EFFECTS OF URBAN WASTE ON HEAVY METALS CONCENTRATION IN CARICA PAPAYA LINN AND SOIL IN ENEKA DUMPSITE, PORT HARCOURT, RIVERS STATE, NIGERIA
The study examined the heavy metal concentrations in the tissues of Carica papaya (CP) tissues and soil in Eneka Dumpsite, Port Harcourt, Nigeria. A transect of 100 m x 300 m was laid from the center of the dumpsite. In the transect a 20 m x 20 m quadrat was established at 10 m, 20 m, 50 m, and 3...

| Summary: | The study examined the heavy metal concentrations in the tissues of Carica
papaya (CP) tissues and soil in Eneka Dumpsite, Port Harcourt, Nigeria. A transect of 100
m x 300 m was laid from the center of the dumpsite. In the transect a 20 m x 20 m quadrat
was established at 10 m, 20 m, 50 m, and 300 m (control) from the dumpsite whereby the
soil samples and CP tissues (leaf, fruit and root) were collected. Standard laboratory
techniques were used to determine the heavy metals in the soil samples and CP tissues.
Results showed that heavy metals in CP and soil decreased with increasing distance from
the dumpsite. Fe, Pb and Cu in CP tissues varied significantly with distance. In conclusion,
there is accumulation of heavy metals in CP around dumpsite and human consumption of
such CP should be reduced or totally avoided. |
