Acute toxicity of waterborne Cd, Cu, Pb, Ni, and Zn to first-instar Chironomus riparius larvae.
The acute toxicities of waterborne Cd, Cu, Pb, Ni, and Zn were determined in the first-instar larvae (generally considered to be the most sensitive) of Chironomus riparius, under standardized conditions. Toxicity tests were conducted in soft water (hardness, 8 mg/L as CaCO(3) equivalents) in the absence of food and were limited to 24 h to avoid control mortality associated with food deprivation...
متن کاملToxicity of fullerene (C60) to sediment-dwelling invertebrate Chironomus riparius larvae.
An environmentally realistic method to test fullerene (C(60) ) toxicity to the benthic organism Chironomus riparius was created by allowing suspended fullerenes to settle down, making a layer on top of the sediment. To test the hypothesis that higher food concentrations will reduce toxic responses, two food concentrations were tested (0.5 and 0.8% Urtica sp.) in sediment containing fullerene ma...
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 کاملA Determination of Metallothionein in Larvae of Freshwater Midges (Chironomus riparius) Using Brdicka Reaction
Among wide spectrum of biomolecules induced by various stress factors low molecular mass protein called metallothionein (MT) is suitable for assessment of the heavy metal environmental pollution. The aim of this work was to determine the metallothionein and total thiols content in larvae of freshwater midges (Chironomus riparius) sampled from laboratory exposure to cadmium(II) ions and from fie...
متن کاملپرورش انبوه لاروهای (Chironomus riparius (Dip.: Chironomidae
لاروهای آبزی پشه‌ی Chironomus riparius Meigen یکی از منابع غذایی غنی در پرورش ماهیان می‌باشد. کمیت و کیفیت ماده‌ی غذایی که در پرورش این لاروها استفاده می‌شود، بر رشد و نمو دوره‌ی لاروی این پشه تأثیر‌گذار است. این مطالعه شامل بررسی اثر جیره‌های غذایی مختلف (کود مرغی، پودر سویا و سبوس برنج) با مقادیر وزنی متفاوت (1، 3 و 5 گرم) بر رشد و نمو لاروها، تعیین زمان مناسب برداشت لاروها در دماهای مختلف (...
