Environmental health risk assessment of manganese and cadmium in the ground water around Cipayung Landfill in Depok, Indonesia

Abstract

Abstract The existence of landfill is a risk to release various metals into the environment, such as Manganese (Mn) and Cadmium (Cd). Mn and Cd can cause serious and toxic effect for health if excessive intake. This study was conducted to identify the health risks of Cd and Mn intake in Cipayung Landfill Depok. The samples were 104 respondents and 66 ground water samples at a radius of 0-500 meters from the landfill. Cd and Mn Measurement in the ground water used atomic absorption spectrophotometry. Health risk analysis was determined based on hazard identification, dose-response assessment, exposure assessment and risk characterization. Mn and Cd concentration were 0.06-0.84 mg/L and <0.001 mg/L, respectively, while the average daily consumption of ground water was 2.18 L. Mn and Cd Chronic Daily Intake (CDI) were 0.008 mg/kg/day and 0.00005 mg/kg/day, respectively. Mn and Cd Hazard Quotient (HQ) were not more than 1 with maximum Mn and Cd HQ, 0.2 and 0.08, respectively. It can be concluded that the concentration of Mn and Cd in groundwater consumption in the community around the Cipayung landfill is categorized as not having risk to health, even though there are 9 ground water samples with Mn concentrations exceeding 0.4 mg/L.
