Abstract :This study investigated the effects of prolonged storage conditions on the physicochemical parameter, toxic metals, microbial loads, and health risks assessment of randomly selected three brands of sachet and bottled water in North Central, Nigeria. One hundred eighty samples of water brands insert ignore into journalissuearticles values(sachet and bottled); were collected from 10 different factories and were grouped into three. They were analyzed immediately insert ignore into journalissuearticles values(initial);, being exposed to mild sunlight insert ignore into journalissuearticles values(stored with a container); and exposed to intense sunlight insert ignore into journalissuearticles values(stored without a container); conditions for six weeks. The results of the physicochemical parameters insert ignore into journalissuearticles values(sachet and bottle); were within the limits set by the World Health Organization insert ignore into journalissuearticles values(WHO); and the Standard Organization of Nigeria insert ignore into journalissuearticles values(SON);. While the results of heavy metals analysis for both sachet and bottled water recorded 0.15 - 0.51 mg/L insert ignore into journalissuearticles values(0.10 mg/L , 0.05 mg/L);, 0.13 - 0.38 mg/L insert ignore into journalissuearticles values(0.015 mg/L, 0.01 mg/L); and 0.55 - 1.11 mg/L insert ignore into journalissuearticles values(0.03 mg/L, 0.3 mg/L); for Chromium insert ignore into journalissuearticles values(Cr);, Lead insert ignore into journalissuearticles values(Pb); and Iron insert ignore into journalissuearticles values(Fe); respectively, as compared to the permissible limits insert ignore into journalissuearticles values(values in the bracket for each heavy metals); set by WHO and SON. The microbial analysis results ranged between 6.58 - 124.51 Cfu/100 mL, 0.52 - 37.56 Cfu/100 mL, 0.07 - 5.00 Cfu/100 mL, 0 - 2.07 Cfu/100 mL for Total Bacteria Count insert ignore into journalissuearticles values(TBC);, Total Coliform Count insert ignore into journalissuearticles values(TCC);, Faecal Coliform Count insert ignore into journalissuearticles values(FCC); and Total Fungal Count insert ignore into journalissuearticles values(TFC); respectively, which showed no effective quality control system. Incremental lifetime cancer risk insert ignore into journalissuearticles values(ILCR); assessment revealed a carcinogenic health risk to the populace drinking this water. The study concludes that water stored under sunlight for a long period is not good for human consumption and therefore adequate monitoring by the appropriate agencies is emphasized.
