Soil quality. Detection of water soluble chromium(VI) using a ready-to-use test-kit method Ingestion-build-132972 BS 476-20:19871 Scope This Technical Report describes the procedure to screen soil samples to detect Cr(VI) using test kits based on water extraction of Cr(VI) in soil. The test kit approach in this method is designed to quickly screen soil samples using calibration to indicate the concentration level. A batch test at a liquid to solid ratio of 10 l kg, designated by ISO TS 21268 2, has been used in Japan for over 30 years to evaluate the risk of Cr(VI)
