Total organic carbon in soils from East Chicago, Indiana, USA in 2017/2018

The total organic carbon (TOC) content was analyzed for each sample, with the exception of 5 samples. A ceramic sample boat was filled with about 0.2 g of soil and combusted at 900 °C with a Shimadzu Total Organic Carbon Analyzer (TOC-V Series) and Solid Sample Module (SSM-5000A). The measured TOC was divided by the initial sample mass and reported as a percentage.
