Enzymatic Activity and Content of Polycyclic Aromatic Hydrocarbons (PAHs) in Soils under Low-Stack Emission in Lublin

Abstract

Soils from the Lublin area exposed to low-stack emission from home heating and transport were investigated. Changes in soil enzymatic activity and polycyclic aromatic hydrocarbon s (PAHs) content were analysed. Soil samples were collected in July and November 2016 and January 2017. Results of the study show that enzymatic activity and PAHs content depended on types of buildings, study period (intensification of pollutant emission from household heating), traffic volume and atmospheric air movement. Low enzymatic activities and high PAHs contents in the soils were observed in the autumn-winter period in the areas with dense single-family housing and located in the vicinity of streets with intense road traffic.
