“…POP pesticides and PFOS and its derivatives have been detected in different food items, such as in the residue of rice (Mekonen et al, 2017), cattle meat (Letta and Attah, 2013), fish, fish liver and muscles (Sjöholm, 2015;Ahrens et al, 2016;Melake et al, 2022), khat (Daba et al, 2011), and cow and goat milk (Deti et al, 2014) (Table 7).…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

Over the years, the chemical market has shown significant growth, but the hazardous impact of chemical use and disposal on the environment and human health is a growing concern. Persistent organic pollutants (POPs) are among the most dangerous chemicals with widespread effects on the environment and living organisms, including humans. This study aimed to assess the current status of POP management and regulatory infrastructure in Ethiopia by collecting information from stakeholders responsible for recording the import, export, use, management, and regulation of POPs both in government and private sectors. Additionally, a comprehensive literature review was conducted using Boolean operators from international databases and libraries. The results indicated that Ethiopia banned the import of pesticides listed under Annex A (i.e., those to be eliminated), except endosulfan, which was imported at a quantity of 199,767 kg lt-1 from 2011 to 2015. There are 2,435 PCB-containing transformers in Ethiopia, of which 2,242 (92%) are currently in use. These transformers and capacitors contain 1,031,661 kg and 1,255 kg of dielectric fluids, respectively. As for Annex B POPs (i.e., those to be restricted), there are between 928,509 kg and 1,383,095 kg of active and obsolete dichlorodiphenyltrichloroethane found in different stores across the country. Ethiopia imported approximately 337,000 kg of products containing perfluorooctane sulfonic acid from 2000 to 2020, with an annual average of 16,850 kg of photographic film, paper, and plates. POPs were also detected in different environmental matrices (soil, waterbodies, sediments, food items, and air) as well as human blood. Despite these findings, regulation and management of POP waste and stockpiles are largely inadequate in Ethiopia. Therefore, it is crucial to improve the monitoring, management, and regulation of POPs in the country. This could be achieved by strengthening the collaboration among different regulatory bodies, harmonizing the fragmented laws on POP management and control, and building institutional capacity.

“…Hence, unlike in the developed world, where the assessment and monitoring of PFASs prevalence in the natural environment are at an advanced stage [4], it is only recently that PFAS studies from the sub-Saharan African region have started emerging [54]. Thus, during the last two decades there has been reports on PFAS from South Africa, Nigeria, Kenya, Ethiopia, Ghana, Burkina Faso and Ivory coast, Tanzania and Uganda [4,54,95,96]. It is worth mentioning that the continent has over 50 countries, which suggests that PFAS studies are still limited on the continent at large.…”

“…For example, higher levels of PFOS and PFOA were reported in tap water from Ghana, but lower in tap and bottled water from Burkina Faso [95]. Similarly, PFASs have been reported in wastewater from wastewater treatment plants (WWTPs) and ultimately in several surface water systems in sub-Saharan Africa, including in South Africa, Kenya, Nigeria, Ghana and Ethiopia [54,[95][96][97]. Hence, it can be argued that inefficiently treated wastewater represents a risk to plants, including medicinal plants, to which PFAS-contaminated water is or might be applied to.…”

The history of medicinal plants on the African continent is huge, the oldest and probably the most diverse, for there are thousands of spoken languages, in the sub-Saharan African region, that are used during the traditional practices that utilize medicinal plants for healing purposes. However, our lines of research have exhibited a potential unprecedented threat to this remarkable history of African medicinal plants by emerging pollutants, the per- and polyfluoroalkyl substances (PFASs), which are yet to be efficiently and sufficiently reported and documented on in this region. Accordingly, this review chapter reports on sub-Saharan African medicinal plants with the aim of highlighting how undocumented PFASs, in this region, present a huge threat to the extraordinary diversity of these plants and the therapy that they have assisted the low-income populations of this region with for centuries. Thus, we recommend appropriate and regular assessments and monitoring of PFASs, particularly perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) the most studied of these substances and their substitutes, in medicinal plants of the region, for these chemicals have been scientifically proven to be associated to numerous health concerns. The region should also consider properly regulating these compounds.
