Pb uptake, accumulation, and translocation in plants: Plant physiological, biochemical, and molecular response: A review

Heliyon, Год журнала: 2024, Номер 10(6), С. e27724 - e27724

Опубликована: Март 1, 2024

Lead (Pb) is a highly toxic contaminant that ubiquitously present in the ecosystem and poses severe environmental issues, including hazards to soil-plant systems. This review focuses on uptake, accumulation, translocation of Pb metallic ions their toxicological effects plant morpho-physiological biochemical attributes. We highlight uptake metal controlled by cation exchange capacity, pH, size soil particles, root nature, other physio-chemical limitations. toxicity obstructs seed germination, root/shoot length, growth, final crop-yield. disrupts nutrient through roots, alters plasma membrane permeability, disturbs chloroplast ultrastructure triggers changes respiration as well transpiration activities, creates reactive oxygen species (ROS), activates some enzymatic non-enzymatic antioxidants. also impairs photosynthesis, water balance mineral nutrients, hormonal status, structure permeability. provides consolidated information concentrating current studies associated with Pb-induced oxidative stress conditions various plants, highlighting roles different antioxidants plants mitigating Pb-stress. Additionally, we discussed detoxification tolerance responses regulating gene expressions, protein, glutathione metabolisms resist phytotoxicity. Overall, approaches tackle have been addressed; phytoremediation techniques biochar amendments are economical eco-friendly remedies for improving Pb-contaminated soils.

Simulation of river flow in Britain under climate change: Baseline performance and future seasonal changes

Hydrological Processes, Год журнала: 2021, Номер 35(4)

Опубликована: Март 23, 2021

Abstract Climate change is likely to manifest in river flow changes across the globe, which could have wide‐ranging consequences for society and natural environment. A number of previous studies used UK Projections 2009 (UKCP09) investigate potential impacts on flows Britain, but these projections were recently updated by release UKCP18, thus there a need update studies. Here, UKCP18 Regional (12 km) are applied using national‐scale grid‐based hydrological model, future seasonal mean Great Britain. Analysis model performance baseline climate data (1980–2010) shows relatively good agreement with use observation‐based data, particularly after application monthly precipitation bias‐correction. two time‐slices (2020–2050 2050–2080) suggests large decreases summer country (median −45% 2050–2080), possible increases winter 9% especially north west. Information range latest necessary develop appropriate adaptation strategies, comparisons can help existing plans, although such often not straightforward.

Geo-Accumulation Index of Manganese in Soils Due to Flooding in Boac and Mogpog Rivers, Marinduque, Philippines with Mining Disaster Exposure

Applied Sciences, Год журнала: 2022, Номер 12(7), С. 3527 - 3527

Опубликована: Март 30, 2022

This paper presents the effects of flooding on accumulation manganese (Mn) in soils within proximity Boac and Mogpog rivers Marinduque The Philippines. Marinduque, an island province Philippines, experienced two catastrophic tailings storage facility (TSF) failures 1990s that released sulfide-rich into major rivers. Philippines experiences 21–23 typhoons every year, 11 which pass thru causing inundation floodplain areas province. A flood hazard map developed using LiDAR DEM was utilized for accurate representation events. portable X-ray fluorescence spectrometer (pXRF) a Hannah multi-parameter device were used on-site analyses Mn concentration water physico-chemical properties, respectively. Spatial grid mapping with zonal statistics employed comprehensive analysis all data collected processed. Correlation carried out concentrations soil surface water, electrical conductivity (EC), total dissolved solids (TDS), pH, temperature, curve number (CN), heights. indicates runoff response characteristic Mogpog-Boac River basin. results show 40% area subjected to high hazards heights above 1.5 m. content had statistically significant moderate positive correlation height (r = 0.458) negative pH −0.438). condition suggested more extensive promotes contamination rivers, source includes mobilization Mn-bearing silt, sediments, mine drainage from abandoned pits TSFs. There is also strong between relationship attributed solubilization precipitates based geochemical modeling results. Using Muller’s geo-accumulation index, 77.5% identified as “moderately contaminated” average 3.4% by weight (34,000 mg/kg). described this study could guide relevant regional, national, local government agencies planning appropriate intervention, mitigation, remediation, rehabilitation strategies limit human exposure highly contaminated areas.

Projections of Global Land Runoff Changes and Their Uncertainty Characteristics During the 21st Century

Earth s Future, Год журнала: 2023, Номер 11(4)

Опубликована: Апрель 1, 2023

Abstract Quantifying uncertainty in runoff changes has profound implications for future investigations and will support global climate model improvement. We analyze the from outputs of 5th 6th Coupled Model Intercomparison Projects (CMIP5 CMIP6) decompose projected into three main sources: internal variability, uncertainty, scenario uncertainty. The results indicate that 73% 72% land area, respectively, shows an increase CMIP5 CMIP6 under high‐emissions scenarios long term (2070–2099) relative to 1970–1999, across all increases by 10.8% RCP8.5 16.1% SSP5–8.5 during 2070–2099 1970–1999. Regions with increasing are mainly Southeast Asia, eastern Africa, Qinghai‐Tibet Plateau high latitudes Northern Hemisphere. agreement is greater than low‐emissions scenarios. For (RRC) CMIP6, contribution variability gradually decreases over time (from 49.2% 2.0%) while 0.6% 30.0%); this result similar CMIP5. Spatially, RRC been a major source accounting more 60% total most regions. study help us better understand also provide theoretical basis developing mitigation measures changes.
