Man’s exploitation of Engineering stimulus is very paradoxical. At one end the state of development is measured in terms of resource (energy) usage and at other end man is concerned about the consequences of the exploitation of the resource which hitherto contributed towards the development of human progress.
A case, where air pollution was attributed to dispersion and suspension of microscopic particulates of a mineral during its mining activity, is put forth in this paper for critical re-appraisal of the reduction in spm (suspended particulate matter) levels below the level mandated as per statutory requirements. The modus operandi employed to abate air pollution, and restrict it below a level of 200 µm per mm3, was spray of water on the ground (mining floor). Ironically the water was drawn from a distance of about 5 Km down the slope (i.e. from a valley) at the expanse of diesel fuel and competitively exploited to its alternative employment for drinking/ potable use for the 250 odd worker population in the mining area. The logistics wherein did not advocate any thing more than austerity of water resource because of its apparent deficiency. The expense of vehicular fuel was certainly an other ‘aspect’ for air pollution.
The paper discusses the gravity of the problem and possible options. Recourse to assessments of various investigators/ implementers of environmental upgradation stimulus towards the foregoing problem is also drawn. The paper concludes by supporting a holistic approach which may be called for towards combating pollution of any type, rather than use a pick and choose system of reactive addressal of the problem.
