ClearMicroplastics Stress Alters Microorganism Community Structure and Reduces the Production of Biogenic Dimethylated Sulfur Compounds
Researchers studied how microplastic stress alters marine microbial community composition and affects production of dimethylsulfoniopropionate (DMSP) and dimethyl sulfide, which play key roles in global sulfur cycling and cloud formation. Microplastic exposure shifted microbial community structure and significantly reduced DMSP and DMS production, with potential implications for climate-relevant atmospheric sulfur emissions from the ocean.
Microplastics stress alters microorganism community structure and reduces the production of biogenic dimethylated sulfur compounds
This study examined how microplastic stress affects marine microbial community structure and the production of dimethylsulfoniopropionate (DMSP) and dimethyl sulfide (DMS) -- sulfur compounds that play key roles in global sulfur cycling and cloud formation. Microplastic exposure altered microbial community composition and significantly reduced DMSP and DMS production, indicating potential cascading effects on global climate-regulating biogeochemical cycles.
Effects of micro- and nano-plastics on community assemblages and dimethylated sulfur compounds production
Researchers conducted a field microcosm experiment to study how micro- and nanoplastics affect marine plankton communities and the production of climate-relevant sulfur compounds. They found that medium and high concentrations of polystyrene, polyethylene, and polyamide particles disrupted zooplankton grazing and altered the production of dimethyl sulfide. The study suggests that plastic pollution could interfere with marine biogeochemical cycles that play a role in climate regulation.

Researchers exposed a key ocean-dwelling algae species to polystyrene micro- and nanoplastics and found that both sizes impaired growth and triggered oxidative stress. The nanoplastics were more harmful than microplastics, reducing chlorophyll content and altering the production of climate-relevant sulfur compounds. The study suggests that plastic pollution could disrupt ocean algae that play an important role in regulating atmospheric chemistry and climate.

Size-dependent influences of nano- and micro-plastics exposure on feeding, antioxidant systems, and organic sulfur compounds in ciliate Uronema marinum
Researchers studied how nano- and microplastics of different sizes affect a marine ciliate that plays a key role in ocean sulfur cycling. Exposure to polystyrene particles reduced the organisms' ability to feed on algae, which in turn dramatically decreased their production of dimethyl sulfide, a gas important for climate regulation. The findings suggest that plastic pollution could disrupt fundamental ocean chemistry processes beyond its direct effects on individual organisms.

Researchers studied how microplastics and copper together affect Manila clams and their role in producing dimethyl sulfide, a compound that influences global climate. The study found that combined exposure to both pollutants increased oxidative stress in the clams and reduced their production of climate-relevant sulfur compounds, pointing to broader ecological consequences of ocean pollution.

This study investigated how microplastics affect sulfur cycling in coastal mangrove sediments, an important process for marine ecosystem health. Biodegradable plastics actually increased sulfur-related bacterial activity more than conventional plastics, suggesting they may have unintended environmental effects. The findings show that microplastic pollution can disrupt fundamental chemical cycles in coastal environments, which could have cascading effects on water quality and the marine food web.

This study used soil microcosm experiments to investigate how polystyrene and polyphenylene sulfide microplastics affect sulfur mineralization in different soil types, revealing mechanisms by which MPs alter soil physicochemical properties and microbial activity.
The impact of microplastics on sulfur REDOX processes in different soil types: A mechanism study
This study found that polystyrene and polyphenylene sulfide microplastics alter sulfur cycling processes in soil, changing how sulfur is converted between different chemical forms. The effects varied depending on soil type, with the most significant changes in sulfur availability occurring in black soil and paddy soil. Since sulfur is an essential nutrient for crops, microplastic contamination in farmland could subtly affect soil fertility and crop nutrition in ways that are not immediately visible.

Researchers conducted a 19-day experiment examining how nanoplastics and the antibiotic ofloxacin, alone and in combination, affect marine microbial communities and sulfur cycling in coastal seawater. Combined exposure produced significantly stronger negative effects than either pollutant alone, reducing microbial biomass, simplifying community networks, and disrupting the cycling of DMSP, a compound important for marine food webs and climate regulation.

[Effects of Polyethylene Microplastics on Growth and Halocarbon Release of Marine Microalgae].
Lab experiments showed that polyethylene microplastics affected two species of marine microalgae differently, inhibiting growth of one while promoting growth of the other. Microplastic stress also increased production of reactive oxygen species and altered the release of volatile halocarbons, trace gases important for climate and ozone chemistry.
Insight into the multifactorial effect of climate change on marine bacteria: resilience mechanisms and mitigation strategies
This review examines how multiple climate change factors — including ocean acidification, warming, deoxygenation, and anthropogenic pollutants including microplastics — interact to affect marine bacteria and their roles in biogeochemical cycling. The authors synthesize resilience mechanisms employed by marine bacteria and discuss mitigation strategies to preserve microbial ecosystem functions under accelerating environmental change.
Effects of nanoplastics exposure on ingestion, life history traits, and dimethyl sulfide production in rotifer Brachionus plicatilis
Researchers exposed tiny marine organisms called rotifers to polystyrene nanoplastics and found that the particles accumulated in their digestive tracts, shortened their lifespans, and reduced their ability to reproduce. Higher concentrations also decreased the production of dimethyl sulfide, a compound important for cloud formation and climate regulation. This study shows that nanoplastic pollution can affect marine organisms at the base of the food chain, with potential ripple effects on both ecosystems and the climate.
Nanoplastic–lipid interactions at marine relevant interfaces: implications for atmospheric chemistry
This study examined what happens when nanoplastics become incorporated into sea spray aerosols — the tiny droplets that burst into the air when waves break — finding that nanoplastics alter the structure and composition of the lipid films that coat these airborne droplets. Since these lipid layers influence how aerosols behave chemically in the atmosphere, nanoplastics could be subtly changing atmospheric chemistry and cloud formation in ocean regions. This is a relatively unexplored pathway by which plastic pollution may have broader environmental consequences beyond the ocean surface.
