“…PP200 ( Figure 2C). To the best of our knowledge, the only other study that investigated the effect of PP leachates on a unicellular organism found a decrease in dinoflagellate photosynthesis (M'Rabet et al, 2018) after 1 day of exposure, in accordance with the reduced growth and oxygen production observed in the marine cyanobacteria Prochlorococcus following a 24h-long exposure to leachates of common plastic items (i.e. HDPE shopping bags and PVC matting; Tetu et al, 2019).…”

Plastic is one of the major sources of pollution in modern oceans. When in seawater, toxic plasticizers (the additives incorporated in plastic polymers during manufacturing processes) typically diffuse and accumulate in sediments and in benthic and pelagic organisms' tissues. These plastic leachates affect survival, behavior and metabolism of various marine metazoans, but little effort was placed in studying their effect on protists. In this contribution we monitored the short-term effect of polypropylene (PP) leachates at both environmentally realistic and chronic concentrations on Haynesina germanica locomotion and metabolism. We found that PP leachates has no lethal nor effects on this species activity. Taken together, these results suggest that benthic foraminifera may be more resistant than marine metazoans to plasticizers pollutants.

“…Unfortunately, most of the additives such as, bisphenol A, di-2-ethylhexyl phthalate, and heavy metal complexes are known to be toxic. [53,54] Thus, the additives leaching from MPs can also impose toxicity to biota and human. As previously mentioned, the relatively high specific surface area and small particle size of the MPs resulted in the adherence and accumulation of heavy metals [16] and POPs [17,18] on the surface of MPs, which then further migrate in the environment with MPs.…”

How to Build a Microplastics‐Free Environment: Strategies for Microplastics Degradation and Plastics Recycling

et al. 2022

Microplastics are an emergent yet critical issue for the environment because of high degradation resistance and bioaccumulation. Unfortunately, the current technologies to remove, recycle, or degrade microplastics are insufficient for complete elimination. In addition, the fragmentation and degradation of mismanaged plastic wastes in environment have recently been identified as a significant source of microplastics. Thus, the developments of effective microplastics removal methods, as well as, plastics recycling strategies are crucial to build a microplastics‐free environment. Herein, this review comprehensively summarizes the current technologies for eliminating microplastics from the environment and highlights two key aspects to achieve this goal: 1) Catalytic degradation of microplastics into environmentally friendly organics (carbon dioxide and water); 2) catalytic recycling and upcycling plastic wastes into monomers, fuels, and valorized chemicals. The mechanisms, catalysts, feasibility, and challenges of these methods are also discussed. Novel catalytic methods such as, photocatalysis, advanced oxidation process, and biotechnology are promising and eco‐friendly candidates to transform microplastics and plastic wastes into environmentally benign and valuable products. In the future, more effort is encouraged to develop eco‐friendly methods for the catalytic conversion of plastics into valuable products with high efficiency, high product selectivity, and low cost under mild conditions.

“…In this situation, amino acid content in single cells increased, which corresponded to the N. closterium treated with Cu 2+ and nano-Cu at high concentrations. As the concentration of toxic substances increased, algal cells' physiological function (such as photosynthesis and respiration) was further attenuated (Li et al 2019;Liu et al 2016;M'Rabet et al 2018). And the cells could no longer cope with heavy metals by changing the cell volume.…”

In this study, the effects of different copper’s forms, metal salt (Cu2+), nano-metal (nano-Cu) and nano-metal oxide (nano-CuO), were tested on two marine algae named Skeletonema costatum and Nitzschia closterium. During a 96-hour exposure to nanoparticles (NPs) and salt, cell number, Cu2+ concentration in the culture medium, morphology and intracellular amino acids was measured to assess the toxicity of those copper materials and the toxicity mechanism of NPs. It was found that the toxicity of Cu2+, nano-Cu and nano-CuO on marine phytoplankton decreased in order. The EC50 values of Cu2+ and nano-Cu for S. costatum and N. closterium ranged from 0.356 to 0.991 mg/L and 0.663 to 2.455 mg/L, respectively. Nano-Cu inhibited the growth of marine phytoplankton mainly by releasing Cu2+, however, nano-CuO mainly produced toxic effects on microalgae through the effect of NPs. The secretion of extracellular polymeric substances by microalgae could be another possible reason for nano-Cu and nano-CuO to impose implications for microalgae. S. costatum was more sensitive to copper than N. closterium. Cu2+, nano-Cu and nano-CuO all reduced the total output of algae-derived amino acids by affecting the growth of phytoplankton and per-cell amino acids. This manuscript is of important implications to fill the data gaps for nano-Cu and nano-CuO risk assessment on marine algae.
