5.13 SWIMMING DERMAL CONTACT


    The swimming dermal contact exposure pathway is based on the same dermal exposure model used for the shower dermal contact exposure pathway. Default parameter values for the swimming dermal contact exposure pathway are given in Table 5.13.

    Note that the product of swimming event time and swimming frequency is equal to an average daily swimming time of 0.033 hours, consistent with the initial MEPAS daily swimming time.
