Determination of 1,2 Dichloroethane

1,2 Dichloroethane has been used for many years as a fumigant, usually in mixture with tetrachloride, for raw grain piles in warehouses. It has widespread use. It is thought to be less used worldwide today.

1,2 Dichloroethane is absorbed more strongly in foods than tetrachloride. In the studies conducted, no data was obtained indicating that they reacted with food components. The results obtained from the studies, starting from the grain to the final product, in the products that were ventilated for a few weeks after the first fumigation:

In the grain; While 10 - 25 ppm
In flour; 2 - 11 ppm
In bread; 0.05 ppm

Methods using gas chromatography are preferred for the detection of 1,2 Dichloroethane residue in foods.
