Mercury bioavailability was assessed by exposing the dipteran Chironomus riparius for whole life cycle to legacy-contaminated fluvial sediments (0.038–0.285 mg Hg kg−1 d.w.) and analyzing tissue concentrations in larvae at different exposure times (7, 11, 16 days) adults. In same experiment, diffusive gradients thin-film passive samplers (DGTs), both piston- probe-shaped, were co-deployed retri...

As there is still little knowledge of interactions between microplastics (MP) and hydrophilic compounds, we propose ways the toxicity pesticides can be modulated by MP, when sorption excluded. Larvae Chironomus riparius were exposed to thiacloprid (TH, 1 µg/L) polystyrene microplastic particles (PS; <50 µm; 150,000 1,000,000 particles/L) for 96 h, solely or in co-exposure. Burrowing behavior...

Abstract Sinhuber et al. (Sci Rep 11:3773, 2021) formulated an equation of state for laboratory swarms the non-biting midge Chironomus riparius that holds true when are driven through thermodynamic cycles by application external perturbations. The findings significant because they demonstrate surprising efficacy classical equilibrium thermodynamics quantitatively characterizing and predicting c...

A role for the rectum in the ionoregulatory homeostasis of larval Chironomus riparius was revealed by rearing animals in different saline environments and examining: (1) the spatial distribution and activity of keystone ionomotive enzymes Na(+)-K(+)-ATPase (NKA) and V-type H(+)-ATPase (VA) in the alimentary canal, and (2) rectal K(+) transport with the scanning ion-selective electrode technique...
