Objective: To investigate the environmental pollution of PCBs from the place where the disused transformers were taken apart.
Methods: Take town F as the high exposed district for investigating and the town P which 100 kilometres is away from the town F as the low exposed district. At the same time, take town DXG which is 500 kilometres away from town F as the district for contrast. It was random and stated to extract samples of piped water, farmland rice and eggs. Then, the exceed-mark-quantity detecting methods were used to detect the PCBs and TEOs level in these samples.
Results: The content of PCBs in the samples was different except for piped water. Thediversity of the PCBs level in the hen's eggs was the most significant, duck's eggs took second place and farmland was the least. The order of PCBs level in the samples was: hen' s eggs > duck's eggs > farmland > rice > river water ( stream) > piped water.
Conclusion: The content of PCBs in each sample from Town F was higher than town P and town DXG on different levels. So the industry of taking the disused transformer apart had caused pollution of local environment.

The recovery of valuable materials from spent lithium-ion batteries (LIBs) has experienced increasing demand in recent years. Current recycling technologies are typically energy-intensive and are often plagued by high operation costs, low processing efficiency, and environmental pollution concerns. In this study, an efficient and environmentally friendly dielectrophoresis (DEP)-based approach is proposed to separate the main components of "black mass" mixtures from LIBs, specifically lithium iron phosphate (LFP) and graphite, based on their polarizability differences.

With an increasing concentration of microplastics (MPs) in every biome, laboratories with a focus on creating histology slides from resin-embedded specimens could be partially responsible for expanding the emission of microscopic resinous particles into the environment. With current research elucidating harmful health impacts from MPs, releasing them incautiously is arguably unethical and, in the near future, plausibly illegal. The Orthopedic Bioengineering Research Laboratory (OBRL) is in Colorado, a state known not only for its natural beauty but also for its increasing number of legislative amendments aimed at reducing plastic pollution.

Plant microbiomes have a major influence on forest structure and functions, as well as tree fitness and evolution. However, a comprehensive understanding of variations in fungi along the soil-plant continuum, particularly within tree seedlings, under global warming is lacking. Here, we investigated the dynamics of fungal communities across different compartments (including bulk soil and rhizosphere soil) and plant organs (including the endosphere of roots, stems and leaves) of Schima superba seedlings exposed to experimental warming and drought using AccuITS absolute quantitative sequencing.

Frequent and severe occurrences of harmful algal blooms increasingly threaten human health by the release of microcystins (MCs). Urgent attention is directed toward managing MCs, as evidenced by rising HAB-related do not drink/do not boil advisories due to unsafe MC levels in drinking water. UV/chlorine treatment, in which UV light is applied simultaneously with chlorine, showed early promise for effectively degrading MC-LR to values below the World Health Organization's guideline limits.

Introduction: The conjugative transfer of antibiotic resistance genes (ARGs) mediated by plasmids occurred in different intestinal segments of mice was explored.
Methods: The location of ARG donor bacteria and ARGs was investigated by qPCR, flow cytometry, and small animal imaging. The resistant microbiota was analyzed by gene amplification sequencing.
