Solubility Constraints on Aquatic Ecotoxicity Testing of Anionic Surfactants

Effect of Inorganic Cations on Bactericidal Activity of Anionic Surfactants.

Voss, J. G. (Procter & Gamble Co., Cincinnati, Ohio). Effect of inorganic cations on bactericidal activity of anionic surfactants. J. Bacteriol. 86:207-211. 1963.-The bactericidal effectiveness of two alkyl benzene sulfonates and of three other types of anionic surfactants against Staphylococcus aureus is increased in the presence of low concentrations of divalent cations, especially alkaline e...

Effects of Several Nonionic and Anionic Surfactants on Cucumber Protoplasts*

The effects of four nonionic and two anionic surfactants on cucumber protoplasts were examined by light and electron microscopy. Two nonionic surfactants, polyoxyethylene (POE) (n=10) nonylphenylether and POE (n=5) laurylether, caused swelling of protoplasts, followed by their bursting. The bursting gave more destructive effects preferentially on lamellar structures of chloroplasts than the swe...

Aquatic Ecotoxicity Testing of Nanoparticles—The Quest To Disclose Nanoparticle Effects

The number of products on the market containing engineered nanoparticles (ENPs) has increased significantly, and concerns have been raised regarding their ecotoxicological effects. Environmental safety assessments as well as relevant and reliable ecotoxicological data are required for the safe and sustainable use of ENPs. Although the number of publications on the ecotoxicological effects and u...
