A time with microplastic, Daphnia and winter in Finland

My name is Meaw. I come from Thailand, the small tropical country in Asia. I got scholarship from Erasmus Mundus action 2 (SWAP and Transfer project) to do the research about microplastic in freshwater ecosystem for 6 months. I’m interested in microplastic because it’s a pollutant with emerging concern and there are many gaps in research about microplastic. I have done many surveys on microplastic in Thai coastal area, but in here I focus on microplastic testing with aquatic animal in laboratory.

Microplastic and Daphnia

I lived in Finland from Dec 2015-May 2016. During that time, I tried to feed daphnia with fiber microplastic and observe the uptake and depuration behavior of daphnia. In our lab, it is very easy to do the test with daphnia, because the facility is well preparation. So that it is very convenient to do the thing as I plan, even if I did not have an experience with daphnia before.

I also have an opportunity to work together with Spectromics research group in UEF, because we try to develop the technique for observation microplastic inside daphnia. I am very happy to have chance to discuss and share the ideas with the other researchers in our lab group and Spectromics research group. That’s very challenging for me.

Winter in Finland

By the way, because I arrived Finland in winter, I had been asked a lot that “why I come to Finland in winter time?” Actually I did not think about it before I came. Anyway, after one week past I just realized that why everyone asked me. Snow and ice is such normal things in Finland winter and rarely sunshine at that time. It’s very exciting experience for people from tropical country like me. The winter in Finland is longer and colder than in my imagination. That’s why I always ask everyone in the lab “Is it normal weather in Finland?” and now I know that’s normal, after I passed through nearly 4 months of Finnish winter. Even whether in winter make some difficulty of life, but I think that’s worth to get experience like that. I think if I did not stay in Finland at the winter time, I may not see and understand the real Finland. So if someone ask me what the best period to visit Finland, I will recommend winter. Do you agree with me?

SETAC Europe annual meeting in Nantes, France

It’s again the time of the year, when at least part of our group goes to the SETAC (Society of Environmental Toxicology and Chemistry) Europe meeting. This time it was two of us (me and Inna), who decided to go. I love these conferences – they are a combination of travelling, meeting new people, getting brilliant (and not-so-brilliant) research ideas and learning new things. The days in the meetings are long and sometimes a bit overwhelming, you get a great chance to be part of a large research community.

In my opinion, SETAC provides a great opportunity for its student members to become a part of this community. In the meetings, there are several ways to smoothen your way into science community: travel grants, student mentor lunches, lunch seminars, student parties, student advisory council assemblies etc. If you are a Master or PhD student, make sure that you are a member of a professional society, it will make your academic part of life so much easier and more interesting!

As always, there are several interesting things happening simultaneously – it’s so difficult to choose from them. This year, I changed my tactics. Instead of just concentrating on metals, I was running around like crazy to learn more about environmental assessment of cosmetics and personal care products, life cycle assessment (LCA) and emerging contaminants (micro plastics!). If I would have to choose my favorites this year, they would be (1) Graham Merrington from WCA Environment, UK talking about what has happened in risk assessment within past ten years, (2) John Murphy from Queen Mary University of London, UK with an highly intriguing topic of new approaches in ecological effects of metal-contaminated sediments and  (3) Nicolas Pucheux from INERIS, France who’s presentation about implementation of TRIAD approach in ERA of an old lead mine was so interesting that I spent the whole time writing as fast as I could. They were all really inspiring and I feel I got a lot of new ideas and perspectives to think about.

Another nice thing in participating international conferences is travelling, and Nantes was great for that. You can’t go to Nantes without riding the Grand Elephant (picture below). Food was great, people were nice, buildings were pretty and the prices affordable. What’s there not to like!  Next year, SETAC Europe Annual Meeting is held in Brussels (https://www.setac.org/events/event_list.asp). And the SETAC World Congress will be at the end of this year in Orlando, Florida (https://orlando.setac.org/). Not a bad place to go in November!

Tervetuloa! Welcome!

Tervetuloa uuteen Itä-Suomen yliopiston akvaattisen ekotoksikologian tutkimusryhmän blogiin. Käsittelemme blogissa tutkimuksen ja tutkijan elämän ajankohtaisia asioita sekä tutkimusryhmämme kuulumisia. Julkaisemme mielellään tekstejä myös meiltä muihin tehtäviin siirtyneiltä ihmisiltä!

Welcome to read the new blog from the Aquatic Ecotoxicology research group at UEF. In here, we shall share the latest news and activities related to our work. We also warmly welcome posts from  people that have previously worked in our group, to see what kind of jobs you can do as an ecotoxicologist.
