Heavy Metal Concentration of Dumpsite Soil and Accumulation in Zea mays (corn) Growing in a Closed Dumpsite in Manila, Philippines
Leah Amor S. Cortez and Johnny A. Ching
Abstract—The study determined the heavy metal
concentrations (Cu, Zn, Cd and Pb) in dumpsite soil and
accumulation in Zea mays (corn) growing in the area. The
area of study is a closed dumpsite in Manila, Philippines
covered with rich vegetation and being used as agricultural
land. Soils and plants were sampled and analysed using atomic
absorption spectrophotometer (AAS). Concentrations of the
metals in the dumpsite soil and plant parts were found to be in
higher concentrations compared to normal farmland which
served as the control. Significant differences of heavy metals
accumulations were observed per plant parts. Traces of metals
were found in highest concentrations in the roots of all studied
plants. Pb was found to be the only metal in plant parts
exceeding the permissible limit given by WHO/FAO. The
findings suggest that further study and proper legislation on
the use of dumpsite soils must be taken into consideration.
Index Terms—Cadmium, corn, copper, lead, zinc.
