“…Fig. 3 shows that TCP was relatively stable in the amber glass bottles in our experimental conditions, which is consistent with the findings that TCP is degraded in the environment via photolysis (Billing et al, 1984) and microbial degradation . Natural river water may contain microorganisms in the aqueous systems.…”

“…ClyYCI Cl~~OH TCP TCP is degraded in the environment via photolysis (aqueous half-life, 4 min in surface water at 40 oN latitude; Dilling et al 1984) and microbial degradation with an average soil half-life, 73 d at 25°C; Bidlack 1976}. In terrestrial ecosystems, chlorpyrifos dissipates rapidly from plant foliage, with half-lives of less than 1-7 d (Racke 1993).…”

“…GS-1 which was capable of degradating both of them (Liang et al 2011). However, it was also found that the photodegradation rate of TCP in aqueous solution was higher than that of chlorpyrifos at 313 nm, pH 7, 25 • C (Dilling et al 1984). Chlorpyrifos in solution decreased rapidly at the initial step of the degradation, considering that the removal rates of chlorpyrifos reached 50% in both planted and unplanted system after 1 day's culture.…”

Six wetland plants were investigated for their effect on the degradation characteristics of chlorpyrifos in nonsterile hydroponic system at constant temperature of 28 • C. The results showed that the removal rates of chlorpyrifos in the water of plant systems were 1.26-5.56% higher than that in the control without plants. Scirpus validus and Typha angustifolia were better than other hygrophytes in elimination of chlorpyrifos. The removal rates of the two systems were up to 88%. Plants of acaulescent group had an advantage over caulescent group in removing chlorpyrifos. Phytoaccumulation of chlorpyrifos was observed, and the order of chlorpyrifos concentration in different plant tissues was root > stem > leaf. It was also found that chlorpyrifos and its metabolite TCP decreased rapidly at the initial step of the experiment.
