Because the Toxic Chemical Substances Control Act was amended to Toxic and Concerned Chemical Substances Control Act, it might face the sampling of pure chemical materials in the future. However, there was no standard sampling method in Taiwan. Therefore, this project classified chemicals by their status under the common temperature and pressure to search relative sampling technologies in the world, and collect foreign standard sampling methods. And then, the situations and requirements were analyzed to find out the framework of compiling the draft of the standard sampling method, according to domestic chemicals control policy and the experiences of sampling toxic chemicals. In addition, eight in-situ sampling practices and two technical observation and experience exchange sessions were held to make the draft meet the local demand. Finally, the final domestic standard sampling method was drawn up.
