Mobile monitoring strategies are increasingly used to provide fine spatial estimates of multiple air pollutant concentrations. This study demonstrates a novel approach using positive matrix factorization (PMF) applied multipollutant mobile data assess source-specific pollution exposures and estimate associated emission factors. Data were collected from one-year monitoring, with an average 26 repeated measures size-resolved particle number counts (PNC), PM2.5, BC, NO2, CO2 at 309 sites in Seattle 2019 2020. PMF was characterize underlying source-related The sources these six factors included emissions aviation, diesel trucks, gasoline/hybrid vehicles, oil combustion, wood accumulation mode aerosols. Fuel-based for three transportation-related also estimated. reveals that PNC ultrafine particles size <18, 18–42, 42–178 nm dominated by features aircraft, both combustion. Gasoline hybrid vehicles contributed the most NO2 can be extended other metropolitan areas, enhancing exposure assessment epidemiology studies.

Unlocking the Potential of Tracer Technology as a Tool for Quantifying Fertilizer Use Efficiency

Journal of Plant Nutrition and Soil Science, Год журнала: 2025, Номер unknown

Опубликована: Фев. 25, 2025

ABSTRACT With the increase in global population, importance of efficient use fertilizer will become essential, and development innovative effective efficiency (FUE) strategies is a need hour. However, injudicious leads to nutrient losses environmental pollution. Several technologies have been developed improve crop production uptake from applied fertilizers, including balanced fertilization, foliar application, mixed controlled‐release slow‐release nano‐fertilizers. To quantify several indicators are being used such as efficiency, agronomic partial factor productivity. Isotope tracer studies proven useful measuring soil availability, quantifying by plants through nutrients derived fertilizer, monitoring environment, establishing transport accumulation inside plants. Results stable isotopes 15 N, 13 C, 34 S radioisotopes 32 P 65 Zn accurately measure potential crops their partitioning efficiency. Radioisotope demonstrated that application can be faster more than for some crops, offering promising approach improving FUE. Despite its potentiality, research has many challenges, ensuring target concentrations within analytical method ranges, accounting isotopic interference non‐target compounds, limited access specialized equipment measurement errors. overcome these constraints, advanced study methodology integration with sensor‐based detection must augment site‐specific management precision agriculture. Continued collaborations valuable exploiting full technology different optimizing dose boost yields sustainably, thereby contributing food security sustainability.

Application of Antimony Stable Isotopes in Revealing the Source and Vertical Migration of Sb in Soil

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Март 18, 2025

Antimony (Sb) is a widespread contaminant that poses potential carcinogenic risks worldwide. Many countries are grappling with significant historical Sb-containing waste, leading to soil contamination, which of international concern. The lack clarity on Sb sources and migration mechanisms in limits the effective prevention control pollution. This study utilized stable isotope techniques analyze profiles from two pollution scenarios, aims quantifying sources, understanding processes, elucidating isotopic fractionation soil. results reveal surface originates primarily atmospheric dry deposition (31.7-56.3%), wet (19.6-32.7%), rock weathering (<21.0%). In subsurface soils, mainly comes solutions resulting desorption upper layers, adsorption by iron minerals, manganese (hydr-)oxides, organic matter impeding its downward movement. Deeper layers contain derived parent weathering, impacted secondary mineral adsorption. Groundwater aids influences during water-soil exchange. research introduces novel framework for quantitatively tracking enhances scientific geochemical behavior
