CHROMIUM LEACHING FROM ROAD CEMENT-SOILS IN THE CONTEXT OF FOREST ENVIRONMENT PROTECTION

Keywords: forest environment, road, cement-soil, leaching, chromium
Abstract: The research was aimed to determine the chromium content of various types of cement and a selected type of sand and to define the extent to which chromium is washed from these materials and from hardened cement-soils. Samples of cement-soils with different cement contents were investigated both in an undisturbed and a crushed state (to simulate a worn foundation). It was found that the chromium content of sand was low (about 15 mg . kg-1) and the various cements contained similar amounts of the metal (50–60 mg . kg-1). Chromium was washed from the cements to a similar degree – its concentration in eluats was 20–25 mg . dm-3. The concentration of chromium in the eluats from cement-soils approximated 1.0 mg . dm-3 and was slightly higher for crushed samples than for undisturbed samples. The total chromium content of cements was within the permissible levels of chemical contaminants in the soil. The concentration of chromium in the eluats from cement-soils was higher than its permissible concentration in sewage discharged to the ground.
