Environmental Issues

Ozone

? Chemistry of Ozone Depletion Sections include proposed reactions for the formation and distruction of ozone, halogen catalysis of ozone degredation, and the removal of chlorine from the atmosphere. Links to articles and technical papers about ozone depletion. Sites with pictures of the ozone hole are also present.

? EPA Ozone Depletion Homepage Effect of air conditioners on the ozone layer, list of ozone-depleting substances, list of substitutes for ozone depleting substances, glossary of common terms.

? Stratospheric Ozone Analysis Polar images of total ozone levels in northern and southern hemispheres. Archival images back to 1995.

? The Chemical Ozone Lists physical properties of ozone along with a discussion of its chemical properties and some specific reactions. Click on MOTM Bristol and scrool down to ozone.

Health Risks

? Dangers of Lead Still Linger An overview of the dangers of lead in the environment. Includes sections on lead ingestion, risk assessment, primary sources, lead in drinking water, lead in ceramicware, screening and treatment, etc.

? Long-Term Effects of Chronic Low-Dose Mercury Exposure Mercury is ubiquitous in the environment, and in our mouths in the form of "silver" amalgams. Once introduced to the body through food or vapor, mercury is rapidly absorbed and accumulates in several tissues, leading to increased oxidative damage, mitochondrial dysfunction, and cell death. This article gives an in-depth overview on the sources of mercury and the adverse effects on the body. There is a long list of (paper) references.

? Questions and Answers about Dioxins Structure, sources, chemical properties, and heath effects of Dioxin.

? Synthetic Auxins as Weed Killers Structures of the herbicides 2,4-dichlorophenoxy acetic acid (2,4-D) and 2,4,5-trichlorophenoxy acetic acid (2,4,5-T) that were used in a mixture better known as "agent orange" to defoliate the forest in parts of South Vietnam.
