Microplastics have shape- and polymer-dependent effects on soil aggregation and organic matter loss – an experimental and meta-analytical approachAbstract Microplastics are a diverse and ubiquitous contaminant, a global change driver with potential to alter ecosystem properties and processes. Microplastic-induced effects in soils are manifold as microplastics differ in a variety of properties among which the shape is of special interest. Our knowledge is limited regarding the impact of various microplastic sh... ...

Characterizing microplastic hazards: which concentration metrics and particle characteristics are most informative for understanding toxicity in aquatic organisms?Abstract There is definitive evidence that microplastics, defined as plastic particles less than 5 mm in size, are ubiquitous in the environment and can cause harm to aquatic organisms. These findings have prompted legislators and environmental regulators to seek out strategies for managing risk. However, microplastics are also an incredibly diverse contaminant suit... ...

Microplastics: a multidimensional contaminant requires a multidimensional framework for assessing risk Abstract The global ubiquity and demonstrated toxicity of microplastics has led governments around the world to express the need for a risk assessment on microplastics. To conduct a risk assessment, scientists often draw upon frameworks from other contaminants, however we argue that microplastics are a unique pollutant and thus require a unique framework. Microplast... ...
Measuring impacts of microplastic treatments via image recognition on immobilised particles below 100 μmAbstract The treatment of samples for microplastic (MP) analysis requires purification steps that sufficiently reduce the non-MP content while preserving the targeted particles integrity. Besides their macromolecular structure this also encompasses their in situ numbers and sizes. However, any step of sample manipulation will come at a cost: particle loss, fragmenta... ...

Extraction and concentration of nanoplastic particles from aqueous suspensions using functionalized magnetic nanoparticles and a magnetic flow cell Abstract Although a considerable knowledge base exists for environmental contamination from nanoscale and colloidal particles, significant knowledge gaps exist regarding the sources, transport, distribution, and effects of microplastic pollution (plastic particles < 5 mm) in the environment. Even less is known regarding nanoplastic pollution (generally considered... ...
Protocol for the production of micro- and nanoplastic test materials Abstract Micro- and nanoplastics (MNP) are ubiquitous, but little is known about the risks they pose to human health. Currently available data are of limited use for developing relevant risk assessments due to poor quality control, the lack of a standardised approach to particle characterisation and environmental analysis, and the use of test materials that do not r... ...
Investigating the correlation between morphological features of microplastics (5–500 µm) and their analytical recovery Abstract As a direct result of laboratory sample manipulation required to identify microplastics (MPs) within a given matrix, some MPs are inevitably lost. The extent of this loss can be quite significant and varies greatly depending on the sample matrix, choice of protocol and target MPs in question. Defining analytical MP recovery is therefore a critical component... ...
Legacy oceanic plastic pollution must be addressed to mitigate possible long-term ecological impactsAbstract Scientific research over the past decade has demonstrated that plastic in our oceans has detrimental consequences for marine life at all trophic levels. As countries negotiate an international legally binding instrument on plastic pollution, the focus is on eliminating plastic emissions to the environment. Here, we argue that, while this endeavour is urgent... ...

Vai trò của Môi Trường: Những hiểu biết mới về việc chiết xuất, chuẩn bị và định lượng vi nhựa trong một nghiên cứu mesocosm nước ngọt Dịch bởi AI Tóm tắt Việc chiết xuất và đặc trưng hóa các vi nhựa thứ cấp, được hình thành qua sự tác động của môi trường, cần được cải tiến liên tục về độ chính xác và tính khả thi nhằm tạo ra các đánh giá về tiếp xúc và rủi ro liên quan đến vi nhựa một cách vững chắc. Hiện tại, có một sự thiếu hụt về các phương pháp chiết xuất và định lượng đáng tin cậy đối với các hạt vi nhựa... ...

Detection, counting and characterization of nanoplastics in marine bioindicators: a proof of principle study
Tập 1 - Trang 1-13 - 2021
Plastic particulates in the environment pose an increasing concern for regulatory bodies due to their potential risk to higher organisms (including humans) as they enter the food chain. Nanoplastics (defined here as smaller than 1 μm) are particularly challenging to detect and analyze at environmentally relevant concentrations and in biological matrices. The tunicate Ciona Robusta is an effective ......
