Model approach for estimating potato pesticide bioconcentration factor. [PDF]
, 2016 e presented a model that estimates the bioconcentration factor (BCF) of pesticides in potatoes supposing that the pesticide in the soil solution is absorbed by the potato by passive diffusion, following Fick?s second law.

Exposure to novel entities in the environment now exceeds our capacity to evaluate the risk of each chemical under traditional frameworks. Detecting, prioritizing and identifying thousands of anthropogenically-derived chemicals already present in the environment is a key challenge to understand this planetary boundary.

Bioconcentration Factor Hydrophobicity Cutoff: An Artificial Phenomenon Reconstructed
, 2016 The debate on whether highly hydrophobic organic chemicals (with log Kow > 5−6) bioconcentrate less than may be expected from their hydrophobicity is still not settled.

An assessment of the bioaccumulation of estrone in Daphnia magna [PDF]
, 2004 The bioaccumulation of estrone by Daphnia magna was determined. Direct uptake via the aqueous medium occurred within the first 16 hours. A bioconcentration factor of 228 was established over all temporal periods.
