The contaminants in wastewater include not only heavy metals but also many organic compounds such as
PAHs (Hao, Wang, & Li, 2010; Zhang et al.
The total concentrations of 16
PAHs varied from 152.
It found some
PAHs in coal tar sealcoats that were 30 times more toxic than one of the most common
PAH compounds that was studied previously in these products by the U.
At outdoor points, the most common sources of
PAHs was both from petrol and diesel combusted vehicles, and diesel fumes from generator sets," the study by S.
According to the National Cancer Institute,
PAHs are formed when the juices and fitt from grilled meats drip onto the fire or heat source, causing flames.
Pyrogenic and petrogenic sources are two major origins of anthropogenic
PAHs in the environment.
The airborne emissions of
PAHs (2003) have been shown to be comparable to
PAHs concentrations in the urban air, and the dioxine emissions (2007) have been close to the detection limit, 4 pg/[m.
These
PAHs form metabolites in the body that can directly destroy the normal structure of DNA and subsequently cause the formation of abnormal proteins and cancerous tumors.
To test the idea that
PAHs were responsible, we measured and computed
PAH spectra under astronomical conditions, creating the world's largest collection of
PAH spectra.
We successfully analyzed two dust samples for
PAHs in 201 homes and successfully analyzed only the second dust sample for
PAHs in three homes.
The team also found that kids exposed to a lot of
PAHs made excess amounts of an antibody called immunoglobulin E, or IgE.
Four
PAHs (naphthalene, acenaphthene, phenanthrene and anthracene) were extracted by Soxhlet extraction and direct ultrasonic technique from the agricultural and urban soil samples of refinery adjacent area in Rawalpindi district of Pakistan.
