The significance of polycyclic aromatic hydrocarbons as environmental carcinogens
In vivo and in vitro experiments have shown that various polycyclic aromatic hydrocarbons are potent mutagens and/or carcinogens. Occupational and epidemiological studies suggest that they also have to be considered as hazards for humans. Due to their formation during all kind of incomplete combustions they are widespread to the environment. Balancing the carcinogenic effect of environmentally ...
متن کاملPolycyclic Aromatic Hydrocarbons as Environmental Pollutants: A review
Polycyclic aromatic hydrocarbons (PAHs) represent a group of persisting and prevalent environmental pollutants that are harmful to the environment and humans due to their toxic, mutagenic and carcinogenic potential. The emission of PAHs into the environment has increased with the increase in demand for petroleum products. The incomplete combustion of organic products such as coal, fuel oil, fir...
متن کاملBiodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملTransport of Polycyclic Aromatic Hydrocarbons in a Calcareous Wetland Soil
Knowledge of transport and degradation of polycyclic aromatic hydrocarbons (PAHs) is important in assessing PAH contamination of soils and water resources. The transport of naphthalene, anthracene, pyrene and phenanthrene was determined in a contaminated calcareous soil obtained from the Shadegan wetland (Khozestan, Iran) considering a column study in laboratory conditions. The PAHs were added ...
متن کاملDeuterium enrichment of polycyclic aromatic hydrocarbons by photochemically induced exchange with deuterium-rich cosmic ices.
The polycyclic aromatic hydrocarbon (PAH) coronene (C24H12) frozen in D2O ice in a ratio of less than 1 part in 500 rapidly exchanges its hydrogen atoms with the deuterium in the ice at interstellar temperatures and pressures when exposed to ultraviolet radiation. Exchange occurs via three different chemical processes: D atom addition, D atom exchange at oxidized edge sites, and D atom exchange...
