There are many substances released into the environment by careless individuals or industry that harm both humans and the environment. These are pollutants.
Carbon monoxide (CO) binds to the body’s red blood cells, preventing the transport of oxygen. As a result of a tragic incident that cost two children their lives, there is a push to put CO detectors in homes. It is refered to as a silent killer due the fact it is odourless and invisible.
Oxides of nitrogen (NOx) can cause emphysema and other respiratory illnesses as well as cell damage. Nitrogen dioxide in particular has a horrid smell to it.
While in the stratosphere it provides protection against UV radiation, ozone has nasty implications for human health. It is a respiratory irritant and involved in the formation of photochemical smog.
Sulphur dioxide is another foul smelling gas that can cause chronic bronchitis.
Mercury, lead, cadmium and other heavy metals can contaminate food chains via bioaccumulation. Mercury has caused significant problems in Japan and cadmium was the cause of all the illnesses in the film ‘Erin Brokovich’.
Carbon dioxide is involved in photosynthesis and is a crucial part of life as we know it. It is NOT A POLLUTANT!
Why will the politicians, the media not face up to this simple fact? No matter what people think of it as a greenhouse gas, we wouldn’t be alive without it. Yes, I know it is just a gas but we would not be alive without it, so show some respect!
