Sediment Profile and Fluxes of Mercury and Methyl Mercury in Weihe Watershed in Henan, China
Abstract Sediment core samples were collected from the Weihe River in February and August 2013. Cores were sectioned and analyzed for total Hg (THg) and methyl mercury (MeHg). THg in sediment cores ranged from 156 to 282 ng $ g^{−1} $ in February, and from 172 to 300 ng $ g^{−1} $ in August. MeHg co...

| 520 | |a Abstract Sediment core samples were collected from the Weihe River in February and August 2013. Cores were sectioned and analyzed for total Hg (THg) and methyl mercury (MeHg). THg in sediment cores ranged from 156 to 282 ng $ g^{−1} $ in February, and from 172 to 300 ng $ g^{−1} $ in August. MeHg concentrations ranged from 0.80 to 3.11 ng $ g^{−1} $ in both seasons. Results showed that the diffusive fluxes were up to two orders of magnitude lower than the in situ benthic fluxes. Fluxes of MeHg measured in in situ experiments in August were positively correlated with %$ {\text{SO}}_{4}^{2 - } %$ (r = 0.930). THg and MeHg release were not strongly correlated with TOC in February. Patterns of MeHg flux differed greatly depending on oxidation–reduction potential (Eh) (r > 0.70) conditions in the two seasons. | ||

Cores were sectioned and analyzed for total Hg (THg) and methyl mercury (MeHg). THg in sediment cores ranged from 156 to 282 ng $ g^{−1} $ in February, and from 172 to 300 ng $ g^{−1} $ in August.

Cores were sectioned and analyzed for total Hg (THg) and methyl mercury (MeHg). THg in sediment cores ranged from 156 to 282 ng $ g^{−1} $ in February, and from 172 to 300 ng $ g^{−1} $ in August. MeHg concentrations ranged from 0.80 to 3.11 ng $ g^{−1} $ in both seasons. Results showed that the diffusive fluxes were up to two orders of magnitude lower than the in situ benthic fluxes. Fluxes of MeHg measured in in situ experiments in August were positively correlated with %$ {\text{SO}}_{4}^{2 - } %$ (r = 0.930). THg and MeHg release were not strongly correlated with TOC in February. Patterns of MeHg flux differed greatly depending on oxidation–reduction potential (Eh) (r > 0.70) conditions in the two seasons.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">THg</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">MeHg</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Benthic chamber experiments</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Fluxes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jiang, Lingyan</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Dingyong</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Luo, Xu</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Bulletin of environmental contamination and toxicology</subfield><subfield code="d">New York, NY : Springer, 1966</subfield><subfield code="g">95(2015), 1 vom: 03.

Sediment Profile and Fluxes of Mercury and Methyl Mercury in Weihe Watershed in Henan, China |
| abstract |
Abstract Sediment core samples were collected from the Weihe River in February and August 2013. Cores were sectioned and analyzed for total Hg (THg) and methyl mercury (MeHg). THg in sediment cores ranged from 156 to 282 ng $ g^{−1} $ in February, and from 172 to 300 ng $ g^{−1} $ in August. MeHg concentrations ranged from 0.80 to 3.11 ng $ g^{−1} $ in both seasons. Results showed that the diffusive fluxes were up to two orders of magnitude lower than the in situ benthic fluxes. Fluxes of MeHg measured in in situ experiments in August were positively correlated with %$ {\text{SO}}_{4}^{2 - } %$ (r = 0.930). THg and MeHg release were not strongly correlated with TOC in February. Patterns of MeHg flux differed greatly depending on oxidation–reduction potential (Eh) (r > 0.70) conditions in the two seasons. © Springer Science+Business Media New York 2015 |
