A tоxicоlоgist is studying populаtion of а smаll minnow that live in a pond near an industrial site that uses and discharges a variety of chemicals. They notice that an unusually high proportion of the minnows have tumors on their livers. Why might this be of concern? I. The minnows are important members of an ecosystem – if something is affecting their health it might impact the stability of the whole ecosystem. II. If the compounds that are making their way into the pond they may be making their way into other materials to which humans are exposed (air, well water, soil). The effect on fish might be an early warning for potential impacts on humans. III. There is no reason to be concerned about this, because fish and humans are very different. IV. There would only be reason to worry if this were happening in walleye or bass (fish humans eat).
