When the word ‘oil’ is mentioned, people usually think of huge quantities of an unsightly-looking black mass. It’s easy to show the environmental impact of the oil industry, just show footage of shipping accidents and people understand that it’s a big deal. However, when the word ‘drugs’ is mentioned, it’s harder to visualise the impact straight away. Everyone imagines something very small and clean. However, we don’t need to be fooled. Even a small mass can have a big environmental impact. So let’s take a closer look.
Pharmaceutical Pollution
We are currently facing a significant environmental problem due to the presence of drug residues in waste water. These substances, which enter the sewage system from households and healthcare facilities, can have a significant impact on water quality and ecosystems. Of particular concern are antibiotics, which can contribute to the emergence of drug-resistant bacteria. However, scientists at the Faculty of Chemical and Food Technology of the Slovak University of Technology (STU) in Bratislava are already actively working on developing innovative methods that could effectively remove these harmful substances from water.
Methods of removing drug residues
Researchers at STU are investigating different approaches to clean water of drug residues, drugs, viruses and bacteria. Methods being studied include chemical reagents, nano-diamond layers, ironates, photoactive powders, and biological methods like aquatic plants. These technologies could greatly reduce pollutants in wastewater and prevent environmental harm.
Significant impact on health and ecosystems
Drug residues in wastewater pose a risk not only to human health but also to aquatic organisms. If these substances are inadequately disposed of, they can enter rivers, lakes and eventually drinking water. Long-term exposure to lower concentrations of pharmaceuticals can have unpredictable effects on aquatic ecosystems, including disruption of reproductive cycles and growth of organisms.
The future of research and innovation
Research on cleaning water of drug residues is an important step towards protecting the environment and public health. Innovative methods being developed by a team of scientists at STU could soon be implemented in practice, significantly reducing the risk of contamination of water sources. Some of these technologies are already at the patenting stage, which underlines their uniqueness and potential for global application.
Conclusion
The issue of drug residues in wastewater is a global challenge that demands collaboration among researchers, regulators, and the public. Responsible pharmaceutical use and investment in new treatment technologies are vital for a sustainable water future.
