Calcium carbonate (CaCO₃) is widespread and has the potential of regulating As fate directly or indirectly. However, the influence of CaCO₃ on ferrihydrite transformation and the associated As mobilization/redistribution in SRB-containing environments remains unclear. Therefore, in this research, batch experiments coupled with a series geochemical, spectroscopic, and microscopic technologies were conducted collectively to address the research gap above. The results suggested that under low CaCO₃ loading conditions, the reductive transformation of ferrihydrite to Fe−S minerals resulted in a significant release of adsorbed As into the solution and As(V) reduction to more mobile and toxic As(III). Inside the cell of SRB, there existed S and As zone (no Fe), where As(V) might be reduced by S^2- without interference of Fe(III). Although the high CaCO₃ loadings exerted little effect on Fe(III) reduction, they promoted ferrihydrite transformation into dufrenite and vivianite, which sequestered As effectively via structural incorporation process, retarding As mobilization. Besides, the coprecipitation of As with dufrenite and vivianite enhanced the stability of solid phase As. Overall, the high CaCO₃ loadings altered the mineralogical transformation of ferrihydrite and the associated As biogeochemistry significantly in SRB-containing environments. Regulating ferrihydrite transformation and the associated As fate via CaCO₃ addition is an effective approach for mitigation of As mobilization in the aquifer near mining area.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"12 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142884364","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}

The transport, retention, and release of HMs in porous media are highly related to their environmental fate and risk to groundwater. Column transport experiments and numerical simulations were conducted to investigate the retention and release behaviors of Cu²⁺, Pb²⁺, Cd²⁺, and Zn²⁺ in the presence and absence of kaolin under varying ionic strengths and cation types. The interaction between HMs and soil colloids is critical to these processes, yet it remains poorly understood. In both single and multi-metal systems, the mobility of HMs ranked as Cd²⁺ > Zn²⁺ > Cu²⁺ > Pb²⁺, is influenced by their hydrolysis ability. Multi-metal systems showed higher mobility due to competition for retention sites, and Ca²⁺ enhanced transport more than Na⁺ due to greater affinity to the sand surface. Kaolin reduced HM transport by adsorption and led to irreversible retention. Cation exchange (Na⁺ replacing Ca²⁺) followed by reduced ionic strength promoted HM release due to the remobilization of kaolin associated with HMs. Uniform, nonmonotonic, and exponential retention profiles indicated variations in the spatial distribution of HMs. The Pb²⁺ and Cu²⁺ were more retained near the column inlet than Cd²⁺ and Zn²⁺, indicating limited mobility in the deep subsurface. Numerical simulations well described HM transport, considering the adsorption and desorption of HMs and the solid-water interface.

However, the emerging threat of climate change poses a significant challenge to these agricultural-dependent economies. Sub-Saharan African countries are at risk of experiencing the severe effects of climate change on their agricultural productivity. This paper examines the impact of climate change, as proxied by CO2 emissions, on the agricultural production index in Sub-Saharan Africa. The agricultural production index consists of the Crop and Livestock Production Index. Data for the study were extracted from the World Development Indicator, covering the period 1996-2021. The analysis utilized the Panel GMM estimation technique. The study revealed that the effects of climate change vary on crop production and livestock production indices. While climate change has a positive and significant effect on the crop production index, it exhibits a negative and significant impact on the livestock production index. Factors such as technological development, arable land size, and renewable energy use play a significant role in enhancing agricultural productivity in Sub-Saharan Africa. Conversely, government effectiveness and labor force exhibit a negative influence on the crop production index. In contrast to the crop production index, climate change has a detrimental effect on livestock productivity. Additionally, technological progress, renewable energy use, and arable land size have a negative impact on livestock productivity. The study recommends that African governments implement policies to promote technological progress, improve institutional quality, and increase renewable energy use in the agricultural sector to achieve sustainable agricultural growth. Policymakers and governments are also encouraged to address the challenges of communal land ownership and unclear property rights.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Irrigation can either alleviate or exacerbate heat stress, quantification of which is crucial in intensely irrigated agricultural lands such as the Imperial Valley in southern California. We investigate the impact of irrigation on wet bulb globe temperature (WBGT), a key indicator of heat exposure in humans, using a validated high-resolution Weather Research and Forecasting (WRF) regional climate model, during day and night and in different seasons. We find that irrigation reduces WBGT by 0.3–1.3  °C during the daytime in summer due to strong evaporative cooling. However, during the summer nights, irrigation increases WBGT by 0.4–1.3 °C, when a large increase in humidity sufficiently raises the wet-bulb temperature. Urban and fallow areas adjacent to cropped fields also experience increased heat stress due to moisture advection from irrigated areas. Our results can inform heat-related policies in agricultural regions of California and elsewhere.

A field survey of Cd-contaminated rice-wheat rotation farmlands in China provided detailed comparison of Cd accumulation capacity by rice and wheat grains. The results indicated that Cd-BCF of wheat grains (median values 0.42) were obviously higher than those of rice grains (median values 0.12) under wide soil Cd levels and pH ranges. Soil Cd levels rather than pH played a vital role on Cd accumulation by wheat grains, and high wheat grain Cd concentrations (0.12-0.13 mg kg⁻¹) were even observed in mildly alkaline soil that normally have low Cd mobility. Dietary Cd exposure risks were assessed by the crop Cd exposure models considering different soil Cd content, pH and dietary structures of residents. The results indicated that the intake of wheat grains contributed 56.1-86.5% of total crop Cd exposure, with an increase in its contribution with the increase of soil pH. Residents favoring wheat would have a significant Cd exposure risk if consuming crops from soils with Cd levels above 0.41 mg kg⁻¹, which was considerably lower than the current soil Cd risk screening value for alkaline soils (0.6 mg kg^-1). Our findings indicate a high Cd accumulation capacity of wheat grains and consequent risk of dietary Cd exposure, which deserves further exploration on the correlation among soil Cd screening value, grain Cd limit value and its dietary exposure risk.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"31 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142884429","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}

The insights gleaned from this study are manifold: (1) There exists a hierarchical order in the regional sustainable carrying capacities, ranking from highest to lowest, as follows: economic, ecological, resource-environmental, and social. (2) Regions boasting a high regional sustainable carrying capacity typically exhibit robust synergy and coordination among economic, social, resource, environmental, and ecological dimensions of sustainability. (3) Regions with a strong economic sustainable carrying capacity have a more pronounced likelihood of evolving into areas with an overall heightened sustainable carrying capacity amid ongoing development.

The research objectives of this paper are: ① to propose a theoretical framework and methodological system for evaluating sustainable carrying capacity, providing technical guidance for sustainable carrying capacity assessments in other river basin economic zones; ② to analyze the evolution characteristics and influencing mechanisms of the sustainable carrying capacity in the Yangtze River Economic Belt, offering a case reference for policy formulation on sustainable development in other river basin economic zones.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"32 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142884592","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}

Consequently, several studies have been conducted on this topic. However, the results of the current research vary, and a comprehensive review is lacking. This study summarized the volatile organic compounds (VOCs) emission and risk assessments in the petrochemical industry based on data collected from previous studies. A discussion of VOC emission characteristics is provided. The effects of VOCs on human health, ozone formation potential (OFP), and secondary organic aerosol (SOA) are also reviewed. According to this review, the VOC emission characteristics are related to the raw materials and processes. Moreover, research methods can lead to certain biases. In entire petrochemical plants, alkanes were the largest contributors to VOC emissions, with <em>n</em>-pentane, <em>n</em>-butane, and propane frequently appearing in the top five emission lists. Among the process unit areas, alkanes were the major contributors, except for the delayed coking unit, where aromatics significantly contributed. Regarding the risks associated with VOC emissions, benzene, and 1,3-butadiene are common carcinogens impacting human health. 1,3-Butadiene, benzene, and acrolein are major contributors to noncarcinogenic risk. OFP is related to VOC emissions and their corresponding reactivities. Alkenes, alkanes, and aromatics are major contributors to OFP. Aromatics were the largest contributors to SOA concentration. In the future, research methods on the characteristics and risks of VOC emissions need to be further improved. More precise sampling techniques and advanced analytical instruments should be employed to better characterize VOC emissions. Overall, this study considered the characteristics of VOC emissions from petrochemical industrial areas, as well as the risks to the environment and health to provide a reference for the control of VOCs.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"202 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142879582","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}
