Table 7B. The reported cumulative acres treated in California from 1991 to 1998 with pesticides on the toxic air contaminants list. These pesticides are the currently registered active ingredients listed in the California Code of Regulations, Title 3, Division 6, Chapter 4, Subchapter 1, Article 1, Section 6860. Use includes primarily agricultural applications. The total for acres treated is less than the sum of acres treated for all active ingredients because some products contain more than one active ingredient. Data from the Department of Pesticide Regulation's Pesticide Use Reports with probable errors removed.
