BACKGROUND Polycyclic aromatic hydrocarbons (PAHs) are known carcinogens and suspected endocrine disruptors. Prenatal exposure to PAHs has been associated with obesity in early childhood. OBJECTIVE We examined the association of urinary PAH metabolites with adiposity outcomes [body mass index (BMI) z-score, waist circumference (WC), and rate of obesity] in children and adolescents. METHODS ...

Polycyclic aromatic hydrocarbons and heavy metal (Pb, Cd, Cu, Zn, Hg, Fe, Co, Cr, Mo) contents were established in soil and plant samples collected in different areas of the railway junction Iława Główna, Poland. Soil and plant samples were collected in four functional parts of the junction, i.e. the loading ramp, main track within platform area, rolling stock cleaning bay and the railway sidin...

The Deepwater Horizon (DWH) blowout resulted in oil transport, including polycyclic aromatic hydrocarbons (PAHs) to the Gulf of Mexico shoreline. The microbial communities of these shorelines are thought to be responsible for the intrinsic degradation of PAHs. To investigate the Gulf Coast beach microbial community response to hydrocarbon exposure, we examined the functional gene diversity, bac...

polycyclic aromatic hydrocarbons (pahs) which are toxic pollutants are released by various sources of urban combustion. ahvaz in iran with around a million population and the industrial and oil centers, has encountered air quality problems. samples of dibenzo (a,h) antheracen were collected from six stations in ahvaz particle and gas phase in summer 2010. dibenzo(a,h) antheracen were collected ...

In recent years the scientific community showed an increasing interest for implementing new, rapid, sensitive and cheaper detection methods that are far better than classical of quantification polycyclic aromatic hydrocarbons (PAHs), especially with progress in synthesis nanomaterials can be successfully used design electrochemical sensors. This review aims to discuss latest research activities...

Nitro-polycyclic aromatic hydrocarbons (nitro-PAHs) are a class of genotoxic environmental contaminants. We have long been interested in determining the mechanisms by which nitro-PAHs induce genotoxicity. Although the metabolic activation of nitro-PAHs leading to toxicological activities has been well studied, the photo-induced activation of nitro-PAHs has seldom been reported. In this paper, w...

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants, and have been reported to be a risk factor for human neural tube defects (NTDs). We investigated the relationship between PAH concentrations in maternal serum and NTD risk in offspring using a case-control study design, and explored the link between PAH concentrations to household energy usage characteristics and l...

Polycyclic aromatic hydrocarbons (PAHs) are very hazardous compounds and, owing to their lipophilicity, they can easily cross biological membranes and accumulate inside organisms, causing damage to the genetic material. The scientific interest in PAHs is related to their demonstrated or supposed genotoxicity (cancer-causing characteristics of B[alpha]Py and dB[alpha, h] first suspected in the 1...
