A recent joint Australian-Italian study has found traces of the anti-depressant, fluoxetine, also known as Prozac, in lakes and rivers, potentially affecting freshwater fish. The study, conducted by Monash University and the University of Tuscia, examined the impact of pharmaceutical residues on fish in Australian freshwater bodies. Fluoxetine, a popular anti-depressant, is among the drugs detected in the water.
Pharmaceutical residues in waterways come from the excretion of medication by patients, which ends up in wastewater treatment plants and eventually in aquatic life. Even though these treatment plants are not designed to filter out pharmaceuticals, researchers found that fish exposed to low levels of fluoxetine experienced changes in their reproductive and fertility traits.
Besides anti-depressants, other pharmaceuticals, microplastics, and heavy metals like arsenic and copper can also pollute freshwater environments. Scientists suggest modifying water treatment processes to filter out pharmaceuticals and engaging governments to establish regulations. Improving monitoring and compliance standards may help reduce the impact of these pollutants on aquatic life.
Further research is needed to understand the full extent of the harm these pollutants can cause, but experts emphasize the importance of taking action to prevent these chemicals from entering the environment. By raising awareness and advocating for better water treatment practices, we can work towards protecting freshwater ecosystems from the negative effects of pharmaceutical contamination.
