COVID-19 Pandemic Repercussions on the Use and Management of Plastics

Environmental Science & Technology, Год журнала: 2020, Номер 54(13), С. 7760 - 7765

Plastics are essential in society as a widely available and inexpensive material. Mismanagement of personal protective equipment (PPE) during the COVID-19 pandemic, with monthly estimated use 129 billion face masks 65 gloves globally, is resulting widespread environmental contamination. This poses risk to public health waste vector for SARS-CoV-2 virus, which survives up 3 days on plastics, there also broad impacts ecosystems organisms. Concerns over role reusable plastics vectors virus contributed reversal bans single-use highly supported by plastic industry. While not underestimating importance prevention transmission, it imperative undermine recent progress made sustainable plastics. There need assess alternatives that allow reductions PPE reinforce awareness proper disposal. Finally, assessment contamination driven pandemic will be required once outbreak ends.

Microbiome differential abundance methods produce different results across 38 datasets

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Янв. 17, 2022

Identifying differentially abundant microbes is a common goal of microbiome studies. Multiple methods are used interchangeably for this purpose in the literature. Yet, there few large-scale studies systematically exploring appropriateness using these tools interchangeably, and scale significance differences between them. Here, we compare performance 14 differential abundance testing on 38 16S rRNA gene datasets with two sample groups. We test amplicon sequence variants operational taxonomic units (ASVs) Our findings confirm that identified drastically different numbers sets significant ASVs, results depend data pre-processing. For many number features correlate aspects data, such as size, sequencing depth, effect size community differences. ALDEx2 ANCOM-II produce most consistent across agree best intersect from approaches. Nevertheless, recommend researchers should use consensus approach based multiple to help ensure robust biological interpretations. Many available, but it lacks systematic comparison among authors groups, show results.

Marine Plastic Debris: A New Surface for Microbial Colonization

Environmental Science & Technology, Год журнала: 2020, Номер 54(19), С. 11657 - 11672

Опубликована: Сен. 4, 2020

Plastics become rapidly colonized by microbes when released into marine environments. This microbial community—the Plastisphere—has recently sparked a multitude of scientific inquiries and generated breadth knowledge, which we bring together in this review. Besides providing better understanding community composition biofilm development ecosystems, critically discuss current research on plastic biodegradation the identification potentially pathogenic "hitchhikers" Plastisphere. The Plastisphere is at interface between its surrounding milieu, thus drives every interaction that synthetic material has with environment, from ecotoxicity new links food webs to fate plastics water column. We conclude so far not shown communities starkly differ other inert surfaces, particularly true for mature assemblages. Furthermore, despite progress been made field, recognize it time take plastic–Plastisphere–environment interactions step further identifying present gaps our knowledge offering perspective key aspects be addressed future studies: (I) physical characterization biofilms, (II) inclusion relevant controls, (III) study different successional stages, (IV) use environmentally concentrations biofouled microplastics, (V) prioritization gaining mechanistic functional communities.

Marine Microbial Assemblages on Microplastics: Diversity, Adaptation, and Role in Degradation

Annual Review of Marine Science, Год журнала: 2019, Номер 12(1), С. 209 - 232

Опубликована: Июнь 21, 2019

We have known for more than 45 years that microplastics in the ocean are carriers of microbially dominated assemblages. However, only recently has role microbial interactions with marine ecosystems been investigated detail. Research this field focused on three main areas: (a) establishment plastic-specific biofilms (the so-called plastisphere); (b) enrichment pathogenic bacteria, particularly members genus Vibrio, coupled to a vector function microplastics; and (c) degradation environment. Nevertheless, relationships between microorganisms remain unclear. In review, we deduce from current literature, new comparative analyses, considerations adaptation concerning plastic microplastic particles should rather limited effects ecosystems. The majority growing seem belong opportunistic colonists do not distinguish natural artificial surfaces. Thus, pose higher risk life forms by potentially harboring bacteria. On other hand, represent recalcitrant substances insufficient support prokaryotic metabolism will probably be degraded any period time relevant human society. Because cannot remove ocean, proactive action regarding research alternatives strategies prevent entering environment taken promptly.

Oceanic Hitchhikers – Assessing Pathogen Risks from Marine Microplastic

Trends in Microbiology, Год журнала: 2020, Номер 29(2), С. 107 - 116

Опубликована: Авг. 13, 2020

As plastic debris in the environment continues to increase, an emerging concern is potential for microplastic act as vectors pathogen transport. With aquaculture fastest growing food sector, and contamination of shellfish increasingly demonstrated, understanding any risk transport associated with important this industry. However, there remains a lack detailed, systematic studies assessing interactions impacts that attachment human animal pathogens on may have. Here we synthesise current knowledge regarding these distinct microplastic-associated bacterial communities uptake pathways into bivalves, discuss whether they represent health threat, highlighting outstanding questions critical our safety.
