Environmental concerns linked to railroad creosote

Article Abstract:

According to a study of the Swiss Federal Laboratories for Materials Testing and Research, one-third of the creosote applied to wooden railroad ties as a preservative is emitteed during normal service time. The study found that annual emissions from the Swiss railroad system totaled 1700 metric tons of creosote, including 140 t of the 16 polycyclic aromatic hydrocarbons that the U.S. Environmental Protection Agency has designated as priority air pollutants.

1H NMR application for characterizing water-soluble organic compounds in urban atmospheric particles

Article Abstract:

In the first study to use 1H NMR analysis of atmospheric particles, samples of atmospheric particles are taken from on top of an office building in Kobe City, Japan, near a freeway, and analysed for content. Graphs show the distribution of particles according to diameter and chemical makeup, and are compared to the content of diesel exhaust from a motor vehicle.

The leaching behavior of cement stabilized air pollution control residues: a comparison of field and laboratory investigations

Article Abstract:

Air pollution control residues trapped in cement are exposed to water-leaching tests in a landfill and the laboratory in order to evaluate the long-term effects of cement stabilization of pollutants. Leached elements are graphed, with a noted difficulty explaining the leaching behavior of heavy metals.
