What remains unsolved in Sub-African environmental exposure information disclosure : a review

Background: Africa comprises the bulk of struggling economies. However, Sub-Saharan Africa is experiencing rapid industrialization and urbanization. Excessive resource use, pollution, and the absence of relevant environmental disclosure are factors that contribute to these human-made damages. Environmental pollution as a threat to sustainable development results from these damages. Although it has been established that Sub-Saharan Africa would benefit from resource-management development, sustainable environmental strategies, and a reduction in urbanization and persistent poverty, the information on these issues has not been made public. Objective: To provide a full account of the level of environmental-exposure disclosure in Sub-Saharan African countries, including the current level of progress, gaps, and prospects, we reviewed the literature on environmental exposure information research in African populations. Methodology: We searched PubMed and Google Scholar for peer-reviewed research articles, reviews, or books examining environmental exposure and information disclosure in human populations in Africa. Results: In total, 89 full-text articles were eligible for the inclusion criteria. A quality assessment of the retrieved articles using the PRISMA guidelines resulted in the exclusion of 40 articles; therefore, 49 studies were included in the final analysis. In Sub-Saharan Africa, the environmental exposure information on household injuries, the use of chemicals such as pesticides in farming, industry-linked vectors and diseases, laboratory chemical exposure, industrial exposure, and epigenetic factors are not well-disclosed to the population. Conclusion: Environmental information disclosure standards should be incorporated into central-government policy recommendations. Standards should identify polluting industries, and companies should refrain from the voluntary disclosure of environmental information to manage their reputation. Heavy-pollution industries should be made sufficiently transparent to lessen the company–media collusion on information disclosure.
