A renaissance for genotoxicity testing?
Article Abstract:
Genotoxicity assays are gaining interest that may result in a better idea of their practical use, as they have yet to be officially integrated into regulations controlling wastewater effluents, air emissions or contaminated soils. While these tests have long been used to measure the potential of environmental samples to induce mutations or other types of genetic damage, their use within a regulatory framework is inhibited, mainly by the difficulty of appraising the real risks for humans, from exposure to substances that appear to be genotoxic in bacterial or mammalian cell test systems. However, these tests may assume a greater role in future environmental policy, as certain ecotoxicologists focus on genotoxic effects in organisms and the related adverse effects for exposed populations.

Selenium removal using Ca-based sorbents: reaction kinetics
Article Abstract:
Intrinsic kinetics of the chemical reaction between calcium-based sorbents and selenium oxide is investigated by researchers at Ohio State University. In addition to basic kinetic parameters such as activation energy of the reaction and sorben initial surface area, the study also aimed to obtain initial reaction rate. The researchers found the rate of reaction to vary with the initial sorbent surface area. Sorption of selenium oxide in the presence of sulfur dioxide in the gas phase indicates that the two reactions are competitive. Selenium is one of the most volatile trac metallic emissions from utility boilers and coat-fired combustors.

Indoor air pollution and sick building syndrome. Monitoring aerosol protein as a measure of bioaerosols
Article Abstract:
The design and construction of an indoor air sampling device that measures aerosol protein concentration is presented. The basis of the air sampler's operation is in the detection of the suspended proteins, which is reacted with acidic Coomassie blue G, and detected at optical absorbance at 600 nm. A test of the equipment adequately measured suspended proteins in a kitchen as well as in a building with fungal contamination problems.
