High temperature can magnify the negative effects of phenanthrene on soil invertebrates

PhD defence, Tuesday, 31 May 2022. Wencai Dai.

Wencai Dai

During his PhD studies, Wencai Dai researched the interaction between effects of temperature and phenanthrene on soil invertebrates. Soil invertebrates are widely abundant in soil and play an important role in terrestrial ecosystems (e.g. organic matter decomposition and stimulation of microbial activity). Wencai Dai studied how extreme high temperature and/or phenanthrene negatively influence the phenotypic response of soil invertebrates and how the organism detoxifies phenanthrene under a heat shock.

The new research findings contribute to the understanding of toxicity of organic pollutants in nature and can further develop and improve risk assessment procedures taking account of realistic climatic conditions.

The PhD study was completed at the Department of Ecoscience, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
