Abstract:
From triclosan to dioxins: How your handsoap leads to an unanticipated environmental problem. Triclosan is an antimicrobial chemical added to liquid handsoaps. After being washed down the drain, triclosan enters wastewater treatment plants where it is not completely removed. The triclosan (and related compounds) that is discharged into surface waters is transformed by sunlight into dioxins. Dioxins are persistent, bioaccumulative, toxic pollutants. Analysis of lake sediments demonstrates that dioxins arising from triclosan are accumulating in the environment.

Analytical Seminars - 2011.pdf
Seminars are another mechanism to expand your knowledge about modern analytical methods. The Department of Chemistry offers such seminars on a regular basis (see http://www.chem.umn.edu/seminar/).
Attendance to seminars is not required to do well in the course. Those interested in expanding her/his knowledge are welcome to attend.
Bonus points will be given for attendance to seminars demonstrated by posting a comment in the respective seminar entry in the blog. Posting on two seminars will be equivalent to one quiz. (Keep in mind that only the 10 highest quiz grades will be part of your final grade)
Post your comment in the entry corresponding to the seminar that you attended. Answer only one of the questions 1-6 below and the question marked with "*".
What was the main topic of the seminar?
1. What analytical technique(s) was (were) used? How does (do) the technique(s) work?
2. What are the samples? Analytes? Matrix interferences?
3. What figures of merit or criteria were used in these studies or reported in the seminar?
4. What are the conclusions drawn by the presenter?
5. What questions do you have that were not answered?
6. What parts were not clear in the presentation?
* How will you use a technique included in the seminar to investigate your analytical problem? What is this technique?
