Kinetics of simazine advanced oxidation in water
Journal of Environmental Science and Health, Part B, 2000Comparison of the effects and kinetics of UV photolysis and four advanced oxidation systems (ozone, ozone/hydrogen peroxide, ozone/UV radiation and UV radiation/hydrogen peroxide) for the removal of simazine from water has been investigated. At the conditions applied, the order of reactivity was ozone < ozone/hydrogen peroxide < UV radiation < ozone/UV

Simazine residue dynamics in small ponds
Bulletin of Environmental Contamination and Toxicology, 1976Herbicides are important aids in enhancing sport fishing, fish removal, and other recreational uses of lakes and ponds. Simazine, 2-chloro-4,6-bis(ethylamino)-s-triazine, has been tested for several years as an experimental aquatic herbicide and has been shown to be effective in controlling aquatic plants in many different situations (FLANAG~, 1960 ...

Atrazine and simazine degradation in Pennisetum rhizosphere
Chemosphere, 2004The ability of rhizosphere of four plant species to promote the degradation of charcoal-fixed atrazine and simazine in cement blocks of a long-term contaminated soil when mixed with a normal soil at 1:1 ratio was tested. Of the four selected plants viz., rye grass (Lolium perenne), tall fescue (Festuca arundinacae), Pennisetum (Pennisetum clandestinum)

Absorption and Translocation of Simazine in Parrotfeather
Weed Science, 1969Root applications of 2-chloro-4,6-bis(ethylamino)-s-triazine (simazine) at concentrations greater than 1.0 × 10-7M inhibited growth of parrotfeather (Myriophyllum brasilienseCamb.). Chromatographic analysis of exudate from detopped parrotfeather plants indicated that simazine was being tranlocated primarily as the intact molecule.

Veterinary and human toxicology, 1993
A case of simazine toxicosis in sheep was investigated. Affected animals exhibited generalized muscle tremors which progressed to mild tetany followed by collapse of the hind legs. Other signs included a short prancing gait with head tucked in a similar manner to that of a show pony.

Toxicity Endpoint Selections for a Simazine Risk Assessment
Birth Defects Research Part B: Developmental and Reproductive Toxicology, 2014BACKGROUNDCalifornia uses simazine at one of the highest levels for states in the United States (approximately 2.5 million lbs 2006–2010). Simazine causes neuroendocrine disruption and mammary cancer in test animals. A risk assessment was prioritized by the California Department of Pesticide Regulation because of the nondietary concern for simazine ...

Influence of Soil Aging on Sorption and Bioavailability of Simazine
Journal of Agricultural and Food Chemistry, 2006Characterization of pesticide bioavailability, particularly in aged soils, is of continued interest because this information is necessary for environmental risk assessment. However, pesticide bioavailability in aged soils has been characterized by a variety of methods with limited success, due in part to methodological limitations.

Abbauprodukte von Simazin in Gramineen
Experientia, 1966Coix lacryma-jobi L., about 20 days old and grown on watercultures, were fed with14C-ring-labelled simazine. After freeze drying, the plant tissue was extracted with chloroform and 80% ethanol. The ethanol extractable activities were fractionated on a cation exchange column.

Procedures for Analysis of Atrazine and Simazine in Environmental Matrices
2009There is an ongoing need to monitor soil and trophic chain samples for residues of triazine herbicides, particularly atrazine and simazine, because these herbicides are among the most used members of their class, are toxic, can be persistent, and are widely distributed in the environment.
