PAH Exposure
A 140 volume 117 | number 4 | April 2009 • Environmental Health Perspectives PAH Exposure doi:10.1289/ehp.0800445 We were very interested to read the article by Choi et al. (2008). The difference between maternal exposure and our own data on actual concentrations of poly cyclic aromatic hydro carbons (PAHs) in the human male fetal liver (Fowler et al. 2008) was striking. Eight of the PAH exposu...
متن کاملCHILDREN’S HEALTH: Methylation Links Prenatal PAH Exposure to Asthma
Phosphorylation, in which phosphate groups attach to proteins or small molecules, is among the cell's primary means of controlling protein activity. It regulates nearly every aspect of cell life, including cell metabolism , proliferation, viability, differentiation, apoptosis, and transmission of hormone and growth factor signals. Protein kinases are the enzymes that catalyze this myriad of mol...
متن کاملPlankton stress responses from PAH exposure and nutrient enrichment
The hypothesis that the nature and force of PAH stress responses from plankton systems are coupled to the nutrient status of that system was tested in a mesocosm experiment. Four treatments were applied consisting of control (Cn), pyrene exposed (PYl. nutrient spiked (Nul. and nutrient spiked and pyrene exposed (NuPy) groups in replicate bags (n = 3) representing plankton communities including ...
متن کاملComparative modeling approaches for personal exposure to particle-associated PAH.
Several models for simulation of personal exposure (PE) to particle-associated polycyclic aromatic hydrocarbons (PAH) have been developed and tested. The modeling approaches include linear regression models (Model 1), time activity weighted models (Models 2 and 3), a hybrid model (Model 4), a univariate linear model (Model 5), and machine learning technique models (Model 6 and 7). The hybrid mo...
متن کاملPAH-DNA Adducts in Cord Blood by Plasma Antioxidants Modulation of the Effect of Prenatal PAH Exposure on
The fetus is more susceptible than the adult to the effects of certain carcinogens, such as polycyclic aromatic hydrocarbons (PAH). Nutritional factors, including antioxidants, have been shown to have a protective effect on carcinogen-DNA adducts and cancer risk in adults. We investigated whether the effect of prenatal airborne PAH exposure, measured by personal air monitoring during pregnancy,...
