It said that while there was an "occasional presence" of dioxins, polyaromatic
hydrocarbons, and volatile compounds, the health risks were "low due to the infrequent detections of these chemicals.
Once oil is found, one of the waste products of the pumping process is so-called produced water, which often contains heavy metals, low-level radioactivity, traces of drilling fluid additives and polyaromatic
But of greater concern is the release of polyaromatic
hydrocarbons (PAHs) such as benzopyrene, which are known carcinogens.
hydrocarbons (PAHs) and heterocyclic amines (HCAs) are carcinogens in the food supply, but as food items not implicated in the aetiology of colorectal cancer may actually be greater contributors to the total dietary intake of these compounds than red meat, they do not provide a plausible basis for implicating red meat in carcinogenesis.
Incense burning produces a great deal of particulate matter and releases many possible carcinogens including polyaromatic
hydrocarbons, carbonyls, and benzene.
In 2004, the DEQ determined that the mulch contains toxins such as arsenic and polyaromatic
hydrocarbons in concentrations higher than those considered safe for soils at residential and commercial settings.
This finding was in line with findings of other studies, which have reported that long-term exposure to polyaromatic
hydrocarbons in workers or high concentrations of n-pentane resulted in significant observed immunosuppression (Szczeklik et al.
He believes carcinogens such as polyaromatic
hydrocarbons and other impurities from the spill have entered the sea, causing an estimated $200 million in damages to ecosystems, the seafood industry and tourism.
In the present investigation bio-degradation of anthracene, a polyaromatic
hydrocarbon, from its simulated mixture in methanol, has been studied using a monoculture strain, (Acinetobacter sp.
Although employing carbon dots would avoid the use of toxic metal ions, Strano notes, it's not yet clear whether the carbon nanoparticles are graphite, which is stable, or an amorphous form of carbon, which might contain carcinogenic polyaromatic
