“…The energy of IR radiation excites a specific molecular vibration when interacting with a sample, which enables the measurement of characteristic IR spectra 22 . FTIR spectroscopy can also provide additional information on particles, such as intensity of oxidation 23 and level of degradation 24 . While ATR-FTIR is suitable for chemical identification of larger particles (>0.5 mm), micro ATR-FTIR spectroscopy can provide information on the chemical structure of particles <0.5 mm, as it combines the function of a microscope and an infrared spectrometer.…”

Microplastic pollution in the marine environment is a scientific topic that has received increasing attention over the last decade. The majority of scientific publications address microplastic pollution of the sea surface. The protocol below describes the methodology for sampling, sample preparation, separation and chemical identification of microplastic particles. A manta net fixed on an »A frame« attached to the side of the vessel was used for sampling. Microplastic particles caught in the cod end of the net were separated from samples by visual identification and use of stereomicroscopes. Particles were analyzed for their size using an image analysis program and for their chemical structure using ATR-FTIR and micro FTIR spectroscopy. The described protocol is in line with recommendations for microplastics monitoring published by the Marine Strategy Framework Directive (MSFD) Technical Subgroup on Marine Litter. This written protocol with video guide will support the work of researchers that deal with microplastics monitoring all over the world.

“…Quantitative estimates of meso-debris have been obtained by sieving beach samples, typically to a depth of approximately 50 mm, and sorting samples including the use of floatation in sea water (e.g. Ryan & Moloney 1990;McDermid & McMullen 2004). However, little attention has been paid to sampling design and statistical power.…”

Plastic debris has significant environmental and economic impacts in marine systems. Monitoring is crucial to assess the efficacy of measures implemented to reduce the abundance of plastic debris, but it is complicated by large spatial and temporal heterogeneity in the amounts of plastic debris and by our limited understanding of the pathways followed by plastic debris and its long-term fate. To date, most monitoring has focused on beach surveys of stranded plastics and other litter. Infrequent surveys of the standing stock of litter on beaches provide crude estimates of debris types and abundance, but are biased by differential removal of litter items by beachcombing, cleanups and beach dynamics. Monitoring the accumulation of stranded debris provides an index of debris trends in adjacent waters, but is costly to undertake. At-sea sampling requires large sample sizes for statistical power to detect changes in abundance, given the high spatial and temporal heterogeneity. Another approach is to monitor the impacts of plastics. Seabirds and other marine organisms that accumulate plastics in their stomachs offer a cost-effective way to monitor the abundance and composition of small plastic litter. Changes in entanglement rates are harder to interpret, as they are sensitive to changes in population sizes of affected species. Monitoring waste disposal on ships and plastic debris levels in rivers and storm-water runoff is useful because it identifies the main sources of plastic debris entering the sea and can direct mitigation efforts. Different monitoring approaches are required to answer different questions, but attempts should be made to standardize approaches internationally.

“…The transect position is repeated for each sampling date throughout the year. The high tide line was selected because it holds much more plastic left by the receding tide than other areas of the intertidal zone [7], [19]. The minimum width of the transect recommended in the literature [10] has been used, that is, a total of six 0.25 m 2 (50 cm x 50 cm) quadrants of surface sediment evenly distributed 10 m apart, such as the depicted in Fig.…”

“…For each size range, plastics were grouped into various categories: film, line, pellet, fragment or hard pieces, foam pieces [7]. This process has been carried out by carefully naked eye visual sorting and with help of magnifying glass for smaller pieces, mainly for the items that passed the smaller mesh size in the sieve (1.4 mm).…”

An approach to the spatial and temporal distribution of marine debris stranded on Las Canteras Beach is developed by means of surveys carried out during one year, along three transects located on the southern, northern, and central parts of the beach. Results evidence that debris stranded on the beach represent an almost permanent type of pollution, but with a large time variability in the number of items observed along the three transects, as well as in the type and origin of the debris collected at the different stretches of the beach.
