toxicity comparisons

[Rtom45]

Can anyone provide a link to a website that compares toxicity of commonly used lawn care chemicals to household products? I'd like the LD50 of things like table salt, vinegar, aspirin,.... At a college, everyone thinks they know everything and I need some facts to talk common sense to them.
Thanks in advance for your help.

Try www.prginc.com/Borates/using-borates.html. This page contains a small list of common materials and different pesticides for comparison. It doesn't contain any herbicides but if you have the LD50 could see how they compare.

Let me know if these help.

www.kellysolutions.com has MSDS's

This is a good site for pesticide info:

And this is one that I've used for MSDS and label info:
