  • On the Ground with Diesel Corrosion - Case Study

    When the EPA revealed the results of its study in July on the increasing presence of substantial corrosion in diesel fuel tanks, it proved that the problem is much larger than anyone anticipated. The facts are staggering: 83%of the diesel tank systems exhibited moderate-to-severe corrosion. 75%of the owner/operators of those diesel tanks had no idea it was ...

  • Thermal Desorption-GC/MS Analysis of polycyclic aromatic hydrocarbons on fine particulates in air

    Polycyclic aromatic hydrocarbons (PAHs) are commonly found throughout the environment in soil, water and adsorbed to fine particulate matter in air. Of the 16 common PAHs, 7 have been classified as animal carcinogens by the International Agency for Research on Cancer (IARC). Resulting from this classification, PAHs are monitored and regulated in the environment. Analysis of PAHs in soil and water ...

  • EPA Study: 83% of diesel tanks have moderate to severe levels of corrosion

    The EPA has released the results of the largest survey to-date on corrosion levels in underground storage tanks (USTs) containing diesel fuel -- and the results are staggering. The research showed that 83 percent of the USTs studied exhibit moderate to severe corrosion. Worse, only 25 percent of the owners of those tanks with corrosion were aware of it prior to the study. ...

This report presents results of the work undertaken on three different vehicles complying with the EURO4 ...


  • Low-mass PM analyzer MEXA-1370PM — Improvement of the Performance for PM Composition Analysis —

    Particulate matter (PM) emitted from engines is currently measured by the filter weight method. The filter weight method passes diluted emission gases through a filter collecting the PM, and post test weighs the mass of the collected PM on a precision balance. However, this method is time consuming, and with decreasing PM emission volumes, improvements in accuracy were needed. So the MEXA-1370PM ...
