Toxic Chemicals

There is information about safety, poisons, toxins, carcinogens, testing procedures, regulations. Learn how to recognize hazardous substances and avoid laboratory accidents. Links to toxic chemical journals and software are included.
Common Household Chemicals - Dangerous Mixtures
Labs have lists of chemicals that don't go together, but it isn't as easy to avoid dangerous mixtures with home chemicals because they aren't pure substances. Here's some help. Be safe and don't mix these common household chemicals.
What Is the Most Poisonous Chemical Compound?
How poisonous something is depends a lot on how it's administered and a several other factors, but this list will give you a general look at some of the most toxic substances known to man.
Chemical Weapons and Warfare Agents
Get basic information about chemical weapons and learn what you can do to protect yourself in the event of a chemical attack.
DEET Chemistry
Learn about the insect repellent called DEET. See its chemical structure, find out how it works, get information about the risks of using DEET, and find out how to reduce your need for bug spray.
Do You Add Sulfuric Acid to Water or Water to Sulfuric Acid?
It's important to add sulfuric acid to water and not water to concentrated sulfuric acid. Here's an explanation of why you don't want to make a mistake and some mnemonics that might help you remember how to play it safe in the chemistry lab.
Flame Retardant People
Learn about the health effects of polybrominated diphenyl ether (PBDE), a common flame retardant, and efforts to ban further use of certain forms of the chemical.
Incompatible Chemical Mixtures
Here's a list of chemicals that you don't want to accidentally mix, together with brief statements about the expected reactions. Use this information to avoid accidents and ensure safe storage and handling of potentially dangerous substances, both at work and at home.
