“…PEparticles provided by the same supplier have already been used in recent studies on effects of microplasics (e.g. Batel et al, 2016;Khan et al, 2015). Two different size classes were used for experiments (particles with 1e4 mm and 90e106 mm in diameter), hereafter referred to as 1-mm and 100-mm particles.…”

“…Accumulation of microplastics along the food chain may thus implicate an additional pollutant pressure by the simultaneous uptake of sorbed (organic) compounds. There are indications from experiments with lugworms (Besseling et al, 2013;Browne et al, 2013), amphipods (Chua et al, 2014) and fish (Khan et al, 2015;Rochman et al, 2013Rochman et al, , 2014) that microplastics can facilitate the transport of pollutants to organisms both in marine and freshwater environments. However, at the moment it is still not clear if the exposure of pollutants carried by microplastics is a relevant pathway to organisms in the environment where pollutants are already present.…”

“…Numerous chemical additives (i.e., plasticizers, antimicrobials) are often incorporated into plastic products during their production, whereas other anthropogenic chemicals (e.g., persistent organic pollutants) can adsorb to plastics once they are released into the environment. Inorganic contaminants such as Ag, titanium dioxide nanoparticles, Ba, S, and Zn have also been found on microplastic debris (Fries et al 2013;Khan et al 2015). Microplastics in the environment have been shown to acquire amounts of persistent organic pollutants (POPs) such as PAHs, PCBs, and other hydrophobic organics within a similar range as those found in the environment (Rios et al 2007;Wang et al 2015).…”

To evaluate the process of trophic transfer of microplastics, it is important to consider various abiotic and biotic factors involved in their ingestion, egestion, bioaccumulation, and biomagnification. Toward this end, a review of the literature on microplastics has been conducted to identify factors influencing their uptake and absorption; their residence times in organisms and bioaccumulation; the physical effects of their aggregation in gastrointestinal tracts; and their potential to act as vectors for the transfer of other contaminants. Limited field evidence from higher trophic level organisms in a variety of habitats suggests that trophic transfer of microplastics may be a common phenomenon and occurs concurrently with direct ingestion. Critical research needs include standardizing methods of field characterization of microplastics, quantifying uptake and depuration rates in organisms at different trophic levels, quantifying the influence that microplastics have on the uptake and/or depuration of environmental contaminants among different trophic levels, and investigating the potential for biomagnification of microplastic-associated chemicals. More integrated approaches involving computational modeling are required to fully assess trophic transfer of microplastics. Integr Environ Assess Manag 2017;13:505-509. © 2017 SETAC.

“…While MPs have not been described in the Nile, other pollutants (i.e., trace metals Cd, Cr, Cu, Fe, Hg, Mn, Pb, and Zn) were found in the abiotic compartments and the tissues of resident fish populations [18]. It is worth noting that MPs have been shown to adsorb trace metals in the environment [69,70], and within the laboratory, polyethylene MPs were shown to alter the bioavailability and uptake of Ag to freshwater zebra fish [71]. The River Congo similarly flows through densely populated cities, notably Kinshasa (14.12 million inhabitants) and Brazzaville (2.21 million), and these waters would also be suspected of having MPs present.…”

As the birthplace of our species, the African continent holds a unique place in human history. Upon entering a new epoch, the Anthropocene defined by human-driven influences on earth systems, and with the recognition that plastic pollution is one of the hallmarks of this new age, remarkably little is known about the presence, sources, and fate of plastics (and microplastics (MPs)) within African waters. Research in marine regions, most notably around the coast of South Africa, describes the occurrence of MPs in seabirds and fish species. More recently environmental sampling studies in the same area have quantified plastics in both the water column and sediments. However, despite Africa containing some of the largest and deepest of the world's freshwater lakes, including Lakes Victoria and Tanganyika as part of the African Great Lakes system, and notable freshwater rivers, such as the River Congo and the Nile, the extent of MPs within the inland waters remains largely unreported. In the only study to date to describe MP pollution in the African Great Lakes, a variety of polymers, including polyethylene, polypropylene, and silicone rubber, were recovered from the gastrointestinal tracts of Nile perch (Lates niloticus) and Nile tilapia (Oreochromis niloticus) fished from Lake Victoria. The likely sources of these plastics were considered to be human activities linked to fishing and tourism, and urban waste. In this chapter we discuss the need for research focus on MPs in Africa and how what has been described in the coastal regions and other freshwater environments can be applied to inland African waters. The aforementioned study in Lake Victoria is used to exemplify how small-scale investigations can provide early indications of MP pollution. Lastly we discuss the current challenges and future needs of MP research in African freshwaters.
