Seasonal assessment of water pollution in the Hindon River with reference to physico-chemical, microbial and Heavy metal contamination Devendra Kumar, Laxmi Kant Bhardwaj, Hariom Tyagi, Swapnil Rai, Kuldeep Dwivedi, Arun Kumar Sharma Environment Conservation Journal, 2026 The Hindon River is considered one of the major branches of the River Yamuna in the plain region. The river is utilized as a major water source in the populated rural area of western Uttar Pradesh. Due to the dense agricultural and industrial activity along the river, the river is becoming highly polluted. The current study involves the estimation of the water quality of the Hindon River at selected sampling locations by monitoring the physicochemical, heavy metal, and microbiological parameters. Water samples from selected sites (Town-Budhana, District-Muzaffarnagar, Village-Baparsi, District-Meerut, and Village-Surana, District-Ghaziabad) were collected in triplicate in the seasons of pre-monsoon, monsoon, and post-monsoon during the year 2022-2023. Physicochemical analysis revealed significant pollution across all the sampling locations. The pH and temperature varied from 6.79 to 7.89 and 25.97 to 30.23°C, respectively, across all sites. Electrical conductivity ranged from 737.4 to 1113.34 µS/cm, color ranged from 12 to 32 Hazen, TDS ranged from 528 to 765 mg/L, TSS ranged from 65.7 to 241.67 mg/L, and turbidity ranged from 23.70 to 55.26 NTU. The range of alkalinity was 346.7 to 633.33 mg/L, dissolved oxygen was 0.76 to 4.30 mg/L, BOD was 25.0 to 206.67 mg/L, and COD was 82.0 to 456.67 mg/L. The ranges for total hardness were 316.7 to 513.33 mg/L, sulfate 12.96 to 26.16 mg/L, nitrate 8.52 to 26.98 mg/L, fluoride 0.14 to 0.44 mg/L, and total coliforms 1.43 to 4.07 × 10⁻² MPN/100 mL. E. coli was found in every sample. Sampling site-3 was found with the highest level of contamination with high ecological risk. The results show that water from the Hindon River is unsuitable for consumption and requires potential control measures.

Investigation of Ambient Air and its Quality around University Campus and National Highway (NH-92) at Etawah Road, Gwalior, India G.K. Singh, S. Rai, N. Jadon Research Journal of Chemistry and Environment, 2022 A continuous study of ambient air quality is necessary for determining a regional environmental condition, mainly air pollutants. Pollutant concentrations, sources and weather conditions all have an impact on the quality of the air we breathe. The current study attempted to investigate the air quality in Gwalior city by using two separate locations. In urban areas, the contribution from automobile sources has the most significant impact on air quality. High levels of air pollution have a variety of harmful health consequences. The air quality inside/outside of the university campus is evaluated in this study. Air pollution has serious health consequences for humans, animals and plants. It is difficult to predict the health effects of low-level exposure. The World Health Organization has specified the various criteria gases that affect human health and crops. Different pollutants, mainly Particulate Matters, i.e. PM10, PM2.5, SOx, NOx and SPM, are investigated and their concentration is also estimated for comparative study.
Assessment of Particulate Matters Especially PM2.5 and PM10 Concentration During and Before Lockdown in the Various Metropolitan Cities of India Gourav Kumar SINGH, Shivom SINGH, Swapnil RAI, Nimisha JADON Journal of Environmental Management and Tourism, 2022 This study was carried out to evaluate the concentration of particulate matter i.e. PM2.5 & PM10 in the selected metropolitan area (Mumbai, Delhi, Kolkata & Bengaluru). Data used and analysed in this research was taken from the official website of CPCB (Central Pollution Control Board). Analysis is done before and during the lockdown period. For the current analysis, data from the chosen parameters (Particulate Matter with a diameter equal to or less than 10 microns (PM10) and particulate matter with a diameter equal or less than 2.5 microns (PM2.5) are gathered and analysed from the source i.e. CPCP. Site wise, histogram analysis was also performed. The PM concentration is found to be the highest in Delhi, among all locations. During the study period, a clear association between PM10 and PM2.5 was observed at all the sites. A great change was observed in the values of Particulate Matter before and after the lockout cycles. In metro cities, values higher than PM10were found to be PM2.5, except for Bangalore, where values lower than PM10 were found to be PM2.5. During the lockdown, Bengaluru was least polluted while Delhi was the most polluted city among all these metropolitan cities. During the analysis it was observed that the level of Particulate Matter (PM) got reduced as all kind of anthropogenic activities were stopped. Vehicular activities and other construction work were also stopped so it helped to reduce the PM from the surroundings. COVID-19 brought a meaningful drive to combat all kind of air related pollution and it is observed during this research.
Major ambient air pollutants and toxicity exposure on human health and their respiratory system: A review Gourav Kumar SINGH, Swapnil RAI, Nimisha JADON Journal of Environmental Management and Tourism, 2021 Indoor and outdoor air pollution is causing environmental and health issues globally. It is more challenging mainly in developing countries like India, china, and others.According to recent World Health Organization (WHO) reports, nearly 4.2 million people die prematurely because of AAP (Ambient Air Pollution). Air pollution is made up of a variety of contaminants, including gases, liquids, heavy metals in the air, and particulate matter. Suspended particulate matter (SPM), surface ozone (O3), sulfur dioxide (SO2), nitrogen oxides (NO2), and other contaminants have become major environmental threats to plant health. These pollutants also have an effect on human health because they affect the consistency of the air we breathe. They usually cause inflammation in the upper respiratory tract, resulting in cough and shortness of breath. These are also significant contributors to the exacerbation of current respiratory conditions like asthma and chronic obstructive pulmonary disease. Epidemiological, toxicological, and clinical research all support the connection between air pollution and increased incidence and severity of respiratory and cardiovascular diseases. This pollution is a major public health problem in the locations where maximum pollution sources exist. To improve air quality and reduce the adverse effects of airborne toxicity due to AAP on human health, significant approaches are needed. The main objective of this review article is to provide evidence on the adverse effects of AAP on human health, as well as to make recommendations to policymakers on how to minimize exposure to this risk factor. Only public awareness combined with a multidisciplinary approach by scientific specialists will be able to handle this problem; national and international organizations must address the rise of this threat and suggest long-term remedies.
