Compliance with new environmental regulations for coal-fired boilers and other industrial sources has become a multi-pollutant effort in which minimizing costs is important. For example, the cost of mercury control chemicals is the largest cost associated with achieving mercury compliance under Mercury and Air Toxics Standards (MATS). Reducing the costs associated with maintaining emissions lim...

BACKGROUND Dendropanax morbifera Léveille has been employed for the treatment of infectious diseases using folk medicine. In this study, we evaluated the antioxidant effects of a leaf extract of Dendropanax morbifera Léveille in the hippocampus of mercury-exposed rats. METHODS Seven-week-old Sprague-Dawley rats received a daily intraperitoneal injection of 5 μg/kg dimethylmercury and/or oral ...

The Thief Process is a cost-effective variation to activated carbon injection (ACI) for removal of mercury from flue gas. In this scheme, partially combusted coal from the furnace of a pulverized coal power generation plant is extracted by a lance and then re-injected into the ductwork downstream of the air preheater. Recent results on a 500-lb/h pilot-scale combustion facility show similar rem...

Introduction Mercury poisoning has been recognized for over a century. Evans' (1962) report of poisoning due to chronic exposure to mercury vapour in industry is well known. Polson and Tattersall (1969) have described other circumstances including the ingestion of mercurous and mercuric chlorides, the subcutaneous, intravenous and intra-arterial injection of elemental mercury and acute exposure...

Exposure to heavy metals may have toxic effects on several human organs causing morbidity and mortality. Metals trigger or exacerbate autoimmunity in humans. Inbred mouse strains with certain H-2 haplotypes are susceptible xenobiotic-induced autoimmunity; their immune response such as mercury, gold, silver been explored. Serum antinuclear antibodies (ANA), polyclonal B-cell activation, hypergam...

Turbulent convection is often present in liquids with a kinematic viscosity much smaller than the diffusivity of the temperature. Here we reveal why these convection flows obey a much stronger level of fluid turbulence than those in which kinematic viscosity and thermal diffusivity are the same; i.e., the Prandtl number Pr is unity. We compare turbulent convection in air at Pr=0.7 and in liquid...
