  • How To Handle Chemical Spills & Cleanups

    FAST-ACT is designed for liquid and vapor chemical releases, but the chemicals it attacks does not need to be limited to what we traditionally think of as a chemical spill. Toxic and noxious chemicals can come from a variety of sources such as waste water, decomposition, household chemicals, and animals. Since FAST-ACT can be applied to liquid spill or vapor release enabling Emergency Responders ...

  • Health Hazards of Welding

    At present, it is estimated that more than one million workers are employed as welders worldwide (Sundin, 1998), with more than three million performing welding intermittently as part of their work duties (Sferlazza and Beckett, 1991). Manual metal arc welding (MMAW) and flux core arc welding (FCAW) are two commonly used procedures in the construction industry and in numerous other industrial ...

  • Welding fume hazards

    Welding is tough work.  Not many who begin as welders retire as welders.  Eventually practically every welder develops cataracts.  Neck and back problems are also a foregone conclusion. There is also a long list of possible health problems depending on the type of welding.  Recently, the Occupational Health and Safety Administration (OSHA) identified hexavalent chromium as a ...

  • Recovery Of Metals Using Combustion

    Process industries generate a number of hazardous waste streams containing metals bound with organic components. These metals can be quite valuable if they can be separated from the organic components and recovered. Four projects are discussed. ...

  • Management of Hazardous Wastes

    ' Management of hazardous waste is a growing concern in many countries. The long-term impacts and costs of improper disposal can be very high and the emphasis must be on prevention. A comprehensive management system should include (i) policies, institutions and effective regulations and (ii) adequate and acceptable disposal facilities (either public or private). This note outlines the key ...

  • The Hazards of Being in a Beauty Salon

    There are many health risks associated with the beauty industry due to the chemicals found in the products. We are all affected by these chemicals every time we go to the beauty salon. Many of the products found in these salons are classified as hazardous and extreme caution should be taken into consideration when using these products. They’re made for professional use only; therefore, ...

  • Heavy Metals in Vehicles II

    Untitled Document Executive Summary Directive 2000/53/EC on End-of-Life Vehicles aims at the prevention of wastes from vehicles and at the reuse, recycling ...

  • Assessing natural contents of hazardous metals in soils by different analytical methods and its impact on environmental legislative measures

    A variety of analytical techniques are commonly used to assess natural metal concentrations in soils. Although the choice of the analytical procedure may appear to be an unimportant issue, through an example from the Po Plain we document that for specific hazardous metals the arbitrary choice between separate analytical techniques may have contrasting legislative implications. Comparative ...

  • Use of earthworms (Eisenia fetida) and vermicompost in the processing and safe management of hazardous solid and liquid wastes with high metal contents

    Two feasibility studies using the earthworm (Eisenia fetida) and vermicompost in the processing and remediation of solid and liquid wastes with high metal content are presented: vermicompost as adsorbent substrate for remediation of wastewaters contaminated with metals; earthworms for remediation of arsenic (As) and mercury (Hg) in landfill soils. The feasibility of vermicompost for the ...

  • Shredding of highly flammable hazardous waste

    Satrind S.p.A. has a consolidated experience in engineering plants with nitrogen blanketing protection system for shredding of highly explosive hazardous waste in previously sealed into proper containers (such as metal or plastic drums, IBC tanks, etc.) and sludge material. During treatment of hazardous wastes, vapors or flammable gases are released with dangerous emissions which are highly ...

  • OECD workshop on the environmental assessment of metals

    I recently contributed to a workshop organised by the OECD which was aimed at raising awareness of the various approaches that have been developed (mostly in Europe and North America) for performing hazard assessments for metals. The workshop covered a broad variety of issues such as how to deal with the very large datasets that are available for some metals, ensuring that data are both reliable ...

  • Hazardous waste characterisation of high-density discharge lamps

    This study was conducted to assess the relative hazards of used high intensity discharge lamps, based on metal analysis. The paper indicates the inherent difficulties associated with the samples and describes how this particular type of waste might be analysed. The lamps were analysed for total and soluble metals, including mercury, in order to determine inorganic persistent and bio-accumulative ...

  • Salinity changes impact of hazardous chemicals in Enchytraeus albidus

    Supra‐littoral ecosystems are among the most challenging environments for soil organisms, particularly when facing salinity fluctuations frequently combined with the presence of contaminants as a result of intense anthropogenic activities. Knowledge of how salinity influences the effect of contaminants in supra‐littoral species is crucial for determining the safety factors required when ...

  • Hazardous Waste Incineration Slag Optimisation by Additives

     Abstract Rotary kiln incineration combined with the disposal of residual slag on landfills defined by German landfill regulations is the most acceptable treatment for hazardous waste with respect to the environment. The objective of research is to optimize the elution behavior of HWI-slag. Quality-improved slags may be disposed off on cheaper landfill sites still applying to the landfill ...


  • Hazardous Spill Cleanup Considerations for Non-Biohazards

    An article on chemical considerations related to the cleanup of non-biohazardous hazardous materials spills.  For examples,  Concentrated Solutions of Acids and Bases Spills of concentrated solutions of acids and bases must be neutralized first and then disposed of appropriately. Please note that concentrated solutions of acids and bases that contain other chemicals, such as ...

  • Hazardous waste cleans up its act

    Instead of landfill, incineration is being used increasingly in the UK to dispose of waste while recovering energy. The processes for controlling air pollution at these facilities creates a hazardous waste that represents approximately 3.5% of the original waste input by mass. Around 170,000 tonnes of Air Pollution Control (APC) residue, the hazardous by-product of incineration, is created every ...

  • Monitoring heavy metals for compliance with RoHS and WEEE directives

    The rapid expansion in the quantity of used electronic and electrical appliances has created a need to safely dispose of the used equipment. The European Community has introduced regulations to enforce limits on the amount of toxic metals and organic chemicals used in the production of material. Compliance with the regulations will help prevent hazards for future generations when the equipment is ...


  • Hazardous substances in Europe`s fresh and marine waters

    Chemical substances are an essential part of our daily lives. They are used in health and consumer products, in food production and in a growing range of environmental technologies, to name but a few examples. They can be natural substances, they can be formed as the unintended by-product of natural and human-induced processes, or they can be synthesised specifically for use in industrial ...
