Global changes, such as climate warming and stratospheric ozone depletion, are increasingly noticeable. Therefore, there is a need for scientists to have reliable information about atmospheric and stratospheric processes .

Atlantic Bluefin Tuna is a much sought after delicacy. Due to huge fishing pressure, tuna stocks have decreased dramatically . There are now signs of recovery, according to the International Commission for the Conservation of Atlantic Tunas .

Global warming is leading to an increase in mosquito-borne diseases such as malaria . It is considered the plague of developing countries. According to the World Health Organisation , it is responsible for one child death every minute.

Grass could be used to produce biofuels. The advantage of using grass crops is that they can be grown in marginal lands that would otherwise not be used .

Urban mining is increasingly being taken seriously by industry because it gives access to materials—such as expensive metals used in electronics—that are buried in waste tips and landfills.

What happens to research findings once the researchers have gone away? A web site run from the University of Stuttgart in Germany offers scientists an opportunity to bring their own data from completed research project on environmental and health risks and contribute to an Integrated Environmental Health Impact Assessment System, dubbed IEHIAS .

Twenty five years ago, the German chemist Michael Braungart developed a new approach to recycling, now called "Cradle to Cradle" or "C2C" after the book, Cradle to Cradle: Remaking the Way We Make Things, which he and the American architect William McDonough published in 2002.

In Europe, irrigated agriculture is the chief water consumer for food production. Yet water resources are in limited supply.  One way out of this problem is to take more care with the water we use , and reduce the estimated 60% water waste.

Water is one of humanity’s most pressing issues. Do we have enough of it for drinking, for farming or for industry? Too much, in the shape of flooding? Or too little, in the form of drought? The WATCH project, funded by the EU, was designed to give us better answers to questions of water management .

Tyres are well suited for recycling. They are easy to collect and do not require any costly sorting process.  However, in Europe, still only about 50% of the tyres are recycled .

Silver has been used as biocide for medical purposes since the 1930s. Today nanometric size silver particles are used to prevent unpleasant odour caused by bacteria in sport shirts or socks .

People living in Arctic areas can be more sensitive to pollutants due to their genetics , says researcher Arja Rautio at the Centre for Arctic Medicine in the University of Oulu , Finland.

Sea bass or sea bream, by far the most consumed fish species around the Mediterranean area, increasingly originate from aquaculture.

We can blame all sorts of things on the weather. But a stomach bug?  It seems unlikely. Yet, scientists say greater quantities of rainfall and bigger storms will lead to more stomach upsets in parts of Europe.

In 2009, Czech and Slovak scientists involved in EU funded Envirisk project, completed their analysis of the impact of air impurity on population health, based on 15 years of past data available from their respective countries.

Eco-symbiosis is en vogue. Indeed, this approach consists in using waste from one industry as raw material for another. It appears like an ideal solution for one of the most challenging type of pollution: oil spills .

Nevertheless Margulis is best known for her theory of symbiogenesis, which challenges a central tenet of neodarwinism.

Membranes for water purification are used in many applications and different types of membranes are being developed at the moment. No membrane can filter and purify water entirely, but improvements using novel kinds of membranes are made.

Dr. Anne Beeldens and colleagues at the Belgian Road Research Centre have tested air purification efficiency by TiO2 NP-containing pavement blocks on parking lanes in Antwerp.

In the young nanoecotoxicology field researchers such as Dr. Irina Blinova and colleagues at the National Institute of Chemical Physics and Biophysics in Estonia evaluate nanoparticles’ (NPs) interaction with their environment.
