chronic toxicity of mercury (hgcl2) to the benthic midge chironomus riparius
نویسندگان
چکیده
in most aquatic ecosystems mercury accumulates more in the sediment than in water column. however, due to limited eco-toxicological data, it is difficult to predict the toxicity of these sediments. the present study evaluated the effects of inorganic mercury in spiked sediment on the survival, growth, and emergence of the midge chironomus riparius and compared the results to mercury concentrations reported in streams and rivers in africa. at 3.84 mg hg/kg dry sediment, mercury significantly reduced larval survival and midges emergence success in comparison to control sediment (p

Assessing the toxicity of dodecylbenzene sulfonate to the midge Chironomus riparius using body residues as the dose metric.
Dodecylbenzene sulfonate (DBS) is a component of linear alkylbenzene sulfonate (LAS), an anionic surfactant, mainly used in household detergents. Due to the large quantity of DBS in use, there is concern over adverse environmental effects. This work examined the toxicokinetics and toxicity of the 2-phenyl isomer of dodecylbenzene sulfonate in 4-d, 10-d, and partial life-cycle tests on the midge...
متن کاملBioconcentration and acute toxicity of polycyclic musks in two benthic organisms (Chironomus riparius and Lumbriculus variegatus).
In the current study, the bioconcentration behavior and acute toxicity of two polycyclic musks, Tonalide 7-acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronaphthalene (AHTN) and Galaxolide 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexa-methylcyclopenta[gamma]-2-benzopyran (HHCB), were studied in two benthic organisms. Polycyclic musks are frequently used fragrances, and they have been detected in diffe...
متن کاملLife cycle responses of the midge Chironomus riparius to polycyclic aromatic compound exposure.
During acute exposure, polycyclic aromatic compounds (PACs) act mainly by narcosis, but during chronic exposure the same compounds may exert sublethal life cycle effects. The aim of this study was therefore to evaluate the chronic effects of sediment spiked PACs on the emergence of the midge Chironomus riparius. Three isomer pairs were selected, and 28-day LC50 values and 50% emergence times (E...
متن کاملChronic toxicity of cadmium to Chironomus riparius (Diptera: Chironomidae) at different food levels.
The interacting effects of cadmium toxicity and food limitation on the midge, Chironomus riparius, were studied during chronic exposure in laboratory experiments. If the food was supplied ad libitum, both larval developmental time and mortality of the larvae were negatively affected by cadmium concentrations of 2.0-16.2 micrograms/L. The number of eggs deposited per female and the mean life spa...
متن کاملBioaccumulation of perfluoroalkyl compounds in midge (Chironomus riparius) larvae exposed to sediment.
Midge larvae (Chironomus riparius) were exposed to sediments from a deposition sampled at a site along the Rhône River (France) downstream of an industrial site releasing various perfluorinated chemicals. This sediment is characterized by high concentrations of perfluoroundecanoic acid (PFUnA) and perfluorotridecanoic acid (PFTrDA) and a low perfluorooctane sulfonate (PFOS) concentration. Conce...
متن کاملNano-sized Al2O3 reduces acute toxic effects of thiacloprid on the non-biting midge Chironomus riparius
This study focuses on interactions between nanoparticles and a pesticide. The aim was to investigate how nano-sized aluminum oxide (410 nm) can alter the toxic effects of thiacloprid, even if no sorption between particles and the insecticide takes place. Thus, our study investigated a rather unexplored interaction. We conducted our research with larvae of Chironomus riparius and used thiaclopri...
