Phytoaccumulation of heavy metals and pesticide residues in the leaves of twelve selected malaueg medicinal plants
Abstract
The study aimed to determine the phytoaccumulation of heavy metals and pesticide residues in the leaves of twelve selected medicinal plants commonly used by the Malaueg community of Rizal, Cagayan, namely: Tabernaemontana pandacaqui Lam. (bicarud), Alocasia sp (biga), Imperata cylindrica (L.) Raeusch (gabut), Curcuma sp (kunig), Ficus septica Burm. f. (liwliw), Cymbopogon citrattus (DC.) Staph (lubigan), Hyptis brevipes Poit. (matalagdaw), Chromolaena odorata (L.) R.M.King & H.Rob. (NPA), Peperomia pellicida (L.) Kunth. (pansit – pansitan), Mollugo sp (papait), Eleusine indica (L.) Gaertn. (tarattut), and Ehretia microphylla Lam (wild tea). Specifically, it aimed to (a) determine the heavy metal content of the soil and the leaves of the twelve selected Malaueg medicinal plants, (b) determine the pesticide residue content of the soil and the leaves of the twelve selected Malaueg medicinal plants and (c) determine the phytoaccumulation potential of the twelve selected Malaueg medicinal plants. The non – accumulation of heavy metals and pesticide residues by the plants points out to the safety of the leaves of the plants for use in preparation of products like personal and home care products, herbal ointment, cream, & lotion, functional food, etc. It is recommended that a test for the presence of other pesticide residues like organophosphates, carbamates, and the like be also conducted.
