Organic Compounds in Bottom Sediments under Conditions of Coastal Urbanization (a Case Study of Kazach’ya Bay of the Black Sea)

Аннотация

Data on the hydrocarbon composition of bottom sediments from a water area adjacent to an area with massive cottage construction (Kazach’ya Bay, coast of Sevastopol, the Black Sea) are presented. Analysis of bottom sediments performed in the summer 2015 provided values for the pH, Eh, natural humidity, and content of chloroform-extractable compounds, petroleum hydrocarbons, petrochemicals, polyaromatic hydrocarbons, and n-paraffins. Sites with unfavorable and moderately unsatisfactory ecological state were identified. The effect of urban development on the coast on the deterioration of bottom sediments was demonstrated.
