“…The amount of simazine used for aquatic plant con trol can vary between 0.5 and 10.0 ppm depending on type of plant, mineral content of the water, and temper ature (2). Concentrations of 1.0 and 3.0 ppm were chosen for this study as average concentrations used in actual field applications.…”

The uptake and release of 2-chloro-4,6-bis(ethylamino)-s-triazine (simazine) by green sunfish (Lepomis cyanellus Raf.) were measured during a 3-week exposure to either non-labeled or symmetrically ring-labeled 14C-simazine. Exposure was by feeding (3 and 10 mg/kg body wt) or bath (1 and 3 ppm). To determine the retention of simazine, treated fish remaining after exposure and sampling were placed in fresh water for 4 weeks. This water was changed weekly. Fish in the bath absorb simazine in amounts directly proportional to the concentration in the water: i.e., 0.95 and 2.29 ppm total residue after 3 weeks exposure to 1.0 and 3.0 ppm, respectively. Little or no simazine was found in feed-exposed fish 72 hr after feeding. Almost all of the residue was in the viscera. No simazine residue was detected in fish from the water bath exposure after they had been in fresh water 7 days.

“…The effectiveness of triazines has been studied in detail in the U.S.A. by Walker (1964bWalker ( , 1965a) and by Sutton, Errard & Bingham (1966). Ametryne has been found promising [331a] and especially been studied as an algicide [242,284] and also in India [252].…”

“…Little data are available on the eflects of herbicides on cell membrane permeability in aquatics. The following herbicides have been used to control aquatic weeds: simazine (Ellis et al, 1976;Johannes et al, 1973;Walker, 1964) dalapon (Holland, 1977;Brooker, 1976;Mueller &Lembi, 1975/76), 2,-4-D (Holland, 1977;Chandra Singh & Narayana Roa, 1976;Brooker, 1976) and glyphosate (Barrett, 1976;Shibayama & Miyahara, 1977;Holland, 1977). These herbicides together with prometryne, linuron, dinoseb, amitrole, sodium azide and oxyfluorfen were used in this study.…”

Summary: Leakage of electrolytes was the criterion used to study the effects of several herbicides on cell membrane permeability in Lemna minor L. Dinoseb. sodium azide, linuron, prometryne and simazine were the most active in increasing cell membrane permeability, followed by oxyfluorfen, amitrole, and 2,4—D. Glyphosate and dalapon were the least active. In all cases, the longer the period elapsed after treatment (i.e. 96 h) the lower was the concentration needed to alter cell membrane permeability. Light was necessary for oxyfluorfen activity. With glyphosate, dalapon and oxyfluorfen, visible injury symptoms were noted after 48–96 h, but no further significant increase in cell membrane permeability occurred as a result.
