Additional TEAM studies indicate that while people are using products containing organic chemicals, they can expose themselves and others to very high pollutant levels, and elevated concentrations can persist in the air long after the activity is completed.
The ability of organic chemicals to cause health effects varies greatly from those that are highly toxic, to those with no known health effect.

 Chemicals - SkepticWiki   (Site not responding. Last check: )
The meaning of “organic” in advertising and common usage is difficult to state definitively; some have criticized the common use of the word as a meaningless, feel-good adjective.
Synthetic chemicals were developed for applications in which no natural chemical could possibly work: Polytetrafluoroethylene was originally used to contain strong acids that would dissolve ordinary containers; cyanoacrylate adhesives could hold hundreds of pounds with one drop, and “mauve” became a newly popular textile color.
Since we cannot avoid chemicals, and it is too difficult to be knowledgeable about the health effects of all chemicals, some may resort to the simple expedient of avoiding synthetic chemicals, reasoning that these are more likely to be dangerous.

 Organic Chemistry
Organic chemicals (also known as hydrocarbons) contain carbon bonded to hydrogen (some also contain other elements).
Basic organic chemistry can be thought of as a molecular Erector Set, if you know the number of carbon atoms and the type of bonds in a molecule, you can build the molecular structure.
To complete the hydrocarbon name, the prefix is attached to the ending of the root word (drop the alk- from the words alkane, alkene or alkyne) to describe the type of bonding on the molecule.

 Organic Chemicals - A Definition - Seventh Generation
The amino acids and proteins that are the basis of all life on Earth are organic chemicals.
However, these are synthetic organic chemicals, also called "petrochemicals", and they include some of the most valuable medical and industrial substances ever known, they also include some of the most hazardous substances ever made.
The reason some synthetic organic chemicals are so dangerous involves some serious chemistry, but it boils down to this: in nature, each natural compound (and there are millions) is balanced by an associated natural enzyme that can break it down and cause it to harmlessly decompose.

 Better Flavors through Organic Chemistry   (Site not responding. Last check: )
Being a flavor chemist (or flavorist) can be an interesting, fun, and lucrative job—creating flavors for a variety of foods from beverages, to the main course, to dessert!  Training is of utmost importance, and practitioners must apprentice with a senior flavorist for several years before obtaining certification as a flavorist.
Organic chemists make new chemical flavors, are often consulted about the availability of unique flavor chemicals, and conduct the synthesis of known flavor chemicals, often in a “kilo” lab (kilogram scale using multiLITER equipment).
Organic texts often cite flavor chemicals such as vanillin from vanilla as examples of naturally occurring organic chemicals that we encounter every day.
