Greenhouse experiments were carried out aiming to characterize-morphologically and biochemically-resistant and susceptible plants of C. sumatrensis. Two experiments were carried out to evaluate the behavior of morphological variables such as leaf area, height, and dry biomass weight, without application of paraquat (1,1'-dimethyl-4,4'-bipyridinium dichloride). Other experiments were conducted with two rates of paraquat application (0 and 800 g a.i ha-1); physiological variables were assessed at 2, 4, and 24 h after application (HAA), and plants were collected at 4 HAA for biochemical analyses of antioxidant enzymes and cell membrane peroxidation level. Without herbicide application, paraquat-resistant populations had higher dry biomass, leaf area, liquid photosynthetic rate, carboxylation efficiency, and stomatal conductance. The recovery of the photosynthetic apparatus by resistant plants after paraquat application is rapid (16 HAA) and, in general, presents physiological improvements in terms of photosynthetic rate and carboxylation efficiency. After paraquat treatment, the antioxidant system enzymes of resistant plants showed increased activity and decreased membrane peroxidation, indicating that these enzymes play an important role in the resistance mechanism of these plants.

通过温室试验对苏门答腊树的形态特征和生化抗性及易感植株进行了研究。在不施用百草枯(1,1′-二甲基-4,4′-二氯化联吡啶)的情况下,进行了两个实验,以评估叶面积、高度和干生物量等形态变量的行为。其他试验采用两种百草枯施用量(每公顷0克和800克)进行;在施用后2、4和24 h评估生理变量,并在4 h收集植株进行抗氧化酶和细胞膜过氧化水平的生化分析。在不施用除草剂的情况下,抗百草枯群体的干生物量、叶面积、液体光合速率、羧化效率和气孔导度均较高。施用百草枯后,抗性植物的光合机构恢复迅速(16 HAA),总体上在光合速率和羧化效率方面表现出生理改善。百草枯处理后,抗性植株抗氧化系统酶活性升高,膜过氧化作用降低,表明这些酶在抗性机制中发挥重要作用。

The copper ion was detected rapidly by a novel sensing membrane in this paper for its damage to health and the environment. CdSe/ZnS QDs modified polyethersulfone membrane (QDs@PESM) was made by phase-inversion method using a membrane separation technique and quantum dots (QDs). When the sample passed through the membrane, the copper ions in the sample caused the membrane's fluorescence to be quenched. The fluorescence quenching value of the membrane is used to calculate the concentration of copper ions. With R2= 0.9964, Cu2+could be quantitatively detected over a wide concentration range (10-1000 μg/L). The method's LOD and LOQ were 4.27 and 14.23 μg/L, respectively. When the CdSe/ZnS QDs@PESM was used to analyze Cu2+ in various real drinks, including well water, baijiu, orange juice, beer, and milk, the recovery ranged from 79.1 to 123.9%, indicating that the CdSe/ZnS QDs@PESM can be used as a rapid, simple and reliable method to determine Cu2+ in various matrices.

由于铜离子对人体健康和环境的危害,本文采用一种新型传感膜对其进行了快速检测。利用膜分离技术和量子点(QDs),采用相变法制备了CdSe/ZnS量子点改性聚醚砜膜(QDs@PESM)。当样品通过膜时,样品中的铜离子使膜的荧光被猝灭。膜的荧光猝灭值用于计算铜离子的浓度。R2= 0.9964,可在10 ~ 1000 μg/L的浓度范围内定量检测Cu2+。该方法的定量限和定量限分别为4.27和14.23 μg/L。利用CdSe/ZnS QDs@PESM对井水、白酒、橙汁、啤酒、牛奶等多种实际饮料中的Cu2+进行分析,回收率为79.1 ~ 123.9%,表明CdSe/ZnS QDs@PESM可作为一种快速、简便、可靠的测定各种基质中Cu2+的方法。

The present study assessed the removal of fenamiphos, imidacloprid, and oxamyl pesticides from water using algal Nannochloropsis oculata biomass. Several factors, such as algal biomass concentration, incubation time, and pesticide concentration, were studied for their impact on pesticide removal. Analysis and quantification of pesticides by rapid HPLC have been developed and validated. The optimum conditions were obtained at 15 min, 50 mg/L of pesticide concentration, and 4,500 mg/L of the algal biomass with 92.24% and 90.43% removal for fenamiphos and imidacloprid, respectively. While optimum parameters of 10 min incubation, 250 mg/L of pesticide concentration, and 2,750 mg/L of the algal biomass exhibited 67.34% removal for oxamyl. N. oculata, marine microalgae, successively removed different concentrations of the tested pesticides from water, and the algal biomass showed a potential reduction of pesticides in polluted water samples.

The aim of our study was to evaluate the use of Raman spectroscopy for pre-diagnostic estimation of weed response to bleaching herbicides. Model plants were Chenopodium album and Abutilon theophrasti treated with mesotrione (120 g a.i. ha-1). Raman single-point measurements were taken 1, 2, 3, and 7 days after herbicide application from different points on the leaves. Principal component analysis (PCA) was carried out on data normalized by the highest intensity band at 1522 cm-1 and using spectral region from 950 to 1650 cm-1 comprising mainly contributions of carotenoids. The carotenoids by intensive band at ∼1522 cm-1 and bands with lower intensity at ∼1155 and 1007 cm-1 in treated plants were confirmed. According to PC1 (the first principal component) and PC2 (the second principal component), the highest intensity bands responsible for treatment differentiation in C. album could be assigned to chlorophyll, lignin, and carotenes. According to PC1 in A. theophrasti leaves the treatment differences could be observed 7 days after mesotrione treatment and PC2 gave a clear separation between all control and treated leaf samples. Raman spectroscopy may be a good complement to invasive analytical methods, in assessing the plant abiotic stress induced by bleaching herbicides.

我们研究的目的是评估拉曼光谱在杂草对漂白除草剂反应的预诊断估计中的应用。模式植物为经甲氧三酮(120 g a.i. ha-1)处理的Chenopodium album和Abutilon theophrasti。在施用除草剂后1、2、3和7天,分别在叶片上的不同点进行拉曼单点测量。数据经1522 cm-1最高强度波段归一化,用950 ~ 1650 cm-1主要贡献类胡萝卜素的光谱区域进行主成分分析。在~ 1522 cm-1和~ 1155和1007 cm-1的较低强度波段,证实了处理植株的类胡萝卜素。根据PC1(第一主成分)和PC2(第二主成分)的谱带,绿皮草中叶绿素、木质素和胡萝卜素是负责处理分化的最高强度谱带。在美索三酮处理7 d后,茶牡荆叶片的PC1可以观察到处理差异,PC2在所有对照和处理叶片样品之间有明显的分离。拉曼光谱法可作为入侵分析方法的一个很好的补充,用于评估漂白除草剂引起的植物非生物胁迫。

This study was conducted to assess pesticide residues in 34 water and sediment samples taken from Kumkale Plain of Çanakkale-Turkey. Residue analyses were performed with the use of Quick-Easy-Cheap-Efficient-Rugged-Safe (QuEChERS)-liquid chromatography/tandem mass spectrometry (LC-MS/MS) procedure. For method verification, blank sediment and water samples were spiked at two limits of quantification (LOQ) levels of the pesticides. Overall recovery was 81.66% for sediment and 91.50% for water samples. In sediment samples, chlorpyrifos-M had the highest concentration, pyridaben was encountered in the majority of the samples (15 samples) and the highest number of pesticides (35) was seen in sample no. s13. In water samples, methoxyfenozide had the greatest concentration, metalaxyl was encountered in the highest number of samples (three samples) and the highest number of pesticide (8) was seen in sample no.w13. Sample no. s13 and w13 were taken from around the fountain basin. Pyraclostrobin and chlorantraniliprole residues exceeded the national limits set for water. In terms of hazard quotient (HQ), pesticides in sediment and waters were found to be safe. Despite the safe nature of pesticide on samples, greater attention has been paid on toxicity of the residues. It was concluded that authorities should put strict regulations on agrochemicals to reduce health risks of these chemicals.

本研究对Çanakkale-Turkey Kumkale平原34份水和沉积物样品的农药残留进行了评价。采用快速-简易-廉价-高效-坚固-安全(QuEChERS)-液相色谱/串联质谱(LC-MS/MS)方法进行残留分析。为了验证方法,空白沉积物和水样在农药的两个定量限(LOQ)水平下加标。沉积物和水样的总回收率分别为81.66%和91.50%。沉积物样品中,毒死蜱- m浓度最高,嘧螨灵含量最多(15份),农药残留量最多(35份)的样品为no. 5。向。水样中甲氧虫酰肼浓度最高,甲螨灵含量最多(3个),w13号样品中农药含量最多(8个)。样品没有。S13和w13取自喷泉盆周围。吡咯菌酯和氯虫腈的残留量超过了国家规定的水质标准。在危害系数(HQ)方面,沉积物和水体中的农药是安全的。尽管农药样品具有安全的性质,但农药残留的毒性问题越来越受到人们的关注。结论是,当局应该对农用化学品实行严格的规定,以减少这些化学品对健康的危害。

Micro-Multiple Reflection ATR (CMRATR) spectroscopy is a technique, using specialized equipment, which allows the enhanced sensitivity of multiple reflection ATR analysis of small amounts of liquids in a confined area hitherto reserved for single reflection equipment. This technique has demonstrated a high level of sensitivity, especially when used in conjunction with an evaporative technique. In this work, the technique will be used with a miniature CMRATR accessory, which has the added advantage of compatibility with the smallest current FTIR spectrometers, to analyze pesticides. The results presented here indicate that the CMRATR/evaporative technique can serve as both qualitative and quantitative support to the existing standard methodology.

This study aims to determine the optimal strategy and driving factors of the critical nodes of pesticide packaging waste recycling by constructing the recycling process of "village collection-town transport-county management." Counties, towns, and villages are the central nodes of collection, coordination, and communication in the recycling process. Their strategy selection and influencing factor analysis are related to the development of recycling. The county processing center, township transit center, and village recycling center were selected to construct a game model, and strategy and parameter assumptions were made to obtain the optimal strategy combination. The results showed that strict supervision, professional transportation and strict implementation are the best strategies for counties, towns and villages, respectively. Simulation analysis confirmed that factors such as cost, reward restricted the strategy selection of each subject. The higher the supervision, transport, and input costs, the lower the enthusiasm of counties, towns, and villages to participate in recycling, respectively.

Cresols and chlorophenols are chemical contaminants that are potentially toxic to humans and can be found in sewage sludge. These chemical contaminants can migrate into the sludge-soil-water system when sludge is used as a conditioner for agricultural soils. Thus, the objective of this study was to develop methodologies based on extraction with low-temperature partitioning (LTP) to determine cresols and chlorophenols in sewage sludge, soil, and water. The analysis was performed by gas chromatography coupled with mass spectrometry (GC-MS). The validated methods were applied to monitor cresols and chlorophenols in a column-leaching study of a sludge-soil-water system. Satisfactory results were achieved for selectivity, limit of quantification (LOQ), linearity, accuracy, and precision. In the column leaching study, only 2,4,6-trichlorophenol was quantified in sludge samples after 20 days of the experiment. None of the studied compounds were quantified in soil and leached water samples, due to the degradation promoted by the microorganisms present in the sewage sludge. Finally, validated methods were suitable for monitoring cresols and chlorophenols in the sludge-soil-water system.

甲酚和氯酚是对人类有潜在毒性的化学污染物,可以在污水污泥中找到。当污泥被用作农业土壤的调理剂时,这些化学污染物可以迁移到污泥-土壤-水系统中。因此,本研究的目的是开发基于低温分馏(LTP)提取的方法,以测定污水污泥、土壤和水中的甲酚和氯酚。采用气相色谱-质谱联用(GC-MS)分析。将验证的方法应用于污泥-土壤-水系统柱淋研究中甲酚和氯酚的监测。在选择性、定量限、线性、准确度和精密度方面均取得了满意的结果。在柱淋研究中,经过20天的试验,污泥样品中只有2,4,6-三氯酚被量化。由于污水污泥中存在的微生物促进了降解,土壤和浸出水样中的化合物都没有被量化。最后,验证的方法适用于污泥-土壤-水系统中甲酚和氯酚的监测。

This paper evaluates linear and nonlinear regression analysis to describe the empirical adsorption kinetics using pseudo-first-order (PFO) and pseudo-second-order (PSO) models. These models have been used to characterize the performance of adsorbents for environmental remediation and environmental modeling. Data were simulated using the PFO and PSO models with 1, 2, and 5% noise levels and fitted by nonlinear and linearized PFO and PSO equations. Nonlinear regression analysis provided rate constants and adsorption capacities with better accuracy than linearization. Besides the correlation coefficient, Chi-square and residual plot analysis helped choose the proper model to describe the adsorbent efficiency and validate the results. Both models and the NLR fitting were employed to reevaluate data obtained in our research group, including the adsorption of Hg(II) on thiol-modified vermiculite, glyphosate on soils rich in aluminum and iron oxides, phosphate on Fe(III) polyhydroxy cations modified montmorillonite, and paraquat on soil and vermiculite. While fitting the simulated data indicates an unequivocal and correct kinetic model, fitting the experimental data is not straightforward, suggesting mixed models rule the adsorption and that a large number of data points, especially at the initial steps of adsorption, provided by high throughput analysis, help to improve the kinetic modeling.

本文用拟一阶(PFO)和拟二阶(PSO)模型对描述经验吸附动力学的线性和非线性回归分析进行了评价。这些模型已被用于表征吸附剂的环境修复和环境建模的性能。采用噪声水平分别为1、2和5%的PFO和PSO模型对数据进行模拟,并采用非线性和线性化的PFO和PSO方程进行拟合。非线性回归分析提供了比线性化更好的速率常数和吸附量。除相关系数外,卡方分析和残差图分析有助于选择合适的模型来描述吸附剂效率并验证结果。我们使用模型和NLR拟合来重新评估我们研究小组获得的数据,包括汞(II)在硫醇改性蛭石上的吸附,草甘膦在富含铝和铁氧化物的土壤上的吸附,磷酸盐在铁(III)多羟基阳离子改性蒙脱土上的吸附,以及百草枯在土壤和蛭石上的吸附。虽然模拟数据的拟合表明了一个明确而正确的动力学模型,但拟合实验数据并不简单,这表明混合模型统治了吸附,并且高通量分析提供的大量数据点,特别是在吸附的初始步骤,有助于改进动力学模型。

Rosa roxburghii is a medicinal and edible plant, which is favored by consumers due to its rich vitamin C content. Residues and potential health risks of difenoconazole in the R. roxburghii ecosystem has aroused a concern considering its extensive use for controlling the powdery mildew of R. roxburghii. In this study, the residue of difenoconazole in R. roxburghii and soil was extracted by acetonitrile, purified by primary secondary amine and detected by liquid chromatography-tandem triple quadrupole mass spectrometry. The average recoveries in R. roxburghii and soil matrix varied from 82.59% to 99.63%, with relative standard deviations (RSD) of 1.14%-8.23%. The limit of quantification (LOQ) and detection (LOD) of difenoconazole in R. roxburghii and soil samples were 0.01 mg/kg. The dissipation of difenoconazole followed well the first-order kinetic, with a half-life of 3.99-5.57 d in R. roxburghii and 4.94-6.23 d in soil, respectively. And the terminal residues were <0.01-2.181 mg/kg and 0.014-2.406 mg/kg, respectively. The chronic and acute risk quotient values of difenoconazole were respectively 0.42% and 4.1%, which suggests that the risk was acceptable and safe to consumers. This study provides a reference for the safe and reasonable use of difenoconazole in R. roxburghii production.
