| Summary, etc. | This study focuses on the assessment of the risks to human health associated with the exposure to heavy metals bioaccumulation in kangkong (Ipomea aquatica) grown along the Laguna Lake along lakeshore of Taytay, Rizal. Samples of water and plant were collectedin three selected sampling sites along the shores of the lake with land uses such as agricultural, industrial and residential last December 2015, almost two weeks after the Typhoon Nona (International Name: Melor). Coordinates of sampling site and points location were recorded using Global Positioning System (GPS) and plotted in Geographic Information System (GIS) digital maps. Heavy metal analyses for arsenic (As), cadmium (Cd) and lead (Pb) were carried out by an accredited laboratory using the Inductively Coupled Plasma Spectrometry (ICPS) and Hydride Vapor Generator that is attached to an Atomic Absorption Spectrophotometry System (HVG-AAS). The potential of hydrogen (pH) in water was measured using pH meter. The data of pH, As, Cd and Pb concentrations of water is all sampling sites were within the water quality and prescribed safe levels for Class C waters set by the DENR. The Pb concentrations of the edible parts of the plants in S3 (residential land) exceeded the maximum permissible limit for lead (0.3 mg/kg) for leafy vegetables set by Codex Alimentarius Commission for human consumption. Estimates of health risks associated with plant consumption were summarized according to non-carcinogenic and carcinogenic health effects. Non-carcinogenic Health Quotient (NHQ) values of the three heavy metals showed that lead is the most urgent pollutant of concern in terms of adverse health effects from risks associated with plant consumption from two sampling sites (S2 and S3). Likewise, hazard index in S2 and S3 indicated unacceptable adverse health risks with values .1.0. In contrast, potential carcinogenic effects of arsenic (Class A human carcinogen through oral route of exposure) levels are low. |
