In addition, the chemicals being released in Illinois have been documented as potentially causing various health effects (lEPA, 1992). Some chemicals are considered known human carcinogens (KHC), probable human carcinogens (PHC), teratogens, reproductive toxicants and/or fetal toxicants. The totals for these categories are not exclusive; one chemical may fall into more than one category. lEPA grouped TRI chemical releases by these human health effect categories for the purpose of analysis. Figure demonstrates the overall trend in the release of chemicals for the five health effects groups. When evaluating such health category data, it is important to remember that exposure to these toxic chemicals depends on a number of site- specific environmental conditions in the geographic area of release, and that these issues are not addressed in TRI. The releases in these health effects groups have fluctuated since 1987. The increased releases during 1988-1989 may be explained
