The major purpose of the present investigation was to study the effects of
different concentrations of residual chlorine on serum iron related parameters in
rats. Feeding male rats with water containing 80 ppm of residual chlorine daily for
5 days reduced serum levels of ceruloplasmin, copper, iron and hemoglobin by
approximately 27%,23%,6% and 4%, respectively. Higher reductions in serum
ceruloplasmin (35%), copper (50%), Fe (17%) and hemoglobin (14%) were
observed when rats were given water containing 160 ppm of residual chlorine daily
for 5 days. The total iron binding capacity (TIBC) level was elevated by 9 and/or
13 percent respectively. Daily feeding of rats for 1 0 days with water containing 160
ppm residual chlorine caused significant reductions in serum levels of ceruloplasmin
(50%), copper (54%) iron (17%) and hemoglobin (17%). Serum TIBC was
elevated by 25%. Long term effects of residual chlorine on the above parameters
were also investigated. It can therefore be .concluded that residual chlorine in
drinking water may interfere with iron metabolism. The relationship between the
occurrence of anemia and residual chlorine toxicity has been discussed.
