“…To date, samples assessing MPs in air have been collected using a variety of samplers which actively pump air across a range of flow rates (8-100 L/min). One study assessed the effect of sampling volume on MPs and found a statistically significant logarithmic relationship between sampling volume and MP abundance, predominantly driven by fibrous MPs [46]. Inter-sample variation (standard deviation) was observed to be reduced when sampling volume exceeded 72 m 3 .…”

“…Evidently the sample duration will vary depending on the flow rate of the sampler, the nature of the sample (e.g., if highly polluted or high organic content) and the research question (e.g., if interested in a specific activity and/or a specific time of day). Liu et al [46], however, recommend a sample volume of at least 70m 3 (approximately a 12 h sampling duration using a high volume sampler (100 L/min)), whilst 24 h is typical for a PM10 sample collected with a low-volume sampler (EN 12341). Sampling duration is not relevant to dust as it is collected in a cross-sectional manner, with the concentration normalised to mass.…”

Development of screening criteria for microplastic particles in air and atmospheric deposition: critical review and applicability towards assessing human exposure

et al. 2021

Over the last several years there has been an increase in studies reporting the presence of microplastic particles (MPs) in both indoor and outdoor air. Data reported reflect a variety of different types of air samples, which have helped to demonstrate the ubiquity of MPs in the atmosphere and their potential contribution to atmospheric particulate matter (PM). The relative quality of the data reporting on MPs in air has not been evaluated, but represents an important step towards improving our overall understanding of the human health implications in relation to inhalation exposure to MPs. Adopting recent approaches that have been proposed to assess the quality of data for those studies reporting concentrations in biota and water samples, we identify a suite of criteria used to screen studies reporting MPs in air for the purposes of evaluating their usefulness in assessing human exposure. Here we review and summarize data from 27 studies reporting MPs in various types of air samples and evaluate each of the studies against 11 separate criteria representing four main categories (sampling; contamination mitigation; sample purification / handling; characterization and application towards assessing human exposure). On average, studies scored 48.6% (range 18.2–81.8%) of the maximum score. Only one study received a positive score for all criteria, implying that there remains a need for future studies to consider strengthening implementation and reporting of QA/QC protocol. The most urgent areas requiring attention relate to the need for studies to avoid and verify background contamination and to strengthen the quantification of method recovery efficiencies. The majority of studies report data for particulates > 10 μm. Due to the associations between exposure to particles < 10 μm and human health effects, we recommend that prioritization efforts that develop standard protocols, based on existing air sampling methods capable of characterizing MPs < 10 μm are progressed.

“…The early effects of MPs on the body have been suggested to be mediated by the absorption or alteration of the digestive system [ 27 , 28 ], which is mainly based on ingestion exposure scenarios. Meanwhile, the possibility of respiratory exposure, such as lung inflammation [ 13 ], chronic respiratory effects [ 21 ], asthma, pneumothorax, alveolitis, chronic bronchitis, and pneumonia [ 29 ], were suggested. In addition, it has been suggested that the influx of MPs into the body may induce oxidative stress [ 18 , 30 ], metabolic disorders [ 26 ], gastrointestinal effects [ 28 ], and cancer [ 28 ] in the long term, although the actual health impact assessment has not been sufficiently conducted in these studies.…”

“…The environmental hazards of MPs can be considered similar to that of PMs in that there is no chemical definition. However, unlike PMs in which exposure is mainly inhalational, a study of the exposure routes of MPs must consider both inhalational exposure mechanisms [19][20][21] and ingestion-related exposure scenarios [22][23][24][25][26]. The possibility of exposure through ingestion was mainly considered and evaluated based on the intake of predators above the marine ecosystem in the food chain as well as the intake of mineral water or drinking water containing MPs.…”

This rapid systematic review aims to summarize studies of human exposure to microplastics (MPs) and their health effects. For the systematic literature review, we separately searched for review articles and original articles published from 2000 to 2019 in the PubMed, NDSL, KMBASE, and Cochrane databases. A total of 276 review articles and 475 original articles were independently evaluated and eligibility of each article was assessed by two researchers. Finally, 8 review articles and 13 original articles were selected for analysis. There was no standardized methodology for determining human exposure to MPs. Therefore, the size, shape, color, and chemical composition of MPs were considered as factors that affected human exposure to MP. We ascertained that human exposure to MPs occurs through two major routes: inhalation and ingestion. The general population can be exposed to MPs through the food chain, food, and mineral water. Thus, there are multiple scenarios for the exposure process. The only exposure marker in humans is the detection and measurement of MPs in feces. Health effects of human exposure to MPs include respiratory effects from inhalation, digestive effects from ingestion, oxidative stress, and cancer. However, there are few studies of the effects of MP exposure in the general population. Based on a systematic review, we propose a standardized methodology to identify various exposure scenarios to facilitate studies of human exposure to MPs and their health effects.

“…So that the losses caused by the abundance of plastic waste are very visible in the environment. A particular concern among plastic waste is microplastics due to their small size [1,2] . Microplastics are defined as small pieces of plastic smaller than five millimeters in size [3][4][5] Globally, the discharge of primary microplastics into the sea is estimated at 1.5 million/year [3] .…”

Plastic waste has become one of the most serious threats to the marine environment. Among the plastic waste of special concern is microplastic because of its small size. This study aimed to analyze the level of risk of microplastic exposure through fish consumption in communities in the coastal area of Tamasaju Village, North Galesong District, Takalar Regency. Microplastic abundance found as many as 18 particles, microplastic types found are the shape of a line or fiber with different color and size variations. Blue fiber dominates at 77.77%. The average microplastic concentration (C) in fish is 0.2 mg/kg. The respondents interviewed were 30 people and mostly fishermen. Average intake rate (R) ± 155 grams/day, Average frequency of exposure (FE) of fish consumption ± 190 days/year, Average duration of exposure (Dt) of fish consumption ± 39 years and. Average respondent's weight (Wb) ± 58 kg. The average Non-Carcinogenic Intake Rate in fish consumption is 0.004754 mg/kg/day and the average Carcinogenic Intake Rate in fish consumption is 0.009328 mg/kg/day. The results of calculations with one-way ANOVA obtained P-Value = 0.009867
