“…Rates of 2,4-D breakdown in flooded soils were markedly lower than those in non-flooded soils (Yoshida and Castro 1975;Sattar and Paasivirta 1980). Half-lives obtained by Kuwatsuka (1983) from various sources, were 30 to 40 d and 35 to 48 d in flooded soils under laboratory and field conditions, respectively.…”

“…The urine itself did not influence or overlap with the fluorescenceo ft he QDs, even thoughi tc ontained many biologicalc omponents, including nucleic acids, amino acids, and proteins.A long with PQ,t he other most-commonlyu sed herbicides in crop fields are 2,4-dichlorophenoxy acetic acid (2,4-D) and 2,4,5-trichlorophenoxy acetic acid( 2,4,5-T). [40,41] Therefore, it is also importantt oc heck the cross-reactive response of QDs toward 2,4-D and 2,4,5-Ti n dilute urine to avoid false positive results. Importantly,n either of these herbicides interfered with the detection of PQ (Figure 7b).…”

Red-light-emitting water-soluble semiconducting quantum dots (QDs) were synthesized by using a wide variety of commercially available thiol-type capping agents. QDs with a negatively charged nanosurface showed excellent selectivity for paraquat (PQ) at pH 7.4 over other commonly encountered pesticides/herbicides, including diquat (DQ). The presence of a 4,4'-bis-pyridinium unit in PQ enabled it to initiate long-range aggregation, thereby leading to the formation of nanostructures with excellent emission-quenching behavior. Precoated quartz plates were developed as a low-cost, portable sensor for the on-site detection of PQ in both natural water and human urine. Estimation of the PQ concentration was performed in different commercial formulations and the detection of PQ contamination in adulterated dairy product was also achieved with excellent sensitivity. Finally, we screened more than 50 different food items, including vegetables, fruits, cereals, and fodders, to construct a generalized marker for any residual PQ in such specimens.

“…A trial under laboratory conditions using a sandy clay soil containing trichloroethane demonstrated that continuous feed with inorganic nutrients and ethanol resulted in the selection of a methanogenic community capable of complete degradation of the contaminant [142]. Under field conditions, soil flooding has been shown to enhance degradation of a variety of compounds including DDT [143], 2,4-D [144] and the pesticide toxaphene [145]. The use of induced denitrifying conditions to enhance anaerobic degradation of halogenated organics has not been reported.…”

There is growing interest in the enhancement of microbial degradative activities as a means of bringing about the in situ cleanup of contaminated soils and ground water. The halogenated organic compounds are likely to be prime targets for such biotechnological processes because of their widespread utilisation and the biodegradability of many of the most commonly used compounds. The aim of this review is to consider the potential for microbiological cleanup of haloorganic‐contaminated sites. The technologies available involve the provision of suitable environmental conditions to facilitate maximum biodegradation rates either in the subsurface or in on‐site bioreactors. Methodologies include the supply of inorganic nutrients, the supply of oxygen gas, the addition of degradative microbial inocula and the introduction of co‐metabolic substrates. The potential efficiencies and limitations of the methods are critically discussed from a microbiological viewpoint with respect to substrate degradability and population responses to supplementation.
