A majority of American adults report having used sex toys, which, by design, interact with intimate and permeable body parts yet have not been subject to sufficient risk assessment or management. Physical and chemical data are presented examining potential risks associated with four types of currently available sex toys: anal toy, beads, dual vibrator, and external vibrator. A standardized abrasion machine made real-time breakdown of products into microplastics and nanoplastics. The microplastics from the sex toys were then solvent extracted and analyzed using GC-MS. Rates of microplastics and nanoplastics released during abrasion testing from most microplastic release to least was the anal toy, beads, dual vibrator, external vibrator. Both micro- and nanoplastics particles were generated following the abrasion test, with the 50 percentile diameters (D50) ranging from the anal beads at 658.5 μm, dual vibrator at 887.83 μm, anal toy at 950 μm, and external vibrator at 1673.33 μm. The material matrix of each product was analyzed using ATR-FTIR, with results identifying the anal toy as polyethylene terephthalate (PET), the anal beads as polyvinyl chloride (PVC), the external vibrator as a silicone blend (polydimethylsiloxane [PDMS]), and the dual vibrator as a rubber mixture (polyisoprene). After extraction, phthalates known to be endocrine disruptors were present in all tested sex toys at levels exceeding hazard warnings. Analogous findings have been reported for similar materials that, when incorporated into other product categories, are subject to regulatory scrutiny in both the US and EU. This data set is not intended to be representative of sex toys as an entire class of products, nor are the abrasion experiments claiming to simulate exact use conditions. However, these exploratory data frame potential concerns, highlighting research questions and the need for prompt prioritization of protective action. Therefore, future studies and multi-stakeholder action are needed to understand and reduce risk for this class of products.

大多数美国成年人报告说他们使用过性玩具,这些性玩具的设计是与亲密和可渗透的身体部位相互作用,但却没有经过充分的风险评估或管理。物理和化学数据显示了与四种目前可用的性玩具相关的潜在风险:肛门玩具,珠子,双振动器和外部振动器。标准化的研磨机将产品实时分解为微塑料和纳米塑料。然后对性玩具中的微塑料进行溶剂提取和气相色谱-质谱分析。磨耗试验中微塑料和纳米塑料的释放量由多到少依次为肛门玩具、微珠、双振动器、外振动器。磨擦试验产生的微塑料和纳米塑料颗粒的50百分位直径(D50)分别为:肛门微珠(658.5 μm)、双振动器(887.83 μm)、肛门玩具(950 μm)和外振动器(1673.33 μm)。利用ATR-FTIR对每种产品的材料基体进行分析,结果确定肛门玩具为聚对苯二甲酸乙二醇酯(PET),肛门珠为聚氯乙烯(PVC),外振子为有机硅混合物(聚二甲基硅氧烷[PDMS]),双振子为橡胶混合物(聚异戊二烯)。提取后,所有测试的性玩具中已知的邻苯二甲酸酯是内分泌干扰物,其含量超过了危害警告。类似的材料也有类似的发现,当被纳入其他产品类别时,这些材料在美国和欧盟都受到监管审查。本数据集不打算代表性玩具作为一个完整的产品类别,也不是磨损实验声称模拟确切的使用条件。然而,这些探索性数据提出了潜在的问题,突出了研究问题和迅速确定保护行动优先次序的必要性。因此,需要未来的研究和多方利益相关者的行动来了解和降低这类产品的风险。补充资料:在线版本包含补充资料,下载地址:10.1186/s43591-023-00054-6。

Although (micro)plastic contamination is a worldwide concern, most scientific literature only restates that issue rather than presenting strategies to cope with it. This critical review assembles the current knowledge on policies and responses to tackle plastic pollution, including peer-reviewed scientific literature, gray literature and relevant reports to provide: (1) a timeline of policies directly or indirectly addressing microplastics; (2) the most up-to-date upstream responses to prevent microplastics pollution, such as circular economy, behavioral change, development of bio-based polymers and market-based instruments as well as source-specific strategies, focusing on the clothing industry, tire and road wear particles, antifouling paints and recreational activities; (3) a set of downstream responses tackling microplastics, such as waste to energy, degradation, water treatment plants and litter clean-up strategies; and examples of (4) multifaceted responses focused on both mitigating and preventing microplastics pollution, e.g., approaches implemented in fisheries and aquaculture facilities. Preventive strategies and multifaceted responses are postulated as pivotal to handling the exacerbated release of microplastics in the environment, while downstream responses stand out as auxiliary strategies to the chief upstream responses. The information gathered here bridges the knowledge gaps on (micro)plastic pollution by providing a synthesized baseline material for further studies addressing this environmental issue.
尽管(微)塑料污染是一个全球关注的问题,但大多数科学文献只是重申了这个问题,而不是提出应对它的策略。这篇重要的综述汇集了当前关于解决塑料污染的政策和对策的知识,包括同行评议的科学文献、灰色文献和相关报告,以提供:(1)直接或间接解决微塑料问题的政策时间表;(2)防止微塑料污染的最新上游对策,如循环经济、行为改变、生物基聚合物和市场化工具的发展以及特定来源的策略,重点是服装行业、轮胎和道路磨损颗粒、防污涂料和娱乐活动;(3)针对微塑料的一系列下游应对措施,如废物转化为能源、降解、水处理厂和垃圾清理策略;(4)侧重于减轻和预防微塑料污染的多方面应对措施的例子,例如,在渔业和水产养殖设施中实施的方法。预防策略和多方面的应对措施被认为是处理环境中微塑料加剧释放的关键,而下游应对措施作为主要上游应对措施的辅助策略脱颖而出。这里收集的信息通过为解决这一环境问题的进一步研究提供综合基线材料,弥补了关于(微)塑料污染的知识差距。

Microplastic pollution is a problem not only in the marine environment but also in freshwater ecosystems. Water flea (Daphnia magna) is one of the most common omnivorous cladocerans in freshwater ecosystems. In this study, the potential effects of microplastics (fluorescent polystyrene beads with dimensions of 6 microns) on the survival, growth and reproduction of Daphnia magna were examined during 21 days of laboratory experiments. Microplastics (MPs) were observed to be ingested alone or along with either the microalgae Chlorella vulgaris (Cv) or baker’s yeast (By). D. magna fed exclusively with microplastics showed a drastic decline in survival similar to that in the starving group. The least growth in total length or width was observed in Daphnia specimens fed only MPs and the starved groups. Daphia fed with a mixture of MPs/Cv or MPs/By produced a significantly (p < 0.05) lower number of ephippia. Our results show that high concentrations of microplastics adversely affect Daphnia magna populations.
微塑料污染不仅是海洋环境的问题,也是淡水生态系统的问题。水蚤(Daphnia magna)是淡水生态系统中最常见的杂食性支海动物之一。本研究通过21天的室内实验,考察了微塑料(尺寸为6微米的荧光聚苯乙烯珠)对大水蚤(Daphnia magna)存活、生长和繁殖的潜在影响。观察到微塑料(MPs)单独或与微藻小球藻(Cv)或面包酵母(By)一起摄入。专门喂食微塑料的大鼠的存活率急剧下降,与饥饿组相似。仅饲喂MPs组和饥饿组水蚤的总长度和总宽度增长最小。MPs/Cv和MPs/By的混合饲料显著(p < 0.05)降低了水蚤的鳞数。我们的研究结果表明,高浓度的微塑料会对大水蚤种群产生不利影响。

The composition, abundance and distribution of macroplastics (MAPs) and microplastics (MPs) in the Vinces and Los Tintos rivers were determined in three sites (Pueblo Nuevo, Santa Marianita, Los Tintos) from the low basin in the coastal province of Guayas, Ecuador. MAPS were recorded by visual census, covering a total distance of 140 m, and MPs were extracted in the intertidal sediments via density separation using a saturated NaCl solution, and these were counted using a stereomicroscope. A total of 940 plastic items were identified. The predominant debris was plastic with 85.2%, followed by manufactured materials and metals. The Vinces River contained the highest abundance of plastic in the locality of Pueblo Nuevo. The most abundant plastic was MPs. The most common MAPs were plastic bags (23%), food packaging (17%) and foamed plastic (8%). MP size classes quantified between 0.15 and 2.52 mm in intertidal, very fine sandy sediment and decreased in abundance with increasing grain size. The most common MPs were fibres (65.2%) (black (43.8%) and blue (25.8%)), and their distribution has a high correlation with population density and water flow direction: Santa Marianita 5.55 g−1, Pueblo Nuevo 7.39 g−1, Los Tintos 8.17−1. A significant abundance of fibres was identified in Pueblo Nuevo. The plastic spatial distribution revealed major plastic pollution in areas where recreational and tourism activities have been developed. Therefore, we recommend implementing awareness campaigns by educating businesses, residents and tourists on managing solid waste (especially plastic) and wastewater. Our results can serve as a baseline for future plastic monitoring in the area.
在厄瓜多尔瓜亚斯省沿海低洼盆地的三个地点(普韦布洛新埃沃、圣玛丽安娜塔、洛斯廷托斯)测定了文斯河和洛斯廷托斯河中宏观塑料(MAPs)和微塑料(MPs)的组成、丰度和分布。用目测法记录总距离为140 m的map,用饱和NaCl溶液进行密度分离提取潮间带沉积物中的MPs,并用体视显微镜进行计数。共鉴定出940件塑料制品。主要的垃圾是塑料,占85.2%,其次是人造材料和金属。在新普韦布洛地区,文斯河的塑料含量最高。最丰富的塑料是MPs。最常见的map是塑料袋(23%)、食品包装(17%)和泡沫塑料(8%)。潮间带、极细砂质沉积物的MP粒度分级在0.15 ~ 2.52 mm之间,丰度随着粒度的增加而减少。最常见的MPs是纤维(65.2%)(黑色(43.8%)和蓝色(25.8%)),它们的分布与人口密度和水流方向高度相关:Santa Marianita 5.55 g−1,Pueblo Nuevo 7.39 g−1,Los Tintos 8.17−1。在新普韦布洛发现了大量的纤维。塑料的空间分布表明,在娱乐和旅游活动发达的地区,塑料污染主要存在。因此,我们建议开展宣传活动,教育企业、居民和游客如何管理固体废物(特别是塑料)和废水。我们的研究结果可以作为该地区未来塑料监测的基线。

State of the Art Offshore In Situ Monitoring of Microplastic 海洋微塑料原位监测技术现状
Pub Date : 2022-11-02 DOI: 10.3390/microplastics1040044
D. Calore, N. Fraticelli
Microplastics make up a significant amount of the overall quantity of plastic debris that is present in seawater. However, their detection and monitoring at sea is cost-inefficient and challenging; typically, it consists of water sampling with special manta nets, followed by long (i.e., weeks) laboratory analysis to obtain valid results. The analysis of the state-of-the-art technologies capable of monitoring/detecting microplastics in the sea (typically in coastal areas) presented in this paper shows that there are currently no specific tools to obtain quick measurements. The classic multiparametric probes are useless and the contribution of their relative chemical–physical parameters to determine the presence of microplastics in water is insignificant. The evolution in the last decade of hardware and software tools for capturing hologram images and related post-processing seems to be one of the most effective methods available currently for the rapid detection of microplastics in seawater. In particular, some results of monitoring campaigns carried out in the Adriatic Sea using this type of technology are reported. The acquired data are analyzed and discussed, highlighting their strengths and weaknesses, with indications of the possible methodologies that could be used to improve these systems.
微塑料占海水中塑料碎片总量的很大一部分。然而,它们在海上的探测和监测成本低且具有挑战性;通常,它包括用特殊的蝠鲼网进行水样取样,然后进行长时间(即数周)的实验室分析以获得有效的结果。本文对能够监测/检测海洋(通常在沿海地区)微塑料的最先进技术的分析表明,目前没有特定的工具来获得快速测量。经典的多参数探针是无用的,它们的相对化学-物理参数对确定水中微塑料存在的贡献是微不足道的。在过去十年中,用于捕获全息图像和相关后处理的硬件和软件工具的发展似乎是目前可用于快速检测海水中微塑料的最有效方法之一。特别报告了在亚得里亚海使用这种技术进行的监测运动的一些结果。对获得的数据进行分析和讨论,突出其优点和缺点,并指出可用于改进这些系统的可能方法。

The acquired data are analyzed and discussed, highlighting their strengths and weaknesses, with indications of the possible methodologies that could be used to improve these systems.","PeriodicalId":74190,"journal":{"name":"Microplastics and nanoplastics","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83053640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microplastics have become a topic of considerable concern and intensive study over the past decade. They have been found everywhere in the oceans, including the deepest trenches and remotest parts of the Arctic. They are ingested by many animals and some are incorporated into tissues. There is considerable effort in studying what effects they have on marine life. It has become clear that when water samples are collected in ways that prevent most long thin particles from escaping through pores of a net, the most abundant type of microplastics found in water and sediments are microfibers (fibers with dimensions less than 5 mm). The major source of these pollutants is synthetic textiles, such as polyester or polyamides, which shed microfibers during their entire life cycle. Microfibers are released during textile manufacturing, everyday activities (e.g., washing, drying, wearing) and final disposal. The complexity of microfiber release mechanisms and of the factors involved make the identification and application of ways to reduce the inputs of microfibers very challenging. A comprehensive approach is strongly needed, taking into account solutions at a number of levels, such as re-engineering textiles to minimize shedding, applying washing machine filters, developing advanced wastewater treatment plants and improving the management of textile wastes. To harmonize and make mandatory the solutions identified, a variety of potential government policies and regulations is also needed.
在过去的十年中,微塑料已经成为一个备受关注和深入研究的话题。它们在海洋中随处可见,包括最深的海沟和北极最偏远的地区。它们被许多动物摄入,有些被组织吸收。人们在研究它们对海洋生物的影响方面付出了相当大的努力。很明显,如果收集水样的方法是防止大多数长而细的颗粒从网孔中逸出,那么在水和沉积物中发现的最丰富的微塑料类型是微纤维(尺寸小于5毫米的纤维)。这些污染物的主要来源是合成纺织品,如聚酯或聚酰胺,这些纺织品在其整个生命周期中都会脱落微纤维。微纤维在纺织品制造、日常活动(如洗涤、干燥、穿着)和最终处理过程中释放出来。由于超细纤维释放机制及其所涉及因素的复杂性,确定和应用减少超细纤维输入的方法非常具有挑战性。迫切需要采取综合办法,考虑到若干层面的解决办法,例如重新设计纺织品以尽量减少脱落、使用洗衣机过滤器、发展先进的废水处理厂和改进对纺织废料的管理。为了协调和强制执行所确定的解决方案,还需要各种潜在的政府政策和法规。

Opening Space for Plastics—Why Spatial, Soil and Land Use Data Are Important to Understand Global Soil (Micro)Plastic Pollution 为塑料打开空间——为什么空间、土壤和土地利用数据对了解全球土壤(微)塑料污染很重要

After five years of research on microplastic pollution of soils it becomes obvious that soil systems act as a reservoir for microplastics on global scales. Nevertheless, the exact role of soils within global microplastic cycles, plastic fluxes within soils and environmental consequences are so far only partly understood. Against the background of a global environmental plastic pollution, the spatial reference, spatial levels, sampling approaches and documentation practices of soil context data becomes important. Within this review, we therefore evaluate the availability of spatial MP soil data on a global scale through the application of a questionnaire applied to 35 case studies on microplastics in soils published since 2016. We found that the global database on microplastics in soils is mainly limited to agricultural used topsoils in Central Europe and China. Data on major global areas and soil regions are missing, leading to a limited understanding of soils plastic pollution. Furthermore, we found that open data handling, geospatial data and documentation of basic soil information are underrepresented, which hinders further understanding of global plastic fluxes in soils. Out of this context, we give recommendations for spatial reference and soil context data collection, access and combination with soil microplastic data, to work towards a global and free soil microplastic data hub.
经过五年对土壤微塑料污染的研究,土壤系统在全球范围内显然是微塑料的储存库。然而,迄今为止,土壤在全球微塑料循环中的确切作用、土壤中的塑料通量和环境后果只是部分了解。在全球环境塑料污染的背景下,土壤背景数据的空间参考、空间水平、采样方法和文献实践变得非常重要。因此,在这篇综述中,我们通过对2016年以来发表的35个土壤微塑料案例研究的问卷调查,评估了全球范围内空间MP土壤数据的可用性。我们发现,全球土壤微塑料数据库主要局限于中欧和中国的农业表层土壤。全球主要地区和土壤区域的数据缺失,导致对土壤塑料污染的了解有限。此外,我们发现开放数据处理、地理空间数据和基本土壤信息文献的代表性不足,这阻碍了对全球土壤塑性通量的进一步了解。在此背景下,我们提出了空间参考和土壤背景数据收集、获取和结合土壤微塑料数据的建议,以努力建立一个全球和自由的土壤微塑料数据中心。
