“…Many analysis methods for Hg and MeHg exist [19], and different studies use different qualitycontrol protocols. Among the reviewed articles, the method used most often was cold vapor atomic fluorescence spectroscopy (CVAFS); a few used atomic absorption spectroscopy (AAS).…”

Abstract-Mercury is a global pollutant that can be transported over long distances and can bioaccumulate. Currently, China is the country that contributes most to atmospheric Hg emissions and has the greatest intentional (industrial) use of Hg. Mercury in the Chinese environment is generally elevated, particularly in air and water bodies. Remote areas in China also show elevated Hg levels in air and water bodies compared to other rural regions in the world. Large river estuaries are often heavily affected by upstream industrial sources.

“…In fact, Hg occurs as different chemical species, including inorganic (e.g., Hg(I) or Hg(II)) and organic (e.g., methyl mercury (MeHg), ethyl mercury (EtHg), and phenyl mercury (PhHg)). It has been proved that mercury with different forms exhibited quite different toxicities, but organic Hg compounds are more toxic than inorganic species (Leopold et al, 2010). Among them, MeHg is the most common but most toxic mercurial species in the environment (Mason and Fitzgerald, 1996).…”

Mercury (Hg) exists in different chemical forms presenting varied toxic potentials. It is necessary to explore an ecological risk assessment method for different mercury species in aquatic environment. The predicted no-effect concentrations (PNECs) for Hg(II) and methyl mercury (MeHg) in the aqueous phase, calculated using the species sensitivity distribution method and the assessment factor method, were 0.39 and 6.5 × 10 −3 μg/L, respectively. The partition theory of Hg between sediment and aqueous phases was considered, along with PNECs for the aqueous phase to conduct an ecological risk assessment for Hg in the sediment phase. Two case studies, one in China and one in the Western Black Sea, were conducted using these PNECs. The toxicity of mercury is heavily dependent on their forms, and their potential ecological risk should be respectively evaluated on the basis of mercury species.

“…The development of new methods for the quantification of mercury at ultra-trace levels is a challenging task and one of considerable interests. Traditional methods such as atomic absorption spectrometry (AAS) and inductively coupled plasma mass spectrometry (ICP-MS) to detect mercury ions are often costly, timeconsuming and not appropriate for point-of-use applications [4], so there is a strong demand to develop a novel method with the advantages of the few interference, facile fabrication process, and low cost. The advantages of fluorescence signaling in its intrinsic sensitivity have encouraged the development of a variety of fluorescent sensors for the detection of metal ions [5][6][7].…”
