Abstract:
Industrialisation of a country is a symbol of
dQvelopment, more are the industries in a country,
more developed it is. 1hese industries are being installed
near big cities etc and du8 to these industries there is
likely to be some changes in environmnent. Many probl erns are created due to this change and the major problem is of
pollution of air and water.
Water is said to ,_ e polluted when its eompo si tion
ar condition or both is altered making it unsui?able or less
suitable for the purposes for which it would be suitable in
its natural st??e. Water pollution includ?s not only physical
and chemical changes 1· ut also biological properties of water,
making it harmful to pu' lie heal th, domestic use, eommercial,
industrial, agriqulture, recreational or other uses of water
or liue stock, wild life, fish or other aquatic life.
Water pollution is caused by many ways. It may be
accidental but it is mainly caused due to uncontrolled
disposal of sewagJ and other liquid wastes from domestic use,
,
· industrial wastes, drainage of irrigation water and Lrrban
run off etc. The disposal of was e water is becoming serious
problem in main ur! an cities of Pakistan. ---.. The purpose of present investigation was to estimate
··quanti tati vel ythe chemical pollutant and its possible causes
for drinking waters, river waters -and industrialwaste water
in NNFP Pakistan. The drinking water which was studieed was from
the districts of Peshawar, Mardan, Kohat, Bannu and D.I.Khan.
The industrial waste water was from Nowshera industrial area
and river water was ta?en from River Kabul into which the
industrial wastes of Nowshera are dro?ped.
Various analytical techniqueswere applied for this
investigation. These include palarography, atomi c asbo rp t.Lon
spectrophotometry, Flame photometry, and other techniques for
the measurements of various parameters like D.O,B.O.D,C.O?D,
Na,K,Ca,Fe,Mg,Ni,Cu,Zn,pH, turbidity alkalinity and so-on. The industrial waste wer,' studied for pollution from
the origin and from various location of the waste stream on
their path to the river, to show the various chemicals
di.s cb ar+cd by the indust:r.ies andto get the change in it upto
the river. The Kat·ul River samples were studd e-d from the river
bank and from the middle of the river at a depth of th?ee mrt?rs
The samples were co Ll e ct.ed wh sn the .ri vorwa s in normal pace i.c
there was no flood situation and no rainy season. The results
