Remember that if anyone's going to suffer from the air pollution they create, you're first in line. The British government refused to acknowledge the problem and that was partly why the UK became known as "the dirty man of Europe" in the s and s. Step back a century or two and the cause of most air pollution was easy to identify: filthy factories, powering the Industrial Revolution.
Certain persistent air toxics may contribute not only to atmospheric pollution but to water pollution.
The lung that had been breathing clean air was pink and fleshy, while the organ from Delhi was covered in a black substance that closely resembled tar. When the weather turns cold, the city's poor huddle together in slums and along busy roads, warming themselves around small wood or trash fires.
Lead and heavy metals: Lead and other toxic "heavy metals" can be spread into the air either as toxic compounds or as aerosols when solids or liquids are dispersed through gases and carried through the air by them in such things as exhaust fumes and the fly ash contaminated waste dust from incinerator smokestacks.
Many once-polluted cities now have relatively clean air and water, largely thanks to anti-pollution laws introduced during the midth century. Volatile organic compounds VOCs : These carbon-based organic chemicals evaporate easily at ordinary temperatures and pressures, so they readily become gases.
Picture courtesy of U. For example, changes in intensity and distribution of rainfall in India and China have been linked to particulate matter pollution. Importantly, some particulate matter can also have a cooling effect by blocking solar radiation, but there will always be a health benefit from reducing particular matter.
If you have a gas or oil-fired boiler or a coal- or wood- fired stove and it's not properly ventilated, it will generate dangerous and toxic but colorless and odorless carbon monoxide gas. At one point on the main route to Gurgaon, which is known for producing legendary traffic jams, the road briefly widens to 15 lanes.
We need to look at three systems — food, energy and waste and how we can transform them into healthy fortunes.
