Figure 1 was taken from an unpublished report, DuPont Study No. AMR 4392-97, Dissipation of Dislodgeable Foliar and Soil Residues of Oxamyl Following Application of Vydate L Insecticide to Tomatoes in the USA - Season 1997-1998 . This study has been submitted to the EPA and the data were used to establish and verify re-entry intervals. Data from this study will be used to provide an example of the topics discussed throughout this article.

All tests shown in Fig. 5 have been carried out using commercial products, because the treatment must destroy not only active matter, but any other organic contained in the formulation as well. Unfortunately, very little information on the effects of adjutants in photocatalysis degradation is available because pesticides commercial formulations are usually patent protected. Fig. 5 summarizes tests carried out with 4 commercial pesticides. The initial TOC obtained fi-om adding 100 mL of Vydate (24% w/v oxamyl) to 247 L of water produced a TOC of almost 90 mg V of which only 37 mg L come from oxamyl, and the rest come from the formulation. Likewise, with 62 mL of Confidor (20% w/v imidacloprid) the initial TOC obtained is 130 mg V of which 21 mg L of TOC are imidacloprid adding 82 mL of Rufast (15% w/v of acrinathrin), TOC was almost 50 mg/L, of which only 29 mg/L are from acrinathrin a 0.33 mL/L Tamaron 50 (methamidophos 50% w/v)/water solution has a TOC of 100 mg/L (only 28 mg/L are from methamidophos).
