Abstract A two-part single-laboratory validation study was conducted for determination of the P and K content in commercial fertilizer materials by inductively coupled plasma-optical emission spectrometry (ICP- OES). While several methods exist for determination of P and K in fertilizer products, the main focus of this study was on ICP-OES determination, which offers several unique advantages. Fertilizer samples with consensus P and K values from the Magruder and Association of Fertilizer and Phosphate Chemists (AFPC) check sample programs were selected for this study. Validation materials ranging from 4.4 to 52.4% P2O5 (1.7 to 22.7% P) and 3 to 62% K2O (2.5 to 51.5% K) were utilized. Because all P and K compounds contained in fertilizer materials are not "available" for plants to use, this study was conducted in two parts. Part A focused on ammonium citrate–disodium EDTA as the extraction solvent, as it estimates the pool of fertilizer P and K that is considered available to plants. Part B focused on hydrochloric acid as the digestion solvent, as it estimates the total P and K content of the fertilizer product. Selectivity studies indicated that this method can have a high bias for fertilizer products containing sources of phosphite or organic P compared to gravimetric or colorimetric methods that measure just orthophosphate. Provided the analytical challenges outlined in this study are addressed, this method offers the potential for a quick, accurate, and safe alternative for determining the P and K content of commercial inorganic fertilizer materials.

Abstract The availability of Cd, Co, Cr, Cu, Mn, Ni, Pb, Fe and Zn of dust from vehicle air and pollen filters were investigated by four-step BCR (European Community Bureau of Reference) sequential extraction procedure. The acid-soluble, reducible, oxidizable, residual extracts were measured by inductively coupled plasma-optical emission spectrometry (ICP-OES). The results indicated that both of air and pollen filter dusts contained higher concentration of Fe. To estimate the accuracy of the method the standard reference material BCR 701 was used. The results for recovery all the elements were found in the range 95.4-101.3%. The mean concentrations [μg/g] of trace elements in dusts from air filters/pollen filters were: cadmium 16.72/17.56; cobalt 24.22/23.72; chromium 46.02/55.44; copper 44.92/37.67; iron 1868.03/1854.92; manganese 231.2/213.64; nickel 38.89/45.27; lead 60.99/67.17; zinc 199.58/201.25. The results obtained are in agreement with data reported in the literature.
