ABSTRACT
This paper is carried out to determine the venous blood gas components and heavy metals, such as lead, cadmium and copper, in blood between urban and rural teenager. The subjects were 34 in urban, Taegu city and 37 in rural, Euisung-Gun. But smokers were excluded. The specimens were sampled in May, 1985. The heavy metals were analyzed by atomic absorption spectrophotometry (IL. 551) and carboxy-Hb, Met-Hb, Hb, O2 and CO2, blood gas analyzer (IL. 1301) and CO-oximeter (IL. 282). In urban group, PO2 and O2-Hb were significantly lower than in rural (p<0.01, p<0.03, respectively), and HCO3 and TCO2 were significantly higher than in rural (p<0.01, p<0.01, respectively). CO-Hb concentration was rather higher in the rural group than the urban (p<0.03), other Met-Hb was higher in urban group than in the rural (p<0.01). Lead and cadmium were also significantly higher in the urban group (p<0.03, p<0.02, respectively).
