In general, the larger organophosphate esters, such as cumylphenyl diphenyl phosphate, concentrate more in fish because they have higher Kow values and hence, tend to partition to fat, while smaller ones, such as triphenyl phosphate, concentrate less because they have lower Kow values and do not partition. In fish, organophosphate esters appear to be more bioavailable when sediments are not present (Huckins et al. 1991), but chronomids appear to be able to bioaccumulate organophosphate esters from the sediments (Muir et al. 1983b, 1985).

Organophosphate ester components of hydraulic fluids such as triphenyl phosphate, nonylphenyl diphenyl phosphate, and cumylphenyl phosphate also have been detected in fish concentrations of 0.1-0.9 pg/g of fish tissue were detected principally near manufacturing facilities, while fish caught in other areas generally had concentrations below the detection limit (0.1 pg/g) (Mayer et al. 1981). In a market basket survey, tributyl phosphate was found to be present in 2% of the foods analyzed between April 1982 and April 1984 (Gunderson 1988). Intakes of tributylphosphate were estimated to be a maximum of 38.9 ng/kg body weight/day for 6- to 11-month-old children.
