“…Non-ionic surfactants are even more effective in increasing enzyme stability and positively improving efficacy of enzyme-substrate interactions (Eriksson et al, 2002). Moreover, many surfactants such as alcohol ethoxylates and alkylphenol ethoxylates that are biodegradable in the soil environment are safer as result of their rapid breakdown to less toxic, less persistent and less estrogenic compounds than alkyl polyphenol ethoxylates (ElSayed and Prasher, 2013).…”

“…Triazine herbicides constitute one of the largest groups of pesticides used throughout the world (Salman et al, 2012;Hamza et al, 2015). Triazinones, such as metribuzin (4-amino-6-tert-butyl-4,5-dihydro-3 methyltio-1,2,4-triazin-5-one) are used worldwide to control broadleaf weeds in crops such as potatoes, soybeans and other vegetable crops (El Sayed and Prasher, 2013). As a result of its widespread use, metribuzin paid more attention as it considered a potential environmental contaminant (Mehdizadeh, 2014).…”

Two different herbicides isoproturon and metribuzin were stored at zero °C for 7 days and under accelerated storage temperature at 54°C for 14 days to study degradation of active ingredient which determined by HPLC-DAD. Physical properties such as change of pH values, suspensibility, wet sieve test, pourability, spontaneity of dispersion and persistent foam test before and after storage were also studied according to FAO specification. Results showed that active ingredient of isoproturon formulation was slightly affected by accelerated storage temperature at 54°C and become conformity with FAO specification but metribuzin formulation was affected when stored after 10 days at 54°C while the degradation increasing by long time of storage. Physical properties of two herbicides formulations passed successfully through all storage periods at zero °C for 7 and at 54°C for 14 days except wet sieve test of metribuzin. On the other hand, the present two herbicides were evaluated using 1/20 of their LD 50 on some biochemical components of albino rats in initial time at 23±2°C and after 14 days from storage at 54°C. The results showed that the two herbicides in initial time caused high decreasing in content of total soluble protein with high increasing in levels of glucose, urea, creatinine, bilirubin, cholesterol and triglycerides. Also the activities of Aspartate aminotransferase (AST), Alanine Aminotransferase (ALT) and Alkaline phosphatase (ALP) were high relative to control. In case of two herbicides after storage 14 days at 54°C, the results showed slight decrease in content of total soluble protein, but the levels of serum glucose, urea, creatinine, bilirubin, cholesterol and triglycerides were low increase relative to health normal control. The results showed that activities of AST, ALT and ALP were the stimulated under the effect of the both herbicides compared with the normal. The biochemical harmful of the herbicides under storage at 54°C for 14 days was lower than those of effect initial time at 23±2°C were compare, the influences of metribuzin on the biochemical study it was more than that of isoproturon either in initial time at 23±2°C and after 14 days from storage at 54°C.

Effect of Triton X-100 on the wheat and lettuce growth and contaminant absorption

This study was set to study the effects of surfactants on crops using Triton X-100, one of widely used surfactants for various purposes including agricultural uses, as a target surfactant. The effects of Triton X-100 on the growth of wheat and lettuce were studied and the germination and shoot growth of wheat were not significantly affected by Triton X-100. With lettuce, the increasing Triton X-100 concentrations tend to negatively affect the growth, possibly due to the absorption of Triton X-100 by lettuce. The average lettuce fresh mass was reduced by 31% when Triton X-100 concentration increased from 0 to 240 mg L−1. This may mean that chemicals dissolved or mobilized by Triton X-100 can be absorbed by lettuce. The Cd mobilization was facilitated with Triton X-100, and the absorption of procymidone in soil by lettuce was greater when Triton X-100 was applied (i.e., 0.18 mg kg−1) than when water was applied (i.e., 0.15 mg kg−1), although they were statistically not different (p-value > 0.05). The average lettuce masses in the presence of residual procymidone in soil and Triton X-100 (16 g) were lower than that of the control soils (20 g), although they were statistically not different (p-value > 0.05). The results suggest that surfactants contained in pesticide formulations can potentially affect crop growth and absorption of other contaminants. Therefore, the residual surfactants and active ingredients in pesticide formulations need to be properly managed to protect the environment and to produce crops free of contaminants.
