Common occurrence of a positive ?53Cr shift in Central European waters contaminated by geogenic/industrial chromium relative to source values

Popis výsledku v původním jazyce

Carcinogenic effects of hexavalent chromium in waters are of concern in many countries worldwide. We explored Cr isotope systematics at 11 sites in the Czech Republic and Poland. Geogenic Cr pollution was associated with serpentinite bodies at former convergent plate margins, while anthropogenic Cr pollution resulted from electroplating, tanning, and chemical industry. Cr(VI) concentration in geogenic waters was less than 40 ppb. Anthropogenic waters contained up to 127,000 ppb Cr(VI). At both geogenicand anthropogenic sites, where known, the source of pollution had a low ?53Cr (<1 promile). ?53Cr of geogenic and anthropogenic waters was up to 3.9 and 5.8 promile, respectively. At both serpentinite-dominated and industrial sites, ?53Cr(VI)aq was shifted toward higher values, compared to the pollution source. At the industrial sites, this positive ?53Cr shift was related to Cr(VI) reduction, a process known to fractionate Cr isotopes. At geogenic sites, the origin of high ?53Cr(VI)aq i
