“…Low accumulation of BTs in Steller sea lion was also supported by the study of Evans et al [43], which indicated that more than 90% of BT intake was excreted through feces and urine. On the contrary, excreted organochlorine compounds were only 9 to 32% of the total intake in humans [44]. These observations, including the results of the present study, suggest that unlike organochlorines, BTs are largely excreted from the body of Steller sea lion and thus accumulated less in this animal.…”

The present study was conducted to examine sex difference, age, and temporal trends of butyltin accumulation and its biomagnification in Steller sea lion (Eumetopias jubatus) collected from Alaska, USA, during 1976-1985 and from Hokkaido, Japan, during 1994 Average concentration of total butyltin compounds (⌺BTs) in the liver of Steller sea lion from Alaska (19 ng/g wet weight) was much lower than those from western and eastern Hokkaido, Japan (150 and 220 ng/g), respectively. This result suggests that Japanese coastal waters are contaminated with BTs in comparison with those of Alaska. In most samples, dibutyltin (DBT) residues were retained at higher levels than tributyltin (TBT), suggesting the degradation of TBT to DBT in the liver. Sex difference and age-dependent accumulation of BTs residues were not found in Steller sea lion. Similarly, no prominent temporal trend in BT concentrations was observed between 1976 and 1985. Nevertheless, the annual consumption of organotin compound was doubled in the United States during the same period. These results suggest that the butyltin compounds are degraded faster than the intake from diet in Steller sea lion. The biomagnification factor of BTs in Steller sea lion was low (0.15-4.6; mean, 0.6), indicating that this animal is unlikely to magnify BTs due to rapid degradation and excretion.

“…There are several reports of animal experiments with high level exposure to PCBs (Grant et al 1971, Hashimoto et al 1976, Hayes et al 1971), but only a few report any low-level exposure data. Price et al (1972) reported pesticide residues and PCB levels in diets, urine, and fecal matter of preadolescent girls. In their experiments, 88% of the ingested PCBs were not excreted and, presumably, they were retained in the body.…”

Abstract.Long-term studies of the excretion of polychlorinated biphenyls (PCBs) through the mother's milk were conducted on an occupationally exposed worker, who worked with PCBs in a capacitor factory.PCBs level in the mother's blood was 57 ppb, a level 10 to 20 times higher than that of non-exposed persons. The other tissues and fluids obtained at time of delivery were also assayed. PCB contents in umbilicus tissues, umbilicus blood and amnion fluid were l/s, 1/4 and 1/8, respectively, the amount found in the mother's blood.An approximate 76% decrease in PCB levels in the milk were noted 16 months after delivery; 200 mg of PCBs were excreted in about 818 liters of milk for this 16-month period.A detailed analysis of the individual components in PCB residues clarified the remarkable changes of the PCB pattern in the blood.Since PCBs in mother's milk were detected in the high concentration range of 0.01 to 0.7 ppm on the whole milk basis in Japan in 1972 (Isono 1972), many research institutes have been investigating the environmental behavior of PCBs. Therefore, the residue levels to be expected and related new information became available from these studies (Takeshita et al. 1974, Hashimoto et al. 1976, Shimada 1976, Nakayama and Aoki 1977, Nishimura et al. 1977).In our investigation of PCBs in blood and mother's milk of non-exposed women for 6 years, we have been studying the problem of breast-feeding through the su-vey of PCBs. The levels of PCB in mother's milk and blood were almost stable from 1972 to 1977; in the range os 0.03 to 0.04 ppm on the whole milk basis (Yakushiji et al. 1977a, b). An average intake of 150 ml/kg of milk per day per baby would mean that each baby would consume approximately 4.5 to 6/zg/kg of PCB's per day. Then one-half the number of Japanese babies would ingest larger

“…The tentative acceptable daily intake in the U. S. has been set at 150 to 300 //g/day 102 , whereas the average intake has been calculated to be only 7 pg/day. 103 However, a study by Price et al 104 on the diet of 8 ' girls in Virginia found that while 4 had only traces of PCB (i.e., less than 0.001 ppm), 4 contained 200, 420, 580, and 840 jug/day. In certain areas, viz., northeast U. S., Japan, and much of Europe, persons eating considerable amounts of fish would be expected to exceed the FDA guidelines.…”
