Abstract The Niger River, threatened by human activities, is the main drinking water source for population of Bamako city. This study assesses trend River pollution in using Water Quality Index (WQI). Fourteen parameters, namely Turbidity, Potential Hydrogen (pH), Electrical Conductivity, Dissolved Oxygen, Total Solids, Biochemical Oxygen Demand (BOD5), Chemical (COD), Nitrate, Nitrite, Ammoniu...

The Mirim Lagoon is one of the most important freshwater lagoons in Brazilian territory, connecting Patos through São Gonçalo Channel. With diversification uses rivers, watersheds, and lakes, sustainable management these ecosystems are extremely relevant. For this reason, monitoring environments great importance. In view above, water quality index (WQI), trophic state (TSI), statistical methods...

Groundwater is germane to human existence. The study assessed the physicochemical attributes of groundwater for domestic and irrigation applications. This was conducted by collecting subjecting thirty (30) samples analysis. Thirteen parameters such as pH, electrical conductivity, total dissolved solids, hardness, magnesium, calcium, sodium, iron, fluoride, chloride, sulphate, nitrate, phosphate...

This study aims was to identify impact of economic development factors the environment quality by using Kuznet's Curve Hyphotesis and non linear regression. The determinants studied are indicators such as Gross Domestic Regional Income (GDRI) industrial sector, mining agricultural/plantation /forestry/fishery/livestock sectors, poverty, unemployment human index (HDI). While environmental used W...

This paper analyzes water quality from four hydrological stations in the Nišava river basin 2009–2018 based on following parameters: pH, conductivity, O 2 saturation, BOD 5 , suspended solids, total oxidized nitrogen, phosphates, turbidity and coliform bacteria. Authors have applied WQI (water index) as most reliable indicator of watercourses pollution for setting surface flow quality. Statisti...
