Aromatic Hydrocarbon External Controls Of Road Works On The Territory Of The Eurometropolis In Strasbourg
Key statement: A rubber material is described, modified with a barrier material in the form of a copolymer which can be produced via ring-opening metathesis polymerization of a) at least one olefin monomer selected from the group consisting of monocyclic olefin monomers having one or two endocyclic C--C double bonds and bicyclic olefin monomers having one endocyclic C--C double bond and b) at least one polycyclic
olefin monomer having at least two C--C double bonds.
Prenatal exposure to polycyclic
aromatic hydrocarbons (PAHs) has previously been associated with higher incidence of depression, anxiety, and attention problems among highly exposed children.
The most toxic parts are the small aromatic solvents and the complex sheets of cyclic structures called polycyclic
In a cohort study of 432 nonsmoking pregnant women who gave birth at term, consumption of grilled meat (a major source of polycyclic
aromatic hydrocarbons [PAH]) was associated with a significant reduction in birth weight of 106 g, after adjustment for prenatal exposure to airborne PAH and other potential confounding variables.
aromatic hydrocarbons have already been linked to lower IQs, anxiety, depression and attention deficit disorder.
aromatic hydrocarbons are known carcinogens and have been linked to developmental problems.
Unidentified infrared emissions in interstellar space are not caused by polycyclic
aromatic hydrocarbons, new research indicates.
Firefighters working in the rubble of the World Trade Center were exposed to potentially hazardous aerosolized dust consisting of pulverized cement, glass fibers, asbestos, lead, polycyclic
aromatic hydrocarbons, polychlorinated biphenyls, and polychlorinated furans and dioxins produced as combustion byproducts from the collapsed and burning buildings.
aromatic hydrocarbons (PAHs) are a class of multiphasic organic compounds composed of two or more fused aromatic rings.
As a class of well known toxic compounds originating from incomplete combustion [1, 2, 3], polycyclic
aromatic hydrocarbons (PAHs), normal hydrocarbons (NHs) are among the most important environmental contaminants in China  as well as all over the world.
9, 2010 /PRNewswire-USNewswire/ -- More than two years after Austin, TX banned refined tar sealants, there has been no discernable change in either the amount or sources of polycyclic
aromatic hydrocarbons in sediment in Austin's waterways.
