Often overlooked is the possibility that derivatization also provides qualitative information. For example, assume the suspect compound is a herbicide such as 2,4-D (2,4-dichlorophenoxy acetic acid). As such, this compound cannot be reasonably chromatographed and detected at trace levels. Therefore, it is customarily converted to the corresponding methyl ester and analysis is based upon comparison to standards of the corresponding methyl ester. The qualitative information available from this sequence is ... 

Exposure of workers (applicators and mixer-loaders) to 2,4-D [(2,4-dichlorophenoxy)acetic acid], when applied to wheat under normal use, was determined by measuring urinary excretion of... 

The potential for environmental contamination continues to come from families of herbicides that have been used for years. The chlorophenoxy herbicides such as 2,4-D (2,4-dichlorophenoxy acetic acid) and 2,4,5-T (2,4,5-trichlorophenoxy-acetic acid) (Figure 5.1) are systemic acting compounds to control broadleaf plants and have been in use since the 1940s. The oral toxicities of these compounds are low.

Today, more modem and less harmful pesticides, such as Malathion and Cyfluthrin, are produced from similar hydrocarbon chemicals. These pesticides reduce insect damage to crops and thus contribute to both the quantity and quality of food and reduce its cost. Growth regulating herbicides such as 2,4,D (2,4,-dichlorophenoxy acetic acid) are hydrocarbon-derived chemicals used to increase crop production by the control of competition from weeds. Hydrocarbon derived chemicals contribute heavily to the productivity of modem farming methods.
