water (0.192±0.894 ppm at the farm location than in cattle blood
(0.109 ± 0.080 ppm). Regression test shows that lead heavy metal
content in soil and drinking water is significantly (p<0,05) associated
with lead content in cattle's blood (Table. 2 and 3).

In general, lead heavy metal contamination into the body of animals
and humans is through the oral, respiratory, and skin routes, but most
enter through the orally in the form of food and drinking water. The
entry of particles through absorption in the intestine is a small particle.
Not all the lead heavy metals which enter the body can stay in the
body. About 5% of the amount swallowed will be absorbed by the
digestive tract. Likewise, about 5% that is absorbed through inhalation
will stay in the body [11]. The lead heavy metal contamination
damages cells / tissues through oxidative stress mechanism [12]. The
tissue most sensitive to heavy metal contamination is the liver [13].
Sources of lead heavy metal pollution can come from the soil and
water environment [14]. Plants that grow in a polluted environment will
