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.

The metal contents of 19 tea leave samples, Camellia sinensis L., from Yen Bai and Tuyen Quang provinces were determined using inductively coupled plasma optical emission spectrometry (ICP-OES) and atomic absorption spectrometry (AAS). Total 18 elements in tea leaves were determined including macroelement such as Al, Ca, K, Mg, Mn; trace element such as Na, Ba, Fe, Cu, Sn, Zn, Se, Ni, B and heavy metal (Pb, Hg, Cd and metalloid As). The results show that, K content was the highest among the macroelement, followed by Mg, Ca, Mn and Al. There was a wide variation of the trace metal content among the tea leaves coming from different province. The levels of heavy metal content in most of the samples were not detectable or below the acceptable level as required by Ministry of Health.
