Abstract

The distribution of lead at three distances from the highway in Laguna has been determined by analysis of groundwaters and stems of Ipomoea aguatica taken from three study areas. Water samples revealed that there is a decline in lead levels with increasing distance from the highway. However, plant samples showed higher lead levels at 40 m than at five meters from the highway. It appears that the influence of wind direction of lead levels is not minimal.

The lead concentrations of water at different age of pipe installations and of stems at three portions of the plant were also determined. Results indicated an increase in lead levels from older pipes, while there was a decrease in lead concentrations from top to bottom portions of the plant.

The effect of time of sampling for water and plant samples were analyzed .  Collection of water samples after several days of raining showed increase in lead levels, while plant samples obtained in one day suggest no difference in load concentrations.  The significance of results was discussed.
