ClearMulti-omics reveals manure-borne doxycycline and fragmented oversized microplastics co-disrupt pak choi growth and amplify antibiotic resistance in agroecosystems
Using a multi-omics approach, researchers found that microplastics and the antibiotic doxycycline from livestock manure work together to stunt vegetable growth and spread antibiotic resistance genes in farm soil. The combined contamination reduced pak choi biomass by about 29% and significantly increased the spread of drug-resistant bacteria. This highlights how using manure as fertilizer on plastic-contaminated farmland could threaten both food production and the effectiveness of antibiotics.

The study reveals that the co-presence of antibiotics and microplastics in agricultural soils may create compounding negative effects on crop health.
Combined contamination of microplastic and antibiotic alters the composition of microbial community and metabolism in wheat and maize rhizosphere soil
A study found that when soil is contaminated with both microplastics and antibiotics together, the damage to wheat and maize seedlings is worse than from either contaminant alone, with increased root oxidative stress and disrupted soil bacterial communities. This combined contamination, common in agricultural soils treated with plastic mulch and livestock manure, could affect crop health and food quality.
The Individual and Combined Effects of Microplastics and Antibiotics on Soil Microbial Metabolic Limitation and Carbon Use Efficiency
Researchers tested how polyethylene microplastics, biodegradable polylactic acid microplastics, and the antibiotic oxytetracycline individually and together affect soil microbial metabolism. When microplastics and antibiotics were combined, they shifted the nutrient limitation of soil microbes from nitrogen to phosphorus and reduced the efficiency with which microbes use carbon. The study suggests that the combined presence of microplastics and antibiotics in agricultural soils could disrupt fundamental nutrient cycling processes.

Insight into combined pollution of antibiotics and microplastics in aquatic and soil environment: Environmental behavior, interaction mechanism and associated impact of resistant genes
This review examines the combined pollution created when microplastics absorb antibiotics in water and soil environments. Researchers found that microplastics can concentrate antibiotics on their surfaces, and this combination promotes the spread of antibiotic-resistant genes in microbial communities. The study highlights that the interaction between these two emerging pollutants may pose greater environmental and health risks than either one alone.
Potential environmental risks of field bio/non-degradable microplastic from mulching residues in farmland: Evidence from metagenomic analysis of plastisphere
Researchers analyzed the microbes living on biodegradable and conventional plastic mulch fragments in farm soil and found that both types harbored antibiotic resistance genes and disease-causing bacteria, including human pathogens. Surprisingly, the biodegradable plastic (PBAT/PLA) had a higher diversity and abundance of resistance genes than conventional polyethylene. This challenges the assumption that biodegradable plastics are always safer and raises concerns about antibiotic resistance spreading from farm microplastics.
