Exercise 05 – Wessenden Moor, Fe, Pb, Br and Ca levels
Peat extracted from Wessenden Moor in West Yorkshire in November 2002. Samples of 2cm diameter were analysed taken from a 50cm deep core. Different depths of the peat core were analysed using X-Ray Fluorescence (XRF) analysis to measure the concentration of Iron, Lead, Bromine and Calcium. The results obtained after performing XRF analysis are shown in table 1
