Detecting Air Pollution

 

Air pollution can be detected, measured and analyzed using a number of methods. First of all, in order to detect gases, a sample of air can be analyzed chemically. Electronic devices make rapid and continuous monitoring. The degree of visibility is another indication of pollution. 

The Ringelmann chart can be easily used to determine the quantity of smoke in the air. This chart bears a series of numbered shadings ranging from zero which is white, then to five, which is black. An observer simply matches the smokiness of the sky with the shading on the chart that corresponds most closely to what he sees. Major areas around the world have established monitoring systems that provide readings of pollution levels at various places within these cities.

 A global network of monitoring stations has thus been established to this effect. This has made extensive use of ground weather stations, earth satellites, computing, the internet and social media to help identify potentially dangerous pollution situations on local levels. But global air pollution is still not very well understood especially in Africa. Data fragmentary and accurate knowledge of large scale effects of air pollution is still sketchy. Still in many countries in Africa and developing countries in Asia, there are no records of combating air pollution. Most times, the governments of these developing countries do not really consider this to be a menace to public and societal health. 

The seriousness of air pollution and its effects on human lives has somewhat been trivialized especially in a country like Nigeria. It is not even considered dangerous or seen as a constituted problem. Hence, there’s been a rise in the level of complacency towards an ever growing problem which has caused and is still causing steadily the slow deaths of members of such countries. 

In Nigeria, for instance, the acute rise in urbanization, which is the agglomeration of people in space, that is to say clustered densely populated areas, has given rise to high levels of importation Of second hand or fairly used cars or automobiles. And many of these cars which have been discarded by the actual owners from developed countries in the European Union(EU) and the United States are the ones that grace the Nigerian roads. When they are put to work on these roads, the release of exhaust fumes from old engines of these already used cars befools the atmosphere. Also fumes from the commonly used tricycles and motor bikes used for commercial transportation all contribute immensely to the pollution of air in the country. 

Furthermore, the indiscriminate burning of forests and bushes, the burning of refuse in open dumps, and the inadequate disposal methods of solid and liquid wastes coupled with heavy land pollution has lead to increased levels of polluted air and reduced drastically the quality of air that we breathe. Tuberculosis, for instance, between  the year 2012-2015, there was a rise in cases of this respiratory disease in cities like Warri, in the Niger Delta region of Nigeria.

 Also, the pollution from electric power generating plants is also on the rise. As a result of the energy problem in the country, the instability of electricity has led to the massive acquisition of generating plants on an unprecedented scale. Individuals, small and large businesses, and every body in general have acquired this necessity to help power their businesses and also provide light and electricity to ensure comfort in their homes. 

Often times, extreme care is disregarded and people often go to bed with their generating plants on all through the night without ensuring that there’s adequate ventilation while they sleep. However, there have been acute cases of whole families wiped out as they inhaled the dangerous exhaust fumes from their generating plants while they slept.

#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 ...
