Bisphenol-A (BPA), a plasticizer, used in the manufacture of plastics and a well-known endocrine
disruptor has been known to lead to various health hazards. The present study is aimed at estimating the BPA
content of harvested rainwater in Enugu municipality, Nigeria, hence its preponderance. BPA levels w ere
estimated in harvested rainw ater samples stored in plastic storage drums (n=24) and metal tanks (n=48). All
the 48 storage devices were in constant use for over 6 months and were used to continually harvest rainwater
for domestic uses. 40 drinking tap water samples were also analyzed alongside the rainwater as control. BPA
was analyzed using Ecologenia ® Supersensitive BPA ELISA kit, from Japan Envirochemicals Ltd, Japan. The
results show a statistically significant increase (P=0.0227) in the BPA level of rainwater compared to the
drinking tap water. A comparison of the two storage containers shows a highly significant increase (P= 0.0003)
in the rainwater stored in the plastic containers compared to that in metal containers. BPA tends to be highly
increased in rainwater in the region, possibly due to increased industrialization, with greater amount in samples
stored in plastic containers than that stored in metal containers. This may be attributed to leaching from the
plastics. Both drinking of harvested rainwater from the region and water storage in plastic containers should
be discouraged.
Key words: Preponderance, Bisphenol-A, harvested rainwater, endocrine disruptor, Enugu, Nigeria,
