P. H. Howard, ed.. Handbook of Environmental Fate andExposure Datafor Organic Chemicals, Vol. Ill, Pesticides, Lewis PubHshers, Chelsea, Mich., 1991. Provides chemical and physical properties of 70 pesticide active ingredients reviews data on environmental fate and exposure potential, with general references.

Some data submitters were concerned about whether the supplemental files would be archived along with the data, and whether the supplemental files would be subject to Freedom of Information Act (FOIA) requests. OPP expects to maintain the CD provided as the electronic data submission, and archive the supplemental files on CD along with the rest of the electronic data submission. However, the official archive format at the present time is paper, and the supplemental files duplicate material in the paper submission. Supplemental files may be released upon FOIA requests after the first registration for the pesticide active ingredient, subject to the requirements of FIFRA 10(g), which include an affirmation statement from the requestor and a notice to the data owner, and exclude any FIFRA CBI. 

Moreover, the EPA Office of Pesticides and Toxic Substances has grouped pesticide active ingredients into three different categories based on production and exposure potential. One of EPA s three categories consists of "low" production pesticides. The Agency defined this category as an annual production volume of 25,000 pounds or less. 

The majority of samples taken in the FDA monitoring program are from imported foods, which constitute approximately two thirds of all the samples taken. Imports are typically sampled at the point of entry into the U.S., while domestic samples are frequently collected close to the production source or at the wholesale level. Samples are usually analyzed using multiresidue techniques capable of the detection of approximately 200 pesticide active ingredients as well as several other pesticide metabolites, impurities, and alteration products.

In 1995, EPA reduced the REI for certain "low-risk" pesticide active ingredients from 12 to 4 hours. Registrants may apply to reduce the REI for products that contain these active ingredients and meet certain other criteria. Check the product label for Class III and IV products to see if a four-hour REI has been obtained. 

The total amount of pesticide active ingredient apphed to the site, including all previous applications, must not exceed the rate and fine-quency allowed on the labeling. 

A residue is the part of a pesticide that remains in the environment for a period of time following application or a spill. Pesticides usually break down into harmless components after they are released into an environment. The breakdown time ranges from less than a day to several years. The rate of pesticide breakdown depends primarily on the chemical structure of the pesticide active ingredient. The rate of pesticide breakdown also may be affected by environmental conditions at the release site, such as ... 

Of the 700-800 U.S.-registered pesticidal active ingredients, only a relatively small number (2) have leached to groundwater. Unfortunately, some of these chemicals are or were among the major pesticides used in American agriculture (2). Three of these will be discussed in the following section, with special attention to soil characteristics that may have influenced movement.
