The distribution characteristics of organo-halogens in apple and their sources were studied by neutron activation analysis combined with statistical analysis. The results indicated that concentrations of organo-halogens in apple were in the order of organo-chlorine >> organo-bromine > organo-iodine
and concentrations of the organo-chlorine in four parts of apple were in the order of seed >> peel >> endocarp ≥ pulp. Also
the organo-chlorine
-bromine and -iodine in apple were found to have different sources. The latter two were mainly from naturally synthetic products by plant itself
while the former was mainly from anthropogenic pollutants.
