§ 25721. Level of Exposure to Chemicals Causing Cancer.
(a) For the purposes of the Act, “level in question” means the chemical concentration of a listed chemical for the exposure in question. The exposure in question includes the exposure for which the person n the course of doing business is responsible, and does not include exposure to a listed chemical from any other source or product.
(c) For purposes of Section 25249.10(c) of the Act, the level of exposure to a chemical listed as causing cancer, assuming lifetime exposure at the level in question, shall be determined by multiplying the level in question (stated in terms of a concentration of a chemical in a given medium) times the reasonably anticipated rate of exposure for an individual to the given medium of exposure measured over a lifetime of seventy years.
Subpopulation | Water liters/day | Air cubic meters/day |
---|---|---|
Man (18 + years of age) | 2 | 20 |
Woman (18 + years of age) | 2 | 20 |
Woman with conceptus | 2 | 20 |
Adolescent (10-18 years of age) | 2 | 20 |
Child (2-10 years of age) | 2 | 15 |
Infant (0-2 years of age) | 1 | 4 |
(3) For workplace exposures, the exposed worker inhales ten cubic meters of workplace air per eight-hour day, forty hours per week, fifty weeks per year over a forty-year period. The exposed individual from the general population who occasionally enters a workplace inhales 1.25 cubic meters of workplace air for one hour per month for a seventy-year lifetime.
(4) For exposures to consumer products, lifetime exposure shall be calculated using the average rate of intake or exposure for average users of the consumer product, and not on a per capita basis for the general population. The average rate of intake or exposure shall be based on data for use of a general category or categories of consumer products, such as the United States Department of Agriculture Home Economic Research Report, Foods Commonly Eaten by Individuals: Amount Per Day and Per Eating Occasion, where such data are available.
