Surface water quality monitoring in Sulaymaniyah Governorate, Iraq: polycyclic aromatic hydrocarbons, major anions, physicochemical parameters, and seasonal trends

Environmental Impact Assessment of Polycyclic Aromatic Hydrocarbons (PAHs) and Heavy Metals in Rivers and Creeks around Gokana LGA, Rivers State

This study assessed the environmental impact of polycyclic aromatic hydrocarbons (PAHs) and heavy metals in water, sediment, and biota from fifteen (15) sampling stations along the Bodo River in Gokana Local Government Area, Rivers State, Nigeria. The primary objective was to evaluate the concentration levels of PAHs a...

Seasonal variations in groundwater quality parameters and their ecological implications in oasis of Tamaghza, governorate of Tozeur, Tunisia

Assessment of Groundwater Quality, Contamination Risk, and Hydrogeochemical Characteristics Around Okitipupa Dumpsites, Southwestern Nigeria

Groundwater contamination from unmanaged dumpsites threatens water quality and public health in many developing countries. This study evaluated the physicochemical properties and contamination risk of groundwater around dumpsites in Okitipupa, Ondo State, Nigeria, during the dry season, January 2025. Sixteen samples we...

Assessment of water quality of Dhansiri River at Interstate Boundary of Assam and Nagaland (North-Eastern India) using Principal Component Analysis

Effective management of transboundary river systems is a critical global challenge, particularly in developing regions where water quality degradation can fuel interstate conflict and hinder sustainable development. This study applies Principal Component Analysis (PCA), a robust multivariate statistical technique, to e...

Assessment of physicochemical and metal characteristics of effluent in Ebonyi State, Nigeria, implications for aquatic ecosystem health and food security

Industrial and domestic effluent discharge contributes significantly to surface and groundwater pollution. Industrialisation in rapidly urbanising regions of Sub-Saharan Africa often impacts the environment, leading to severe aquatic degradation. This study presents a comprehensive physicochemical, metal, and toxicolog...

Seasonal variability of organochlorine pesticides, polychlorinated biphenyls, polycyclic aromatic hydrocarbons and benzene, toluene, ethylbenzene and xylenes in the Sitnica River, Kosovo, under contrasting hydrological conditions

This study assessed the seasonal variability of physicochemical conditions and selected organic pollutants in the Sitnica River, Kosovo, under contrasting hydrological conditions. Surface water samples were collected from 15 monitoring stations during a high-flow campaign in February/March 2023 and a low-flow campaign...
