Abstract

Introduction: This study aims to determine the concentration of heavy metals in cockles (A.granosa) and river water during wet and dry seasons and its potential health risk. Besides, to characterize the physiochemical parameter in landfill leachate. Cockles are one of bioindicator of aquatic ecosystem due to its ability to accumulate metal. From the previous study, season of sampling is one of factor known to influence metal concentration and accumulation in this organism. Methodology: The study was conducted at commercially cultured cockle bed, coastal area of Pantai Remis, Jeram which is located approximately 8km away from Jeram Sanitary Landfill and the nearest river at cockles‟ bed, namely Sembilang River. The study design used was cross sectional study. 18 samples of cockles, 12 samples of surface water and 3 samples of raw leachate were taken for analysis selected heavy metal using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Results: The analysis shows there was a little variation in heavy metal concentration between location and season for surface water and cockles samples. For raw leachate samples, 8 parameters which are BOD, COD, Cr, Fe, Ni, Zn and As were over the standard limit allowed by the Environmental Quality (Control of Pollution from Solid Waste Transfer Station and Landfill) Regulations 2009. Target Hazard Quotient (THQ) value was found lower for all heavy metal and show no potential risk. Conclusion: There is significant different of concentration of heavy metal in cockles between wet and dry season. However, it is not solely the seasonal variation as factor that influences the concentration of heavy metal. Consumption of the cockles in Jeram can be concluded as safe as the level of selected heavy metal is low enough and low THQ.
