“…Zebrowski et al found that the systemicity of xenobiotics was related to the physical and chemical properties of the agent, the growth period of plants, or other conditions. 25 In addition, the concentrations of the two treatment groups were similar, and thus there was no significant difference between the two results. The systemicity of pesticides mainly depended on their physical and chemical properties.…”

“…The balance between uptake and metabolism may provide an explanation for this phenomenon. 24 The transmission of pesticides in plants mainly depends on transpiration flow, 25 and the content of triflumezopyrim in the third leaf was higher than that in the first or second leaf (Figure 2) within 72 h, which means that triflumezopyrim had acropetal direction in rice.…”

A new type of mesoionic insecticide triflumezopyrim is mainly used to control rice planthoppers, leafhoppers, etc. In order to study the uptake and translocation characteristics of this new insecticide in rice (Oryza sativa), a method for the detection of triflumezopyrim in rice, soil, and water was established using liquid–liquid extraction and QuEChERS sample pretreatment combined with liquid chromatography–triple quadrupole tandem mass spectrometry. The distribution of triflumezopyrim in rice was investigated after hydroponic treatment and foliar treatment at the concentrations of 2.5 and 5 mg·L–1 within the ranges of 24, 48, and 72 h. The results showed that triflumezopyrim could be absorbed by roots and form a systematic distribution in rice by hydroponic treatment; meanwhile, it could also be absorbed by leaves and transported to the bottom leaves under foliar treatment, but no triflumezopyrim was detected in the roots. Thus, triflumezopyrim exhibited high acropetal translocation within the rice plant. This study provides an important scientific basis for the development of an application strategy of triflumezopyrim to control planthoppers and leafhoppers as well as for the residue detection method and safety evaluation.

“…Reviews exist on general biological treatment of indoor air which include active biofiltration, but also deals to some extent with potted plants (Guieysse et al 2008;Soreanu et al 2013). In addition, there are several reviews on bioremediation and phytoremediation which focus on remediation of soils (Arthur et al 2005;Juwarkar et al 2010;McGuinness and Dowling 2009;Salt et al 1998), as well as reviews of modelling on xenobiotic accumulation in edible plants (Collins and Finnegan 2010;Trapp 2004;Zebrowski et al 2004). Recently, a review has been published dealing with deposition of atmospheric PAHs in plants (Desalme et al 2013).…”

Volatile organic compounds (VOCs) are found in indoor air, and many of these can affect human health (e.g. formaldehyde and benzene are carcinogenic). Plants affect the levels of VOCs in indoor environments, thus they represent a potential green solution for improving indoor air quality that at the same time can improve human health. This article reviews scientific studies of plants' ability to remove VOCs from indoor air. The focus of the review is on pathways of VOC removal by the plants and factors affecting the efficiency and rate of VOC removal by plants. Laboratory based studies indicate that plant induced removal of VOCs is a combination of direct (e.g. absorption) and indirect (e.g. biotransformation by microorganisms) mechanisms. They also demonstrate that plants' rate of reducing the level of VOCs is influenced by a number of factors such as plant species, light intensity and VOC concentration. For instance, an increase in light intensity has in some studies been shown to lead to an increase in removal of a pollutant. Studies conducted in real-life settings such as offices and homes are few and show mixed results.

“…In the study of MBOA translocation, there was evidence of behavior usually found in the dynamics of absorption of xenobiotics by plants [28]. There is an increase in concentration to relatively constant levels in the root and a gradually increasing concentration in the shoot, although this behavior may vary depending on the species studied and the compound being absorbed.…”

“…The allelochemical concentrations measured in the root and the shoot represent a time-dependent phytotoxic effect. It is generally considered that the maximum rates of absorption and detoxification are measured during the early stages of development of the plant [28]. Given this fact, the values of the root/shoot concentration ratio for different weeds for a treatment time of one day (Figure 4, bar graph) were compared.…”

Absorption and Elimination of the Allelochemical MBOA by Weeds during Seedling Growth

6-Methoxy-2-benzoxazolinone (MBOA) is an allelochemical that is found in Poaceae and is generally associated with monocotyledon species. This compound is formed from the glycosylated form of 2,4-dihydroxy-(2H)-1,4-benzoxazin-3(4H)-one (Gly-DIMBOA) by a two-stage degradation process. The MBOA detoxification capacity of two weed species, namely Echinochloa crus-galli and Lolium rigidum, and a resistant biotype of Lolium rigidum (SLR31) was studied both qualitatively and quantitatively. The product of metabolism is similar for both weed species. This finding indicates that these weeds probably metabolize xenobiotics by an identical route, since the product detected was the same in both cases. Kinetic studies on the absorption and translocation to the shoot showed differences in these processes depending on the species. The analysis of treated plants, which were subsequently transplanted to a growth medium without xenobiotic compound, showed that the weeds studied are capable of transmitting the previously absorbed compound to the medium by root exudation. The results show that this process is another defense mechanism of plants facing external threats.
