5.24 SHORELINE EXTERNAL

    Shoreline exposure occurs when an individual is near contaminated shoreline sediments during periods of shoreline recreational activity. Parameters for this pathway include frequency of shoreline use, length of time in shoreline activities, and a shore width factor to account for the shoreline being less than infinite. Default parameter values for the shoreline external exposure pathway are given in Table 5.23.

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