Evaluation of Polycyclic Aromatic Hydrocarbons Content of Soil in Areas Heavily Industrialised

摘要

This research is part of a broad study to monitor the content of polycyclic aromatic hydrocarbons in the environment and then the chain of traceability, animal fodder, meat and meat preparations. This study aims to identify the possible accumulatipn of these contaminants in the soil in surrounding areas of the city of Targoviste, which is highly industrialized. These lands are planted with cereals which are used in animal feed. The effects of the polycyclic aromatic hydrocarbons on the human health, inclusively through the trophy chain and on the environment as a whole are harmful through their concentrations in the ambient air and through their depositions; it should be taken into account the accumulation of these substances in soils and the protection of underground waters. Measurements were made using modern methodology, which allowed detection of even low PAH in the samples analyzed. For this purpose PAHs were dosed by high-performance liquid chromatography (HPLC) of soil samples collected from areas surrounding the city. Soil samples were collected from surface and depth. Fourteen PAHs were determined. Several of them are known to be potential human carcinogens including benzo[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[a]pyrene and benzo[ghi]perylene. They have recorded values below accepted European norms in force.
