Overview
Yozukmaz and colleagues measured ten heavy metals in water, sediment, and Enteromorpha intestinalis from Kadin Creek in western Anatolia. This is in-scope lane a3 aquatic-bioaccumulation evidence and not bottled-water occurrence evidence.
Key numbers
The abstract states that ten heavy metals were measured in water, sediment, and algal samples: aluminum (Al), chromium (Cr), Mn, nickel (Ni), Cu, Zn, arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb).
Table 2 reports analytical LOD values in ug/L of 0.06 for Al, 0.02 for Cr, 0.11 for Mn, 0.82 for Ni, 0.05 for Cu, 0.003 for Zn, 0.05 for As, and 0.06 for Cd, with the remaining listed in the table as printed by the source.
Table 3 reports heavy-metal concentrations in Enteromorpha intestinalis on a dry-weight basis (mg/kg dw), with n = 20 for algal samples; the source also reports n = 12 water samples and n = 3 sediment samples.
The abstract states that bioconcentration in algae ranked, relative to water, Al > Cu > As > Zn > Cr > Mn > Ni > Pb > Hg > Cd, and relative to sediment, Hg > Cd > As > Zn > Pb > Cu > Ni > Mn > Cr > Al.
Methods (brief)
The study sampled Kadin Creek seasonally in 2011 and 2012 and measured metals after mineralization by ICP-MS. Operating conditions for the Agilent 7700X ICP-MS are reported in Table 1. The study compares concentrations across water, sediment, and algal tissue to assess bioindicator performance and bioconcentration patterns.
