Human health risk assessment of the municipal solid waste landfill at Morretes

This paper presents the human health risk assessment of a municipal solid waste landfill, located at Morretes, Paraná State, Brazil, using the RBCA methodology. It was performed a deterministic risk assessment, considering three receptors and three exposure pathways: groundwater ingestion, exposure to surface soil and outdoor inhalation of vapors and particulates. The results showed higher values of risk and hazard indexes for the on-site receptor. It was also performed a probabilistic risk assessment in order to evaluate the effect of both body mass and water ingestion rate correlation and body mass and air inhalation rate correlation on the risk frequency distributions. The results showed that using the hypothesis of independence between the variables leads to a more conservative decisions.
