Chlorinated pesticides concentration factors

Table 6.4. Concentration factors reported for chlorinated pesticides in water and fish.

In the initial period after the penetration into the organism, pesticides are distributed by the blood circulation so that their concentration in particular tissues depends on the level of the blood supply. For example, in the liver or in the brain, their concentration is higher than that in the fat tissue. The final distribution of chlorinated hydrocarbons is, however, governed by their solubility in fats which is much higher than that in water, so that concentrations in the lipid tissue may be higher by a factor of 100 to 300 as compared to those in the blood.
