Repeated exposure to high levels can also irritate the skin, eyes, nose and mouth, and can cause liver damage and respiratory failure. Perc might cause effects at lower levels as well. Studies in laboratory animals indicate that exposures to high levels of perc can produce effects on the developing fetus that include altered growth, birth defects, and death.

Scientists have not yet determined whether perc exposures can cause such adverse effects in pregnant women as increased incidence of miscarriage or reproductive effects, affect women’s ferti
