Angel Jessieleena, research on fate of microplastics on surface waters in Chennai

Angel Jessieleena A had an enriching 3-month research exchange program at RWTH Aachen University, Germany, as she delves into the source and fate of #microplastics at Indian Institute of Technology, Madras, Chennai.

Angel’s gained valuable insights in focus and organization, significantly impacting her personal and professional growth through their research exchange in Germany.

You can read their full testimonial is below:

“My name is Angel Jessieleena A, and I’m a PhD student at IIT Madras, Chennai. My area of research is to investigate the source and fate of microplastics present in aquatic systems. In this report, I will share my experience with a 3-month research exchange program at RWTH Aachen University in Germany.

The main purpose of my visit was to utilize an instrument named micro-FTIR, which helps in the analysis of microplastics.

To begin with, let me first give you all a brief background about my area of research and my intent to visit. My doctoral research work is in the field of microplastics, focusing largely on the environmental monitoring of the surface waters of Chennai, India. In order to conduct a qualitative analysis of microplastics, Fourier Transform Infrared Spectrometer (FTIR) is used. However, it becomes impossible to use FTIR for the analysis when the microplastics of interest are less than 500 microns. There comes the need for a sophisticated instrument called micro-FTIR wherein a microscope comes along with the FTIR. This enables the user to focus on the microplastics through the microscope and parallelly conduct FTIR analysis to know the chemical composition of microplastics. However, this instrument is not available in our institute, but in order to analyse smaller microplastics (<500 micron in size) that are reportedly predominant in surface waters, micro-FTIR is essential.

Since Dr. Schwarzbauer’s lab at the Institute of Geology and Geochemistry of Petroleum and Coal, RWTH Aachen University is having the instrument, we (me and my supervisor) have decided that it is better for me to make a research visit to Germany. This is how my plan to visit RWTH Aachen University started. Later on, during our search to widen the exposure and also to gain knowledge about the experimental works that are being carried out in the other institutes of RWTH Aachen University, we came across ‘The Institute of Hydraulic Engineering and Water Resources Management (IWW)’, headed by Prof. Schüttrumpf. Wherein I had the opportunity to conduct experiments to understand the settling behavior of microplastics, which was inspired by the research work of Dr. Waldschlager. I’m very much thankful to both Dr. Waldschlager and Max for helping me out throughout this work.

Now coming to my experience, these three months had a great impact on both my personal and professional life.

I’m someone who always does things in a hurried manner, assuming that I would save time by rushing it up. But when I went to Germany, I kind of understood that no one there is actually rushing their work. Instead, they do one task at a time but with complete focus. Whereas many a times I felt that since I’m rushing my work and doing multiple things parallely, my focus will not be 100 % at the work I’m doing. This is because at the back of my mind I would be always thinking that I have some other things to do. This would ultimately help me finish the job but not with a perfection.

Another important habit I learnt is ‘the art of organization’. Since I’m someone who rush up things, I just sometimes keep things randomly with a prime focus of just finishing up the work. This habit would eventually make me spend more time to locate my things/materials. This not only causes loss of time but creates unwanted mental stress. I also realized that Germans are more into maintaining the things and keeping it clean. I see people spending so much time cleaning a single glassware and maintaining it very properly. I think I was lacking in that and now I’m trying my best to maintain my things and keep it clean.

Apart from these, I learnt many more things. I would say that these three months research stay at Aachen have made me a better person both in my personal and professional life.

Working in both the institutes was a highly rewarding experience. For a microplastic researcher, specially coming from developing countries like India, working with micro-FTIR was always a dream since it is pricey. Special thanks to Christina for helping me to learn the instrument’s operational and other details. Though I could not analyse all the samples due to time constraints, I was able to analyse samples that are of high importance. Therefore, for those planning to do a similar kind of research visit, my kind advice is to plan for at least a 6-month visit so that you would not need to rush up your work like I had to do.

So, I would recommend all my colleagues to take up the available opportunities and get immersed in a new experience. I’m sure that experience like this will definitely better their personal and professional life. Last but not least, I’m very thankful to all my colleagues and IGCS team members for their kind support throughout my stay there.

Danke!”

Nina Engels, Understanding flood-induced contamination in the Adyar and Cooum river systems, India

Nina Engels is an IGCS research exchange scholar from Neotectonics and Natural Hazards Group at RWTH Aachen University, who was staying at Indian Institute of Technology, Madras, Chennai, India between 20. February until 15. March 2023. They were doing research on the topic of “Coastal and estuarine sediment archives for flood-induced pollution in subtropic/tropic areas” under the supervision of IIT Madras’ Prof. Dr. Sannasiraj S A from the Department of Ocean Engineering, and Prof. Dr. Indumathi M. Nambi, from the Department of Civil Engineering.

Nina’s stated the following about their research exchange in India:

“The aim of our study and my research stay in Chennai, India, was to identify suitable sedimentary archives at local river systems to learn about flood-induced transport, distribution, deposition, dilution and enrichment of contaminants. Highly populated regions along the south-eastern Indian coastline are particularly vulnerable to periodic and aperiodic flood events. With ongoing global warming, flood-related impacts will increase in frequency and amplitude. During flood events, anthropogenic pollutants, adherent to sediments, get deposited in the catchment areas and can pose a threat to humans and the environment. As little is known about the flood-induced contamination, the highly polluted and flood-affected river systems of Adyar and Cooum in Chennai have been chosen as study area. We aimed to identify deposition areas and pollution indicators that are suitable to reconstruct the river pollution history.

To approach the research questions, field and laboratory work was carried out in February and March 2023. It was a follow-up campaign of a preceding campaign that has been conducted in 2019. We took sediment and river water samples along the Adyar and Cooum rivers as well as the Buckingham Canal. The sediment samples were collected using a geoslicer, a tool designed for collecting nearly undisturbed vertical sections of sediment deposits. The water samples were processed in the IGCS lab facilities at the IIT Madras. Currently, geochemical analyses are carried out at the Institute of Organic Biogeochemistry in Geosystems at RWTH Aachen and results will be finalized at the beginning of 2024. Challenges we faced during the field- and lab work were related to finding and accessing suitable sampling sites, coping with time-consuming processes in the lab and fieldwork organization. As we worked closely with local staff of the IIT, we were always accompanied in the field by a student who could speak the local language, Tamil. This gave us the opportunity to communicate with local people in Chennai and ask about their experiences with flood events. Although we had to adjust some locations, we were able to collect samples at most of the planned sampling locations to get a better understanding of the flood-induced contamination.

A research stay in India is a unique experience on many different levels. Not only is it interesting research-related, but also getting to know the Indian culture and people more closely, working in international teams on current sustainability challenges and exploring this amazing country are enriching and valuable experiences. One of my highlights was our daily evening stroll around the calm and beautiful IIT campus after having a very tasteful Indian dinner. That gave us the opportunity to discuss what we experienced during the day, finding solutions to problems we encountered and just enjoying the atmosphere on campus.”
