Top-down analysis of virtual atmospheric mercury emission networks can direct efficient demand-side policy making on mercury reductions. Taking China-the world's top atmospheric mercury emitter-as a case, we identify key contributors to China's atmospheric mercury emissions from both the producer and the consumer perspectives. China totally discharged 794.9 tonnes of atmospheric mercury emissio...

The aim of this study was to examine the experimental uptake of mercury and the enzymatic response, i.e., glutathione S-transferase (GST) activity, to this metal introduced into the medium under organic (methylmercury chloride) and nonorganic (mercury chloride) forms. Shoots of Posidonia oceanica were collected in a nonpolluted area in the northwestern Mediterranean Sea and were treated in aqua...

In this study, we present the response of model results to different scientific treatments in an effort to quantify the uncertainties caused by the incomplete understanding of mercury science and by model assumptions in atmospheric mercury models. Two sets of sensitivity simulations were performed to assess the uncertainties using modified versions of CMAQ-Hg in a 36-km Continental United State...

OBJECTIVE To describe demographic characteristics, patterns of use, reported symptoms, and laboratory results associated with mercury exposure among people who used a beauty cream containing mercury. DESIGN. Descriptive study of a case series. SETTING The Hong Kong community. PARTICIPANTS Users of a cream cosmetic who contacted the Department of Health following a public announcement. MAI...

AIM To compare the total and organic mercury content in sea-fish samples from Croatia, where fishing occurs in a closed part of the Mediterranean Sea, and from other countries fishing mostly in the oceans. METHOD During 1997, we collected at the Zagreb fish market a total of 115 samples of fifteen kinds of fish including bathypelagic, pelagic and elasmobranch fish, caught in the wider coastal...

In 2009, we conducted a survey to assess the use of mercury-based thermometers and sphygmomanometers and their disposal in Croatian healthcare facilities. The questionnaire addressing the use of mercury-based medical devices, waste management, preferences between mercury-based and electronic devices, and the knowledge on mercury toxicity was filled by ward nurses affiliated with 40 (71.4 %) out...

BACKGROUND High levels of mercury in the Cree population of James Bay, Que., have been a cause of concern for several years. This study examines changes in mercury levels within the Cree population between 1988 and 1993/94 and identifies potential determinants of high mercury levels. METHODS Data on mercury levels among the Cree were obtained through a surveillance program undertaken by the C...

We estimated daily mercury intakes from seafood in 154 mothers residing in several cities and towns in Akita, Japan, to address the relationships between the reference dose (RfD of 0.1 microg/kg body weight per day, derived by US EPA) and daily mercury intakes, combined with hair mercury levels. The frequency and volume of seafood ingested by them were examined using a food frequency questionna...

  ABSTRACT Background and Objective: There have been concerns over possible association between mercury and neurodevelopmental outcomes in infants. In this study we aimed to determine whether blood levels of mercury are above safe values in Iranian infants or not. Materials and Methods:  A total of 85 infants (0, 2, 4 and 6 months old) were enrolled in this study. All of them received vaccin...
