Summary: The study investigated the biochemical composition of faecal waste from Chinook salmon and its potential as a marker for fish waste in the environment. It found that while some biochemical characteristics were conserved in the faeces, others showed variability. Differences in markers between feed and faeces could be used to distinguish between feed pollution and fish waste in the environment. The study also showed that the elemental composition of Chinook salmon waste is similar to other salmonid species.

Summary: A phosphogypsum stack in SW Spain releases acidic and contaminated leachates into the surrounding estuarine environment. Column experiments using alkaline reagents dispersed in an inert matrix showed high effectiveness in treating the leachates. Precipitation of phosphate and sulfate minerals helped control the solubility of contaminants. Standardized leaching tests classified the waste as hazardous according to EU regulations, but non-hazardous according to US legislation. The solids generated in the treatment systems could be a promising secondary source for calcite and/or phosphate.

Summary: The bias-corrected CMEPI estimates at the regional level as a whole increased by 5.20% during the period due to inferior technological change effects. Low-yield area with a smaller increase rate of technological change needs to be improved. Thus, decision-makers should urgently enhance efficiency change in places such as Hunan, Chongqing, and Jiangxi. Among the low-yield area, Jiangxi and Hubei must alter their path of technological change. Finally, greater attention should focus on promoting the catch-up effect for better regional synergy development.

Summary: As society transitions to low-carbon, renewable energy resources, the demand for metals and minerals is set to increase. Harnessing microbe-mineral-metal interactions may offer many opportunities to improve some mining practises and support the long-term sustainability of mining. New technologies are needed to improve exploration and mining strategies as easily exploitable, high-grade deposits become increasingly depleted.

Summary: The study evaluated long-term phosphorus retention efficiency in a pilot-scale constructed wetland system over nearly 8 years. Both Schoenoplectus californicus and Phragmites australis showed significant phosphorus removal efficiency, with factors such as phosphorus loading rate, hydraulic loading rate, and dissolved oxygen being correlated with long-term retention. Plant uptake of phosphorus increased with operational years, with warmer seasons showing higher efficiency in phosphorus uptake.

Summary: The objective of this review is to evaluate the performance of constructed wetlands in reducing antibiotic-resistant genes (ARGs) during sewage treatment. Statistical and correlation analyses were performed using published data to determine the influence of operational and design parameters on ARG reduction in constructed wetlands. The results show that constructed wetlands alone may not be optimal technologies for reducing ARGs, but combining them with advanced wastewater treatment technologies can enhance ARG reduction.

Summary: The aim of this study was to evaluate the impact of a saturated constructed wetland-microbial fuel cell system on dissolved oxygen gradient, electricity generation, and ammonium removal. The results showed that there was no significant difference in dissolved oxygen concentration between different zones of the wetland system, and the operating mode and vegetation had no significant effect on dissolved oxygen. Chemical oxygen demand and ammonium removal efficiencies were high, and the maximum power density was recorded in the wetland system without plants.

Summary: This study evaluated the removal or inactivation efficiency of different treatment technologies for Cryptosporidium sp. and Giardia sp. It was found that aerobic technologies had the best removal efficiency for Cryptosporidium sp., while technologies combining filtration with UV or chemical disinfection agents showed the greatest removal efficiency for Giardia sp. However, detecting and quantifying the infectious forms of these parasites in effluents remains a major concern.

Summary: Household water supply can have various environmental impacts related to energy and material consumption, waste generation, and other inputs and outputs needed for water treatment and distribution. These impacts depend on the consumption patterns of the population, considering different water sources. This study evaluates the environmental impacts of water supply from a production-consumption perspective using life cycle assessment (LCA) and a survey to identify household water usage and sources.

Summary: Nanoparticle emissions from transport are a major concern due to their high concentration and potential health risks. This paper reviews the different aerosol modes produced by various transport sources, such as road, shipping, aviation, and rail, and investigates their toxicity effects. It concludes that transport sources emit a large number of nanoparticles that can damage the respiratory tract, lungs, and other organs, leading to systemic toxicity.

Summary: This study examines the impact of different plant culture systems and seasonal variations on constructed wetlands. The results show that polycultures in wetlands reduce nutrient input, but have a greater global warming impact compared to monocultures. Seasonality also affects environmental performance, with better results observed in the cold season. These findings provide valuable insights for improving environmental performance and developing strategies for constructed wetlands.

Summary: This literature review summarizes toxicological and epidemiological studies of ultrafine particles (UFPs) from different transport modes, including vehicle exhaust, non-exhaust, shipping, aviation, and rail. The results suggest that particles from both fossil and biodiesel sources exhibit toxic effects, with impacts on the lung, cardiovascular system, and brain. Further research is needed to better understand the relative toxicity of UFPs from different transport modes and their implications for health risk assessment.

Summary: UV disinfection is cost-effective and easy to maintain for decentralized areas. Parameters such as suspended solids, water hardness, zeta potential, UV dose, residual chlorine level, and design flow rate significantly influence the reactivation of microorganisms in UV systems. Maintaining low transmittance requires the removal of suspended solids and reduction of water hardness. Controlling the zeta potential within the range of 0-5 mV prevents particle and bacterial aggregation. Determining the appropriate UV dose and maintaining a residual chlorine level of at least 0.5 mg/L are essential for effective disinfection and reducing the likelihood of reactivation. Optimizing the design flow rate of the UV system is also important.
