Bisphenol A (BPA) is a synthetic ubiquitous environmental toxicant present in many industrial and consumer products. BPA is recognized as an endocrine-disrupting chemical (EDC), and its mechanisms of perturbation of the physiological process include interference with hormone pathways and epigenetic modifications. An increase in industrial productions and food packaging across Africa has resulted in increased utilization of BPA-containing products with a concomitant increase in environmental bioaccumulation and human exposure. In order to assess the extent of this bioaccumulation, we identified, collated, and summarized the levels of BPA that have been reported across Africa. To achieve this aim, we performed a systematic search of four indexing databases to identify articles and extracted the necessary data from the selected articles. Of the 42 publications we retrieved, 42% were on water samples, 22% on food, 20% on human biological fluids, 10% on sediments, soils, and sludge and 6% on consumer and personal care products (PCPs). The highest level of BPA reported in literature across Africa was 251 ng/mL, 384.8 ng/mL, 937.49 ng/g, 208.55 ng/mL, 3,590 μg/g, and 154,820 μg/g for water, wastewater, food, biological fluids, consumer and PCPs, and semisolids, respectively. This review presented a comparative perspective of these levels relative to regulatory limits and levels reported from other continents. Finally, this review highlighted critical needs for the regulation of BPA across Africa in order to stem its environmental and toxicological impact. We hope that this review will stimulate further research in understanding the impact of BPA on health outcomes and wellbeing across Africa.
