Abstract
The influences of Residual Pesticides for human health or environment have been a very important problem.
The Welfare Ministry of Japan has regulated another 34 standards for the residues, adding to the conventional 26 standards, because the amounts of agricultural products imported from the foreign countries have increased year by year and the consumers' concern for the safety of the agricultural products has increased rapidly.
This study proposes a new nondestructive method to measure the quantity of residual pesticides on vegetable surfaces by FT-IR of attenuated total reflection method.
The main results of this study are as follows.
(1) The active element of residual pesticides can be discriminated by a set of characteristic absorbance bands of pesticide.
(2) An adequate correlation was observed between the A.T.R. method values and conventional G.C. method values.
(3) FT-IR-A.T.R. method takes less time to detect than conventional G.C. method.
(4) These technologies of this study are expected to be very useful to develop a measuring system for the food safety.
