This study reports the occurrence, distribution, and ecotoxicological risks of eight pyrethroids in sediments and biosolids from wastewater treatment plants (WWTPs) across Ireland. A total of 120 sediment samples were collected along with 3 biosolids samples from each of seven WWTPs (n = 21). The relative abundance of individual pyrethroids differed between sediment and biosolids samples. Permethrin, cyfluthrin, and cypermethrin were predominant in sediments, with cyfluthrin, permethrin and deltamethrin predominant in biosolids. Such disparities may reflect the anaerobic conditions and shorter residence times of biosolids within WWTPs compared to sediments, which may influence the extent of degradation of our target pyrethroids and drive differences in their relative abundance between biosolids and sediments. Pyrethroid concentrations in Irish sediments were generally within the global range. Among the four pyrethroids currently registered in Ireland (cypermethrin, esfenvalerate, deltamethrin, and λ-cyhalothrin), cypermethrin showed the highest concentrations in sediments, likely reflecting both agricultural, aquacultural, and indoor uses. Meanwhile, permethrin and cyfluthrin, although not registered for plant protection in Ireland, were also prevalent—permissible biocidal uses may explain the presence of permethrin, while cyfluthrin warrants further scrutiny. Risk quotient assessment of pyrethroid concentrations in Irish sediments, revealed that while bifenthrin and resmethrin posed low ecotoxicological risks, other pyrethroids such as permethrin, cyfluthrin, and cypermethrin presented moderate to high risk in many sediment samples. These findings highlight the widespread distribution and ecotoxicological risks associated with pyrethroid contamination in Ireland's aquatic environments, emphasising the need for continued monitoring and risk management strategies to mitigate their environmental impacts.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"995 ","pages":"Article 180108"},"PeriodicalIF":8.2,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Schizophrenia diagnosis is associated with more than double the all-cause mortality risk of the general population and a 13- to 15-year reduction in life expectancy, due to a myriad of intersecting factors and underlying causes. Persons with schizophrenia are particularly susceptible to the negative health effects of extreme heat, as demonstrated by the 2021 Western North America Heat Dome. During this event, schizophrenia was associated with a 3-fold increase in the odds of mortality in British Columbia, Canada, far surpassing the risks associated with other common heat-sensitive chronic conditions, including diabetes, hypertension, and heart disease. While individual factors such as age, presence of chronic disease, and medication-use can impair thermoregulation and limit a person's ability to sense and respond to heat, physiological and behavioural factors associated with schizophrenia can exacerbate these impairments. In-turn, social and community-level factors play important roles in aggravating or mitigating heat-health risks. However, to date, our understanding of the separate and combined influence of the physiological, behavioural, and social determinants underpinning heat-susceptibility in individuals with schizophrenia remains largely unresolved. We therefore conducted a critical review to examine the physiological factors that can increase susceptibility to the negative effects of heat in persons with schizophrenia and profile the social and community-level factors aggravating or mitigating these risks. An interdisciplinary, multi-level approach is essential to facilitate effective heat-health planning and community adaptation to prevent heat-related injuries and deaths in persons with schizophrenia during extreme heat.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"995 ","pages":"Article 179965"},"PeriodicalIF":8.2,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Deeper insights can be obtained by interpreting statistical models trained on data subsets that correspond to specific emission–dispersion conditions. To achieve such distinct subsets, we present a robust and reproducible methodology for partitioning the multidimensional state space, defined by pollution sources and meteorological variables, into a large number of clusters at each monitoring location.

These pollutants were observed at 85 air quality monitoring stations across Israel. The resulting clusters capture sub-daily temporal patterns that are indicative of distinct emission–dispersion scenarios in the region.

We observed a positive relationship between annual precipitation and productivity across precipitation gradients; however, this nonlinear pattern differed from native ecosystems and varied by agroecosystem type. Rangeland ANPP was strongly coupled to annual precipitation, increasing nearly 20% for every 100 mm of precipitation. Croplands and pasturelands showed significantly decreased sensitivity, although grouping crops by photosynthetic pathway and crop type revealed some significant patterns. Underlying these patterns in sensitivity were large differences in overall ANPP among agroecosystems; cropland ANPP was up to 6.7-fold greater than rangelands and 2.6-fold greater than pasturelands, despite overlapping precipitation gradients.
