Influence of hydroclimatic risk factors on the river pollution phenomenon

Abstract

The paper presents an analysis of the river pollution phenomena in the Trotuş River Basin. The Trotuş River area has been affected by multiple floods over the past 28 years (significant in 2004, 2005, 2011 and 2016). The most important categories of pollutant pressures in the Trotuş Hydrographic Basin are punctual, diffuse and hydromorphological. The most significant point sources of pollution in the river basin are of domestic, industrial and agricultural type. The pollutants that affected the watercourses in the Trotuş catchment area during the study period were petroleum products (51.2%) and organic substances (21.4%). The remaining 27.4% of pollutants are ammonium, ammonia, hydrogen sulphide, heavy metals, cyanide, urea, detergents, ash, phosphorus, etc.
