Cadmium and hypertension.

Hypertension is a very common and important disease of modern civilised life. There are comflicting reports about cadmium, a trace element in the genesis of essential hypertension. The present study was conducted to estimate the cadmium levels in whole blood in the normal group of thirty subjects who were normotensive and the same was compared to that of thirty hypertensive patients and the levels were found to be statistically significant (p < 0.05).

Sources of lead exposure in urban slum school children.

A school based study was undertaken to trace various sources of lead exposure in urban slum children. Two cases with elevated venous blood lead (PbB) levels were detected and confirmed in 100 consecutive Bombay school children, referred to a hospital school clinic for clinical pallor. A common source of lead exposure in one suburb, was implied by the significantly higher PbB levels here. Systematic family and environmental studies identified the source was a nearby factory manufacturing lead storage batteries. Similar studies for the other index case traced the source to the dust produced by small scale foundries and secondary lead smelters. This study indicates that large scale screening studies are necessary to establish the magnitude and epidemiology of this problem in Bombay.
