Effect of LDPE and biodegradable PBAT primary microplastics on bacterial community after four months of soil incubation

Chengtao Li et al.

Summary: The study found that the amount of the biodegradable plastic PBAT used can affect the physical-chemical properties of soil and bacterial communities. Higher amounts of PBAT decrease the content of NO3--N and TP in the soil, while lower amounts of PBAT increase the diversity of soil bacterial communities.

Microplastic Addition Alters the Microbial Community Structure and Stimulates Soil Carbon Dioxide Emissions in Vegetable-Growing Soil

Bo Gao et al.

Summary: The addition of microplastics significantly influences soil carbon and nitrogen cycling as well as the structure of microbial communities, leading to an increase in carbon dioxide emissions while nitrous oxide emissions remain unchanged. This study also found alterations in various chemical components and microbial community structure in soil due to the presence of microplastics.

Nitrogen and oxygen isotopomeric constraints on the sources of nitrous oxide and the role of submarine groundwater discharge in a temperate eutrophic salt-wedge estuary

Wei Wen Wong et al.

Summary: Estuaries have been identified as sources of nitrous oxide (N2O) emissions, with various pathways potentially governing N2O oversaturation. This study used N2O isotopes to assess production pathways in a eutrophic groundwater-impacted salt-wedge estuary, finding unique isotope values in the deep aquifer, suggesting the influence of multiple processes and potentially unidentified production pathways. The study highlights the substantial role of submarine groundwater discharge and noncanonical denitrification pathways in controlling N2O production in estuarine and groundwater environments.

New insights into the vertical distribution and microbial degradation of microplastics in urban river sediments

Lihua Niu et al.

Summary: This study investigated the vertical distribution of microplastics and the bacterial community assemblages in urban river sediments. The results showed that microplastics and associated microbial communities have vertical profiles in river sediments. The indicative plastic-degrading bacteria significantly increased in abundance and centrality from shallow to deep layers, suggesting a primary role in the degradation of microplastics in deep sediments.

The microplastisphere: Biodegradable microplastics addition alters soil microbial community structure and function

Jie Zhou et al.

Summary: Research shows that adding polyhydroxyalkanoates (PHAs) can enhance the growth and activity of soil microbial communities, leading to higher enzymatic activity in the microplastic environment. Compared to untreated soil, soil treated with PHAs exhibits increased microbial diversity and altered bacterial community structure.

Long-Term Fertilization History Alters Effects of Microplastics on Soil Properties, Microbial Communities, and Functions in Diverse Farmland Ecosystem

Hong-Zhe Li et al.

Summary: Studies have shown that exposure to 0.2% polyethylene microplastics can impact soil pH, with effects varying depending on soil type and fertilization history; Long-term fertilization history can alter the effects of MPs on soil bacterial and fungal communities; MPs have a greater impact on soil ecosystems with lower microbial diversity and functional gene abundance.

Effects of microplastics on plant growth and arbuscular mycorrhizal fungal communities in a soil spiked with ZnO nanoparticles

Weiwei Yang et al.

Summary: The study found that different types of microplastics have varying effects on maize growth, with high doses of PLA potentially causing strong phytotoxicity and reducing biomass. ZnO nanoparticles had minimal effects on plant growth, but led to zinc accumulation in plants and an increase in soil pH. Both microplastics and ZnO nanoparticles influenced the composition and diversity of AM fungal communities.

Effects of biofilm colonization on the sinking of microplastics in three freshwater environments

Lingzhan Miao et al.

Summary: Microplastics have been frequently found in freshwater environments, raising concerns about their ecological effects, particularly the impact of biofilms on freshwater ecosystems. The colonization of microbes on microplastics alters their transport behavior, with biofouled microplastics showing increased sinking tendencies compared to pristine ones. This highlights the importance of studying how biofouling affects the sinking and distribution of microplastics in freshwater environments.

Plastics in the Earth system

Aron Stubbins et al.

Summary: Plastic pollution has become a global issue, prompting us to consider plastics as emergent geomaterials never before seen in Earth's history. With high carbon content, plastics can rival natural organic carbon in some ecosystems, prompting geochemists to include plastics in their analyses to expedite understanding of plastics in the Earth system. Furthermore, plastics can serve as global-scale tracers to advance Earth system science.

The global threat from plastic pollution

Matthew MacLeo et al.

Summary: Plastic pollution that accumulates and is poorly reversible in the environment can have significant negative impacts such as changes to ecosystems, biological effects, and societal impacts. Therefore, a global response is needed to rapidly reduce plastic emissions through reductions in consumption of virgin plastic materials and internationally coordinated waste management strategies.

Comprehensive analysis of microbial dynamics linked with the reduction of odorous compounds in a full-scale swine manure pit recharge system with recirculation of aerobically treated liquid fertilizer

Yu-Na Jang et al.

Summary: Recirculating aerobically treated liquid fertilizer to a manure-pit recharge system is believed to reduce odorous materials generated during storage. Beneficial microorganisms were successfully established in the system, resulting in lower amounts of undesirable chemical components and odorous compounds compared to conventional manure slurry pits. This study comprehensively analyzed microbial dynamics related to the reduction of odorous compounds in response to recirculation of ATLF in the full-scale PRS.
