Organic and total mercury determination in sediments by cold vapor atomic absorption spectrometry: methodology validation and uncertainty measurements

Química Nova, 2012
The purpose of the present study was to validate a method for organic Hg determination in sediment. The procedure for organic Hg was adapted from literature, where the organomercurial compounds were extracted with dichloromethane in acid medium and ...

Methylation of mercury in earthworms and the effect of mercury on the associated bacterial communities. [PDF]

PLoS ONE, 2013
Methylmercury compounds are very toxic for most organisms. Here, we investigated the potential of earthworms to methylate inorganic-Hg. We hypothesized that the anaerobic and nutrient-rich conditions in the digestive tracts of earthworm's promote the ...

Reproductive-Toxicity-Related Endpoints in C. elegans Are Consistent with Reduced Concern for Dimethylarsinic Acid Exposure Relative to Inorganic Arsenic

Journal of Developmental Biology, 2023
Exposures to arsenic and mercury are known to pose significant threats to human health; however, the effects specific to organic vs. inorganic forms are not fully understood. Caenorhabditis elegans’ (C.

Metals and Breast Cancer: Risk Factors or Healing Agents?

Journal of Toxicology, 2011
Metals and metal compounds are part of our environment. Several metals are essential for physiological functions (e.g., zinc or magnesium); while the beneficial effects of others are uncertain (e.g., manganese), some metals are proven to be toxic (e.g ...

MERCURY IN FISHERY PRODUCTS FROM CENTRAL ADRIATIC SEA (OFFICIAL CONTROLS FROM 1995 TO 2009)

Italian Journal of Food Safety, 2011
Thanks to its properties, methylmercury is the most bioavailable form of mercury compounds. In fact, it causes the most toxic effects on the immune, cardiovascular, renal and central nervous systems, in particular the fetal brain.

Effect of peat and thiol-modified peat application on mercury (im)mobilization in mercury-polluted paddy soil

Ecotoxicology and Environmental Safety, 2023
Mercury (Hg) pollution in paddy soil has gained special attention because methylmercury (MeHg) can accumulate in rice grains. Therefore, there is an urgent need to explore the remediation materials of mercury-polluted paddy soil.
