Heavy Metal Concentrations in Soils and Plants Parts of Mangifera Indica L. Around An Economic Zone in The Municipality of Rosario, Cavite, Philippines

Abstract

INTRODUCTION

Contamination of heavy metal in industrial area has caused the interest in the scientific approach for their remediation. One of the approaches could be through phytoremediation which uses plant species to extract heavy metals from the contaminated soil.

METHODS

The study assessed the concentrations of selected heavy metals in soils and plant parts of Mangifera indica L. found around an economic zone in the Municipality of Rosario, Province of Cavite, Philippines. Soil and different plant part samples of M. indica were collected and subjected to atomic absorption spectrophotometry (AAS) and analyzed for lead (Pb), copper (Cu) and zinc (Zn).

RESULTS

Traces of metal were found in the soil samples of the study site, however, the concentrations were still within permissible level.

DISCUSSIONS

Generally, metal concentrations were found to be highest in matured leaves, followed by bark.
