Abstract :
:- Concentration of Pollutants from Palla to Agra
d/s was varied from 1.79 mg/l (Palla, 2011) to around 12.00
mg/l (Pall 2014 & Nizamuddin bridge (quarter stream),
2014) . The maximum concentration of zinc 1.37 mg/l was
observed in June, 2015 at Palla. The average of zinc
concentration was in the range of 0.01 (Nizamuddin Bridge
Midstream, 2015) to 0.54 mg/l (Nizamuddin bridgequarterstream, 2014). Significant concentration of heavy metals in
the Yamuna was generally observed either during the lean
flow period or at the onset of monsoon period. These metals
generally reached up to the riverthrough flushing from
various point and non-point sources. At Palla, which is
relatively clean location on the basis of organic pollution,
sometimes high concentration of few metals may
contributed by various large scale electroplating industries
located at Sonepat, upstream town of Palla. At Palla, the
riverbed is silty as compared to other locations, which are
having organic sludge deposition at riverbed. Silt have very
less affinity to absorb the metals as compared to sludge.
This may also be a reason that the metals remain in the
water, if flushed into river instead of their deposition at the
riverbed along with the sludge. The mercury, which was
studied once in a year (June month) at all the locations, was
not traceable in the entire Yamuna stretch during the study
period.
