| Summary: | The Dasmarinas River is located along the Aguinaldo Highway where
some of its tributaries are located to industrial areas. It is therefore more or less
exposed to industrial wastes such as lead. The waters or the Dasmarinas had been
subjected to some biochemical tests to determine its quality.
In this study, the researchers tested if mosses can indicate the presence of
lead in water. Through the use of Flame Atomic Absorption Spectrophotometry,
the researchers measured the amount of lead present in the upstream and
downstream of the river. One Factor- Analysis of Variance and Two-way
Analysis of Variance were used as a statistical method to compare the amount of
lead present considering the three replicate samples that are collected in each of
the sites.
The statistical analysis showed that there is a significant difference in the
amount of lead present in upstream and downstream of the Dasmarinas River.
Mosses, therefore can be used as bioindicators of lead in water. |
