However, a lack of efficient means and incomplete monitoring data are the main obstacles impeding soil pollution management and prevention in China. Moreover, it is rare to examine the possibility and reliability of using field-collected earthworms to assess the pollution degree of soil heavy metals in real-world situations at a large field scale. In this study, we investigate the potential use of field-collected earthworms as bio-indicators to assess the pollution characteristics and risks of heavy metals (Zn, Pb, Cu, As, Cd, and Cr) across three typical regions (Xiaokeng Reservoir, Dabaoshan Mine, and Smelter/Steel Plants) in Shaoguan, one of six trial zones identified for the Soil Pollution Prevention and Control Action Plan in China. Our results unveil the existence of significant differences in the spatial distribution and bioavailability of heavy metals in soils and earthworms across these regions. The average contents of Zn, Pb, Cu, As, Cr, and Cd in soils were 329.7 ± 476.5, 180.9 ± 262.4, 82.9 ± 197.8, 66.6 ± 61.6, 53.3 ± 53.6, and 7.2 ± 8.2 mg/kg, while those in earthworms were 113.6 ± 112.1, 99.4 ± 106.8, 90.0 ± 126.9, 24.7 ± 30.8, 8.8 ± 9.4, and 5.1 ± 3.4 mg/kg, respectively. The internal exposure dose of heavy metals in earthworms is found to more accurately reflect their bioavailability under true environmental conditions than the external exposure dose in soils. The bioaccumulation factor (BAF) exhibited the highest values for Cd (0.01–24.40), followed by those for Pb (0.06–9.94), Cu (0.12–5.23), Cr (0.02–1.90), As (0.02–1.18), and Zn (0.06–1.17). Further principal component analysis (PCA) and random forest (RF) classification ascertain that earthworms are more capable of differentiating heavy metal pollution in different regions than soil alone. Compared to the routine analysis of the total heavy metal content in soils, our novel strategy demonstrates the superiority of employing field-collected earthworms as bio-indicators for monitoring heavy metal pollution and discriminating potential sources of soil pollution in a real scenario.</p>","PeriodicalId":29795,"journal":{"name":"Environment & Health","volume":"3 6","pages":"616–625 616–625"},"PeriodicalIF":0.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/envhealth.4c00249","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144320472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent evidence suggests that ambient temperature may influence suicide risk. This study examines the association between temperature and suicide in Thailand’s tropical climate, focusing on Chiang Mai and Bangkok provinces, and quantifies the attributable burden. Daily suicide and meteorological data from 2002 to 2021 were analyzed using a time-stratified case-crossover approach with a distributed lag nonlinear model, adjusted for relative humidity. Province-specific estimates were pooled through a multivariate meta-regression model. The study found a positive, mostly linear association between temperature and suicide risk, with a relative risk (RR) of 1.70 (95% CI: 1.35, 2.15) across the temperature range. Approximately 24.61% of suicides were attributable to temperature, with 12.05% due to hot temperatures above the 66th percentile. The pooled attributable fractions were higher in the 0–64 age group compared to those aged ≥65, while differences between sexes were not statistically significant. This study highlights the significant association between higher ambient temperatures and increased suicide risks in Thailand, emphasizing the need to integrate climate considerations into mental health and suicide prevention policies.
