Pollution Status of River Hindon from Ghaziabad to Noida with Special Reference to Heavy Metals
Keywords:
River Hindon, Heavy metal pollution, Correlation analysis, Industrial effluents.Abstract
The objective of the present study is to investigate the current status of heavy metal pollution in River
Hindon, from Ghaziabad to Noida stretch. The concentrations of Nickel, Cadmium, Chromium, Copper, Iron,
Manganese, and Zinc in water samples have been studied during January 2013 to December 2014. The overall
mean concentration of heavy metals was observed in the following order Fe > Mn> Zn > Ni > Cr > Cu > Cd. Cu
and Zinc was found below the standards of WHO and CPCB. The iron was found in maximum concentration and
Cd was found in minimum concentration. The average values of all the heavy metals were found as Fe
(11.27±3.50), Mn (4.00±1.26), Ni (0.63±0.17), Cr (0.16±0.07), Cu (0.15±0.07), and Cd (0.08±0.07). Based on
heavy metal pollution analysis we concluded that our study area as a whole is critically polluted with heavy metals
under study due to pollutant load from various anthropogenic activities. One way ANOVA shows statistically
significant differences in the levels of all the studied heavy metals between different sites. Games Howell post hoc
test shows that there are statistically significant differences (p<0.05) in the levels of all the studied heavy metals
between Hindon barrage, Indrapuram, Vishnu Nagar and Dadri Road.
