The toxicity of surfactants to marine organisms and their concentration in them depends upon their tendency to adsorb onto them and their ability to penetrate their cell membranes (Rosen, 1999). The parameter AG0ad/a, where AG°a(j is the standard free energy of adsorption of the surfactant at the aqueous solution-air interface (Chapter 2, Section IIIF) and am is the minimum cross-sectional area of the surfactant at that interface (Chapter 2, Section IIIB), was found to correlate well for several anionic and nonionic surfactants with rotifer toxicity. The same parameter was found to correlate well for a series of cationic surfactants with rotifer and green algae toxicity and, for a series of linear alkylbenzenesulfonates, with bioconcentration in fish (Rosen, 2001).

Environmental Considerations. The phosphate flame retardants, plasticizers, and functional fluids have come under intense environmental scmtiny. Results pubUshed to date on acute toxicity to aquatic algae, invertebrates, and fish indicate substantial differences between the various aryl phosphates (159—162). The EPA has summarized this data as well as the apparent need for additional testing (147). 

The effect of pyrogaHol on algae has also been studied (27). Acute toxicity data include oral LD q (rat) = 789 mg/kg, intraperitoneal LD3Q (mouse) = 400 mg/kg, and oral LD q (rabbit) = 1600 mg/kg (28). 

Public concern about the abundance of algae, and of the toxic cyanobacteria in particular, was raised by events in the UK in the summer of 1989 which involved the deaths of dogs and sheep at Rutland Water, Leicestershire, and the acute...

A slight toxic effect ( toxic defined as negative effects on health, growth, and reproduction) of the treated receiving water on the green alga Spiropyra species as a typical representative of the P-mesosaprobic zone was observed, when the test unit was subjected to the impact of 40 ppm secondary alkanesulfonates.
