PlasticDB: a database of microorganisms and proteins linked to plastic biodegradation

Database, Journal Year: 2022, Volume and Issue: 2022

Published: Jan. 1, 2022

Abstract The number of publications reporting putative plastic-degrading microbes and proteins is continuously increasing, necessitating the compilation these data development tools to facilitate their analysis. We developed PlasticDB web application address this need, which comprises a database microorganisms reported biodegrade plastics. Associated metadata, such as techniques utilized assess biodegradation, environmental source microbial isolate presumed thermophilic traits are also reported. Proteins in categorized according plastic type they degrade. Each protein structure has been predicted silico can be visualized or downloaded for further investigation. In addition standard functionalities, searching, filtering retrieving records, we implemented several analytical that accept inputs, including gene, genome, metagenome, transcriptomes, metatranscriptomes taxa table data. Users now analyze datasets presence species potential pathways from those species. Database URL:http://plasticdb.org.

Field measurements reveal exposure risk to microplastic ingestion by filter-feeding megafauna

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: Nov. 1, 2022

Abstract Microparticles, such as microplastics and microfibers, are ubiquitous in marine food webs. Filter-feeding megafauna may be at extreme risk of exposure to microplastics, but neither the amount nor pathway microplastic ingestion well understood. Here, we combine depth-integrated data from California Current Ecosystem with high-resolution foraging measurements 191 tag deployments on blue, fin, humpback whales quantify plastic rates routes exposure. We find that baleen predominantly feed depths 50–250 m, coinciding highest measured concentrations pelagic ecosystem. Nearly all (99%) is predicted occur via trophic transfer. predict fish-feeding less exposed than krill-feeding whales. Per day, a krill-obligate blue whale ingest 10 million pieces microplastic, while likely ingests 200,000 microplastic. For species struggling recover historical whaling alongside other anthropogenic pressures, our findings suggest cumulative impacts multiple stressors require further attention.

Animal exposure to microplastics and health effects: A review

Emerging contaminants, Journal Year: 2024, Volume and Issue: 10(4), P. 100369 - 100369

Published: May 14, 2024

Microplastic (MP) contamination has become a pervasive global issue, affecting terrestrial and aquatic environments, its potential health hazards are of widespread concern. This review examined the intricate relationship between animal exposure to MPs their effects, revealing that MP affects broad spectrum species across habitats. Crucially, interspecies differences in ingestion, accumulation, responses emerge as central themes arising from various factors, including feeding behavior, physiology, ecological niches. The implications multifarious; animals may suffer physical harm, endure chemical adsorbed contaminants, provoke inflammatory responses, undergo behavioral modifications. Chronic raises concerns about long-term consequences, ability adsorb transport chemicals for bioaccumulation pollutants within food webs. ramifications profound, impacting population dynamics, ecosystem processes. interplay underscores need interdisciplinary research unites fields such biology, ecology, chemistry, toxicology. Recognizing effects significant implications, particularly enter human chain through on risks.

A growing crisis for One Health: Impacts of plastic pollution across layers of biological function

Frontiers in Marine Science, Journal Year: 2022, Volume and Issue: 9

Published: Nov. 2, 2022

The global accumulation of plastic waste has reached crisis levels. diverse and multilayered impacts on biological health prompts an evaluation these effects from a One Health perspective, through which the complexity processes can be integrated more clearly understood. Plastic particles ranging nanometers to meters in size are found throughout every ecosystem Earth, deepest marine trenches highest mountains. affects all layers organization, molecular cellular organismal, community, ecosystem-levels. These not only mediated by physical properties plastics, but also chemical polymers, thousands additives combined with plastics during manufacturing, sorbed chemicals microbes that transported waste. Using framework we provide overview following themes: 1) ways across levels 2) how interact between biology, 3) what knowledge gaps exist understanding within scales. We propose potential solutions address this growing crisis, emphasis perspectives consider oneness animals, humans, environment.

Microplastics in marine mammal blubber, melon, & other tissues: Evidence of translocation

Environmental Pollution, Journal Year: 2023, Volume and Issue: 335, P. 122252 - 122252

Published: Aug. 2, 2023

Marine mammals consume large quantities of microplastic particles, likely via trophic transfer (i.e., through prey who have consumed plastic) and direct consumption from seawater or sediment. Microplastics been found in the stomachs, gastro-intestinal tracts, feces cetaceans pinnipeds. Translocation ingested microplastics has documented other organs several aquatic species, but not examined marine mammals. highly specialized lipid-rich tissues which may increase susceptibility to lipophilic microplastics. Here we demonstrate occurrence microplastics, ranging size, mass concentration, particle count concentration 24.4 μm - 1387 μm, 0.59 μg/g 25.20 μg/g, 0.04 0.39 particles/g, respectively, four (acoustic fat pad, blubber, lung, & melon) twelve mammal species inclusive mysticetes, odontocetes, phocids. Twenty-two individuals were for using a combination Raman spectroscopy pyrolysis gas chromatography with spectrometry. Overall, 68% had at least one tissue types, most common polymer shape observed being polyethylene fibers, respectively. These findings suggest some proportion translocate throughout bodies posing an exposure risk both people.
