“…After filtration, 5 mL of 30% H 2 O 2 (Labkem, Spain) and 5 mL of 0.05 M Fe(II) (Labkem, Spain) of previously filtered solutions were added to the filtration system and left to react for 15 minutes at room temperature (20ºC) to remove biogenic organic matter, followed by filtration and washing with Elix® water (Prata et al 2020a). Then, a few drops (0.5 -1 mL) of 0.01 mg mL -1 of Nile Red in ethanol (Sigma-Aldrich, Germany) were added to cover the filter and left to react for 5 minutes, followed by washing with Elix® water (Prata et al 2020b). Filters were kept in closed clean glass Petri dishes, kept inside a cardboard box, and dried over the counter for a week.…”

“…There is an extensive list of published methods for isolating MPs from sediments. 4,5 The variety of published procedures reflect the unique challenges associated with isolating MPs from marine sediments. Differences in extraction and isolation procedures ultimately determine the ability of various MPs to be accurately recovered and quantified, resulting in a wide range of recovery efficiencies.…”

Plastic pollution in marine systems degrades over time through numerous weathering processes. Microplastics (MPs) are small (<1mm) plastic particles which pose potential threat to marine ecosystems. Identifying MPs in marine sediments is crucial for understanding their fate and effects on benthic communities. Many methods exist for the extraction of MPs from sediments, but procedural differences prevent meaningful comparisons across datasets. This method comparison examines the efficiency of five common methods for extracting MPs (40-710μm) from marine sediments. Known quantities of MPs (i.e., polyethylene, polystyrene, polyethylene terephthalate, polyvinyl chloride, and polypropylene) were spiked into two different sediment treatments (sand and silt). The MPs were extracted using five varying published methods and enumerated to demonstrate percent recovery. Findings determined that sediment matrix, MP properties, and extraction method all substantially affected the percent recovery of MPs from marine sediments. Average recoveries of spiked microplastics were between 0-87.4% and varied greatly by sediment type, microplastic, and method of extraction. In general, larger particle and lower density MPs were more effectively recovered. Marine sediments low in organic matter and with larger grain size (i.e., sand) also had higher percent recoveries of MPs. These findings support the need for method optimization and unified procedures when measuring environmental MP abundance in marine sediments.

“…Figure 4 shows the complex relationships that must be taken into account when estimating indoor exposure to microplastics. Some studies have attempted to carry out a risk assessment on this basis and under consideration of the available data [5, 14, 34c, 52, 66b,c, 73] . However, this has not yet been achieved convincingly.…”

Analyses of air and house dust have shown that pollution of the indoor environment with microplastics could pose a fundamental hygienic problem. Indoor microplastics can result from abrasion, microplastic beads are frequently added to household products and microplastic granules can be found in artificial turf for sports activities and in synthetic admixtures in equestrian hall litter. In this context, the question arose as to what extent particulate emissions of thermoplastic materials from 3D printing should be at least partially classified as microplastics or nanoplastics. The discussion about textiles as a possible source of indoor microplastics has also been intensified. This Minireview gives an overview of the current exposure of residents to microplastics. Trends can be identified from the results and preventive measures can be derived if necessary. It is recommended that microplastics and their additives be given greater consideration in indoor environmental surveys in the future.
