Anthropogenic sources of chlorine and ozone formation in urban atmospheres

Article Abstract:

In August 1993, an alkane-rich hydrocarbon plume passed over (Cl)(sub 2) from man-made sources, followed within two hours by a loss of alkanes and a large rise in ozone concentration. The results from subsequent environmental chamber experiments indicate that (Cl)(sub 2) enhances (O)(sub 3) production, with peak (O)(sub 3) concentration (((O(sub 3))(sub peak))) rising by up to a factor of 6 when (Cl)(sub 2) is added. The time needed to reach 0.63(((O)(sub 3))(sub peak))) was lowered by up to a factor of 3.5.

The effects of altitude on heavy-duty diesel truck on-road emissions

Article Abstract:

In this study, the effects of altitude on heavy-duty diesel truck on-road emissions were examined, which were taken from five locations in the U.S. and Europe. The study is broken down into an introduction, a discussion of the experiment and a discussion of its results. Various tables and graphs accompany the article.
