One of the effects of industrialization
of communities is great consumption of different chemical substances
that resulted severe consequences such as, chronic poisoning that most
of them will be dangerous and life threatening. The metals are part
of major substances with mutational and carcinogenic effects. With respect
to the collective characteristics of these metals on human and environmental
health, we decided to evaluate their adverse effects. Present study
was done in Gillan province (North of Iran) on green leaf of Tea cultivated
in Lahijan and Fuman cities. The samples were selected from ten regions
and five samples from selected areas were studied. evaluation of metals
in green leaves (Pb, Cd, Cr and Zn) was carried out by atomic absorption
spectrometry .The results showed a significant relation between the
amount of lead and regions (P < 0.05) and also comparison between these
mean numbers showed that in Eastern station, lead had the highest amount
with average of 5.300 ppm in Fuman and 4.300 ppm in Lahijan samples.
Amounts of other metals (Cd, Cr and Cu) were below standard that proposed
by WHO. With respect to obtained results, there is a great potential
for hazardous substance in the studied regions and it is necessary to
make a serious analysis about this substances in other regions of Gillan
Province.
