  • The pollutants we are talking about are known as polyaromatic hydrocarbons and will not accumulate to a high concentration to cause severe damage.

  • In an article published in the European Respiratory Journal, the scientists said cannabis could be expected to harm the airways more than tobacco as its smoke contained twice the level of carcinogens, such as polyaromatic hydrocarbons, compared with tobacco cigarettes.

  • “So for us, an important goal of the experiment is also to see about the formation of polyaromatic hydrocarbons,” Ehrenfreund told me.

  • For example, aquatic organisms that have assimilated UV-B absorbing polyaromatic hydrocarbons have shown phototoxic effects when exposed to UV-B radiation.

    Climate change, interactive changes and stresses in the Arctic

  • Most of those hydrocarbons aromatic and polyaromatic get converted into nice, clean carbon dioxide in American automobiles, mixed right in with our gasoline.

  • Many types of pollutant have been identified in arctic biota and the arctic environment, including polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and heavy metals [98].

    Potential impacts of direct mechanisms of climate change on human health in the Arctic

  • The main public health impact is caused by small airborne particles (particulate matter), their toxic constituents, such as heavy metals and polyaromatic hydrocarbons, as well as by tropospheric ozone.

  • There are persistent organic pollutants (POPs) such as DDT, brominated flame retardants and polyaromatic hydrocarbons heavy metals, such as lead, cadmium and mercury, and oxides of nitrogen and sulphur.

  • At this point we have discussed the pre-Industrial Revolution developments in toxicology, that were primarily devoted to the study of such naturally-occurring toxicants as the polyaromatic compounds contained in soot and heavy metals, and such toxins as botulinum toxin produced by the bacterium Clostridum botulinus.

    History of toxicology

  • For example, caffeine, certain pesticides, some of the carcinogens found in cigarettes, and the polyaromatic amines found in charbroiled beef are all detoxified by the activity of one cytochrome known as CYP1A2.
