Abstract
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.

Li Y, Yan H, Liu Q, Li X, Ge J, Yu X. Accumulation and transport patterns of six phthalic acid esters (PAEs) in two leafy vegetables under hydroponic conditions. CHEMOSPHERE 2020; 249:126457. [PMID: 32220682 DOI: 10.1016/j.chemosphere.2020.126457] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 02/26/2020] [Accepted: 03/07/2020] [Indexed: 06/10/2023]
Abstract
In this study, we investigated the accumulation and transport patterns of six phthalic acid esters (PAEs) in two leafy vegetables under hydroponic conditions. The tested PAEs included dibutyl phthalate (DBP), diethyl phthalate (DEP), diallyl phthalate (DAP), diisobutyl phthalate (DIBP), dimethyl phthalate (DMP) and benzyl butyl phthalate (BBP), and the tested vegetables included Gaogengbai and Ziyoucai. The results revealed that the six PAEs were taken up by vegetables from the solution, although their accumulation and distribution varied among PAEs. The ability of concentrating PAEs into the roots followed the order of BBP > DBP > DIBP > DAP > DEP > DMP, whereas the ability of concentrating PAEs in plant shoots had the opposite order. By analysing the fractionation of the six PAEs in vegetable roots, DMP had the largest proportion in terms of apoplastic movement, while BBP had the largest proportion in terms of symplastic movement. Correlation analyses revealed that the differences among the accumulation and distribution behaviours of the six PAEs in plant tissues were not only related to their physicochemical parameters, such as alkyl chain length and the octanol/water partition coefficient (logKow), but also related to the proportion of apoplastic and symplastic movement in the plant roots. In addition, PAEs were more readily accumulated in the Gaogengbai roots than in the Ziyoucai roots; however, the opposite trend was observed for the shoots.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2014; 21:13909-13928.

Abstract
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.

Redshaw CH, Wootton VG, Rowland SJ. Uptake of the pharmaceutical Fluoxetine Hydrochloride from growth medium by Brassicaceae. PHYTOCHEMISTRY 2008; 69:2510-2516.

Abstract
Since the European Union banned disposal of sewage sludge (SS) at sea in 1998 the application rate of SS to land has risen significantly. Land application is thus possibly an important transport route for SS-associated organic chemicals, including pharmaceuticals, to soils and perhaps also to plants. The potential for the selective serotonin re-uptake inhibitor, Fluoxetine HCl, to undergo uptake into Brassicaceae tissues was therefore investigated in a tissue culture study under laboratory conditions for 12 weeks. From growth medium containing 280 ng Fluoxetine HCl mL(-1), translocation into Brassica oleracea var. botrytis (cauliflower) stems (5% mean uptake of applied burden; 0.49 microg g wet weight(-1)) and leaves (3% mean uptake; 0.26 microg g wet weight(-1)) was confirmed, but no evidence of uptake into the curd was found; other possible explanations of the observations are also discussed. Although the data for individual plants were highly variable, as was the recovery of spiked internal standard (deuterated Fluoxetine HCl), the results nonetheless suggest uptake of Fluoxetine may indeed be a potential transport route to plants. A similar study of uptake from soils rather than from an artificial medium should now be undertaken, with greater numbers of replicates and improved analytical methods. Such studies have already demonstrated uptake of some antibiotics from manured soils by a variety of plants including Brassicaceae, suggesting that the uptake mechanisms may be more general.
