Traceability and reliable results are the two pillars of analytical methods; certified reference
materials (CRMs) meet this requirement. ISO 17034: 2016 credentials provide brief …

Mercury (Hg) contamination in aquatic systems is a universal concern because of its
persistence, bioaccumulation, toxicity, and trans-boundary nature. The current study focuses …

This study focuses on the distribution of some selected organochlorine pesticides and
emerging contaminants within the surface sediments of an Arctic fjord, Kongsfjorden and …

The bacterial reduction of mercury is one of the transformation processes where ionic form
(Hg 2+) converts into elemental form (Hg 0). The biological reduction of mercury is facilitated …

The contents of total mercury (THg) and methylmercury (MMHg) were measured in Nansi
Lake and its inflow river estuaries to investigate their spatial distribution characteristics and …

Mercury concentrations in the atmosphere, surface waters, and soils have increased beyond
natural levels as a result of human activities, which poses a risk to human and …

The following study measured dissolved organic carbon (DOC) and total mercury (THg)
concentrations in acid sensitive lakes in the Republic of Ireland. Sixty-eight upland lakes …
