Polycyclic aromatic hydrocarbons (PAHs), as the main components of petroleum (PHCs), are carcinogenic organic pollutants that occur widely in atmospheric environment with increasing concentration. Moreover, PAHs widespread all over world due to their high volatility and long-range transport potential. The monitoring is often limited by working conditions, especially around oil field operation a...

Background: Yearly the Shanxi coal chemical industry extracts many coal resources, producing at the same time many polycyclic aromatic hydrocarbons (PAHs) that are emitted as by-products of coal incomplete combustion. Methods: Sixty-six soil samples collected from 0 to 100 cm vertical sections of three different agricultural (AS), roadside (RS) and park (PS) functional soils around a chemical p...

The floodplains and seacoasts of southern Russia are characterized by urbanization, developed agriculture, rapidly developing industries. Anthropogenic activity leads to the long-term release pollutants into environment, which threatens stability ecosystems public health. study aimed assess ecological human health risks posed potentially toxic elements (PTEs) polycyclic aromatic hydrocarbons (P...

Polycyclic aromatic hydrocarbons (PAHs) settled in floor dust play an important role in human health. Although many studies investigated occupational exposure to PAHs, no attempts have been made to report PAHs concentrations as well as their health risk assessment inside an educational building in Jordan. Therefore, the main objective of this study is to report the PAHs concentrations in floor ...

Present study was undertaken to examine the extent of Polycyclic Aromatic Hydrocarbons (PAHs) contamination in neighbourhood lithospheric environment of landfill site situated in eastern outer edge of Kolkata metropolitan city in West Bengal, India, along with its sources identification, spatial distribution and probabilistic cancer risks to residents. The collection and analytical tests were p...

The carcinogenic polycyclic aromatic hydrocarbons (PAHs) are active primarily at the site of entry to the body. Lung cancer following inhalation of PAH-containing aerosols such as tobacco smoke is one likely example. A suggested mechanism for this site preference is a slow passage of the highly lipophilic PAHs through the thicker epithelia of the conducting airways, accompanied by substantial l...

Informal e-waste recycling activities results in serious environmental pollution of PAHs. We evaluated the body burden of 16 PAH congeners and potential health risks for children. A total of 167 children from exposed and reference area entered this study. Child blood samples were collected; height, weight, head and chest circumferences were measured. Blood PAH and lead concentrations were deter...

Polycyclic aromatic hydrocarbons (PAHs) in sediment cores from Phayao Lake were investigated terms of their concentration, distribution, and potential effects on the environment human health. The concentration ?16PAHs ranged 77.6 to 1251.1 ng g-1. Additionally, low molecular weight PAHs (two or three fused rings) dominant, indicating that main source is incomplete combustion organic sources. to...

An integrated risk assessment study has been performed in an area within 5 km from a landfill that accepts non hazardous waste. The risk assessment was based on measured emissions and maximum chronic population exposure, for both children and adults, to contaminated air, some foods and soil. The toxic effects assessed were limited to the main known carcinogenic compounds emitted from landfills ...

BACKGROUND Polycyclic aromatic hydrocarbons (PAHs) are abundant and widespread environmental chemicals. They are produced naturally and through man-made processes, and they are common in organic media, including petroleum. Several PAHs are toxic, and a subset exhibit carcinogenic activity. PAHs represent a range of chemical structures based on two or more benzene rings and, depending on their s...
