http://pontotriplo.org/triplepoint A selection of posts from Ponto Triplo - a Portuguese blog with links to the best chemistry sites, news and events Sun, 19 Apr 2009 23:15:30 +0000 en hourly 1 http://wordpress.org/?v=3.3.1 http://pontotriplo.org/triplepoint/2005/06/green_chemistry.html http://pontotriplo.org/triplepoint/2005/06/green_chemistry.html#comments Mon, 27 Jun 2005 21:00:00 +0000 Jorge Goncalves http://pontotriplo.org/triplepoint/?p=126 ]]> Very recently, University of Oregon experts have created GEM, Greener Education Materials for Chemists, an online resource dedicated to Green Chemistry. The idea is to develop an interactive collection of laboratory exercises, lecture materials, course syllabi and multimedia content that illustrate chemical concepts, important for green chemistry. Still in the University site, the Green Chemistry Center is worth looking.
For those interested in this topic, two good starting points are the ACS’s Introductory Readings in Green Chemistry and the EPA’s Green Chemistry site.

The idea is that teachers use these resources so that students have a positive learning experience. In the environmental side, the articles about Asbestos and the Chernobyl Nuclear Disaster are worth reading.

A good starting point is Lewis A. Shadoff’s page, All You Wanted to Know about Dioxins. Another excellent source of information is EPA’s page, Dioxin and Related Compounds. The Frequently Asked Questions (FAQs) in this site are very instructive.

At present, the EPA maintains a list of 366 chemicals that are considered extremely hazardous or acutely toxic. For each chemical on the list, EPA provides a profile, containing chemical identity, synonyms, chemical formula, molecular weight, regulatory information, characteristics, health hazard data, fire and explosion hazard data, reactivity, precautions for safe handling, emergency protective equipment and emergency treatment information.
