Special_Topics : AirPollutants (20 Variations)
Which of the following air pollutants can be described as a photochemically active free radical that contributes to acid rain and respiratory irritation?
Special_Topics : RainFallpH (20 Variations) The rainfall in central Wisconsin has a pH of 4.8 (National Atmospheric Deposition Program). Take a look at the EPA webpage Effects of Acid Rain: Lakes & Streams. This site has a chart of the pH at which several aquatic species begin to suffer. Determine which of the following species will be most affected by rainfall of this acidity if the lakes and streams in central Wisconsin aren't buffered enough to neutralize some of the acid. (There may be more than one correct answer.)
A Simplified Model To Predict the Effect of Increasing Atmospheric CO2 on Carbonate Chemistry in the OceanBrian J. Bozlee, Maria Janebo, and Ginger Jahn The chemistry of dissolved inorganic carbon in seawater is reviewed and used to predict the potential effect of rising levels of carbon dioxide in the atmosphere. It is found that calcium carbonate may become unsaturated in cold surface seawater by the year 2100, resulting in the destruction of calcifying organisms such as coral. Bozlee, Brian J.; Janebo, Maria; Jahn, Ginger. J. Chem. Educ.2008, 85, 213.

Experimental Determination of Ultraviolet Radiation Protection of Common MaterialsSusana C. A. Tavares, Joaquim C. G. Esteves de Silva, and João Paiva The oxidation of iodide is used as an indicator for the degree of exposure to UV radiation and to investigate the protection given by a simulation of ozone using plexiglass plates, sunscreen lotions, cotton cloth with different colors, and aqueous solutions with different concentrations of natural organic matter.

"Holes" in Student Understanding: Addressing Prevalent Misconceptions Regarding Atmospheric Environmental ChemistrySara C. Kerr and Kenneth A. Walz This study evaluated the misconception that global warming is caused by holes in the ozone layer, other ideas surrounding atmospheric chemistry that are responsible for the entanglement of the greenhouse effect and ozone depletion in students' conceptual frameworks, and the effectiveness of computer-based online data-analysis exercises to address these shortcomings. Kerr, Sara C.; Walz, Kenneth A. J. Chem. Educ.2007, 84, 1693.
