Description
Summary:Plastic has become one of the most ubiquitous and environmentally threatening sources of pollution in the Anthropocene. Beyond the conspicuous visual impact and physical damages, plastics both carry and release a cocktail of harmful chemicals, such as monomers, additives and persistent organic pollutants. Here we show through a review of the scientific literature dealing with both plastic pollution and benthic foraminifera (Rhizaria), that despite their critical roles in the structure and function of benthic ecosystems, only 0.4% of studies have investigated the effects of micro- and nano-plastics on this group. Consequently, we urge to consider benthic foraminifera in plastic pollution studies via a tentative roadmap that includes (i) the use of their biological, physiological and behavioral responses that may unveil the effects of microplastics and nanoplastics and (ii) the evaluation of the indicative value of foraminiferal species to serve as proxies for the degree of pollution. This appears particularly timely in the context of the development of management strategies to restore coastal ecosystems. [Display omitted] •Foraminifera are exposed to plastic via inclusion in the test, ingestion and leachates.•We found only four studies on the impact of MPs and NPs on foraminifera.•Plastics alter foraminiferal feeding behavior and induce oxidative stress.•Methodological heterogeneity between studies hampers comparisons.•We suggest a roadmap to address the potential hazard of plastic on foraminifera.
