Analysis of heavy metals in water, sediment and selected fishes of River Sutlej, Punjab, India

Abstract

The study aimed to assess the influence of heavy metal pollution in river Sutlej around the industrial city of Ludhiana. Samples of water, sediment and commercially important selected fish species were collected before (S-1) and after (S-2) the confluence of Buddah Nallah in river Sutlej for the estimation of heavy matals using Atomic Absorption Mass Spectrometer, equipped with transverse graphite furnace tube for electro thermal determination of lead, copper, chromium and zinc. The water, sediment and fish samples collected from the site, S-2 showed higher concentration of heavy metals compared site S-1. All the metals studied were found within the permissible limit of different National and International agencies, except for the lead which was found above the permissible limit in fish, Wallago attu. The results reveal that river Sutlej around Ludhiana city is under severe threat of pollution due to the discharge of industrial effluents from the Buddha Nallah.

Electrokinetic Remediation of Arsenic Contamination From Alluvial and Red Clay Soil

“…The extraction rate and efficiency of heavy metals in electrokinetic remediation are dependent on the physical and chemical characteristics of the soil, and the influence of various factors that may limit the application of electrokinetic remediation is difficult to understand. It is necessary to develop a simple and dependable solution that makes use of easily measurable, less complex but still influential common soil characteristics (Kaur et al, 2019). The main objective of this experimental study is to analyze the extent of removal on two soils (alluvial and red clay soils) by varying individual factors known to influence remediation like different types of electrolytes within practically possible limits of occurrence in field when other factors remain constant.…”

Seasonal Variation, Diversity, and Composition of Planktons in the Ganga River

“…since the biological communities can be considered as the representative of the environmental conditions, biological evaluation is a good indicator of the ecological quality of aquatic systems. Several recent studies on physico-chemical parameters and plankton community of rivers have been conducted on the Yamuna River [8], the Ganga River and its tributaries [9], the Sutlej River [10], and Jhelum River [11]. This study aimed to elucidate the changes in the composition of phytoplankton and zooplankton, their density, and their relationships with different physicochemical parameters.…”

Investigation of Electrokinetic Remediation of Arsenic-Contaminated Two Different Soils (Alluvial And Red Clay Soil) from Tamilnadu

“…Both normal (e.g., volcanic ejection and rock enduring) and anthropogenic (e.g., mining, metallurgy, and bug spray applications) exercises have brought about a huge expansion in As fixation in the soil [3,4]. Moreover, there have been numerous As harming occurrences brought about by mining exercises overall [5]. The worldwide dissemination of As assets is lopsided and the normal estimation of As in soil has been assessed to be 6.83 mg/kg [6].…”
