Toxicological effects of pyrethroids on non-target aquatic insects

Effects of Seven Fungicides on Non-Target Aquatic Fungi

Aquatic risk assessments for fungicides are carried out without information on their toxicity to non-target aquatic fungi. This might cause an underestimation of the toxic effects to the aquatic fungal community. This study focuses on the question whether recently derived concentrations limits for fungicides considered to protect populations of primary producers and (in)vertebrates also do prot...

Effects of Cca Wood on Non-target Aquatic Biota

Studies are reviewed that demonstrate the leaching of Cu, Cr, and As from pressure-treated wood in aquatic environments. The metals leached out accumulate in sediments near the wood (particularly bulkheads, which have more surface area for leaching than dock pilings). The metals also accumulate in organisms, including epibiota that live directly on the wood and benthic organisms, which live in ...

Aquatic Insects: Hemimetabolous Insects – Plecoptera

Evaluating bioavailability of pyrethroids in aquatic systems

2. The dissolved-phase fraction (fdissolved) is a function of the characteristics and level of suspended solids and dissolved organic matter, which may be estimated from the following relationship, where [SS] is suspended solid content, [DOC] is DOC concentration, kd is partition coefficient between the dissolved phase and the suspended solids, and kDOC is the partition coefficient between the ...

Toxicological Evaluation of a New Lepidopteran Insecticide, Flubendiamide, in Non-Target Drosophila melanogaster Meigen (Diptera: Drosophilidae)

Background: Flubendiamide, comparatively a new pesticide designed to eradicate lepidopteran insect pests is known to have low risk to birds, mammals, fish, algae, honey bees, non-target arthropods, earthworms, soil macro- and micro-organisms, non-target plants as well as sewage treatment organisms; however, the risk assessment for aquatic invertebrates from metabolite could not be finalized wit...
