The Guangdong-Hong Kong-Macao Greater Bay Area (GBA), a globally recognized major bay area with a large population and important livestock and aquaculture industries, is a key source of steroids in the environment. Therefore, understanding the contamination status and ecological risks of these substances in GBA is particularly crucial due to their potential impacts on aquatic biodiversity and ecosystem health. This study systematically quantified 28 steroids and their metabolites across six coastal regions in GBA. Ten and nine steroids were identified in coastal water and sediments with levels of < 0.054 −5.3 ng/L and 0.98 −9.3 ng/g, respectively, with natural steroids being the predominant contributors. Compared to water, steroids and their metabolites were more likely to accumulate in sediments. Steroid hydrophobicity and environmental parameters (pH, temperature and salinity) can affect their distribution in coastal environments. While minimal and low ecological risks currently posed by steroids were found in water, specific compounds, such as progesterone and testosterone, warrant closer scrutiny due to their high priority status in aquatic environments, as determined by factors including occurrence, persistence, bioaccumulation and ecotoxicity. These findings provide foundational insights into steroid contamination in GBA, contributing to the understanding of their environmental behavior and supporting future risk assessments for this ecologically vital area.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"197 ","pages":"Article 106973"},"PeriodicalIF":6.9,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple participating plants, multiple water quality indices, and practical IPWI configurations incorporating water reuse headers and regeneration units are considered together with technical and environmental constraints (e.g., treatment system performance and effluent discharge limits).

The design of the venting structure must account for the risk of dry ice blockage caused by CO<sub>2</sub> throttling and its effectiveness in alleviating overpressure in the main pipeline.

This study uses a one-dimensional throttling model to investigate the effects of various venting structures on pressure, temperature, and mass flow rate. An orthogonal experimental design is applied to quantitatively analyze and compare their impact on low temperature and mass flow rate. The results indicate that flow rate is the fundamental reason for the temperature drop before and after changing the throttle valve. Increasing the number of vent valves, reducing the opening of the final stage valve, and decreasing the diameter of the vent pipe will all raise the temperature of CO<sub>2</sub> within the venting structure. However, the cost of improving low-temperature conditions is to reduce the mass flow rate. Through orthogonal experiments, it has been determined that the diameter of the vent pipe has the most significant impact on the mass flow rate and the extent of temperature reduction, followed by the valve opening, and finally the length of the vent riser. Therefore, in practical operation, the diameter of the ventilation pipe should be carefully selected to balance the risks of low temperature and overpressure.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"196 ","pages":"Article 106962"},"PeriodicalIF":6.9,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143527344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
