ABSTRACT
Lead (Pb) exposure is a global public health concern with serious negative health effects, especially among children. In 2012, there was an epidemic of Lead (Pb) poisoning in children related to the processing of Lead-rich ore for gold extraction in Nigeria. In the Philippines, Agusan del Sur is one of the provinces with booming gold mining industry, and Lead (Pb) contamination of creeks near the mining sites is alarmingly high. To remediate mining pollution, phytoremediation is one of the options employed. Phytoremediation can help decontaminate soil or water by inactivating metals in the rhizosphere or translocating them in the aerial parts. This study aims to search for hyperaccumulator plants that can be used to remediate Lead (Pb) contamination in creeks contaminated with mining waste water.
Three (3) sampling sites were selected (upstream, midstream and downstream). These sampling sites are located near mining sites in Rosario, Agusan del Sur. Water, Soil, and Plant samples were collected from the 3 sampling sites and were assayed for its Lead (Pb) concentration. The Lead (Pb) concentration of plant samples are then correlated to the physico-chemical parameters: Water pH, Water Temperature, Water Current, and the Lead concentration in water.
Based on the analysis of the Lead (Pb) concentration of each sample plant, Echinochloa sp. has the most potential as Lead (Pb) hyperaccumulator, accumulating 88.27 µg/g dry samples on average; while Ottelia alismoides
