There is an increasing concern regarding elevated levels of Cr (VI) in the environment due
to its higher mobility and toxicity compared to the trivalent form. Anomalous hexavalent
chromium concentrations (up to 212 μg/L) were determined in irrigated groundwaters from
the wider area of Thiva Basin (central Greece), frequently exceeding the permissible limit for
human consumption (50 μg/L for total Cr). Based on the spatial distribution of Cr (VI) values,
two groups of groundwater samples were distinguished, possibly reflecting different natural …
