Further, trichloroacetic acid (TCA) can be formed as a minor product in the atmospheric deg-radation of some chlorinated solvents.

Although the results of these studies suggest that TCA levels in soils could not be explained by precipitation alone, the European Union Risk Assessment on nevertheless concluded that “it is considered unlikely that depo-sition of TCA from the atmosphere will by itself lead to levels of TCA in soil that pose a risk for ter-restrial organisms”.

iGEM Europe


The European Teams

This year, Oxford has been researching the European contribution to the iGEM competition.

[Paragraph from Phil re why this is interesting, e.g. Oxford is entering for the first time, being a little late to the party, it's interesting to see at what stage we are joining etc].

Our team has also founded the iGEM Europe Facebook page this year: https://www.facebook.com/europeigem to help facilitate communication and collaboration between European iGEM teams. The page has over 100 likes and has been useful as a platform for exchange of ideas, help, and inspiration between teams.

We've also been working with the Imperial iGEM team, who have been doing some interesting research into languages and iGEM, an aspect which closely relates to our own interest in European teams. Check out their work here...[insert URL]...
Statistics

We have also analysed statistics to spot trends over recent years in European iGEM participation. It's great to see that participation has been increasing steadily between 2006 and 2014, and that every year European teams have performed strongly and brought some great ideas to the competition. You can see some of the results of our research below...
