Knut Breivik and colleagues have developed a method to estimate the potential risks of organic chemical emissions emanating from commercial activities. No methods currently exist to quantitatively estimate the risks associated with such emissions and here the authors have sought to address this by developing an approach that looks at the quantities of organic chemicals used, their intended function and physical–chemical properties to estimate emissions to air, soil and water:
Screening organic chemicals in commerce for emissions in the context of environmental and human exposure

Matthew Nonnenmann et al have sought to overcome some of the limitations associated with culture-based techniques for identifying and quantifying fungi in environmental samples by using pyrosequencing. Pyrosequencing offers the potential for discovering new fungal species, where are more traditional methods such as PCR and QPCR require known species to develop assays. The paper compares the two approaches in dust samples, where fungi may be associated with lung disease:
