“…2) leading to the rapid degradation of carbofuran in rhizosphere soils. Similar findings were reported previously by many authors (Singh et al 2004;Sun et al 2004;Yu et al 2003) in which the degradation of pesticides was improved in rhizosphere soil of various plants. Degradation of aldicarb and oxime, carbamate insecticides, in the rhizosphere soil of corn, mung bean and cowpea was found to be more rapid than in unplanted sterile and non-sterile soil (Sun et al 2004).…”

Two times shorter t 1/2 of butachlor was observed in rhizosphere soil in comparison to in non-planted soil indicating the enhancement of butachlor degradation by wheat rhizosphere soil (Yu et al 2003).…”

“…This might due to carbon containing compounds exudated from plant root such as sugars, carbohydrate, alcohol and amino acids, which could stimulate the microbial activities and increase number of rhizosphere microorganisms (Schnoor et al 1995;Stottmeister et al 2003). Published studies reported the degradation/removal of pesticides (Singh et al 2004;Yu et al 2003;Sun et al 2004), others organic hydrocarbons (Biryukova et al 2007;Chaudhry et al 2005;Nakamura et al 2004;Jordahl et al 1997), and heavy metals (Gaur and Adholeya 2004) by rhizosphere remediation. Their results also evidenced the enhancement of the contaminant removal in the rhizosphere zone as compared to in bulk soil.…”

Rhizosphere soil contains important sources of nutrients for microorganisms resulting in high number of microorganisms capable of degrading various types of chemicals in the soil. Thus, this study investigated a carbofuran dissipation in rhizosphere soils of 6 weeds namely, umbrella sedge (Cyperus iria L.), fuzzy flatsedge (C. pilosus V.), small flower umbrella plant (C. difformis L.), tall-fringe-rush hoorah grass (Fimbristylis miliacea V.), cover fern (Marsilea crenata P.), and water primrose (Jussiaea linifolia V.). Rhizosphere soil of fuzzy flatsedge showed the shortest half-life (t 1/2 ) of carbofuran (15 days) among other soils. So, it was selected to be used in the bioaugmentation experiment using carbofuran degrader namely Burkholderia cepacia, PCL3, as inoculum in order to examine whether they would improve carbofuran degradation in soil. The results showed that the addition of PCL3 into rhizosphere soil did not improve carbofuran degradation suggesting that microorganisms in rhizosphere soil might be capable enough to remove carbofuran from soil. The number of carbofuran degraders in the rhizosphere soils was greater than in bulk soil 10-100 times which might be responsible to a rapid degradation of carbofuran in rhizosphere soils without the addition of PCL3. The ability of PCL3 to degrade carbofuran was evident in bulk soil (t 1/2 of 12 days) and autoclaved soils (t 1/2 13-14 days) when compared to soils without an inoculation (t 1/2 of 58 days) indicated that the addition of a degrader was useful in improving carbofuran degradation in soil.

“…It was reported that the root density of turf grass grown in the loamy sand was significantly higher than that in the sandy loam soil [11]. The degradation of test chemicals would be higher in the loamy sand soil because of enhanced rhizospheric activities induced by the higher root density [28][29][30].…”

Abstract-Emerging pollutants inherent in reclaimed municipal wastewater, including endocrine-disrupting compounds (EDCs) and pharmaceutical and personal care products (PPCPs), often have cast uncertainties on the safety of water reuse. We examined the fate and transport behavior of several PPCP and EDC compounds through observations made at experimental turf fields irrigated with naproxen, clofibric acid, diclofenac sodium, ibuprofen, estrone, 4-tert-octylphenol, bisphenol A, 4-n-nonylphenol, and triclosan latent irrigation water. The potential of the compounds to contaminate underlying groundwater was assessed using three screening protocols that employed the attributes of soils, chemicals, and water fluxes as the estimators. No compound was detected in the leachate draining through the 89-cm profile of a loamy sand soil and a sandy loam soil turf grass field during four months of irrigation according to operations typical of golf courses in southern California (USA). Ibuprofen, naproxen, triclosan, bisphenol A, clofibric acid, and estrone were detected in the surface to 30-cm soil profiles. Higher irrigation rate and coarser textural soil enhanced the downward movement of chemicals in both soils. The pollution risk screenings identified the same six compounds as having the potential to contaminate groundwater, and under conditions of turf grass irrigation, clofibric acid and ibuprofen would be most prone to cause the pollution.

“…Both these phytostimulation or rhizodegradation processes are enhanced by large and dense root systems, which consequently have higher levels of degrading enzymes [28], and, hence, these are favorable characteristics in plants used for phytoremediation. Classes of organic compounds that are more rapidly degraded in the rhizosphere than in bulk soil include PAHs, total petroleum hydrocarbons, chlorinated pesticides as well as other chlorinated compounds like PCBs, explosives such as TNT and RDX, organophosphate insecticides, and surfactants [28,102,103].…”
