There have been some reports that adding sulfur (S) to plants reduces Cd accumulation in shoots by increasing its retention in roots due to complexation of Cd by S-containing ligands. Consequently, low S availability in some agricultural soils could favor Cd contamination of durum wheat grains. We conducted a greenhouse experiment to test whether S deficiency would reduce Cd retention in roots, thus favoring its allocation to shoots. Durum wheat was grown in a nutrient solution containing a low level of Cd (100 nM) with sufficient (+ S) or deficient (-S) sulfate levels and harvested at heading. Surprisingly, in the -S treatment, more Cd was retained in roots and less allocated to shoots than in the + S treatment, and the same applied to P, K, Ca, Mg, Cu, Mn, Mo, and Zn. The reduced aboveground biomass resulting from S deficiency explained both the reduced net uptake (i.e., the total quantities of elements in the plant) and the reduced allocation of elements to shoots. Depending on the relative effects of S deficiency on shoot biomass compared to the effects of a reduction in S uptake and allocation to shoots, the reduced supply of S increased the concentrations of Cd and of P, K, Mn, Mo, and Zn in the shoot, whereas the concentration of Cu decreased, and that of Ca and Mg remained unchanged. The higher concentration of Cd in the shoots of S-deficient plants suggests that attention should be paid to the consequences of insufficient S for Cd contamination of durum wheat.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144109353","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}

To reduce existing environmental burdens of litter, clean-up events have increased in popularity. Here, we report on the results of the Clean Shores, Great Lakes project, in which we conducted 69 volunteer-based clean-ups along the Tanzanian shorelines of the African Great Lakes (Victoria, Tanganyika, and Nyasa (also known as Lake Malawi)). A total of 5483 volunteers engaged with the project across all clean-up sites, collecting 431,328 pieces (25,981 kg) of anthropogenic litter. Expressing the data as normalized to area (items m^-2) or effort (items individual^-1 h^-1) revealed that the interpretation of a polluted site varies with units, highlighting the need for consistency in the field. Litter density varied from 0.06 to 13.89 items m^-2 and 5.2-706 items individual^-1 h^-1. Plastics were the major litter type constituting 75% of all litter (mean = 74.2 ± 12.5% across all sites), while clothing (10.9 ± 9.5%) and fishing gear (3.7 ± 5.2%) were also prevalent. Two items constituted > 40% of all collected litter, namely plastic beverage bottles (average 23.7 ± 17.1%, range 0-72.9%) and plastic bags (average 19.7 ± 13.2%, range 1-50.3%). Prioritizing intervention measures on these two items could reduce litter leakage significantly.

This study analyzed data from 17 hydrometric stations (1981-2017) across two periods to assess drought impacts on flow behavior in the Bandar Abbas watershed, Iran. Using the Stream Drought Index, noise variance, Lyapunov exponent (LE), Hurst coefficient (H), approximate entropy (ApEn), and the Mann-Kendall trend test, we identified significant changes. Drought severity increased, with noise variance in drought patterns rising by up to 3475% in central zones and dropping by 70% elsewhere, signaling more frequent and intense dry spells. River flow declined at 12 stations, with the Mann-Kendall test confirming negative trends, reducing water availability by up to 150% in volume at northern sites. LE decreased by 1165% across most stations, indicating drought lowered flow sensitivity to initial conditions, while H fell by 50%, weakening long-term flow memory. Meanwhile, ApEn surged by 354%, reflecting increased randomness and reduced predictability, particularly in northern areas. These shifts strain water availability for ecosystems and agriculture, disrupt aquatic habitats, and challenge management strategies reliant on stable flow. This multi-tool approach, novel in this context, merges chaos, memory, and randomness analyses to clarify drought's effects. Focused on Bandar Abbas, the findings offer insights for arid regions globally, providing a framework for adaptive water management to address scarcity and unpredictability in river systems under climate stress.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144109350","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}

This material was characterized by several physicochemical methods, then applied to the elimination of tetracycline (TC) and norfloxacin (NC). The results obtained showed that the modification method used, although significantly altering the mesoporous structure of the original biochar, generates several functional groups on the surface of the material, giving it excellent adsorption properties. These properties were evaluated by studying the influence of various experimental parameters such as the pH of the solution, the mass of doped biochar, and the contact time on the amount of antibiotic adsorbed. Adsorption studies revealed maximum amounts of TC and NC adsorbed of 65 and 96 mg/g at pH = 8 and 6 respectively with 50 mg of adsorbent for an equilibrium time of 90 min for TC and 60 min for NC at a concentration of 15 mg/L for both antibiotics. This adsorption capacity led to the removal percentages of up to 90 and 82% for TC and NC, respectively. After five cycles of use, a decrease in adsorption efficiency of 9% for TC and 11% for NC was observed, demonstrating the impressive stability of the synthesized material.

This review study synthesizes findings from multiple studies to provide a comprehensive overview of eDNA collection strategies in diverse settings. The review examines the techniques used for sampling eDNA in water, air, soil, sediment, and coral reef ecosystems. Water filtration, sediment sampling, and passive sampling devices are commonly used methods for collecting eDNA in aquatic environments. These techniques provide non-invasive ways to identify and track aquatic organisms, offering vital information about the interactions within the community and the global distribution of species. Similarly, the use of airborne eDNA sampling techniques is becoming increasingly promising for evaluating biodiversity on land, although there is room for improvement. Soil eDNA extraction techniques involve the use of soil coring to collect samples, followed by DNA extraction from these samples, and the application of metabarcoding methods. These techniques allow for thorough investigations of biodiversity in the soil. Specialized techniques for collecting eDNA are required for coral reef ecosystems due to their intricate habitat structure and fluctuating water conditions. The importance of choosing appropriate techniques for eDNA collection based on ecosystem parameters and research objectives is emphasized by comparative analysis.

However, EGR generally shows adversely effective in particulate matter (PM) emissions. The chemical composition of the PM with the application of EGR is not well identified because few previous publications focus on this topic, especially for high EGR rate cases. In this paper, emission characteristics of organic carbon (OC, OC₁-OC₄), elemental carbon (EC, EC₁-EC₂), and particulate semi-volatile organic compounds (SVOCs) including 18 n-alkanes and 20 polycyclic aromatic hydrocarbons (PAHs) for a common-rail diesel engine at mild and high EGR rate conditions (up to maximum achievable level while maintaining stable combustion) were analyzed at four steady-state conditions comprehensively. It can be clearly observed that EGR rate instead of load and speed significantly affects the EC emission under the experimental conditions. EC emission increase with increasing EGR rate, which is divided to two sections, i.e., slight increase from 0 to 30% (mild EGR rate) and sharp increase from 30 to 45% (high EGR rate). TC is dominated by OC₁, OC₂, and EC₁ at low EGR rate, and the fraction of EC₁ evidently increases with increasing EGR rate. It is observed that TC is heavily dominated by EC₂ at highest EGR rate ranges, which corresponds to the lower heat release rates (lower HRR_max at higher EGR rate) and lower air-fuel ratio at these conditions. All the target PAHs increase with increasing EGR rate at the four operation modes. The adverse effect of EGR on PAH emission is less significant than EC emission. Moreover, the effect of EGR rate on the PAH ring distribution is not significant. Both of total ∑C₁₆-C₂₅ and ∑C₂₆-C₃₃ emission rates evidently increase at high EGR rate condition in comparison with those at baseline and mild EGR condition cases, which indicates that both fuel-derived and oil-derived n-alkanes exhibit higher emission rate at high EGR conditions compared with those at baseline and mild EGR condition. The application of EGR helped with other controlling strategies (e.g., fuel injection, after-treatment device) is suggested to suppress the carbonaceous PM formation for the modern common-rail diesel engine.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144092410","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}

In the arid environment of the 70-82° E belt, coarse-mode mineral particles dominated, and LFR was low and inversely correlated with AOD. However, a fivefold increase in LFR in the 82-85° E belt was associated with the formation of deep convective clouds during the lockdown. In the 85-90° E belt, LFR declined during the lockdown but increased in 2017-2019, supporting the roles of mixed-phase processes in the dry and moist environments.
