GB/T 40226-2021

This standard specifies the technical requirements for detecting environmental microbial metagenomes using high-throughput sequencing, including sample collection, nucleic acid extraction, library preparation, sequencing, and data analysis. It is applied in environmental monitoring contexts such as assessing microbial diversity in soil, water, and air, as well as in public health and ecological risk evaluations. The standard ensures consistent and reliable detection methods for researchers and testing laboratories analyzing complex microbial communities in environmental samples.
