The widespread application of herbicides has profound ecological consequences, particularly regarding the distribution antibiotic resistance genes (ARGs) and microbial communities. In this study, we analyzed herbicide-related metagenomic data to assess impact herbicide exposure on ARGs populations. Our results demonstrate that significantly increased abundance ARGs, those associated with multidrug resistance, sulfonamides, bacitracin, notable increases in subtypes such as bacA sul1. Microbial community analyses revealed a dominance Pseudomonadota Actinomycetota, along significant down-regulation genera like Fibrisoma, Gilsonvirus, Limnobacter, Wilnyevirus experimental group. Additionally, led marked reduction biodiversity. When threshold values were relaxed, correlation co-occurrence pattern between multiple sul1, suggesting horizontal gene transfer plays pivotal role spread herbicide-contaminated soils. Moreover, environmental factors found influence both composition ARG distribution. These findings highlight complex effects diversity dissemination genes, emphasizing need for further research into long-term public health implications use.

Microplastics (MPs) are omnipresent particles that receive special attention because of their persistent nature and potential impact on human disease the environment. Most MPs generated by degradation larger plastic items such as clothing, car tires, discarded materials. In indoor environments, where beings spend most time, aerial MP levels higher, majority fibers produced from textiles. Airborne indoors a greater danger to humans than ingested in food drink. Fragments small enough remain substantially suspended air column, airborne microparticles measured PM10 PM2.5, become available for assimilation through respiration, potentially producing various health problems. Larger act ingestion skin contact. can carry microorganisms micropollutants adsorbed surfaces, facilitating uptake survival within body. Indoor thus represent emerging pollutants fast-growing concern especially important invaders respiratory system, reaching alveoli lungs finally entering circulatory system other tissues. Since this direct exposure contamination via is so important, we discuss article ways which concentration dispersal be affected turbulence induced anthropogenic objects conditioners, filters, purifiers. Much evidence equivocal further research necessary.
