“…Similar conclusions were drawn by Browne et al (2013) after exposing the annelid A. marina to sand with PVC microplastics pre-sorbed with nonylphenol and phenanthrene.. The observed desorption realized during digestive processes has ecotoxicological implications since it has been speculated that the bioconcentrated chemicals may induce adverse biological effects in aquatic organisms potentially able to unpair key ecophysiological process (Oliveira et al, 2013;Bakir et al, 2014;Luís et al, 2015). To determine whether plastic microparticles are capable of transporting levels of pollutants able to disrupt functions of ragworms, we used established bioassays for mortality, immune system efficiency estimation, index of sub cellular functioning and oxidative stress assessment.…”

Plastic micro litter represents an emerging contaminant as well as a multiple stress agent in aquatic environments. Microplastics are found even in the remote areas of the world. Together with their occurrence in all environmental compartments, there is a growing concern about their potential to adsorb pollutants co-occurring in the environment. At present, little is known about this source of exposure for aquatic organisms in the benthic environment. Exposure conditions were set up to mimick the contribution of microplastics through different exposure routes. Potential biological effects resulting from these exposures were investigated in the model organism Hediste diversicolor, an annelid worm. Cellular effects including alterations of immunological responses, lysosomal compartment changes, mitochondrial activity, oxyradical production and onset of genotoxicity were assessed in coelomocytes while temporary and permanent effects of oxidative stress were also performed at tissue level. In this study polyvinylchloride (PVC) microparticles were shown to adsorb benzo(a)pyrene with a time and dose-dependent relationship. The elevated bioavailability of the model pollutant after ingestion induced a clear pattern of biological responses. Toxicity mainly targeted impairment of cellular functioning and genotoxicity in H. diversicolor coelomocytes, while permanent effects of oxidative stress were observed at tissue level. Coelomocytes responded fast and with a higher degree of sensitivity to the adverse stimuli. The results showed that microplastic particles in sediments may play a significant role as vectors for organic pollutants. The highest adverse responses were observed in those H. diversicolor exposed to sediments spiked with PVC particles pre-incubated with B[a]P when compared against sediments spiked with B[a]P and plastic microparticles separately.

“…While most researches on the toxic effects of MPs have focused on aquatic organisms, studies documenting the potential health risk and tissue accumulation of MPs in mammals are lacking. Tissue accumulation of MPs may induce various adverse effects, such as physical injury22, reduction of feeding activity23, inhibition of growth and development24, energy deficiency3, immune responses25, oxidative stress26, neurotoxic responses27, metabolic disorder28, and genotoxicity13. Hence, data on tissue accumulation of MPs in mammalian models would be indispensable for risk assessment of MPs in human health.…”

Microplastics (MPs) are a significant environmental health issue and increasingly greater source of concern. MPs have been detected in oceans, rivers, sediments, sewages, soil and even table salts. MPs exposure on marine organisms and humans has been documented, but information about the toxicity of MPs in mammal is limited. Here we used fluorescent and pristine polystyrene microplastics (PS-MPs) particles with two diameters (5 μm and 20 μm) to investigate the tissue distribution, accumulation, and tissue-specific health risk of MPs in mice. Results indicated that MPs accumulated in liver, kidney and gut, with a tissue-accumulation kinetics and distribution pattern that was strongly depended on the MPs particle size. In addition, analyses of multiple biochemical biomarkers and metabolomic profiles suggested that MPs exposure induced disturbance of energy and lipid metabolism as well as oxidative stress. Interestingly, blood biomarkers of neurotoxicity were also altered. Our results uncovered the distribution and accumulation of MPs across mice tissues and revealed significant alteration in several biomarkers that indicate potential toxicity from MPs exposure. Collectively, our data provided new evidence for the adverse consequences of MPs.

“…For example, polychaete worms (Thompson et al 2004), copepods (Cole et al 2013), and tadpoles (Hu et al 2016 (Browne et al 2013) have also been reported. For example, a significant decrease of the predatory performance of the common goby (Pomatoschistus microps) and a significant inhibition of acetylcholinesterase (AChE) activity under simultaneous exposure to Cr(VI) and microplastics were found, whereas less inhibition was caused by microplastics alone, and no observed inhibition was caused by Cr(VI) alone (Luís et al 2015). For example, a significant decrease of the predatory performance of the common goby (Pomatoschistus microps) and a significant inhibition of acetylcholinesterase (AChE) activity under simultaneous exposure to Cr(VI) and microplastics were found, whereas less inhibition was caused by microplastics alone, and no observed inhibition was caused by Cr(VI) alone (Luís et al 2015).…”

“…Studies on combined effects of microplastics and toxic chemicals have also been carried out. For example, a significant decrease of the predatory performance of the common goby (Pomatoschistus microps) and a significant inhibition of acetylcholinesterase (AChE) activity under simultaneous exposure to Cr(VI) and microplastics were found, whereas less inhibition was caused by microplastics alone, and no observed inhibition was caused by Cr(VI) alone (Luís et al 2015). However, if there is a driving chemical gradient, which acts as a vector pointing to the direction of sorption behavior, ingestion of microplastics may lead to cleaning of the pollutants in organisms (Koelmans 2015).…”

Microplastics pollution has been documented in the global environment, including at sea, in freshwater and in atmospheric fallout. Ingestion of microplastics by multiple kinds of organisms has been reported and has received increasing attention, because microplastics not only act as a source of toxic chemicals but also a sink for toxic chemicals. To better understand the great concerns about microplastics and associated toxic chemicals potential exposed to the organisms ingesting the debris, we should know more about the occurrence, fate, and risks of microplastics in the environment. What we should do depends on this better understanding. Integr Environ Assess Manag 2017;13:476-482. © 2017 SETAC.
