              risk posed by exposures to mixtures of DLCs. TEFs
            
            
              are used to obtain TEQ values for complex mixtures,
            
            
              assuming additive effects according to the equation
            
            
              below.
            
            
              TEQ=
            
            
              (Equation 1).
            
            
              Hence, the TEQ value is the sum of the concentrations
            
            
              of each congener multiplied by their respective TEFs
            
            
              and represents the overall TCDD toxic potency of a
            
            
              sample.
            
            
              All statistical tests were performed using Origin
            
            
              software (7.5, 2004) with a significant level of p<0.05.
