This is especially true for infants and young children as well as the elderly and those with compromised immune systems. Uncertainties in the assessment of human exposures to exogenous compounds may be reduced using data obtained from dietary and environmental Notice The .

Faster and more cost-effective analytical methods can facilitate the collection of data concerning particular target analytes that may impact human health and the environment. Immunoassays and biosensors can provide fast reliable and cost-effective monitoring and measurement methods 2 . In 1993 the United States National Academy of Sciences NAS issued a major report on pesticides in the diet of children. The report Pesticides in the Diets of .
