Quoted: A new study investigated the association between short-term exposure to ambient fine particulate matter and the risk of stroke. Researchers found that recent exposure to fine particulate matter may increase the risk of ischemic cerebrovascular events.

The Toxicology and Environmental Health Information Program (TEHIP) evolved from the Toxicology Information Program (TIP) that was established in 1967 at the National Library of Medicine (NLM) in response to recommendations made in the 1966 report "Handling of Toxicological Information," prepared by the President's Science Advisory Committee. The TIP objectives were to: (1) create automated toxicology data banks, and (2) provide toxicology information and data services. In the mid-1990's, the mission of TIP was expanded to include environmental health. TEHIP, by creating, organizing, and disseminating toxicology and environmental health information, now serves as a premier information portal for resources in these subject areas.

Quoted: PCB health effects can take many forms, affecting several systems in the body.

Quoted: Dopamine levels are decreased by PCB chemical exposure, as shown by multiple research studies. Parkinsons Disease may result.

A pesticide is a substance or mixture of substances used for preventing, controlling, or lessening the damage caused by a pest.[1] A pesticide may be a chemical substance, biological agent (such as a virus or bacteria), antimicrobial, disinfectant or device used against any pest. Pests include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms) and microbes that compete with humans for food, destroy property, spread or are a vector for disease or cause a nuisance. Although there are benefits to the use of pesticides, there are also drawbacks, such as potential toxicity to humans and other animals.

Polychlorinated biphenyls (PCBs) are a class of organic compounds with 1 to 10 chlorine atoms attached to biphenyl which is a molecule composed of two benzene rings each containing six carbon atoms. The chemical formula for all PCBs is C12H10-xClx.

PCBs were used as coolants and insulating fluids for transformers and capacitors, stabilizing additives in flexible PVC coatings of electrical wiring and electronic components, pesticide extenders, cutting oils, flame retardants, hydraulic fluids, sealants (used in caulking, etc), adhesives, wood floor finishes,[1] paints, de-dusting agents, and in carbonless copy paper.[2]

PCB production was banned in the 1970s due to the high toxicity of most PCB congeners and mixtures. PCBs are classified as persistent organic pollutants which bioaccumulate in animals.

Climate change: we have the power
There are pale greens and dark greens. Often they don’t see eye to eye. But there is no shortage of technologies to tackle global warming. We listen to the visionaries of change
