  • Diurnal variations of total mercury (THg), reactive mercury (RHg), and dissolved gaseous mercury and water/air mercury flux in warm and cold season from fresh waters of Southwestern China

    Diurnal variations of water total mercury (THg), reactive mercury (RHg), and dissolved gaseous mercury (DGM) concentrations and mercury flux were monitored at two sites in warm and cold season in an alkaline reservoir in Southwestern China. Concentrations of THg and RHg as well as Hg fluxes usually exhibited a consistent diurnal trend with elevated values observed during day. The increasing ...

  • Estimation and Mapping of Wet and Dry Mercury Deposition Across Northeastern North America

    Whereas many ecosystem characteristics and processes influence mercury accumulation in higher trophic-level organisms, the mercury flux from the atmosphere to a lake and its watershed is a likely factor in potential risk to biota. Atmospheric deposition clearly affects mercury accumulation in soils and lake sediments. Thus, knowledge of spatial patterns in atmospheric deposition may provide ...

  • Combination filters

    Simply defined, a combination filter is one that does at least one other processing job at the same time as filtering a suspension. The classic example, of course, is the packed bed of activated charcoal, which acts as a remover of chemical impurities from the suspension, as well as removing dust particles - although this is actually not a very good example, because it is primarily an adsorber, ...

  • All Waste is not created equal

    If you live in a house, apartment or similar abode, you produce waste. Right? You probably can't go a week without producing waste. All kinds of waste. Call it trash if you want. It's still waste. And if you don't live where recycling is mandatory or there is no outlet for your voluntary environmental tendencies, everything goes into the trash - bottles, cans, cardboard, plastics, bottle caps, ...


  • Advanced WESP designs assure superior gas cleaning performance

    Nowadays, many industries are facing formidable environmental challenges and there is a growing need for effective, economical gas cleaning and air pollution control equipment. Michael Beltran of Beltran Technologies, Inc. reports on a renewed interest in high-efficiency wet electrostatic precipitators (WESPs) and discusses their importance for controlling sulphuric acid mists and other ...

  • Dust monitoring

    Generally, two different approaches are used to measure the amount of dust deposited on a surface; Determination of the soiling of a surface, by a change in its properties; Determination of the quantity of dust deposited, by weight. WHAT IS DUST? Dust is a generic term used to describe fine particles that are suspended in the atmosphere. Dust comes from a wide variety of sources, including soil, ...
