When seeking to define pollution, a very useful reference point is the ambient quality of the physical environment. Basically, physical environment refers to the natural state of the environment without the interference by mankind.
Based on the above scenario, pollution can therefore be explained as a lowering or reduction of the ambient quality of the physical environment as a result of the activities of human.
Pollutants can classified taken into consideration three key elements:
The first key element has to do with chemical and physical properties. This usually explain a situation whereby pollutants are classified into organic compounds(detergents, oil, solvents, etc), inorganic compounds ( acids, salts,, etc) ,infectious agents (virus, bacteria, etc) and energy firms ( radioactive waste).
The next element is the source of emission which is classified into three of which are:
1st: Cumulative and non-cumulative pollutants:
these are non-biodegradable , for instance, plastic and radioactive waste whiles the non-cumulative are biodegradable , for instance noise.
2nd: Point sources and non-point sources pollutants:
these are pollutants whose source point of emission can be traced and identified, eg. carbon monoxide, whiles non-point source pollutants are those that cannot be identified, eg. fertilizer washed away into water bodies.
3rd: Continuous and episodic pollutants:
Continuous pollutants are generated on the routine bases. eg. carbon monoxide from engines
whiles the episodic pollutants on the other hand are generated occasionally. eg. chemical fertilizers been washed into water bodies.
The last key element and also prominent among the all has to do with the geographic scale of the impact of the pollutants.
The above element reveals three levels of pollutants, thus the global, regional and local pollutants.
Global pollutants emitted locally with a potential world wide impact. eg. the emission of chlorofloro carbon (CFC) on the ozone layer in the worlds stratosphere.
Regional pollutants emitted locally but the impact extends beyond the geographic boundaries of the source of emission but not world wide. eg. carbon monoxide , waste disposal, etc.
Local pollutants emitted locally with a potential local impact. eg. smoking, intensive local pollution is also prevailing in most cities in China and India.
Sixteen of the the twenty world polluted cities are situated in China. Serious pollution has long term health and environmental damages or effects.
China and most developing countries of which Ghana is among are now exchanging good health and healthy environment for industrial gains.
Lets go green to protect and safeguard our environment for our common future.
