Microplastics (MP) are a contaminant of emerging concern and, as such, there has been rush to action and publication. Over the past two decades, this haste resulted in chaotic cluttered literature rife with inappropriate methodologies, poor experimental protocols, misinterpreted results, overstated significance, subsequent damaging media stories. This review provides critical assessment current scientific on interactions between particle-feeding molluscs MP their purported impacts (>750 publications), recommendations for future efforts. Experimental studies were critically assessed assigned scores ranging from 0 2 indicators veracity. The mean ratio 84 papers included analysis was 0.9, indicating that most publications contained too many flaws. It is not surprising have noted shellfish guts globally.

The toxicity of microplastics on Daphnia magna as a key model for freshwater zooplankton is well described. While several studies predict population-level effects based short-term, individual-level responses, only very few have validated these predictions experimentally. Thus, we exposed D. populations to irregular polystyrene and diatomite natural particle (both ≤63 μm) over 50 days. We used mixtures both types at fixed concentrations (50,000 particles mL-1) recorded the overall population size structure, individual animals, resting egg production. Particle exposure adversely affected structure induced terminal was 28-42 % lower in compared control populations. Interestingly, containing stronger than alone, highlighting that are not per se less toxic microplastics. Our results demonstrate an synthetic has negative zooplankton. Understanding mixture important given aquatic organisms will experience both. Just chemical pollutants, better knowledge such joint essential fully understand environmental impacts complex mixtures. ENVIRONMENTAL IMPLICATIONS: commonly considered hazardous effects, there dearth information how they affect Since latter understanding microplastics, investigated exposures magna. In addition, because neither occurs alone nature can be expected environmentally realistic scenario. show daphnid highlight mixture-toxicity designs one step towards more realism research.

Aquaculture is essential for meeting the growing global demand fish consumption. However, widespread use of plastic and presence microplastics in aquaculture systems raise concerns about their impact on health safety products. This study focused Nile tilapia (Oreochromis niloticus), one most important species globally. The aim this was to investigate effects dietary exposure a mixture four conventional fossil fuel-based polymers (microplastics) adult juvenile tilapia. Two experiments were conducted, with 36 (10- 40 g weight) exposed 30 days 24 (600- 1000 g) 7 days, former including natural particle (kaolin) treatment. In experiment, no significant intestinal (Ussing chamber method), oxidative stress, or inflammatory pathways (enzymatic genetic biomarkers) observed after microplastic mixture. alterations following mixture, indicating potential adverse health. These results highlight negative impacts economics aquaculture.
