Measurement of Water Soluble Organic Carbon in Particulate Matter 2.5

Atmospheric particulate matter 2.5 (PM2.5) is composed of primary particles emitted directly into the atmosphere by a source, and secondary particles generated by chemical reactions in the atmosphere. In 2009, governmental environmental standards on fine particulate matter were established in Japan. Since their establishment, findings related to sources of fine particulate matter and mechanisms of secondary particulate generation have been deliberated and control measures discussed. Particular emphasis has been placed on measurements for the concentration of water soluble organic carbon (WSOC) in PM2.5, which is linked to mechanisms of secondary particulate generation. In this article, we will describe using the Shimadzu TOC-L total organic carbon analyzer to measure the WSOC content in diesel particulate matter based on the measurement method issued by Japan's Ministry of the Environment.
