Pilot studies of concentrations of phthalic acid esters in combined feedstuffs (n = 21) and porcine (n = 6) and bovine (n = 6) adipose tissues were conducted in the district of Hodonin in 1997. The samples were collected repeatedly in two feed processing plants and three swine and two cattle farms. Mean concentrations (mg/kg of original sample) of di-n-butyl phthalate (DBP), di-2-ethylhexyl phthalate (DEHP) and sum of DBP + DEHP in combined feedstuffs were 0.207, 0.216 and 0.423, respectively. The corresponding values for porcine adipose tissue (subcutaneous back fat) were 3.363, 0.505 and 3.868, respectively, and for bovine adipose tissue (fat capsule of right kidney) 2.537, 0.790 and 3.327, respectively. The concentration of the sum of DBP + DEHP in feedstuffs permissible in the Czech Republic, (4.0 mg/kg of original sample) was exceeded in three of six pigs (4.260, 4.520, 6.920) and one of six cows (4.750). The widespread environmental contamination by PAEs, their adverse effects on live organisms and our findings of impermissible concentrations in adipose tissues of food animals rank them among topical hazardous contaminants also in the Czech Republic
