The present study aimed to determine concentration of heavy and trace metals (Fe, Cu, Mn, Zn, Co, Cd, Pb, As, and Hg) in honey by inductively coupled plasma optical emission spectrometry (ICP-OES). Samples passed through wet digestion methods following the optimum digestion condition by applying the reagents (30mL HNO3:30mL H2O2) at temperature of 270°C for 3 hours. The average concentrations of the metals are found in the range of 5.32-28.6 mg/kg for Fe, 0.24-0.749mg/kg for Cu, 0.627-4.401mg/kg Zn, 0.41-3.15mg/kg for Mn, 0.08-0.112 mg/kg for Co, 0.25-0.325mg/kg for Pb, 0.24-0.46mg/kg for As, ND-0.031mg/kg for Hg and 0.02-0.03mg/kg for Cd. This study shows that the honey in the studied area is a good sources of essential metals (Fe, Cu, Mn, Co and Zn) as they are found to be in the permissible limit. Moreover, the maximum concentration of the toxic metals determined in this work are below the level of toxicity as per the standard set by WHO/FAO.

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.
