New method to filter out the microplastic effect

While research into the effects of microplastics has expanded greatly in the past decade, important questions about what concentrations are hazardous in water still remain unanswered. Moreover, water contains naturally occurring suspended particles, such as clay, that are of the same size as microplastic and may be equally harmful to aquatic life when present at high concentrations. With that in …

Where do microplastics go in the world’s oceans? ACES students in search for answers in Pacific marine snow

Microplastics are small (less than 5 mm) pieces of plastic litter. They mainly originate from the breakdown of plastic debris in rivers and seas, but are also flushed out from other sources such as personal hygiene products that contain microbeads. Once in the ocean, the fate of microplastics is largely unknown. To address that question, PhD students Zandra Gerdes and Sophia …

ACES scientists involved in large research grant for developing green chemistry

From surfer shorts to surgical drapes: New framework to reduce harmful chemicals like PFAS added to consumer goods, phase out non-essentials

Human exposure to unnecessary and potentially harmful chemicals could be greatly reduced if manufacturers add chemicals only when they are truly essential in terms of health, safety and functioning of society. That’s the conclusion of a study published in Environmental Science: Processes & Impacts. In this study, researchers propose a framework based on the concept of “essential use” to determine …

A month in one of the world’s most polluted megacities – a scientist’s story

Delhi is like nowhere I’ve been before. The streets burst with people and noise and life. Clothes are brighter than elsewhere; the smells are stronger and deeper and ever changing. The food has more flavour. The soundscape – people shouting, car horns honking and the general background din – is completely unrelenting. It’s an onslaught to the senses. Traffic flows …

Risk assessment of new chemicals by EU is not transparent enough say ACES researchers

REACH is considered by many to be the best chemicals legislation in the world. But the high demands on the producers and importers are ineffective if the data they submit to the European Chemicals Agency is not being examined. In a new policy brief, researchers at ACES call for greater transparency and better control within REACH. The European chemicals legislation …

Antifouling paints used on leisure boats are sources of contaminants to the environment

The concentration of antifouling paints used on leisure boats exceeds safety values in both water, sediment and soil, shows a new PhD thesis from ACES. “My research shows that the use of antifouling paints pollutes the environment, not only when the boats are in the water but also when the hulls are subjected to maintenance activities on land. The results …

Clues of carbon release from thawing permafrost found in Arctic rivers

Arctic rivers may hold vital clues to the accelerated release of carbon stored in Arctic permafrost, shows a new study by researchers from ACES published in the Proceedings of the National Academy of Sciences of the USA. “Rivers transport carbon from different sources in their catchments, including carbon mobilized from thawing permafrost or collapsing peat, as well as carbon from …

Health risks of chemical cocktails underestimated shows new report

The cocktail of man-made chemicals that we are exposed to daily is a health risk which current regulations and risk assessment overlook. This is the conclusion of the EU Horizon 2020 EDC-MixRisk project that is now being presented.  We are exposed to a large number of man-made chemicals in our everyday life. This creates combinations of chemical mixtures, to which …
