  • Publication number: 20220241768
    Abstract: The disclosure relates to a diagnosis method and diagnosis device of ecotoxicity of solid waste soil in a pesticide production site. The diagnosis method is as follows: performing multi-point distributed collection on solid waste soil of a to-be-diagnosed pesticide production site, and subsequently pretreating the connected soil sample; synchronously performing a first toxicity test, a second toxicity test and a third toxicity test on the pretreated solid waste soil by using the diagnosis device. The diagnosis device comprises a first test device, a second test device and a third test device. The method of the disclosure is used for synchronous diagnosis of ecotoxicity by utilizing multiple diagnosis methods, and therefore is high in diagnosis efficiency and high in accuracy rate.
