Environmental Concerns
Sulfonic acid derivatives are generally not derived from natural precursors and tend to biodegrade slowly. Some, such as perfluorooctane sulfonic acid, have been detected in the serum of humans. This should be not surprising as all organic fluorine compounds have extreme stability, and low to zero biodegradability. Many are intended to withstand harshest chemical conditions, for example teflon. The nonfluorinated sulfonic acids tend to have low toxicities.

Famous quotes containing the word concerns:
“New inventions can and will be made; however, nothing new can be thought of that concerns moral man. Everything has already been thought and said which at best we can express in different forms and give new expressions to.”
