the petrochemical industry is the most important and most widely active industries in the country. due to the variety and complexity of industrial products, it also produces a wild range of pollutants. mercury waste disposal from chlor-alkali units is one of the fundamental problems of this industry. various studies have shown that phytoremediation system for removal of mercury from aqueous sol...

background mercury is one of the most toxic heavy metals. even a small amount of it is toxic for all living organisms. some of bacteria have developed special resistance mechanisms against mercury, in addition to resistant to different antibiotics. these bacteria usually acquire hg and antibiotic resistance genes via horizontal gene transfer in their habitat. objectives the aim of this study wa...

objective mercury poisoning is one of the important recent causes of mortality and mortality in children worldwide, particularly in industrial environments; mercury is a poisonous metal, especially harmful to the nervous and immune systems and the kidneys and can even be fatal. elemental mercury is present in thermometers, barometer batteries, sphygmomanometers and latex paints. inorganic mercu...

mercury is a dangerous and an extremely toxic element, which can transfer to the food chain.presence of this element in the atmosphere particularly during the rainy seasons cause soil and environmental pollution, therefore this research will evaluate the transformation of mercury vapor from the atmosphere through precipitation into the soil. in the present study, mercury concentrations were det...

Mercury at low concentrations represents a major hazard to microorganisms. Inorganic mercury has been reported to produce harmful e€ects at 5 lg/l in a culture medium. Organomercury compounds can exert the same e€ect at concentrations 10 times lower than this. The organic forms of mercury are generally more toxic to aquatic organisms and birds than the inorganic forms. Aquatic plants are a€ecte...

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...

mercury mineralization has occurred in relation with a listwaenitic type hydrothermal alteration system in tavreh area located northwest of khoy. mercury-bearing alteration zone which has an area about 0.4 km2 is situated in one of aland river upstreams. the only mercury compound found in this district is mercury sulfide (cinnabar) deposited as vein and veinlet forms. geochemical investigations...

The potential reproductive toxicity of mercury vapour was investigated by comparing the rate of spontaneous abortions among the wives of 152 workers occupationally exposed to mercury vapour with the rate among the wives of 374 controls in the same plant. The results indicate an increase in the rate of spontaneous abortions with an increasing concentration of mercury in the fathers' urine before...

By applying our understanding of lunar space weathering processes, we can predict how space weathering will effect the soil properties on Mercury. In particular, the extreme temperature range on Mercury may result in latitudinal variations in the size distribution of npFe 0 , and therefore the spectral properties of the soil.
