Groundwater quality enumeration and health risk in the extended part of Chhotanagpur granite gneiss complex of India.

The majority of people on the earth bank largely on groundwater to quench their thirst. In the era of rapid population growth, the over-exploitation of groundwater gives rise to water scarcity, and people find themselves in distress to manage safe drinking water. In this backdrop, the present study is carried out in the terrain of Pre-Cambrian igneous and high- to low-graded metamorphic rocks, to assess the groundwater potential zones (GWPZs) and evaluation of groundwater quality.

Impact of COVID-19 lockdown on the water quality of the Damodar River, a tributary of the Ganga River in West Bengal.

Unlabelled: The COVID-19 (SARS-CoV-2) pandemic is wreaking havoc on the planet, yet control of waste materials comforted the ecosystem during the lockdown restricting human activities. Damodar is the most important tributary of the lower Ganga River in West Bengal. It flows through an industrially developed, agriculturally flourished populated area.

Evaluation of spatio-temporal variation of water quality and source identification of conducive parameters in Damodar River, India.

The lower course of the Damodar River in West Bengal is one of the most polluted stretches in the Ganga River basin. There is a lack of research along the whole course of the Damodar, and parameter level analysis receives little attention. Eleven monitoring sites were chosen based on the potential sources of pollution for 6 years (2014-2019).

Assessment of adverse outcome of Excel Mera 71 in Anabas testudineus by histological and ultrastructural alterations.

Present study was designed to evaluate the adverse effect of glyphosate-based herbicide, Excel Mera 71 in Anabas testudineus on comparative basis under field and laboratory conditions. Field (750 g/acre) and laboratory (17.2 mg/L) experiments were performed for a period of 30 days.

Toxicity assessment of agrochemical Almix in through histopathological alterations.

The present study was designed to assess the adverse effects of the agrochemical Almix on comparative basis in gill, liver and kidney of through histological and ultrastructural observations under field (8 g/acre) and laboratory (66.67 mg/L) conditions. Exposure duration of both experiments was 30 days.

Effects of almix herbicide on profile of digestive enzymes of three freshwater teleostean fishes in rice field condition.

The present investigation was carried out to compare the alterations of digestive enzymes like amylase, lipase, and protease activities in three teleostean fishes ., , and after application of almix herbicide for 30 days at rice field concentration , 8 g/acre. Highest amylase activity was observed in intestine of (300.
