chemical pollutants presence in water may induce severe ecological consequences and consequently affecting aquatic ecosystems integrity. heavy metals are dangerous pollutants for aquatic inhabitants that have a great stability. heavy metals contamination (pollution) of the surface waters happens widely by discharge of mill effluents. the objective of the present study was to determine the 50% l...

Mercury is a ubiquitous environmental toxicant that causes a wide range of adverse health effects in humans. Three forms of mercury exist: elemental, inorganic and organic. Each of them has its own profile of toxicity. The aim of the present study was to determine the effect of thimerosal, a topical antiseptic and preservative in vaccines routinely given to children, methyl mercury, and mercuri...

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...

With the advent of modern ophthalmic treatment the use of mercury preparations in ophthalmology has almost been relegated to past history, but mercurous chloride (calomel) is still occasionally used as an insufflation into the eyes, especially in such conditions as phlyctenular keratoconjunctivitis. Recently we saw a case wherein mercuric chloride (HgCl2) was mistaken for calomel and dusted int...

In vitro microbial contaminations are the most serious problems in plant tissue culture. Initial attempts for micropropagation of Dionysia tapetodes, a beautiful alpine cushion plant from north-east Iran, led to 100% explants contamination. Hence, the present study was conducted to develop an efficient surface sterilization protocol for in vitro culture of field collected D. tapetodes using com...

A large volume of waste mercury chloride catalyst (HgCl2) is generated by calcium carbide-based polyvinyl chloride production in China, which accounts for 30% of global mercury consumption. However, there are few studies on the leaching behavior and risk control of waste catalyst where mercury is in the form of HgCl2, which is more soluble than metal mercury and poses great threat to human heal...


 Bacillus cereus (IHB B 379) has been isolated from the sediments of illegal gold mining area located in Danau Biru Singkawang, these bacteria have resistant properties by being able to grow on media containing HgCl2 with a concentration 500 ppm. This study aimed determine effect temperature and mercuric chloride (HgCl2) growth optimum 379). The used Completely Randomized Factorial Design...

Administration of mercuric chloride (HgCl2; 5.0 mg/kg body weight) to male Swiss albino-mice resulted in significantly higher levels of testicular acid phosphatase (ACP) and alkaline phosphatase (ALP) activities as compared to control. In combination group where S. fusiformis (800 mg/kg body weight) was given before and after HgCl2 treatment, the mercury induced toxicity reduced in terms of dec...

In vivo and in vitro exposures were used to investigate the genotoxicity of mercuric chloride (HgCl2) to the marine snail, Planaxis sulcatus. The comet assay protocol was validated on gill cells exposed in vitro to hydrogen peroxide (H2O2, 0-50 μM). Snails were exposed in vivo for 96 h to HgCl2 (10, 20, 50, and 100 μg/l). Our results showed significant concentration-dependent increase in the ta...

Mercury (Hg) exposure is known to damage vital components of the central nervous system primarily through oxidative stress. Although Phyllanthus amarus (PA) reported be rich in antioxidants, there a dearth relevant research evidence show its protective activity against Mercuric chloride (HgCl2)-induced neurotoxicity. Accordingly, this study was designed investigate possible aqueous leaf extract...
