| Waste water from paint manufacture was absorbed onto filter paper, dried at 105C and then analysed. Calibration samples consisting of high purity metal powders were mixed in a ball mill with KBr and pressed into pellets. Detection limits were, in general, found to be sufficient for measurements against maximum safe exposure limits (mg/kg) | |||||
