This work focused on the influence of initial concentration on toxicity and removal potential of chlorpyrifos by Scirpus tabernaemontani under laboratory greenhouse conditions. An increased sensitivity and reduced removal rate to chlorpyrifos were observed with increasing chlorpyrifos concentration. At initial concentrations of 0, 1 and 2 mg·L−1, the relative growth rates (RGRs) of S. tabernaemontani...
To investigate the effects of different concentrations of chlorpyrifos on soil ecological environment and on soil respiration, catalase, urease, and levansucrase activity, studied by laboratory simulation methods. The results showed that: different concentrations of chlorpyrifos on soil respiration has a significant activation effect only at the first day, and a positive correlation with the concentration;...
In order to increase the degradation efficiency of chlorpyrifos pesticides in soil, a organ phosphorous degrading condition was optimized for a compound microbial agent which composed of a high-performance microbial and unninghamella. Orthogonal design table was used to select soil moisture, pH, chlorpyrifos concentration and compound microbial agents inoculation amount as reference factors in potted...
A chlorpyrifos-degrading strain of Stenotrophomonas acidaminiphila, lux-β was chosen for research object, and the survival and chlorpyrifos-degrading activity of strain lux-β in the soil with different treatments have been investigated in this study, so as to provide technique support for monitoring the colonization and degrading activity of chlorpyrifos-degrading bacteria in natural environment....
In this study, the chlorpyrifos degradation differences of two degrading bacteria from two sources are measured and analyzed, one is X1, cultivated and isolated from the sludge of a city sewage treatment plant; the other comes from the long-term chlorpyrifos contaminated soil, named D. The results show that: the two degrading bacteria do not inhibit each other, degradation capacity of strain D is...
The joint acute toxicity of chlorpyrifos and bata-cypermethrin on freshwater protozoan community was examined with the polyurethane foam unit method. Forty-eight-hour LC50 values were 8.72 mg/L for chlorpyrifos and 1.92mg/L for bata-cypermethrin in individual acute toxicity test. Our data indicated that the extent of toxic interactions of two insecticides showed synergism in 48h exposure. Additive...
To develop a rapid and sensitive analytical methods for the quantitative determination of trace organophosphorus pesticides (OPPs) in soil. The target analytes, seven OPPs including dichlorvos, dimethoate, monocrotophos, methyl parathion, parathion, malathion and chlorpyrifos were extracted with the solution of acetone/dichloromethane (1:1, v/v) using accelerated solvent extraction (ASE) and then...
