Contamination of Tea and Tea Infusion with Polycyclic Aromatic Hydrocarbons
The aim of this work was to validate the method of determination of polycyclic aromatic hydrocarbons (PAHs), i.e., benzo(a)pyrene and sum of benzo(a)pyrene, benz(a)anthracene, benzo(b)fluoranthene and chrysene in different types of tea, as well as to assess the transfer of these contaminants from tea to tea infusion. The research materials were popular types of black, green, red and white tea. ...
متن کاملSimultaneous Monitoring Method of Polycyclic Aromatic Hydrocarbons
intentionally manufactured or synthesized, as well as dioxins; however, they exist in fossil fuels, such as petroleum and coal. They are organic pollutants produced unintentionally by the combustion of organic compounds, like fossil fuels and waste. Especially, PAHs are formed during incomplete combustion; some PAHs, such as benzo(a)pyrene, have high carcinogenicity and mutagenicity for humans ...
متن کاملContamination of rivers in Tianjin, China by polycyclic aromatic hydrocarbons.
Tianjin urban/industrial complex is highly polluted by some persistent organic pollutants. In this study, the levels of 16 priority polycyclic aromatic hydrocarbons (PAHs) were tested in sediment, water, and suspended particulate matter (SPM) samples in 10 rivers in Tianjin. The total concentration of 16 PAHs varied from 0.787 to 1943 microg/g dry weight in sediment, from 45.81 to 1272 ng/L in ...
متن کاملMonitoring of environmental exposure to polycyclic aromatic hydrocarbons: a review
Polycyclic aromatic hydrocarbons (PAHs) are a large group of organic compounds with two or more fused aromatic rings. They have a relatively low solubility in water, but are highly lipophilic. Most of the PAHs with low vapour pressure in the air are adsorbed on particles. When dissolved in water or adsorbed on particulate matter, PAHs can undergo photodecomposition when exposed to ultraviolet l...
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...
