Characterizing microplastic hazards: which concentration metrics and particle characteristics are most informative for understanding toxicity in aquatic organisms? Tập 2 Số 1
Leah M. Thornton Hampton, Susanne M. Brander, Scott Coffin, Matthew Cole, Ludovic Hermabessière, Albert A. Koelmans, Chelsea M. Rochman
AbstractThere 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 suite, comprising a
complex mixture o... hiện toàn bộ
Microplastics: a multidimensional contaminant requires a multidimensional framework for assessing risk
Kennedy Bucci, Chelsea M. Rochman
AbstractThe 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. Microplastics are a
multidimensional contam... hiện toàn bộ
Measuring impacts of microplastic treatments via image recognition on immobilised particles below 100 μm Tập 1 Số 1 - 2021
Robin Lenz, Kristina Enders, Franziska Fischer, Josef Brandt, Dieter Fischer, Matthias Labrenz
AbstractThe 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, fragmentation, coagulation or
degradation ... hiện toàn bộ
Investigating the correlation between morphological features of microplastics (5–500 µm) and their analytical recovery
Oskar Hagelskjær, A. Crézé, Gaël Le Roux, Jeroen E. Sonke
AbstractAs 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 in ensuring
the quality of MP pr... hiện toàn bộ
Protocol for the production of micro- and nanoplastic test materials
Luke Parker, Elena M. Höppener, Edward F. van Amelrooij, Sieger Henke, Ingeborg M. Kooter, Kalouda Grigoriadi, Merel G. A. Nooijens, Andrea M. Brunner, Arjen Boersma
AbstractMicro- 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 reflect those found in the
environ... hiện toàn bộ
Detection, counting and characterization of nanoplastics in marine bioindicators: a proof of principle study Tập 1 - Trang 1-13 - 2021
Andrea Valsesia, Jeremie Parot, Jessica Ponti, Dora Mehn, Rita Marino, Daniela Melillo, Shin Muramoto, Mike Verkouteren, Vincent A. Hackley, Pascal Colpo
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 ... hiện toàn bộ
Bringing sex toys out of the dark: exploring unmitigated risks Tập 3 Số 1
Joana Marie Sipe, Jaleesia D. Amos, Robert F. Swarthout, Amalia Turner, Mark R. Wiesner, Christine Ogilvie Hendren
AbstractA 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

Legacy oceanic plastic pollution must be addressed to mitigate possible long-term ecological impacts Tập 3 Số 1
Camille Richon, Karin Kvale, Laurent Lebreton, Matthias Egger
AbstractScientific 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 urgently needed to
limit the negative i... hiện toàn bộ
