Sensitivity of an infaunal amphipod, Eohaustorius estuarius, to acute waterborne exposures of 4-nonylphenol: evidence of a toxic hangover.
Three independent trials were conducted using mortality and burial as endpoints. Amphipod mean lethal concentration to 50% (LC50) was 227 microg/L. One-hour burial as a sublethal endpoint increased the sensitivity of the toxicity test by 40%; however, most amphipods that survived exposure were able to recover within 24 to 48 h. This toxic hangover was dose-dependent.

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
Effects of emamectin benzoate combined with acetamiprid, eforia and hexaflumuron against Tuta absoluta (Lep.: Gelechiidae)
Tomato leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) is one of the most destructive pests of tomato in many parts of the world including Iran. The toxicity of emamectin benzoate alone and combined with acetamiprid, eforia (thiamethoxam + lambda-cyhalotrin) and hexaflumuron was evaluated against 2nd instar larvae of Tuta absoluta (Meyrick) under 25 ± 1 °C, the relative humidity of ...
متن کاملDetermination of emamectin benzoate in medicated fish feed.
A method was developed to quantitate emamectin benzoate in fish feed at levels between 5 and 15 ppm. The active ingredient is extracted from 20 g medicated feed into aqueous-methanolic solvent by overnight shaking. A solid-phase extraction procedure using a 2 g C18 cartridge is then used to concentrate the active residue and remove interfering matrix components. The extracted drug and internal ...
