The Effects of Air Pollution


The effects of air pollution are wide and aren’t far fetched. People, animals, plant life and even inert materials can and are affected by this demise. History tells that in October 1948, a stagnant fog heavy with pollution blanketed a small industrial town of Donora, Pennsylvania.The fog lasted for four days, and by the time it had cleared, six thousand of the town’s fourteen thousand people were sick and twenty had died. Four years later, a killer smog in London had caused an estimated four thousand deaths. In 1970, however, more than eight thousand people in Tokyo, Japan needed medical treatment for eye, nose, and throat irritations when heavy white smog containing sulfurous acid covered the city for five days.

The most serious and immediate menace of air pollution lies in its physical effects on human beings even though it is quite difficult to access the long term health effects of air pollution. Yet there’s no doubt that ailments such as emphysema, chronic bronchitis, bronchial asthma and other respiratory diseases are aggravated by regular exposure to present high levels of city or urban air pollution.
Also, air pollution abrade, corrode, tarnish; soil, erode, crack, weaken and discolor materials of many varieties. For example, steel corrodes two to four times faster in sulphuric laden air.

Air pollutants kill and injure plant life and cover. In times past, trees and shrubs in Tokyo, Japan were seen to die in the gardens of the Imperial Palace. In northern Bohemia, Central Europe, polluted air from the brown-coal belt caused blight in agricultural areas and heavily damaged forests.
In fact, the effects on vegetation are often a clue to the existence of air pollutants which are not noticeable in other forms.

Carbon IV Oxide, hydrocarbons, sulphuric compounds, metals, acids and ozone are serious threats to most vegetation. Plants which are exposed to these pollutants absorb them through their leaves. And these leaves develop holes; they become discolored or wilt, and eventually they may perish or die. This can also lead to the death of the entire plant.

Smoke and fumes from factories especially smelters have caused the death of entire forests. In the Los Angeles area, the death of many trees have been attributed to carbon emissions from motor vehicles or automobiles. Some other undesirable effects of pollution include the damage done to buildings and materials. Sulphuric pollution actually causes steel, zinc and building stone to corrode. Ozone damages rubber and textiles, and also discolors dyed materials.

#Recycling in Developing #Africa

Every day around the world, people throw away things when they are no longer needed or in use. And every day people discard solid #wastes and lots of paper into garbage cans and bags for collectors, or worst still we litter our immediate environment with these wastes. Sometimes, we discard an old shirt or blouse or worn out automobile tyres.   And once in a long while, you discard something really big, perhaps an old refrigerator or a very old car.   Also, after lunch we throw away cans after emptying the contents of a soft drink or fruit juice, and we discard empty bottles of milk after breakfast most mornings. If we were to weigh all these solid wastes it will amount to several millions of metric tons a  year for each country! #Wastes are materials that we can no longer use in our homes, businesses, industries or elsewhere. Actually they are valuable resources and we have not yet learned how to reuse them as fully as possible, especially in Africa. We do reuse or reclai...

A heat wave or....?

As I write this, I am literally dripping in sweat. Why? You may ask.. it’s  the dry season here in Nigeria and subsequently most parts of Western, Eastern and Northern Africa. Nevertheless and despite the fact that we do experience a lot of heat at this time of the year, this is not normal.  Temperatures have hiked feverishly and can be measured at between 37 to 45 degrees and this shows that the sun is high up in the sky and literally burning hot. Well, as I have been saying for a while now, we with our own hands have brought on this demise by own making. First of all, there are major factors which have contributed to this,  and we all know what they are: #air pollution, indiscriminate  removal of vegetation cover as a result of urbanization; and gas flaring, the result of oil drilling and refining. Air pollution as a result of the release of carbon dioxide and  lead oxide emissions into the atmosphere from old and over used vehicles is one major factor. Secon...

#Industrialpollution of Water

Industrial pollution is  a menace to the aquatic ecosystem. Most factories discharge three or four times more oxygen demanding wastes than sewers and they dump poisons into the water as well. Despite the shift from the industrial era to a more integrated approach as regards knowledge and the advancement of technology, this has and can be seen to remedy some of the impacts of industrial wastes. However, some sources may simply have been eliminated. The average wastes gotten from the modern sulphate, pulp and paper process is less than one tenth of what it was from the sulfite process formerly used in paper mills. So in other words, technology has contributed largely to industrial processes to this regard. Still, new and complex chemical processes are on a frequent basis developed and have increased the possibility of releasing dangerous chemical pollutants that are hard to detect and control.  Most industries are always over eager to introduce new chemicals and materials into ...
