Micro-plastic ingestion by waterbirds from contaminated wetlands in South Africa,

Abstract:

Despite a large literature on the impacts of micro-plastic
pollution in marine ecosystems, very little research has focused on
these pollutants in freshwater ecosystems. Recently, however, a few
studies have demonstrated that micro-plastic pollutants are ingested by
freshwater taxa, including birds. To explore this potential
environmental threat in African freshwater systems we quantified
micro-plastic pollutants in the faeces and feather brushings of seven
southern African duck species. We analysed 283 faecal samples and 408
feather brushings, and found that 5% of faecal samples and 10% of
feather samples contained micro-plastic fibres. The presence and
abundance of micro-fibres differed between sampling sites, with
significantly higher amounts recorded for the site that received
effluent from a sewage treatment facility. Additionally, micro-fibre
presence differed across duck species, indicating that foraging
behaviour affects plastic ingestion. Our study confirms that African
freshwater ecosystems and the biodiversity they support are under threat
from micro-plastic contamination.
