The aim of the present study was to investigate the differences of methylmercury (MeHg) formation and distribution between mariculture (aquaculture) sediments (MS) and reference sediments (RS) collected from a site in Hong Kong.
Materials and methods
The MS and RS samples were split into four batches, three of which were spiked with HgCl
2
aqueous solution to a concentration of 0.8, ,2 and 8 mg k g
−1
in sediment samples SP1, SP2, and SP3, respectively, while the rest served as a control batch (referred to as C).
Results and discussion
The results showed that the highly Hg-polluted sediment produced greater amounts of MeHg. During the culture period, MeHg concentrations in sediments decreased over time. The decreasing percentage increased in the order of SP3 |

The aim of the present study was to investigate the differences of methylmercury (MeHg) formation and distribution between mariculture (aquaculture) sediments (MS) and reference sediments (RS) collected from a site in Hong Kong.

Results and discussion
The results showed that the highly Hg-polluted sediment produced greater amounts of MeHg. During the culture period, MeHg concentrations in sediments decreased over time. The decreasing percentage increased in the order of SP3 < SP2 < SP1, which might be due to the inhibition of MeHg degradation by high Hg concentrations. The mean value of MeHg concentrations and %MeHg of the total Hg (THg) in MS was significantly lower than those in RS, possibly due to the complexation of Hg with organic ligands, leading to lower Hg bioavailability for methylation bacteria. The distribution coefficient of THg (K
d
T) was relatively high in MS compared to RS, indicating that the former had a greater number of binding sites for Hg adsorption.
Conclusions
Methylmercury formation was inhibited in MS, probably due to increased complexation of Hg
2+
with organic matter and adsorption of Hg to MS. Furthermore, the mean value of K
d
T in MS was relatively high when compared to RS, which illustrates that MS sediments have more binding sites than RS for adsorption of Hg.</description><identifier>ISSN: 1439-0108</identifier><identifier>EISSN: 1614-7480</identifier><identifier>DOI: 10.1007/s11368-013-0719-x</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Adsorption ; Aquaculture ; Bioavailability ; Contaminated sediments ; Earth and Environmental Science ; Environment ; Environmental Physics ; Environmental science ; Marine ; Marine aquaculture ; Mercury ; Methylmercury ; Organic matter ; Pollutants ; Sec 2 • Physical and Biogeochemical Processes • Research Article ; Sediment pollution ; Sediment samplers ; Sediments ; Soil Science & Conservation</subject><ispartof>Journal of soils and sediments, 2013-08, Vol.13 (7), p.1301-1308</ispartof><rights>Springer-Verlag Berlin Heidelberg 2013</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c349t-283463ace684892688542d3b73941c8138493288328244b05b88a16fd41ec56b3</citedby><cites>FETCH-LOGICAL-c349t-283463ace684892688542d3b73941c8138493288328244b05b88a16fd41ec56b3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1007/s11368-013-0719-x$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1007/s11368-013-0719-x$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,780,784,27924,27925,41488,42557,51319</link.rule.ids></links><search><creatorcontrib>Liang, Peng</creatorcontrib><creatorcontrib>Lam, Cheung-Lung</creatorcontrib><creatorcontrib>Chen, Zhang</creatorcontrib><creatorcontrib>Wang, Hong-Sheng</creatorcontrib><creatorcontrib>Shi, Jian-Bo</creatorcontrib><creatorcontrib>Wu, Sheng-Chun</creatorcontrib><creatorcontrib>Wang, Wen-Xiong</creatorcontrib><creatorcontrib>Zhang, Jin</creatorcontrib><creatorcontrib>Wang, Hailong</creatorcontrib><creatorcontrib>Wong, Ming-Hung</creatorcontrib><title>Formation and distribution of methylmercury in sediments at a mariculture site: a mesocosm study</title><title>Journal of soils and sediments</title><addtitle>J Soils Sediments</addtitle><description>Purpose
