Mercury Removal using Anotec
Mercury removal from industrial settings can be a complex process because of the risks associated with handling mercury and the potential for mercury to be released into the environment. Mercury is a toxic substance that can harm humans and the environment, and it can be difficult to control because it can exist in various forms, including vapors, liquids, and solids. Anotec Hg Suppressor sprays ...

Regulating Mercury Emissions
Historically, mercury (Hg) has found its use in many products such as thermometers, batteries, and fluorescent lamps. However, mercury is extremely toxic, and it has in modern days been banned from use in most applications.By example, the Minamata Convention on Mercury from 2013 has been designed to prevent releases of mercury and mercury compounds in order to protect human health and the ...

Fluorescent lamps recycling - Case Study
The fluorescent lamps recycling plant was designed for a Taiwanese recycling company. The task was to develop a treatment plant which achieves a high recycling quota while keeping the investment level moderately low. This was achieved by combining several specially developed technologies. These technologies include a high efficient shredder-sieving system, the closed-loop washing unit, an ...

EPA: Mercury merits attention
The U.S. Environmental Protection Agency (EPA) continues to implement reporting requirements pertinent to the supply, use and trade of mercury in the United States. This column provides more information and a closer look into the EPA’s October 2017 proposed rule. The 2016 amendments to the Toxic Substances Control Act (TSCA) call for the EPA to establish periodic mercury reporting ...

Lumex Instruments takes part in making Mercury history
Minamata disease is one of the most notorious ecological catastrophes of the 20th century. Discharge of mercury-containing effluent by the "Chisso" chemical plant to the Minamata Bay in Kumamoto Prefecture, Japan, gave rise to a dangerous syndrome that seriously affects the central nervous system due to the toxicity of methylmercury, which gets into the body with contaminated food. In our blog, ...

Incandescent, Fluorescent, and Mercury
In light of many countries legislating the retirement of Thomas Edison’s beloved incandescent lamps in favor of more energy efficient compact fluorescent lamps, it is important to reassure the consumer that this phase-out is both necessary and safe. In order to properly illuminate the concerns regarding compact fluorescent lamps one must first understand their predecessor the incandescent ...

Are Universal Wastes DOT Regulated?
The answer is yes, no, and maybe. Under the DOT regulations, hazardous wastes are regulated in all modes (ground, air, rail, vessel) of transportation. EPA has classified specific hazardous waste as Universal Waste to streamline the process and encourage recycling of these materials (see 40 CFR 273). EPA has specifically addressed the DOT requirements for these waste at 40 CFR 273.52 as ...

What specification thermometers are available, and what are the differences?
Thermometers are used in most laboratories across all industries, and a wide range are available to suit any temperature monitoring task. For high accuracy applications that need to adhere to international standards, traditional glass specification thermometers are still the most popular choice. Specification thermometers are those which are manufactured to conform to internationally recognized ...

Mercury – The Facts, Myths and Clean Up Tips!
Mercury, the facts. Mercury is an element (Hg on the periodic table) found naturally in the environment. Mercury emissions can come from both natural and man-made sources. It is commonly used in mercury arc lamps for UV curing, however this is a very minimal amount (as little as 5mg) and is used in the lamp to increase the voltage. Due to the harmful effects of Mercury, many ‘Mercury ...

Toxins Found in E-Waste
One of the worst effects of a skyrocketing, global e-waste crisis is the risk of toxic contamination for the environment and communities. In fact, delving into the many chemical and heavy metal materials that make up most electronic devices, it seems that toxins and electronics go hand in hand. Though many manufacturers of electronic devices are finding innovative ways to work around toxins found ...

Continuous measurement of mercury emissions in combustion plants (Overview and new measuring method)
Introduction Continuous measuring devices have been used for continuous recording of Hg emissions in waste incineration plants since the early Nineties. Operators of combustion plants must maintain a 24-hour measured value of 30 μg/m³ mercury and a half-hourly average value of 50 μg/m³ in accordance with the 13th and 17th BImschV. In order to meet these requirements, measuring ...

The polychaete worm Nereis diversicolor increases mercury lability and methylation in intertidal mudflats
The polychaete worm Nereis diversicolor engineers its environment by creating oxygenated burrows in anoxic intertidal sediments. We carried out a laboratory microcosm experiment to test the impact of polychaete burrowing and feeding activity on the lability and methylation of mercury in sediments from the Bay of Fundy, Canada. The concentration of labile inorganic mercury and methylmercury in ...

The application of Flow Injection Technology to automating cold vapor MERCURY analyses
This document describes the application of flow injection technology to cold vapor mercury analyses. It can be obtained from PerkinElmer by requesting method number ENVA-100. Appendices 1 and 2 show letters from the US EPA indicating acceptability through the Alternate Test Program for both drinking water and wastewater sample analysis. 1.0 Scope and Application 1.1 This method measures total ...

Is there mercury in your industrial wastewater discharge?
An assessment of sampling locations for three industrial wastewater effluent piping systems is presented. The assessments provided demonstrate that by installing sampling ports at the appropriate location along an effluent stream’s piping system, truly representative samples can be collected. These real and accurate results scientifically prove that a specific industrial wastewater ...

Mercurycontamination detection in industrial premises
Summary Environmental pressures and subsequent legislation to control hazardous substances have seen a sharp decline in the use of mercury, although it remains an important chemical in many industrial processes and a wide range of products. This ongoing use and historic prevalence means that mercury contamination represents a significant hazard during decommissioning, demolition, repurposing or ...

Mercury Contamination in Turtles and Implications for Human Health
Mercury contamination threatens many ecosystems worldwide. Methylmercury bioaccumlates at each trophic level, and biomagnifies within individuals over time. Long-lived turtles often occupy high trophic positions and are likely to accumulate mercury in contaminated habitats. Millions of turtles worldwide are sold in Asia for human consumption, and consumers may be at risk if turtles contain high ...

Sulphate reducing bacteria to precipitate mercury after electrokinetic soil remediation
Combined treatment with electroremediation and sulphate reducing bacteria (SRB) was tested in laboratory and pilot scale. The contaminated soil came from a chlor-alkali factory and contained about 100 mg/kg Hg. Iodide/iodine complexing agent was used to mobilize mercury. Mercury iodide complexes were moved to the anode solution using an electric field. The anode solution was then mixed with ...

The source and risks of mercury in the offshore industry
Oil in Gas and RocksAlmost all oil and gas is found within the tiny spaces in sedimentary rocks, mainly sandstone and coarse-grained limestone. Bedrock limestone and sandstone, even though hard, also contain lots of pores that can contain water or oil or gas and other elements. Along with the gas and oil is a mixture of sand, silt & mud. This sludgy silt mud is rich in heavier metal elements ...
