1. A method for treating an object with chlorine dioxide gas while minimizing chlorine-containing residue on the object, comprising contacting the object with chlorine dioxide gas while exposing the object to less than 1000 lux of light, wherein the chlorine dioxide gas is generated at less than 100
1. A method for treating an object with chlorine dioxide gas while minimizing chlorine-containing residue on the object, comprising contacting the object with chlorine dioxide gas while exposing the object to less than 1000 lux of light, wherein the chlorine dioxide gas is generated at less than 1000 lux of light, the object comprises a raw agricultural product, the chlorine dioxide concentration adjacent the object during said treating step is 5 mg/L or less, and the chlorine-containing residue comprises chlorate, perchlorate, or a combination thereof, wherein the treating step comprises treating the object at a humidity of 70% or less. 2. The method of claim 1, wherein said exposing step comprises exposing the object to less than 200 lux of light. 3. The method of claim 1, wherein the chlorine dioxide concentration adjacent the object during said treating step is 2 mg/L or less. 4. The method of claim 1, further comprising the step of generating the chlorine dioxide gas by mixing dry particles of a chlorine dioxide precursor and a proton generating species. 5. The method of claim 1, wherein the chlorine dioxide gas is generated by mixing a sodium chlorite solution and hydrochloric acid solution. 6. The method of claim 1, wherein the total amount of chlorate and perchlorate formed on the surface of the object from said contacting step is 190 μg/kg of the object or less. 7. The method of claim 1, wherein the total amount of chlorate formed on the surface of the object from said contacting step is 160 μg/kg of the object or less. 8. The method of claim 1, wherein the total amount of perchlorate formed on the surface of the object from said contacting step is 30 μg/kg of the object or less. 9. The method of claim 1, wherein the raw agricultural product includes a fruit, a vegetable, or a combination thereof. 10. The method of claim 1, wherein the object is contacted with chlorine dioxide in a substantially dark or dark environment. 11. The method of claim 1, wherein the chlorine dioxide gas is generated in situ. 12. A method for treating an object with chlorine dioxide gas while minimizing chlorine-containing residue on the object, comprising contacting the object with chlorine dioxide gas while exposing the object to less than 1000 lux of light, wherein the chlorine dioxide gas is generated at less than 1000 lux of light, the chlorine dioxide adjacent the object during said treating step has an initial concentration of 5 mg/L or less, the concentration of chlorine dioxide gas adjacent the object after said treating step is less than the initial concentration of chlorine dioxide, and the chlorine-containing residue comprises chlorate, perchlorate, or a combination thereof, wherein the treating step comprises treating the object at a humidity of 70% or less. 13. The method of claim 12, wherein the object consumes at least a portion of the chlorine dioxide gas during said treating step. 14. The method of claim 12, wherein said exposing step comprises exposing the object to less than 200 lux of light. 15. The method of claim 12, wherein the chlorine dioxide concentration adjacent the object during said treating step is 2 mg/L or less. 16. The method of claim 12, further comprising the step of generating the chlorine dioxide gas by mixing dry particles of a chlorine dioxide precursor and a proton generating species. 17. The method of claim 12, wherein the chlorine dioxide gas is generated by mixing a sodium chlorite solution and hydrochloric acid solution. 18. The method of claim 12, wherein the total amount of chlorate and perchlorate formed on the surface of the object from said contacting step is 190 μg/kg of the object or less. 19. The method of claim 12, wherein the total amount of chlorate formed on the surface of the object from said contacting step is 160 μg/kg of the object or less. 20. The method of claim 12, wherein the total amount of perchlorate formed on the surface of the object from said contacting step is 30 μg/kg of the object or less. 21. The method of claim 12, wherein the object comprises a raw agricultural product. 22. The method of claim 21, wherein the raw agricultural product includes a fruit, a vegetable, or a combination thereof. 23. The method of claim 12, wherein the object is contacted with chlorine dioxide in a substantially dark or dark environment. 24. The method of claim 12, wherein the chlorine dioxide gas is generated in situ.
