Spatial patterns in mercury cycling and bioaccumulation at the landscape level in the Everglades were investigated by collecting and analyzing multimedia samples for mercury species and biogeochemical characteristics from 228 randomly located stations. Higher total mercury (THg) in environmental compartments (surface water, soil, flocculent detrital material (floc), and periphyton) generally oc...

Increased cardiovascular risk after mercury exposure has been described, but the underlying mechanisms are not well explored. We analyzed the effects of chronic exposure to low mercury concentrations on endothelium-dependent responses in aorta and mesenteric resistance arteries (MRA). Wistar rats were treated with mercury chloride (1st dose 4.6 microg/kg, subsequent dose 0.07 microg.kg(-1).day(...

land treatment method of municipal and industrial wastewaters for utilization of nutrients in the wastes for raising useful crops and tertiary(or advanced) treatment of the water for improving stream quality or to recharge falling water tables is increasing in some parts of the world, particulary in the arid area. as emphasis in this type of treatment method and prevention of surface and underg...

Organic matter isolated from the Florida Everglades caused a dramatic increase in mercury release (up to 35 μM total dissolved mercury) from cinnabar (HgS), a solid with limited solubility. Hydrophobic (a mixture of both humic and fulvic) acids dissolved more mercury than hydrophilic acids and other nonacid fractions of dissolved organic matter (DOM). Cinnabar dissolution by isolated organic ma...

A hypersaline protected wetland in the UAE was assessed from February to April of 2021 for parameters such as temperature, pH, COD, total dissolved solids, ORP, electrical conductivity, and E. coli, salinity, turbidity, chloride, ammonia, nitrate, nitrogen, phosphorus, heavy metals assess its current status. Wasit Nature Reserve’s salinity values ranged between 17.1 64.78 psu, while D.O 6.3 8.4...

This study was designed to investigate the effect of inorganic mercury (mercuric chloride) on biochemical, hematological parameters, and examining the histological changes in liver, and kidney tissues in male albino mice as a laboratory animal Model. The animals used for the sub-chronic study for mercuric chloride received 1/100 , 1/50, 1/20 and 1/10 of the calculated LD50 which were equivalent...

The reaction of 1, 2-bis(diphenylphosphino)ethane monoxide, a hybrid ligand containing both soft (P) and hard (O) Lewis base centers in the same molecule, with organotin(IV) chloride and mercury(II) chloride has been carried out using dichloromethane as solvent. The products [HgCl2.(dppeO).R2SnCl2]n [R = Me (1), Ph (2) and CH2Ph (3)] have been obtained in excellent yields and are characterized ...

Seven Japanese female workers exposed to mercury vapour at a concentration of < 0.02 mg Hg/m3 (8 h/day, 44 h/week) were examined for inorganic (I-Hg) and organic (O-Hg) mercury concentrations in urine, blood, and hair after 0, 4, 8, 17, and 23 months of exposure. Both I-Hg and O-Hg concentrations in urine and hair did not increase significantly even after 23 months of exposure. The concentratio...
