It is known
that, exposure to lead cause to various detrimental effects on the
hematopoietic, kidney, reproductive, and central nervous system. One of the
sources of lead intake, is colored decorations applied over glazes of some
ceramic, porcelain and glass tableware. Also, the cadmium and chromium can be
found in these objects.

In this study,
aimed to determine the amount of lead, cadmium and chromium found in colorful decorated
ceramic, porcelain and glass kitchenware which in daily use at home in Ankara.
For this purpose, 84 analyses were performed for 31 samples (18 porcelain, 9
glass, 4 ceramic). 16 of the samples were made in China, 8 inTurkey, 3 in
Germany, one each in France, England, Cyprus and Malaysia. Before, the
decorated/painted surface and the unpainted glazes of the samples were analyzed
and finally the samples that homogenized by grinding, were analyzed by XRF.

As well as lead,
the chromium and cadmium were found in the decorated surface analysis of some
samples. The average amounts of lead (by weight), chromium and cadmium, were
determined as 1.82% (in 26 samples ), 0.154% (in 20 samples) and  0.189% (in 6 samples), respectively,  in the decorated surface analysis. The lead
was determined in the unpainted glazed surface of 3 of 31 samples, only.  The chromium and cadmium were not found in
the unpainted glazed surfaces of all samples. The average amounts of lead and chromium
0,117% (in 26 samples), 0.021% (in 8 samples) were found in the grinded
samples, respectively. The cadmium could not be determined in none of all
grinded samples.

The lead, chromium and cadmium were not found in any
analyzed parts of 3 Turkish products (1 glass, 1 porcelain, 1 ceramics). A high
amount of lead (decor=9.66%, 9.56%=glaze, grinded sample=1.15%) was observed in
all analyzed parts of the British ceramic samples. The lead, chromium and
cadmium, were determined as 7.18%, 0.118% and 0.409% (the highest amount of
cadmium in the study), respectively, in decorated surface of a china glass. The
results of this study indicated that the daily use of colorful decorated
tableware is a high human health risk factor in the current time, still.
