On the outside front cover of JEM Issue 3 is a HOT article from William Cullen et al. reporting on the arsenic speciation in freshwater snails from Pender Island and Vancouver Island in Canada. Little is currently known about arsenic speciation and its life cycle variation in freshwater snails, which are an important food source for many creatures including fish and birds, and are occasionally consumed by humans.

On the inside front cover is a HOT article from Alexandra Steffen and colleagues from Environment Canada and the National Atmospheric Deposition Program (NADP) at the University of Illinois, reporting on a comparison of their data quality control protocols for the measurement of atmospheric mercury species. The protocols RDMQ™ and AMQC were developed independently by Environment Canada and the NADP respectively, and have been assessed by the criteria on which the data is quality controlled and comparability of the final data products.
