– This is a wake-up call that this substance and several other pharmaceuticals are so difficult to break down, says Jan Christiansson, the officer in charge at the Swedish EPA.
The uniquely large-scale screening has examined as many as 101 drugs and their levels in wastewater purification plants, surface water, drinking water, and fish caught in the wild. The study focused on effluents from densely populated areas with an emphasis on incoming and outgoing wastewater from wastewater treatment plants and the waterways and lakes that are downstream from these treatment plants. Tissue samples from fish (perch) were also included from waters downstream from two treatment plants and from two control lakes. Also included were analyses of drugs in drinking water from two cities.
The results show that many substances, including diclofenac, are released with little impact from the wastewater treatment plants . Seven samples with ten perch in each sample were analyzed, and as many as 23 of 101 drugs that were analyzed were found in these samples.
“We’re aware of the problem with diclofenac. The study shows further that there are other compounds than diclofenac that we should be monitoring and studying more closely. After all, these are fish caught in the wild, and the samples show that there are drugs that are difficult to break down, that make it through wastewater treatment plants , and that they are bioconcentrated by the fish. Since we found so many substances in the fish samples, this is something we need to look at more closely,” says Jerker Fick, Umeå University.
As the study is so broad and covers such an unusually large number of pharmaceuticals, the findings are highly informative. The study shows that 92 of the 101 drugs could be detected in incoming wastewater and that as many as 85 could be detected in outgoing, treated wastewater.
“To alleviate these problems we need to improve our environmental adaptation of pharmaceuticals compared with today. This means that producers need to take their responsibility. Moreover, the behavior of the general public plays a role. Everyone needs to return leftover drugs to the pharmacy and not flush them down the toilet. What’s more, wastewater plants need to do a better job of breaking down compounds that are hard to break down, so they don’t jeopardize our health and environment via direct emissions or via sludge from wastewater treatment,” says Jan Christiansson, Swedish EPA.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
