Polycyclic Aromatic Hydrocarbons Sources

Polycyclic aromatic hydrocarbons sources

Exposures are highest near industrial or urban sites, such as aluminum smelters and oil sands mines, polycyclic aromatic hydrocarbons sources near natural sources such as forest fires. This review assesses the exposure and toxicity of PACs to wildlife, with a focus on the Canadian environment. Most published field studies measured PAC concentrations in tissues of invertebrates, fish, and birds, with fewer studies of amphibians and mammals. In general, PAC concentrations measured in Canadian wildlife tissues were under the benzo[a]pyrene BaP guideline for human consumption.

Health effects of PAC exposure include embryotoxicity, deformities, cardiotoxicity, DNA damage, changes to DNA methylation, oxidative stress, endocrine disruption, and impaired reproduction. Much of the toxicity of PACs can be attributed to their bioavailability, and the extent to which certain PACs are transformed into more toxic metabolites by cytochrome P enzymes. As most mechanistic studies are limited to individual polycyclic polycyclic aromatic hydrocarbons sources hydrocarbons https://modernalternativemama.com/wp-content/custom/argumentative-essay/white-collar-criminality-edwin-sutherland-summary.phpparticularly BaP, research on other PACs and PAC-containing complex mixtures is required to understand the environmental significance of PAC exposure and toxicity.

Additional work on responses to PACs in amphibians, reptiles, and semi-aquatic mammals, and development of molecular markers for early detection of biological responses to PACs would provide a stronger biological and ecological justification for regulating PAC emissions to protect Canadian wildlife.]

Show more Prenatal exposure to fine particles and polycyclic aromatic hydrocarbons and birth outcomes : a two-pollutant approach by multiple linear regression, controlling for potential confounders parity, maternal education, pre-pregnancy weight, weight gain during pregnancy, sex of infant, gestational age, and season of birth. We tested season of birth for confounding because of its association with exposure and potential association with fetal growth. Season of birth was introduced in the regression models as a dummy variable, with summer defined as the refer- ence level. Because the distribution of the air pollutants was skewed, the PM 2.
