| Abstract |
Plastic pollution through small particles, so-called microplastics, is acknowledged as an environmental problem of global dimension by both politicians, and the public. An increasing number of environmental studies investigate the exposure and effects of microplastics. Although there are many open questions, current scientific evidence does not confirm a high risk for the environment. At the same time, the issue receives great public attention, which in turn motivates various political and policy actions. So far, little research has examined the underlying social dimensions, i.e., the factors explaining individual risk perception of microplastics. This paper studies the perception of risks associated with microplastics concerning the environment and human health using data from a representative online survey conducted in Germany (n = 1027). We particularly examine the role of socio-demographics, individual awareness, knowledge factors, and the media’s influence on risk perception. Our results show that a majority of the respondents rates the risks through microplastics very high for both the environment and human health. Regression analyses demonstrate that environmental awareness and knowledge of media narratives are the strongest predictors for this risk perception. Our study illustrates the incongruence between scientific knowledge, media framing, and the public opinion concerning the risk posed by microplastics. |
