“…Esses limites também foram utilizados em avaliações de risco realizadas por Michels et al (2004) e Gonçalves & Lena (2013) referente a áreas contaminadas do estado de São Paulo e Minas Gerais, respectivamente. De modo diferente, nos estudos realizados por Chang et al (2004), Fan et al (2010) e Han et al (2016) em áreas localizadas na Ásia, o limite adotado para risco carcinogênico foi de 10 -6 . Observou-se, portanto, que a abordagem para efeitos carcinogênicos tem sido mais conservadora em outros países, seguindo o limite mais crítico de risco adotado pela United States Environmental Protection Agency (2017b).…”

“…This knowledge is useful for the development of risk assessment procedures (USEPA 1989). Accordingly, spatial interpolation models and quantitative assessments of the risk of contaminants affecting groundwater quality can be useful for describing soil and groundwater pollution characteristics and evaluating the effects of contaminants on the environment and human health (Wu et al 2006;Di Sante et al 2009;Fan et al 2010). Although a number of studies of the spatial distribution of soil pollution in contaminated industrial sites have been completed, limited data are available for conducting risk assessments for groundwater quality at contaminated sites in rapidly industrializing cities in China Chen et al 2011;Geng et al 2014).…”

Contamination from organic chemical plants can cause serious pollution of soil and groundwater ecosystems. To characterize soil contamination and to evaluate the health risk posed by groundwater at a typical organic chemical plant site in Chongqing, China, 91 soil samples and seven groundwater samples were collected. The concentrations of different contaminants and their three-dimensional distribution were determined based on the 3D-krige method. Groundwater chemistry risk index (Chem RI) and cancer risk were calculated based on TRIAD and RBCA models. The chemistry risk indices of groundwater points SW5, SW18, SW22, SW39, SW52, SW80, and SW82 were 0.4209, 0.9972, 0.9324, 0.9990, 0.9991, 1.0000, and 1.0000, respectively, indicating that the groundwater has poor environmental status. By contrast, the reference Yangtse River water sample showed no pollution with a Chem RI of 0.1301. Benzene and 1,2-dichloroethane were the main contaminants in the groundwater and were responsible for the elevated cancer risk. The cumulative health risk of groundwater points (except SW5 and SW18) were all higher than the acceptable baselines of 10(-6), which indicates that the groundwater poses high cancer risk. Action is urgently required to control and remediate the risk for human health and groundwater ecosystems.

“…Risk assessment involves quantification of human health impacts of contaminated groundwater through integrated consideration, including identification of the sources of risk agents, simulation of their transport and fate in porous media, assessment of human exposure, and analyses of the subsequent effects [ Nolan et al , 1997; Maxwell et al , 1998; Li , 2003; Maqsood , 2004; Darbra et al , 2008; Troldborg et al , 2009; Fan et al , 2010]. It is related to characteristics of contaminant transport and fate in subsurface and behavioral patterns of an individual or a population exposed to the pollutant [ Maxwell et al , 1998; Phan et al , 2010].…”

[1] Groundwater pollution has gathered more and more attention in the past decades. Conducting an assessment of groundwater contamination risk is desired to provide sound bases for supporting risk-based management decisions. Therefore, the objective of this study is to develop an integrated fuzzy stochastic approach to evaluate risks of BTEXcontaminated groundwater under multiple uncertainties. It consists of an integrated interval fuzzy subsurface modeling system (IIFMS) and an integrated fuzzy second-order stochastic risk assessment (IFSOSRA) model. The IIFMS is developed based on factorial design, interval analysis, and fuzzy sets approach to predict contaminant concentrations under hybrid uncertainties. Two input parameters (longitudinal dispersivity and porosity) are considered to be uncertain with known fuzzy membership functions, and intrinsic permeability is considered to be an interval number with unknown distribution information. A factorial design is conducted to evaluate interactive effects of the three uncertain factors on the modeling outputs through the developed IIFMS. The IFSOSRA model can systematically quantify variability and uncertainty, as well as their hybrids, presented as fuzzy, stochastic and second-order stochastic parameters in health risk assessment. The developed approach haw been applied to the management of a real-world petroleum-contaminated site within a western Canada context. The results indicate that multiple uncertainties, under a combination of information with various data-quality levels, can be effectively addressed to provide supports in identifying proper remedial efforts. A unique contribution of this research is the development of an integrated fuzzy stochastic approach for handling various forms of uncertainties associated with simulation and risk assessment efforts.Citation: Zhang, X., and G.
