  A Comparative Study of Seasonal Variability and Photocatalytic Impact on Water Quality of the Ayad River, Rajasthan

  By Chetan Singh, Dipti Soni, Rehana Khanam, Rohitash Kumar, Bhavya Vyas, Rajput Vishakha Ranjitisinh

  Abstract: This study examines seasonal fluctuation in Ayad River water quality, Rajasthan, India and compares the performance of titanium dioxide (TiO2)-mediated photocatalytic treatment under natural sunlight irradiance. Ayad River is a critical source of freshwater for domestic, agricultural and environmental purposes, which is increasingly stressed by urban runoff, industrial effluent and seasonality. As a follow-up to the above, water samples of four important water sources- Thurmadar, Subhas Nagar Bridge (Ayad), Kanpur …

  Dry Season Impact on Water Quality of Nworie River, Owerri, Nigeria

  By Verla Andrew Wirnkor, Anyaorah Francis Chinonye, Shivani Sonkar, Ibe Valentine

  Abstract: This study assessed the physicochemical properties and heavy metal contamination of Nworie River during the dry season. Fifteen composite water samples were collected from strategic points along the river. In-situ measurements of pH, temperature, and electrical conductivity were undertaken, while laboratory analyses determined heavy metal concentrations. Pollution Load Index and Contamination Factor were employed to evaluate the overall water quality and contamination levels. Results indicated moderate to high levels of …
