WebAbstract: Over the past 20 years, a variety of models have been developed to simulate the bioconcentration of hydrophobic organic chemicals by fish. These models differ not only in the processes they address but also in the way a given process is described. Processes described by these models include chemical diffusion through the gill's interlamellar … WebGills in fish Water is capable of holding only low concentrations of oxygen, so fish need a different type of exchange system.
