This specification specifies the technical requirements for sample pretreatment for genetic toxicity testing of organic pollutants in the environment. This specification is divided into five parts: Part 1 Pretreatment of atmospheric inhalable particulate matter samples Part 2 Pretreatment of surface water and wastewater samples Part 3 Pretreatment of non-aqueous liquid waste samples Part 4 Pretreatment of soil and sediment samples Part 5 Pretreatment of solid waste samples The definitions given in the specification are limited to use within this specification and are not universal. This specification does not provide a comprehensive explanation of the quality control and operational safety of sample pretreatment, but only explains specific issues. Other issues should comply with the relevant principles of qualified laboratory standards. The quality control principles of this specification are all based on the premise that the genetic toxicity detection system itself is normal. This specification does not provide a separate record form, and the record of the sample pretreatment process should comply with the principles of conventional analysis and testing. This specification applies to non-volatile organic matter in atmospheric inhalable particulate matter, but not to gaseous and semi-gaseous organic matter in atmospheric inhalable particulate matter.
