“…The final analysis can be performed by various analytical techniques, such as GC/MS, GC/ECD, HPLC/MS, HPLC/UV, liquid scintillation counter, or spectrophotometer [4,6,24,30,[45][46][47][48][49]. An overview of the workflow from a sample preparation for the analytical technique is illustrated in Figure 1.…”

“…A summary of selected studies performed by HPLC is shown in Table 2. In most studies, chromatography was performed with a C-18 column, which captures nonpolar to intermediate polar TOrCs [22,28,34,38,48,67,[70][71][72][73][74][75][76]. Advantages of an HPLC analysis are that an individual separation of the individual molecules takes place and detailed results can be (re)produced [47,70,71].…”

“…Hence, if the analytical method requires a separation by filtration, such a limitation needs to be considered in the experimental design, especially for particles in the sub-micrometer range. Studies either did not report such limitations since the particles were either too big (>1 µm) to encounter the problem [9,30,39,48,76,77], or a filtration step was avoided, i.e., by negligible depletion solid phase extraction, the aqueous boundary layer permeation method, head space extraction techniques, or else [4,5,32,82].…”

Organic Contaminants and Interactions with Micro- and Nano-Plastics in the Aqueous Environment: Review of Analytical Methods

Micro- and nanoplastic particles are increasingly seen not only as contaminants themselves, but also as potential vectors for trace organic chemicals (TOrCs) that might sorb onto these particles. An analysis of the sorbed TOrCs can either be performed directly from the particle or TOrCs can be extracted from the particle with a solvent. Another possibility is to analyze the remaining concentration in the aqueous phase by a differential approach. In this review, the focus is on analytical methods that are suitable for identifying and quantifying sorbed TOrCs on micro- and nano-plastics. Specific gas chromatography (GC), liquid chromatography (LC) and ultraviolet-visible spectroscopy (UV-VIS) methods are considered. The respective advantages of each method are explained in detail. In addition, influencing factors for sorption in the first place are being discussed including particle size and shape (especially micro and nanoparticles) and the type of polymer, as well as methods for determining sorption kinetics. Since the particles are not present in the environment in a virgin state, the influence of aging on sorption is also considered.

“…Luo et al found that the release amount of additives reached a maximum in 24 h, but only the high content microplastics (>1.6 g/L) had a significant inhibitory effect on the algal cell photosynthesis [134]. Normally, the additives in plastics are relatively environmentally friendly, but it has to be noted that microplastics can absorb other more toxic pollutants in the environment [97,[135][136][137][138][139][140]. These chemicals can be desorbed at certain conditions, which may pose higher toxic risks to microalgae [141,142], which needs more investigation.…”

Recently, microplastics pollution has attracted much attention in the environmental field, as researchers have found traces of microplastics in both marine and terrestrial ecological environments. Here, we reviewed and discussed the current progress on microplastics pollution in the marine environment from three main aspects including their identification and qualification methods, source and distribution, and fate and toxicity in a marine ecosystem. Microplastics in the marine environment originate from a variety of sources and distribute broadly all around the world, but their quantitative information is still lacking. Up to now, there have been no adequate and standard methods to identify and quantify the various types of microplastics, which need to be developed and unified. The fate of microplastics in the environment is particularly important as they may be transferred or accumulated in the biological chain. Meanwhile, microplastics may have a high adsorption capacity to pollutants, which is the basic research to further study their fate and joint toxicity in the environment. Therefore, all the findings are expected to fill the knowledge gaps in microplastics pollution and promote the development of relative regulations.

：Microplastics are ubiquitous in various environmental media on a global scale, and can adsorb co-existing pollutants, especially organic pollutants, thus changing the environmental behavior and toxicity of pollutants; they can also promote the migration of pollutants in different media through adsorption/desorption. Influencing factors and mechanisms of adsorption between microplastics and organic pollutants are necessary information for a comprehensive assessment of the environmental risks of microplastics and organic pollutants. Due to the complexity of composition, structure and surface characteristics of microplastics and the diversity of co-existing organic pollutants, the interaction between them is very complex. Based on a review of the relevant literatures in recent years, the authors systematically summarized the current status of occurrence and migration of microplastic in environmental media, the influencing factors of microplastic adsorption of organic pollutants and their interaction mechanisms, with a view to providing useful references for the in-depth understanding of the environmental behavior and ecological risks of microplastics.
