Summary: The occurrence and distribution of typical estrogenic and androgenic steroid hormones in surface water from nine lakes in Wuhan City, China were investigated. The concentrations of these hormones varied widely among different lakes and showed significant positive correlations. The detection frequencies and abundance of steroids were higher in lakes located in residential areas. Anthropogenic factors were found to play a significant role in steroids contamination in urban surface water.

Summary: The complexity of waste management systems due to different waste management practices makes them difficult to analyze, but the System Dynamics approach helps in conceptualizing and evaluating these systems. By studying waste management practices in various countries, strategies can be developed to achieve goals such as expanding landfill life span and mitigating global warming. Increasing waste reduction, source separation, and recycling rates can decrease environmental impact, but may not always be economically profitable. Incentives for waste separation and knowledge about waste management consistently have a positive impact on the entire system.

Summary: Animal husbandry is the second largest source of steroid estrogen pollutants in the environment, and investigating the occurrence and fate of SEs discharged from concentrated animal feeding operations is significant. This research focused on a typical concentrated dairy farm in China and found high concentrations of SEs in slurry, lagoon water, and slurry-irrigated soil, with complex transport and accumulation patterns. Correlations and hierarchical clustering analysis revealed intertransformation among SEs and their correlation with various physicochemical indexes, highlighting the potential estrogenic risks posed by slurry irrigation and lagoon water discharge. Proper management practices are essential to control SE pollution effectively.

Summary: The study found that various pollutants were present in the groundwater and soil of the hazardous waste disposal center, with cadmium exceeding the risk screening value for soil contamination. After conducting a health risk assessment, it was found that under different reuse conditions, the non-carcinogenic and carcinogenic risks of soil pollutants to on-site workers and surrounding residents need to be addressed.

Summary: With the rapid growth of passenger cars in China, waste passenger car tires have become one of the fastest growing solid wastes. This study investigates the current disposal capacity of the pyrolysis method for waste passenger car tires and predicts the future total number of waste tires based on car growth rate and disposal capacity. Additionally, an evaluation of pyrolysis on 15 collected waste tires was conducted, revealing the limitations and the potential of a new pyrolysis technology.

Summary: The study investigated the removal of steroid hormones from mariculture systems using seaweeds, with Caulerpa lentillifera showing the highest efficiency. The removal of hormones by Caulerpa lentillifera was attributed to initial quick biosorption, slow accumulation, and biodegradation processes. The study also found a positive relationship between hormone removal and nutrient levels, as well as initial hormone concentrations.

Summary: This manuscript proposes an integrated system for treating hospital solid waste that can operate during normal and emergency situations. The benefits of integrating different hospital solid waste treatment systems with the existing incineration system were analyzed, with a focus on the thermal friction sterilization integration system. The results show that implementing the integrated incineration-frictional systems can lead to significant savings and better resource recovery.
