Are drugs harmful for the environment?

11.06.2003


Medicines released into the environment may be a risk to living species in the long term. Jeanne Garric’s ecotoxicology team at Cemagref Lyon has shown that certain molecules disrupt reproduction, embryo development and growth of representative organisms in aquatic environments. Toxicity tests have been conducted in the laboratory on Daphnia, Rotifera and zebra fish under standard protocols. Active pharmaceuticals ingredients (APIs) concentrations in the environment however are found to be 1000 to 100,000 times too low to cause acute toxicity.



Cemagref scientists have tested a dozen of the most widely used APIs in France and Europe, covering a wide spectrum of molecular diversity. The research was carried out as part of the European Rempharmawater research programme and French Enimed programme under the PNETOX national ecotoxicology programme funded by the environment ministry.

In France and Europe as a whole, most drugs swallowed end up in rivers after passing through a wastewater treatment station. Any drug not entirely broken down will reach surface waters. For this reason degradability and biodegradability in STP and receiving ecosystem is one of the important key parameters to understand for the risk assessment of such APIs.. But even in small amounts, a drug, may have toxic effects. Very low concentrations of the some b-blockers, in surface waters may affect invertebrate reproduction.


Answering questions as to the environmental impact of medicines has become vitally important, in terms of sustainable development. Mutual interactions between different drugs and their effects on sediments also needs investigating. This is a major challenge, because a continuous stream of such molecules are pouring into the environment.

Im Focus: Carbon Nanotubes Turn Electrical Current into Light-emitting Quasi-particles

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects

A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
