According to chemist Jennifer Tamayo, of the DOST’s Forest Products Research and Development Institute (FPRDI) in Los Baños, Laguna, she found out that tree barks could trap ions of lead and chromium present in the wastewater of steel galvanizing plants.


Lead and chromium pose health hazards because they cause biological mutation and kidney and liver cancer, respectively.
