The Role of Particulate Matter in Air Pollution

 

Particulate matter causes the frequent painting of houses, cleaning of clothes and washing of cars. Particulate matter, nitrogen oxide and sulfur oxide are all contributing factors to decreased visibility. 

This however, presents a hazard to operators of aircraft, automobiles and boats. A study revealed that levels of harmful microscopic particulate matter known as PM 2.5 and the pollutant which is smaller than PM 2.5 micrometers in diameter is considered particularly dangerous as it can lodge deep into the lungs and pass onto other organs and the blood stream, causing serious health risks. 

The effects of air pollution on weathers and climate aren’t far fetched. Scientists have definitely established a relationship between air pollution and weather. Each can affect the other in numerous ways. Wind and temperatures for instance affect the quantities and extent of pollutants in the air. Strong winds are air currents which may scatter pollutants in both vertical and horizontal directions. The two pollutants, however, that have major effects on climate are Carbon(IV)Oxide And particulate matter. Carbon IV Oxide tends trap heat in the lower atmosphere. Particulate matter however has the opposite effect in that it tends to reflect solar heat back into space. A marked increase in one of the following could cause a global warming as is the current global climate crisis, or a cooling trend. 

So, in other words, an increased level of particulate matter causes a deflection of heat back into space and this causes a cooling trend. Therefore, areas or regions on the earth’s surface not experiencing enough heat or radiant energy could be plagued with particulate matter in the atmosphere. 

Furthermore, another perfect example of the local effects on weather is the increase in precipitation. Like the amount of rainfall  experienced in cities and regions where large paper mills are adjacent to them. Particles from these mills act as nuclei around in which rain drops form. 

Climate change in the Niger Delta areas and regions of Nigeria where gas flaring as a result of oil drilling activities have taken its toll, the weather pattern changes have all been to glaring and are evidently displayed all year round. In the past few years, from 2015 till date, the region has experienced heavy rainfall beginning sometimes as early as January, instead of the usual time in April, and during the The dry season which is the African summer, there’s been an acute rise in temperatures making atmospheric conditions unbearably hot.

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. Secondly, bush burning, relea

Development and Good Governance

The Development of a society, country or nation means that there is a balance in all facets of society, integrated to ensure transformation and sustainable growth. Government on the other hand, is a term which broadly understood, means the ordering of a group or community by a central organization or it may refer to central organization itself. Thus, we may speak of a government of a club, private association or a church, as well as the government or state or   bodies politic. But when narrowed to its political meaning, government refers to the management or administration of the state. And for the purpose of this study we will look at it from this angle. The findings of anthropology suggest that the origins of the governments are tribal and monarchic: primitive societies are generally based on familial relationships, and authority is often times exercised either by a man (patriarch) or by a woman (matriarch), recognized by the others as the leader. Until the last two centuries and

#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 reclaim some paper,
