I was flying back from a conference near Hartford a couple of weeks ago and realized that I had become a victim to compounding conservatism. How is compounding conservatism in risk assessment related to air travel? Well, let me tell you a story.
Chemistry Matters Inc. in conjunction with Statvis Analytics Inc. just hosted an invitation only event for select clients at Rodney's Oyster Bar this past week. The informal venue allowed great conversation along with the enjoyment of fish, seafood and raw oysters all while providing some informative science and...
One of the more common chemical groups that we work on is polycyclic aromatic hydrocarbons (PAHs). I have worked on them since 2002 when I developed methods to measure human exposure to PAHs at the Centers for Disease Control and have been working on them ever since. Since 2004, the projects involved PAHs and...
Happy New Year and welcome to 2018! I am back after a stay at home and cold (really cold, even for Canadian standards) holiday break. I was able to get some nice time with the family and even got some ski days in. It was quiet on the family front but we were busy on the business and company front.
River PAHs Characterization Part 3: 2017 – Red Deer Lakes, Sulfur Springs and an abandoned coal mine
This is the third in a series of blogs on river PAHs (Blog 1 and Blog 2 on River PAHs are here). The aim of our investigations is to answer the question “where did the PAHs come from that were present in all of the Alberta and Saskatchewan rivers?”
In the first post of this series on River PAHs characterization, I described the background to why Court and I have spent many hours driving across Alberta from border to border to collect sediment samples from the rivers of southern Alberta.
For the last few years we have spent a lot of our free time collecting sediment samples from rivers across southern Alberta and characterizing these for Polycyclic Aromatic Hydrocarbons (PAHs). Often driving many hours across prairie gravel roads for a single good sample, it quickly became a passion of quality...
In the first post of this series, I described the basis for how we became involved in determining a method for the detection of a natural, biogenic source of toluene. In this post, I describe how the process works and provide some thoughts on how to conduct an investigation.
You have had a spill… don’t panic, everything will be fine. Accidents happen. It is what you do next that is important. I have worked on many spills and here are what I believe are four of the most important things from a chemist’s perspective.
