Trophic level transfer of microplastic: Mytilus edulis (L.) to Carcinus maenas (L.). (2013, background): “Positivelycharged nano-sized plastic particles adsorbed to the cellulose constituent of algae (Chlorella spp. and Scenedesmus spp.), which hindered photosynthesis and could affect the sustainability of marine food webs (Bhattacharya et al., 2010).”
Understanding How Microplastics Affect Marine Biota on the Cellular Level Is Important for Assessing Ecosystem Function: A Review (2019, background): “Adsorption was also observed in the colonial green algae Scenedesmus or seaweed Fucus vesiculosus (Bhattacharya et al. 2010; Gutow et al. 2016).”
Quantitative investigation of the mechanisms of microplastics and nanoplastics toward zebrafish larvae locomotor activity. (2017, background): “…Scenedesmus) by measuring ROS production and total antioxidant capacity methods, and current studies on microplastics and organic nanoparticles further verified this by determining antioxidants concentrations (Browne et al., 2013; Bhattacharya et al., 2010; Chen et al., 2014; Chen et al., 2016b).”
The physical impacts of microplastics on marine organisms: a review. (2013, background): “Bhattacharya et al. (2010) found the binding of plastic beads (20 nm) to the algal species Chlorella and Scenedesmus inhibited photosynthesis, potentially due to the physical blockage of light and air.”
A horizon scanning assessment of current and potential future threats to migratory shorebirds (2012, background): “Bhattacharya et al. (2010) demonstrated that the adsorption of nanoplastic impeded algal photosynthesis.”
Microplastics accumulate on pores in seed capsule and delay germination and root growth of the terrestrial vascular plant Lepidium sativum. (2019, background): “Similarly, a study on the algae Chlorella and Scenedesmus found that exposure to 20 nm polystyrene nanoparticles hindered photosynthesis, possibly by the limitation of light due to shading effects (Bhattacharya et al., 2010).”
(Nano)plastics in the environment - Sources, fates and effects. (2016, background): “…as barrier additives (von Moos, 2014), biocides (Bouwmeester et al., 2015), flame retardants (Wu et al., 2007) and electrostatic deposition agents (Bhattacharya et al., 2010a), among others, and are often combined with additives such as plasticizers, surfactants, pigments, dispersants,…”
Sorption of fluorescent polystyrene microplastic particles to edible seaweed Fucus vesiculosus (2018, methodology): “charged PS particles possess a higher binding affinity than negatively charged particles for the microalgae (Bhattacharya et al. 2010; Nolte et al. 2017).”
Toxic effects of microplastic on marine microalgae Skeletonema costatum: Interactions between microplastic and algae. (2017, background): “Bhattacharya et al. (2010) also considered adsorption of microplastic hindered algal photosynthesis, because light and air could be blocked by the plastic particles.”
Microplastics in the marine environment. (2011, background): “Data on the effects of plastic nanoparticles on marine flora and fauna (Bhattacharya et al., 2010; Brown et al., 2001) are limited.”
Microplastics in the Marine Environment: Distribution, Interactions and Effects (2015, background): “phytoplankton and zooplankton, could be a pathway into the food chain (Bhattacharya et al. 2010). Many species of zooplankton undergo a diurnal migration. Migrating zooplankton could be considered a vector of microplastic contamination to greater depths of the water column and its inhabitants, eithe”
