  • What is the difference between a REL and a PEL?

    There is often confusion between exposure limits put out by different agencies even within the same administration. For example, here the National Institute for Occupational Safety and Health (NIOSH) establishes Recommended Exposure Limits (RELs) whereas the Occupational Safety and Health Administration (OSHA) issues Permissible Exposure Limits (PELs). Realizing the difference between the two is ...

  • Ruthenium-Catalyzed Synthesis of Dialkoxymethane Ethers Utilizing Carbon Dioxide and Molecular Hydrogen

    The synthesis of dimethoxymethane (DMM) by a multistep reaction of methanol with carbon dioxide and molecular hydrogen is reported. Using the molecular catalyst [Ru(triphos)(tmm)] in combination with the Lewis acid Al(OTf)3 resulted in a versatile catalytic system for the synthesis of various dialkoxymethane ethers. This new catalytic reaction provides the first synthetic example for the ...

  • Superplastic deformation of solid wood by slipping cells at sub–micrometer intercellular layers

    In order to facilitate the generation of a flow phenomenon due to the slipping of wood cells under a specific temperature condition, a phenol formaldehyde resin of low molecular weight was introduced into wood cells. The effects of the existence of phenol formaldehyde molecules in wood cells on the flow behaviour of solid wood were investigated experimentally by means of a free compression test. ...

  • Cavitational technology in wastewater treatment process

    Cavitation is one such recent technique which has been found to be substantially beneficial in wastewater treatment. Cavitation can be described as formation, growth and sub-sequent collapse of cavities releasing large magnitudes of energy locally, creating conditions similar to hot spots, and also generating strong oxidizing conditions by way of ...

  • Wastewater treatment from phenol by AVS-100

    Qualitative treatment of wastewater from phenol and other organic contaminants has a great practical importance within different branches of industry. In many cases, contemporary ways of usage by enterprises do not provide high qualitative treatment (degree of phenol decline is 75-90%). These ways have defects such as long process duration from 3 to 5 hours, long processing time, high reagent ...

  • Sampling of Carbonyls Using a Dual-Layer LpDNPH Glass Sampling Tube and HPLC Analysis

    The dual-layer LpDNPH sorbent tube is an air sampling device designed for sampling carbonyls (e.g. formaldehyde) in ambient, indoor, and industrial atmospheres. Carbonyls are trapped on our high-purity silica gel adsorbent coated with 2,4-dinitrophenylhydrazine (2,4-DNPH) where they are converted to stable hydrazone derivatives. The derivatives are eluted from the tube in acetonitrile and ...

  • Disinfection of tertiary wastewater effluent prior to river discharge using peracetic acid; treatment efficiency and results on by-products formed in full scale tests

    This is an investigation of chemical disinfection, with peracetic acid (PAA), in a tertiary sand filter at a full scale activated sludge plant with nitrification/denitrification and P-removal. The reduction efficiency of Escherichia coli and intestinal enterococci in the sand filter is reported. E. coli log reductions of between 0.4 and 2.2 were found with ...

  • Dangers of Formaldehyde used as adhesive in manufacture of wood-based panel products.

    Formaldehyde is a chemical widely used to manufacture building materials and various household products.  Wood based panels can emit small amounts of formaldehyde to the air and each panel type has a product standard governing the testing and certification of that product for formaldehyde emissions. Anyone involved in the manufacture of these products could be exposed to formaldehyde in ...

  • High concentrations of Aldehydes can be found in the hospital environment

    Both Formaldehyde and Glutaraldehyde are found in the hospital environment at higher concentrations than those to which the general population is exposed. Their possible adverse health effects are therefore very important to those working in certain parts of hospitals and to patients whose health status may be compromised. Both compounds are irritants and can cause sensitisation. Glutaraldehyde ...
