Quality of Water Runoff Discharged from Some Industries into the Isolo Canal, Lagos

摘要

A study was conducted for the analysis of pollution load in industrial effluents from 6 industries in Ilupeju Industrial Estate, Lagos. Main drains from these industrial units which included chemical, soap and oil, textile, pharmaceutical and steel industries were analyzed for various physical and chemical parameters like temperature, pH, salinity, anions and heavy metals content. Analysis of the samples collected over a period of 7 months showed that most of the parameters investigated exceeded the federal environmental protection standards for effluents.
