Assessment of lead contamination in peatlands using field portable XRF

摘要: Ombrotrophic peatlands are highly sensitive to atmospheric heavy metal deposition. Previous attempts quantify peatland lead pollution have been undertaken using the inventory approach. However, there can be significant within-site spatial heterogeneity in concentrations, highlighting need for multiple samples properly storage. Field portable x-ray fluorescence (FPXRF) continues gain acceptance study of contaminated soil, but has not thus far used assess contamination. This compares concentrations surface peat from South Pennines (UK) derived (a) FPXRF field, (b) lab on dried and (c) ICP-OES analysis. field data directly comparable when measurements corrected water content, both easily estimate acid extractable regression equations. is a successful demonstration as tool time- cost-effective means determining content peatlands, which will allow rapid landscape scale reconnaissance, core logging, surveys sediment tracing.
