“The toxic substance has killed all ducks”: framing of chemical risks related to the 2021 summer flood in German news media

Abstract

Background

The public understanding of environmental issues, such as chemical pollution due to flooding, is reflected and shaped by media representations and how these issues are framed. This study aims to identify how local, regional, and national German newspapers pick up and frame the issue of chemical pollution and related environmental and health risks regarding the 2021 summer flood using content analysis.

Results

The analysis shows that chemical pollution is rarely addressed compared to other flood-related topics. We identified 189 newspaper articles published in the months following the flood, which specifically mention chemical emissions. Of these articles, 50 report only marginally on chemical pollution, while 36 focus on the factual description of chemical emissions without addressing the consequences of pollution. The remaining 103 articles address impacts of certain pollutants such as oil, pesticides, heavy metals, or dioxins. Using content analysis, we identified four narratives that were common in their broad storylines and used to create a problem frame: (i) Highlighting severe contamination of the environment with chemical pollutants causing serious environmental damage (31 articles), (ii) describing possible contamination but with uncertainty about the extent and consequences (39 articles), (iii) tending to give the all-clear and emphasizing that there is no severe long-term contamination (25 articles), and (iv) indicating continuous contamination that does not allow the all-clear to be given (8 articles).

Conclusions

The results suggest that flood-related chemical pollution does not receive much media attention. Where it does, coverage focuses primarily on the description of the “tangible parts” of pollution, and thus contamination by oil, depicted by both smell and oil streaks, is frequently addressed Articles indicating severe contamination suggest threats to human and environmental health as likely consequences. However, most articles only report the results of chemical monitoring in the contaminated regions, which are evaluated by experts. This contrasts with other topics of controversy related to the flood, such as climate change as a potential cause. In light of our study, we propose that media and science communication need to pay more attention to chemical pollution—in general and as a result of flood events.
