Application of laser ablation inductively coupled mass spectrometry (LA-ICP-MS) for the determination of major, minor, and trace elements in bark samples

摘要: The large surface area of barks from many tree species enables the effective accumulation pollutants. Therefore, analysis bark material will provide useful information about degree pollution a certain region. determination main, minor, and trace elements (Al, Ca, Cd, Ce, Cr, Cu, Fe, Mn, P, Pb, S, Ti Zn) in was performed with an Nd:YAG laser coupled to ICP-MS system. Bark standards for calibration by ablation were prepared different layers which differ some relevant concentrations. Four digestion procedures decomposition standard pellets, numbers shots per sample samples region necessary have been investigated. Representative results obtained 5 or more taken individuals one sampling averaged element concentrations 10 separately placed each sample. Laser applied characterization real regions high low burden. It shown that method is well suited characterize degrees environmental impact. Anthropogenic sources responsible higher most under investigation.
