According to recent research from Kingston, Canada, "The mineral form, grain size and texture of As-bearing particles are important factors influencing the risk to human health associated with exposure to As-contaminated soils, sediments and mine wastes. Mining of arsenopyrite-bearing gold ores in Nova Scotia in the late 1800s and early 1900s has left a legacy of weathered, As-rich tailings deposits in more than 60 gold districts across the province."
"Fourteen samples of near-surface tailings and one of soil from several former gold mines frequented by the public were sieved to
<150 mu m and characterized using conventional mineralogical techniques (XRD, microscopy and EPMA) and synchrotron micro-analysis (mu-X-ray diffraction, mu-X-ray fluorescence and mu-X-ray absorption spectroscopy). Two high-As (> 20% As) mill concentrates exposed at the surface within the tailings deposits are ...
