“…Probabilistic techniques such as Monte Carlo analysis have been used to characterize the health risks of populations exposed to various chemicals since about 1990 (Cassin et al, 1998;Bogen et al, 1997;Chan et al, 1997;Carrington et al, 1996;Crouch, 1996aCrouch, , 1996bDel Pup et al, 1996;Lipfert et al, 1996;Adams et al, 1994;Finley et al, 1993Copeland et al, 1993Copeland et al, , 1994McKone, 1994;Lloyd et al, 1992;McKone & Bogen, 1992;Paustenbach et al, 1991Paustenbach et al, , 1992Thompson et al, 1992;Whitmyre et al, 1992aWhitmyre et al, , 1992bBurmaster & Von Stackelberg, 1991;Eschenroeder & Faeder, 1988;Fiering et al, 1984). By the late 1990s, many papers had been published that showed that probabilistic methods represent a significant improvement over deterministic approaches Richardson & Allan, 1996;Frey & Rhodes, 1996;Cohen et al, 1996;Cullen, 1994;Finley et al, 1993Thompson et al, 1992;McKone & Bogen, 1991;Paustenbach et al, 1991).…”
