Abstract
Environmental pollution by lead is suspected to be increasing, both in
the plants, soil, and water. The lead contamination in plants will spread
to livestock production and then to humans. The aim of the study was
to examine the level of lead contamination in the blood of cattle
associated with the level of contamination in the soil and water at the
location where the cattle were kept. Cattle blood samples were taken
by purposive sampling method in each Regency in Bali, accompanied
by soil and water samples from this location. Examination of cattle
blood, soil and water samples was carried out for the presence of lead
using the atomic absorption spectrometry (AAS) method, at the
Analytical Laboratory of Udayana University. The results of the
examination of 270 samples of cattle blood, obtained the results of 20
cattle exposed to lead with an average of 0.109 ± 0.080 ppm.
Examination of lead contamination at 20 exposed cattle farm locations
obtained lead content data of 0.239±0.136 ppm in soil and
0.192±0.894 in water, respectively. The level of lead contamination in
the soil and water are higher than that of cattle blood. Regression test
showed that lead levels in cattle blood can be a predictor of lead
contamination in soil and water. on the cattle farm. The conclusion is
the presence of lead heavy metal contamination in cattle blood can be
used as a bioindicator of lead heavy metal pollution in the soil and
drinking water environment.
