A Phase II Environmental Site Assessment (Phase II ESA) is an investigation of soil, groundwater, surface water, sediments, and occasionally bedrock or indoor air. The purpose of a Phase II ESA is to evaluate potential source areas of contamination, determine the extent of potential contaminant migration from the source areas, and determine if sensitive receptors are impacted. Campbell ...

The Cryo-EM Single Particle Analysis technique involves preparing numerous molecular samples with identical structures. These are dispersed and vitrified for random projection imaging, followed by computational angle determination and the alignment of particles with matching angles to emphasize distinctive, interpretable features. Assuming uniformity in molecular structure, the technique involves ...

by:Airzone One Ltd. based inMississauga, ONTARIO (CANADA)
Although air quality issues typically result from direct emissions from exhaust stacks or chemicals used in industrial processes, vapour intrusion is caused by contaminants in soil or ground water volatilizing (evaporating) and moving indoors through the foundation or floor slab. Vapour intrusion, particularly of volatile organic compounds (VOCs), is increasingly recognized as a potential source ...
