Chironomus riparius exposure to field-collected contaminated sediments: From subcellular effect to whole-organism response

The toxicity of three field-collected sediments differentially contaminated with pesticides, heavy metals, phtalates and polycyclic aromatic hydrocarbons (PAHs), was assessed in Chironomus riparius. For this purpose, C. riparius larvae were exposed throughout their entire life cycle to sediments col...

For this purpose, C. riparius larvae were exposed throughout their entire life cycle to sediments collected in three sites along the Saulx river in France, and the toxic effects were measured at different levels of biological organization: from the molecular (lipidomic analysis and transcriptional variations) to the whole organism response (respiration rate, shape markers and emergence rate).
