"Holes" in Student Understanding: Addressing Prevalent Misconceptions Regarding Atmospheric Environmental Chemistry  Sara 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.

A Passive Sampler for Determination of Nitrogen Dioxide in Ambient Air  Dan Xiao, Lianzhi Lin, Hongyan Yuan, Martin M. F. Choi, and Winghong Chan
This article describes the use of a passive sampler for detecting and collecting nitrogen dioxide, NO2, in ambient air. This device is based on microporous PTFE membranes that allow air samples to diffuse through and subsequently react with an absorbing reagent solution. The absorbance value of this reagent is proportional to the NO2 concentration in ambient air. It has been successfully applied to determine the NO2 concentrations in various sampling sites.

Just Breathe: The Oxygen Content of Air   JCE Editorial Staff
Students estimate the percent oxygen (volume) in air using steel wool in a test tube that is inverted in a beaker of water. Oxygen in the trapped air reacts with iron to form rust, and the water level rises inside the test tube; within 30-45 minutes, the majority of oxygen is consumed.

Photocatalytic Degradation of a Gaseous Organic Pollutant  Jimmy C. Yu and Linda Y. L. Chan
A simple and effective method to demonstrate the phenomenon of photocatalytic degradation of a gaseous organic pollutant was developed. Titanium dioxide (anatase) was used as the photocatalyst, and sunlight was found to be an effective light source for the activation of TiO2. The organic pollutant degrade in this demonstration was a common indoor air pollutant, dichloromethane.
