Pollutants found in fish we eat can compromise the body's defense. Ten of the pollutants of this study were found in human organisms which means that these components are present in the food chain. Indeed, nine of these pollutants are found in tuna, the most widely eaten fish in the world. Their presence in the ocen is due to runoff with rainwater or wasterwater discharges into rivers. The most vulnerable people are newborn babies, because they have few P-GP in their young cells and they can drink contaminated breast milk. Moreover, we don't know all the effects on humans, for example in case of contact with other medications which could cause an unexpected chemical reaction. To conclude, chemical products created to make life easier, can have unfamiliar behaviour and in the end deteriorate health.
