Abstract
The concentration of heavy metals (Fe, As and Cu) was examine in riverbed sediments of Gomti river, Lucknow at selected sites in pre and post monsoon season for three consecutive years (2009-11). The concentration was ranged between (As: 0.07-0.7, Fe: 7462.00-7977.00, Cu: 10.98-36.73 μg g-1) in pre-monsoon and in post-monsoon metal concentration was ranged between (As: 0.05-0.07, Fe: 543.00-7797.00, Cu: 32.00-9. 23 μg g-1). Whereas Geo accumulation index (I geo), contamination factor (CF), US EPA guideline also apply to determine the readily toxicity. Fe and As pollution was found from negligible to low level while Cu leads from low to moderate pollution. Significant correlation found between the metals in pre and post-monsoon of studied years, in case of As it was found insignificant. Conservation and management plan is also suggest for contaminated sites.Keywords: Gomti River, Heavy metals, Contamination factor, Geo-accumulation index
Highlights
Pollution of heavy metals in the aquatic environment has noticed by researcher and scientists worldwide due to its abundance, persistence and environmental toxicity (Ali et al, 2016).Overload of contaminations both organic and inorganic produce huge load, which distorted water quality and adversely affected the rich biodiversity of the rivers (Gaikwade and Kamble, 2014)
Sediments of the rivers are the major factor for the assessment of the pollution introduce by anthropogenic activity, in the case of heavy metals pollution river sediments played important role in both the ways as sources and sink of heavy metals
Industrial waste like vegetable Oil, milk dairy, and other industrial and sewage waste are dumped in the river (Araya et al, 2011).The aim of this study is to investigate and report the temporal and seasonal variation of As, Fe, and Cu pollution in sediments of river Gomti in vicinity of Lucknow city India with special conservation and management plan
Summary
Pollution of heavy metals in the aquatic environment has noticed by researcher and scientists worldwide due to its abundance, persistence and environmental toxicity (Ali et al, 2016).Overload of contaminations both organic and inorganic produce huge load, which distorted water quality and adversely affected the rich biodiversity of the rivers (Gaikwade and Kamble, 2014). Pollutants/contaminants settled down in the sediments along with water flow and pollute/contaminate sediments for many kilo meters, metal pollution of river sediments become burning issue in concern of aquatic environment of the rivers (Marathe et al, 2011). Industrial waste like vegetable Oil, milk dairy, and other industrial and sewage waste are dumped in the river (Araya et al, 2011).The aim of this study is to investigate and report the temporal and seasonal variation of As, Fe, and Cu pollution in sediments of river Gomti in vicinity of Lucknow city India with special conservation and management plan
