Assessment of the State of Water, Soil and Bottom Sediments of the Territory Adjacent to the Former Ash-disposal Area

Abstract

A comprehensive chemicalanalytical investigation of the state of water, soil, bottom sediments, as well as technogenic soils of the former ash-disposal area in the water-shed area of the Red River in Khabarovsk was carried out. River water exceeds the MAC of soluble chemicals in terms of the content of suspended solids, phenols, oil products, as well as some heavy metals (iron, manganese, copper, nickel and zinc). Widespread contamination of bottom sediments and soil of the ash-disposal area with arsenic was revealed. The background rate of oil products was exceeded by 5.6 times in the soil of the water protection zone of the river. The conclusion was made about the genetic similarity in bottom sediments and soils which is due to the long-term impact of a complex of anthropogenic factors on the water-shed area of the Red River.
