Chemical Risks —

How do chemicals affect health, ecosystems and the economy? How can we create a better understanding and greater awareness of pollutant risks?

The challenges

Chemicals in the environment

Chemicals in the environment are an increasing threat to ecosystems and human health. They enter soil, water and air through industry, agriculture and everyday use, where they often persist for years or decades. These include pesticides, pharmaceutical residues, microplastics and so-called “forever chemicals” PFAS (per- and polyfluoroalkyl substances).

Many of these substances are toxic, have endocrine disrupting effects or persist in the environment and can accumulate in food chains. They not only lead to a loss of biodiversity, but can also endanger human health – for example through contaminated drinking water, contaminated food or air.

“Given the growing trend towards biomaterials, it is crucial to bring the chemical safety of both conventional plastics and bio-based, biodegradable alternatives to the political agenda.”

Our research

Ways to reduce the risk of chemicals

Our research is dedicated to the social processes and conflicting goals that characterize the way we deal with chemical risks and refers to social-ecological justice as a normative framework. We examine societal perception, promote the transfer of knowledge to raise awareness and develop ways to involve society more closely in political decision-making processes.

Our research topics include the sustainable use of plastics, the risks of microplastics and PFAS and strategies for reducing pharmaceutical substances in water.

    ISOE Citizens’ University: It’s slipping away! Risks posed by PFAS to the environment

    The so-called ‘forever chemicals’ (PFAS) are highly versatile but pose significant risks to both human health and the environment. On June 23, 2025, ISOE will dedicate its next Citizens’ University to exploring the dangers associated with this problematic group of substances.

    The significance of socio-ecological tipping points for the savannahs of Namibia

    Climate change is exacerbating water scarcity, especially in the arid regions of the world. Namibia, with its savannah landscapes, is particularly affected. These ecosystems are among the driest regions in the world and are already threatened by climate change and an increasing pressure from land use. Thus, conventional forms of livestock farming are leading to a deterioration of rangelands which is why the savannah ecosystem is approaching tipping points. Together with partners from Germany and Namibia, a current research project at ISOE has been investigating how climatic, ecological and societal factors are accelerating land degradation in arid regions.

    Strategic communication on the risks of perpetual chemicals

    PFAS – these four letters stand for the controversial group of substances known as perfluorinated and polyfluorinated alkyl substances. As they are water-, grease- and dirt-repellent, these chemicals are used in numerous everyday products. However, it is precisely because of their properties that PFAS are barely degradable and the “perpetual chemicals” have already been detected in human blood and as well as in breast milk. The EU is therefore looking into restricting PFAS. However, the risks associated with PFAS are presented and assessed in differing ways. Against this background, a new ISOE research project is investigating how various organizations communicate the risks of PFAS.

    New technology from Hesse can protect against the spread of tropical diseases

    The warm season in Europe marks the beginning of the high season for mosquitoes. While they and their larvae serve as prey for many animals and thus play an important role in the ecosystem, humans find the small bloodsuckers rather annoying. Meanwhile, they can also become dangerous to us: mosquitoes from tropical and Asian regions are increasingly appearing in Central Europe. They can transmit the Zika or West Nile viruses, which trigger dangerous fever diseases. A team of Hessian Scientists including ISOE-researcher Marion Mehring is showing how the further spread of these mosquito species can be prevented in a targeted and environmentally friendly way.

    Anthology: Living in the Plastic Age

    Since their invention in the 19th century, plastics have revolutionized almost all areas of daily life due to their versatile properties. However, in the “plastic age”, mass consumption poses far-reaching problems for society and nature. For sustainable solutions, plastics and their risks require a comprehensive understanding, with a holistic view of the path from production to consumption and disposal. Johanna Kramm and Carolin Völker of ISOE – Institute for Social-Ecological Research therefore look at the complex problems involved in dealing with plastics and possible solutions from various disciplinary perspectives in the anthology they edited under the title “Living in the Plastic Age.”

    “SCIP plastics”: Reducing plastic waste in Bangladesh

    Every day, around 480 tons of waste end up on the streets of Khulna, the largest city in the densely populated Ganges Delta. This includes vast quantities of plastic that is washed into the oceans via Bangladesh’s neighboring waters. Without countermeasures, marine pollution will continue to increase. The aim of the SCIP plastics joint project is therefore to establish a sustainable waste system in Khulna in order to reduce plastic waste in the long term and protect the aquatic habitat. The project that is funded by the German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) with around four million euros will be implemented by Bauhaus University Weimar in cooperation with ISOE – Institute for Social-Ecological Research until 2024.
