This study shows that the energy reserves of lugworms living in sediment contaminated with microplastic particles were reduced by up to 50%. http://ec.europa.eu/environment/integration/research/newsalert/pdf/365na2.pdf

Wright, Darren Rowe, Richard C. Thompson, Tamara S. Galloway, Microplastic ingestion decreases energy reserves in marine worms, Current Biology, Volume 23, Issue 23, 2 December 2013, Pages R1031-R1033, ISSN 0960-9822, http://dx.doi.org/10.1016/j.cub.2013.10.068. (http://www.sciencedirect.com/science/article/pii/S0960982213013432) Abstract: Summary The indiscriminate disposal of plastic to the environment is of concern. Microscopic plastic litter (<5 mm diameter; ‘microplastic’) is increasing in abundance in the marine environment, originating from the fragmentation of plastic items and from industry and personal-care products [1]. On highly impacted beaches, microplastic concentrations (<1mm) can reach 3% by weight, presenting a global conservation issue [2]. Microplastics are a novel substrate for the adherence of hydrophobic contaminants [1], deposition of eggs [3], and colonization by unique bacterial assemblages [4]. Ingestion by indiscriminate deposit-feeders has been reported, yet physical impacts remain understudied [1]. Here, we show that deposit-feeding marine worms maintained in sediments spiked with microscopic unplasticised polyvinylchloride (UPVC) at concentrations overlapping those in the environment had significantly depleted energy reserves by up to 50% (Figure 1). Our results suggest that depleted energy reserves arise from a combination of reduced feeding activity, longer gut residence times of ingested material and inflammation. http://download.cell.com/current-biology/pdf/PIIS0960982213013432.pdf
