  • Mercury

    Abstract Mercury is a naturally occurring metal found in the Earth’s crust. At high doses, mercury is known to cause adverse human health effects. Over the past several years, EPA (the Environmental Protection Agency) has focused on mercury exposures because of its potential to cause adverse human health and environmental effects, and because of its persistence and widespread distribution in the ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Mercury stabilization takes the sting out of mercury

    In elementary form, mercury is a danger to humans and the environment. But chemically bound to sulfur it loses its toxicity and can be disposed safely. The process which transforms the highly toxic metal into an unproblematic red powder is called mercury stabilization. As a specialist for cleaning mercury contaminated soil and waste by vacuum distillation econ also offers a process for mercury ...

  • Mercury Spill Control Procedures

    Mercury is a dangerous neurotoxin that can have damaging affects on both the central nervous system and renal system of humans. Exposure to mercury can cause serious developmental delays in children, and high level exposure is life threatening. When exposed to air, mercury vaporizes, readily becoming a dangerous aerosol that can be absorbed into the lungs and spread throughout the body. This is ...


  • Mercury Spill Control Procedures

    Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury"s hidden danger also lies in when at room temperature, when exposed it vaporizes readily. Once ...

  • Inorganic mercury accumulation in rice (Oryza sativa L.)

    To investigate the source and process of inorganic mercury (IHg) accumulation in rice, we monitored the concentrations of IHg in tissues of rice plants (Oryza sativa L.) from four experimental plantation plots. Biweekly during the rice‐growing season, tissues of rice plants, corresponding soil, precipitation, and irrigation water samples were collected. The sampling data support the following: ...

  • L.A. mercury spill provides opportunity for education

    The uncertainty surrounding a mercury spill on a Los Angeles subway platform this past December was reported by many leading news organizations, including coverage by the Los Angeles Times, CNN and Fox News, among others. Many of these news stories focused on the slow response to the incident and the potential for this to have been associated with terrorism. While these are valid concerns that ...

  • 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 ...

  • Determination of trace amounts of mercury (II) by catalytic kinetic method in environmental samples

    A highly selective and sensitive, spectrophotometric method is developed for the determination of Mercury(II) in environmental waters samples, based on indicator reaction of potassium hexacyanoferrate(II) and 2-methylpyrazine (2-Mepz), catalysed by Hg(II). The reaction was monitored spectrophotometrically at pH = 3.50 ± 0.02 and 25.0 ± 0.1°C by measuring the change in absorbance over time at 447 ...

  • New University of Minnesota study documents mercury vapor emission levels and need for safer packaging, storage and transportation of fluorescent lamps

    Results of a recent study conducted by the University of Minnesota School of Public Health, Division of Environmental Health Sciences suggest that most containers used for storage and transportation of used fluorescent lamps to recycling centers do not provide necessary levels of protection against mercury vapors emitted from broken lamps. The new study, published in the March issue of the ...

  • Cadmium regarded as the most serious contaminant of the modern age

    Abstract Cadmium is today regarded as the most serious contaminant of the modern age. It is absorbed by many plants and seacreatures and, because of its toxicity, presents a major problem for foodstuffs. Contamination through fertilisers becomes an increasing problem. Unlike lead, cadmium contamination cannot be removed from plants by washing them; it is distributed throughout the organism. It ...

    An analysis of the lighting industry shows a trend away from incandescent bulbs to fluorescent bulbs. Incandescent bulbs use more energy and are more costly and less effective than fluorescent bulbs in the amount of artificial light they produce, as fluorescents produce more lumens than incandescents. Using fluorescent bulbs, however, is not entirely without risk because they contain mercury, a ...


  • Sensitive quantification of trace zinc in water samples by adsorptive stripping voltammetry

    A simple and sensitive adsorptive stripping voltammetry method was developed for determination of Zn using N-nitrozo-N-phenylhydroxylamine (cupferron) as a selective complexing agent. This complex absorbed on the hanging mercury drop electrode and created a sensitive peak current. The peak current and concentration of zinc accorded with a linear relationship in the range of 0.85–320 ng ...
