abstract = {The interaction of microplastic (MP) with marine organisms is crucial for understanding the significant effect that MP and its additives may have on marine environments. However, knowledge regarding the magnitude of these pollutants in the Eastern Mediterranean Sea and the tropical Red Sea is still scarce. Here we examined the levels of phthalate acid esters (PAEs) and MP in Herdmania momus and Microcosmus exasperatus sampled along the Mediterranean and Red Sea coasts of Israel. High levels of dibutyl phthalate (DBP) and bis (2‑ethylhexyl) phthalate (DEHP) were found in ascidians at the majority of sampling sites, and MP particles were found in ascidians at all sites. As efficient filter-feeders and being widely-distributed, invasive ascidians present fundamental opportunities for the environmental monitoring of microplastic and its additives worldwide. The high levels of pollutants revealed emphasize the need for further research into the magnitude and effects of MP and PAEs in these regions.},

abstract = {In the past few years, there has been a significant development in freshwater microplastic research. Pollution has been detected in lakes and rivers of several continents, but the number of papers is still marginal compared to the ones investigating marine environments. In this study, we present the first detection of microplastics (MPs) in Central and Eastern European (CEE) surface waters and, globally, the first detection in fish ponds. Samples were taken from different types of fish ponds and natural water bodies along a novel concept down to a particle size of 100 μm, then, after sample preparation, MPs were characterized using an FTIR microscope. 92% of the water samples contained MPs ranging from 3.52 to 32.05 particles/m3. MPs were detected in 69% of the sediment samples ranging from 0.46 to 1.62 particles/kg. Dominant abundance of polypropylene (PP) and polyethylene was shown in water and PP and polystyrene in sediment samples. First results also indicate that fish ponds may act as a deposition area for MPs.},

abstract = {Our understanding of the fate and distribution of micro- and nano- plastics in the marine environment is limited by the intrinsic difficulties of the techniques currently used for the detection, quantification, and chemical identification of small particles in liquid (light scattering, vibrational spectroscopies, and optical and electron microscopies). Here we introduce Raman Tweezers (RTs), namely optical tweezers combined with Raman spectroscopy, as an analytical tool for the study of micro- and nanoplastics in seawater. We show optical trapping and chemical identification of sub-20 μm plastics, down to the 50 nm range. Analysis at the single particle level allows us to unambiguously discriminate plastics from organic matter and mineral sediments, overcoming the capacities of standard Raman spectroscopy in liquid, intrinsically limited to ensemble measurements. Being a microscopy technique, RTs also permits one to assess the size and shapes of particles (beads, fragments, and fibers), with spatial resolution only limited by diffraction. Applications are shown on both model particles and naturally aged environmental samples, made of common plastic pollutants, including polyethylene, polypropylene, nylon, and polystyrene, also in the presence of a thin eco-corona. Coupled to suitable extraction and concentration protocols, RTs have the potential to strongly impact future research on micro and nanoplastics environmental pollution, and enable the understanding of the fragmentation processes on a multiscale level of aged polymers.},

abstract = {Microplastics (MPs) pollution has become a problem that affects all aquatic, atmospheric and terrestial environments in the world. In this study, we looked into whether MPs in seas and lakes reach consumers through table salt. For this purpose, we obtained 16 brands of table salts from the Turkish market and determined their MPs content with microscopic and Raman spectroscopic examination. According to our results, the MP particle content was 16–84 item/kg in sea salt, 8–102 item/kg in lake salt and 9–16 item/kg in rock salt. The most common plastic polymers were polyethylene (22.9%) and polypropylene (19.2%). When the amounts of MPs and the amount of salt consumed by Turkish consumers per year are considered together, if they consume sea salt, lake salt or rock salt, they consume 249–302, 203–247 or 64–78 items per year, respectively. This is the first time this concerning level of MPs content in table salts in the Turkish market has been reported.},

abstract = {Floods caused by heavy rain carry significant amounts of pollutants into marine environments. This study evaluates the effect of multiple floods that occurred in the northeastern Mediterranean region in Turkey between December 2016 and January 2017 on the microplastic pollution in the Mersin Bay. Sampling was repeated in four different stations both before and after the flood period, and it was determined that in the four stations, there was an average of 539,189 MPs/km2 before the flood, and 7,699,716 MPs/km² afterwards, representing a 14-fold increase. Fourteen different polymer types were detected in an ATR FT-IR analysis, eight of which were not found in samples collected before the floods. The most common polymer type was identified as polyethylene both pre- and post-flood. The mean particle size, which was 2.37 mm in the pre-flood period, decreased to 1.13 mm in the post-flood period. A hydrodynamic modeling study was implemented to hindcast the current structure and the spatial and temporal distributions of microplastics within the study area. In conclusion, heavy rain and severe floods can dramatically increase the microplastic levels in the sea.},

abstract = {Both macroplastic and microplastic contamination levels were assessed for the first time in a tropical river estuary system, i.e. the Saigon River, that traverses a developing South East Asian megacity, i.e. Ho Chi Minh City, Vietnam. The analysis of floating debris collected daily on the Nhieu Loc – Thi Nghe canal by the municipal waste management service shows that the plastic mass percentage represents 11–43%, and the land-based plastic debris entering the river was estimated from 0.96 to 19.91 g inhabitant−1 d−1, namely 350 to 7270 g inhabitant−1 yr−1. Microplastics were assessed in the Saigon River and in four urban canals by sampling bulk water for anthropogenic fiber analysis and 300 μm mesh size plankton net exposition for fragment analysis. Fibers and fragments are highly concentrated in this system, respectively 172,000 to 519,000 items m−3 and 10 to 223 items m−3. They were found in various colors and shapes with smallest size and surface classes being predominant. The macroplastics and fragments were mainly made of polyethylene and polypropylene while the anthropogenic fibers were mainly made of polyester. The relation between macroplastic and microplastic concentrations, waste management, population density and water treatment are further discussed.},

abstract = {Freshwater studies have mainly been adopting sampling methods from marine research, thus the most commonly used tool is the plankton or manta net, usually with a mesh size of 300 µm or 333 µm. There are certain conditions when application of these sampling systems is com- plicated onsmaller freshwater bodies. Also, the filtered water volume is not obviously defined (due to clogging) even if a flow meter is used. To avoid these difficulties, another sampling approach is needed. Thetechnique using a pump and a set of filters is more common during wastewater sampling than inlakes or rivers. Until now, only a few studies have presented sampling systems that were based on asubmersible or a jet pump, including stainless steel filters. We developed a mobile sampling system that has many benefits when it is applied in inland freshwaters. The size of the complete apparatus enables sampling from a smaller boat or from the shore as well. A jet pump is operated by an aggregator. A PVC hose with a brass foot valve including a 2 mm mesh size strainer is put right under the water surface and is connected to thepump. Water is filtered through a set of 10” stainless steel filter cartridges (variable mesh size) instainless steel housing. Water quantity is measured by a flowmeter precisely. To prevent clogging of the fine mesh size filter (60 im), we coupled two cartridges and put in a 300 im pre-filter. This system enables sampling of more than 2.000 L water even if the Secchi depth is no more than 10 cm (e.g. due to flood or plankton). Project no. KFI 16-1-2017-0477 has been implemented with the support provided by the Na- tional Research, Development and Innovation Fund of Hungary, financed under the ”Vallalati KFI 16” funding scheme.},

abstract = {The Black Sea has a high risk of plastic pollution given the high river discharge of several industrialized countries into this semi-enclosed sea. Here, for the first time, the occurrence and distribution of microplastics are reported for the Black Sea. Microplastics were assessed from zooplankton samples taken during two cruises along the south eastern coast of the Black Sea in the November of 2014 and February of 2015. In each cruise neuston samples were collected at 12 stations using a WP2 net with 200 μm mesh. Microplastics (0.2–5 mm) were found in 92% of the samples. The primary shapes were fibres (49.4%) followed by plastic films (30.6%) and fragments (20%), and no micro beads were found. Average microplastic concentration in November (1.2 ± 1.1 × 103 par. m−3) was higher than in February (0.6 ± 0.55 × 103 par. m−3). Reduced concentrations in February were possibly caused by increased mixing. The highest concentrations of microplastics were observed in offshore stations during November sampling. The heterogeneous spatial distribution (0.2 × 103–3.3 × 103 par. m−3 for all samples) and accumulation in some stations could be associated to transport and retention mechanisms linked with wind and the dynamics of the rim current, as well by different sources of plastic. There were no statistically significant differences in MP concentration between sampling stations and sampling periods (t-test, p < 0.05).The relatively high microplastic concentrations suggest that Black Sea is a hotspot for microplastic pollution and there is an urgency to understand their origins, transportation and effects on marine life.},
