In this string of updates about the projects I am working on I would like to present the latest; the Railyard Risk Assessment. This project focuses on a hazard, quantification of possible exposures, use of dose-response information to determine risk, and a summary that expands on uncertainties and tries to give an idea of what it all means. This, apparently, is risk assessment.
Thanks to Ben’s extracurricular work, we landed a nice project right here in Atlanta. We decided to look at residences being built right next to two large rail yards on Atlanta’s west side.
We modeled the emissions coming from the yard’s activities (using a Cali yard as a proxy) and then used a model from EPA to obtain the resultant concentrations of diesel particulate matter at the new homes. The actual risk is still being determined but the results could prove to be very interesting. Below is a movie shot from one of the lots.

This is one example of how marketing and narrowly focused, under-developed certifications are capitalizing on ‘green‘ (also read healthy) trends without necessarily furthering the whole objective.
