Abstract:

Water and sanitation as relates to sustainable development goal are of great importance. The uses of water can generate wastewater and poor management causes pollution which leads to human and environmental changes. Discharge of Industrial wastewaters to water bodies is a common practice in developing country. The presence of chemicals in effluent could constitute a threat to human health, aquatic habitat, and plants. There is, however, some dearth of information on this in Liberia. This study, therefore, is to access the degree of toxicology in wastewaters from selected industries in Monrovia, Liberia. Wastewater samples were collected from five industries: Brewery, Paint, Battery, Rubber and Petroleum, and were transported to the laboratory in the ice pack. Heavy metals (Cu, Zn, Pb, Fe, Cr and As) were analyzed while toxicological potentials of the industrial wastewater were evaluated by standard procedures using Allium cepa and male albino rat. Data were analyzed using the Student t-test. There were elevated levels of physicochemical parameters (BOD 807; COD 915?g/l), heavy metals (Cu, 35.30; Zn, 42.40; Mn, 0.22; Pb, 0.50; Fe, 9.30; Cr 0.79; As 0.24 mg/Kg). Chromosomal aberration in Allium cepa and exposed male albino rats were observed. The mutagenic index increased significantly for brewery and battery above the negative control at 5% concentration. Similarly, all the wastewater samples were genotoxic at 50% concentration. The toxicological level of this wastewater has public health implication. Therefore, stringent policies and renovative measures are needed for monitoring industrial waste for viable life in Liberia.
