We found, in both cases and controls, occupational exposure as main cause of
toxicants exposure (PD: occupational = 77.3%, environmental = 22.7%; controls: occupational 81.6%; environmental = 18.4%; p = n.s.).
Toxic substances may be systemic
toxicants or organ
toxicants.
They fight it with various
toxicants, including chlorine and potassium salts.
Creosote was the only
toxicant that affected the frequencies of hemocyte subpopulations in tunicates exposed to
toxicants in aquaria [ILLUSTRATION FOR FIGURE 5 OMITTED].
Gold nanoparticles create red color after combining with the
toxicant and the color is visible by naked eye too.
Several decades have been spent researching the nature of tobacco smoke, identifying key
toxicants and developing technologies to reduce the levels of some
toxicants in smoke.
Although pathogens are known to modify the effects of
toxicants, U.S.
However, DEHP in neonates is a special concern because "it is a reproductive and developmental
toxicant in laboratory animals," says study author Russ Hauser of the Harvard School of Public Health in Boston.
Previous research indicates that many
toxicants can increase cells' oxidative status, but questions remain as to how this shared ability relates to
toxicant function.
They rank each
toxicant in terms of toxicity, exposure, and risk on a scale of 0 to 100, and this helps put the relative risk of this diverse group of agents in perspective.
Last year, an American Academy of Pediatrics report designated mercury a major environmental
toxicant that "should not be present in the home or other environments of children: It explicitly identified old fever thermometers as a source.
The likelihood of exposure to environmental
toxicants increases in most economically disadvantaged communities and is associated with an excess disease burden in these communities."
