【 摘 要 】

This study was carried out to determine the quality of rainwater from threedifferent roofing materials (asbestos, aluminum and zinc) in Bodo Community of Rivers State,Nigeria. Samples were taken to the laboratory and analyzed using standard analytical procedures.The average result obtained ranged from 6.0-7.0, 40-66 μsi/cm, 18-48 mg/l, 32.52-86.67 mg/L,0.06-3.18 mg/L, 5.02-13.76 mg/L, 2.79-5.02 mg/L, 0.16-0.77 mg/L, 0.27-5.79 mg/L, 0.24-0.62mg/L and 0.03-4.08 mg/L for pH, conductivity, chloride, salinity, nitrate, sulphate, sodium,magnesium, calcium, iron and zinc respectively. Of interest were rainwater samples fromasbestos roofing sheets which gave high calcium and magnesium content. Also, zinc roofingsheet gave high zinc and iron content compared to other roofing sheets. Physico-chemicalproperties and metal content of the harvested water from the roofing sheets were considerablydifferent from those of control samples (water collected directly from raindrop). This could meanthat the impinging of rain drop on the roof gradually erodes the roof material or could be as aresult of anthropogenic inputs (deposits of pollutants in contact with roofing sheet) orgeographical location. Considering the result of the analysis the harvested water could be put toother domestic use, as they can not be consumed directly.
