    Abstract:
    Ten healthy patients with term pregnancy resolved by abdominal via. During the surgical procedure samples of umbilical chord serum and maternal adipose tissue, were taken. In all the samples, together with the maternal milk collected the day 10 of puerperium, the concentrations of the following organochlorine pesticides, were measured up: (PCC); beta-BHC; gamma-BHC; heptachloride; aldrin; dieldrin, DDE, DDD, DDT and methoxychloride. The identification and quantification of pesticides was done by the comparison with standards certified by NIST (National Institute of Standard Technology). The general characteristics of the participants were: primigestas of 24.1 years aged, married and of a low socioeconomical level. As to the neonates, of 39 weeks of gestational age, female sex; 3,311 g of corporal weight and size of 51.1 cm. In all the analyzed samples at least one of the organochlorine pesticides was present. The results of correlation analysis between DDT concentration, present in the maternal serum with those identified in the adipose tissue and serum from the umbilical chord were highly significant: a = 0.97 and 0.87, respectively. In the maternal milk the highest concentrations of total DDT, were found, average of 2053 ng/g lipidic base, which is 2.8 times more of daily accepted intake. Likewise, DDT concentration in maternal serum kept exponential relation, growing with age (a = 0.99).
