. Attention is focused on them, as they are considered a global environmental problem due to their persistence, potential for bioaccumulation, toxicity, carcinogenic and mutagenic potential.
