  2. Vaporized hydrogen peroxide - Wikipedia

    en.wikipedia.org/wiki/Vaporized_hydrogen_peroxide

    VHP is produced from a solution of liquid H 2 O 2 and water, by generators specifically designed for the purpose. These generators initially dehumidify the ambient air, then produce VHP by passing aqueous hydrogen peroxide over a vaporizer, and circulate the vapor at a programmed concentration in the air, typically from 140 ppm to 1400 ppm, depending on the infectious agent to be cleared.

    en.wikipedia.org/wiki/Fumigation

    Fumigation is a hazardous operation. Generally it is a legal requirement that the operator who carries out the fumigation operation holds official certification to perform the fumigation, as the chemicals used are toxic to most forms of life, including humans. [1] Post operation ventilation of the area is a critical safety aspect of fumigation.

    A U.S. soldier is demonstrating DDT hand-spraying equipment. DDT was used to control the spread of typhus-carrying lice. Spraying hospital beds with DDT, PAIGC hospital of Ziguinchor, 1973 Biomagnification is the build up of toxins in a food chain. The DDT concentration is in parts per million.

  5. Sulfuryl fluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfuryl_fluoride

    Sulfuryl fluoride is colorless and odorless, however, during the fumigation process, a warning agent called chloropicrin is first released into the building to ensure that no occupants remain. Tent fumigation is the most effective treatment for the extermination of known and unknown infestations of wood-destroying insects.

  6. Pesticide residue - Wikipedia

    en.wikipedia.org/wiki/Pesticide_residue

    Monitoring of pesticide residues in the UK began in the 1950s. From 1977 to 2000 the work was carried out by the Working Party on Pesticide Residues (WPPR), until in 2000 the work was taken over by the Pesticide Residue Committee (PRC). The PRC advise the government through the Pesticides Safety Directorate and the Food Standards Agency (FSA). [18]

    The reagents used depend on the type of sample to be analyzed. Following this, the sample is put through a dispersive solid phase extraction cleanup prior to analysis by gas-liquid chromatography or liquid-liquid chromatography. Samples prepared using the QuEChERS method can be processed more quickly using a homogenization instrument.
