also be polluted. If the plant is eaten by cattle, the cattle will be
contaminated by lead heavy metal. This is evidenced in intensive
farming of dairy cows; in fact, their blood is positive for lead heavy
metal [15].
Regression analysis showed a relationship between levels of lead
heavy metal in the cattle blood and levels in soil and drinking water at
the farm site. This reinforces the notion that cattle can be a bio-
indicator of pollution in an environment. It is reported that every animal
has a sensitivity to heavy metal exposure, so it is called a bioindicator
of the level of pollution in its environment. Several types of animals
have been reported as bioindicators of environmental pollution,
including buffalo [16], cattle, sheep, and camels [17, 18] and forest
anoa [19]. The results showed that cattle can also be bioindicators of
environmental for the lead pollution level.
4 CONCLUSIONS
The presence of lead heavy metal contamination in cow blood can be
used as a bioindicator of lead heavy metal pollution in the soil and
drinking water environment. Cows are very sensitive to the presence
of environmental pollution around them, so that pollutants can
immediately enter their blood circulation system.
