“…The aquatic environment is contaminated by various organic and inorganic substances like pesticides, pharmaceuticals, etc., originating from industrial, municipal, or agricultural activities (Yadav et al 2015;Jabali et al 2018). During the last few decades, pesticides are being used heavily in agriculture to ensure high crop yield.…”

The study evaluated removal efficiency of 43 pesticides from water by thin-film composite polyamide membrane indigenously prepared by interfacial polymerization of 1,3-phenylenediamine and 1,3,5 trimesoyl chloride coated on asymmetric polysulfone support. Membrane performance was evaluated by gas and liquid chromatography mass spectroscopy determination of multiple pesticides remaining in feed and permeated water following the application of pesticides each @ 0.02, 0.05, and 0.10 mg/L in de-ionized water. The membrane was most efficient in the rejection of persistent organochlorine insecticides, viz. endosulfans (100%), dichlorodiphenyltrichloroethane (95%), and hexachlorocyclohexane (92%). Out of 43 selected pesticides, 33 were removed by > 80%. Size exclusion mass transfer played a significant role for molecules to pass through the membrane as observed for endosulfan isomers, endosulfan sulphate, and difenoconazole with molecular weight > 400. Pesticide rejection was also related to hydrophobicity (Log P). Hydrophobic pesticides with log P > 4.5 were rejected by > 80%, while monocrotophos with less hydrophobicity (log P = − 0.22) exhibited poor rejection (38%). Water flux decreased with an increase in pesticide concentration. The process of pesticide filtration was optimized at 200 psi. The results indicated the potential of the membrane to remove pesticides from water.

“…The focus of this work was the optimization of the HS-SPME strategy, while a previously optimized GC-MS method was employed for the PAHs detection. Among the wide range of possibilities offered by the SPME coatings, polydimethylsiloxane (PDMS) was selected for this study due to its commercial availability and suitability to extract PAHs, as previously reported [ 33 , 34 , 35 ]. A preliminary evaluation of an HS-SPME-GC-MS method was performed to set the concentration levels to be spiked onto the sprout pool, in order to have an acceptable sensitivity for the subsequent optimization.…”

Solvent-Free Determination of Selected Polycyclic Aromatic Hydrocarbons in Plant Material Used for Food Supplements Preparation: Optimization of a Solid Phase Microextraction Method

et al. 2023

The exploitation of waste and by-products in various applications is becoming a cornerstone of the circular economy. A range of biomasses can be employed to produce food supplements. An example is a particular extract obtained from plant buds (rich in bioactive molecules), which can be easily retrieved from cities’ pruning. In order to safely use this material, its possible contamination by organic pollutants needs to be estimated. A green and simple method to detect priority polycyclic aromatic hydrocarbons (PAHs) in bud samples by head space solid phase microextraction coupled to GC-MS was developed. This strategy, optimized through experimental design and response surface methodology, requires a minimal sample pre-treatment and negligible solvent consumption. The final method was found to be accurate and sensitive for PAHs with mass up to 228 Da. For these analytes, satisfactory figures of merit were achieved, with detection limits in the range 1–4 ng g−1, good inter-day precision (relative standard deviation in the range 4–11%), and satisfactory accuracy (88–105%), along with specificity guaranteed by the selected ion monitoring detection. The method was applied to bud samples coming from differently polluted areas, thus helping in estimating the safety of their use for the production of food supplements.

“…The extraction time was shorter than that by SPME GC‐MS [44] and HS‐SPME GC‐FID [45], but longer than that by SPME GC‐MS [42, 43] and SPME GC‐MS [46]. The LODs were lower than that by the methods [42, 44, 45], but higher than that by HS‐SPME GC‐MS [43] and SPME GC‐MS [46]. In short, the current method has a relatively good performance in terms of sensitivity (the LOD ranged from 0.05 to 0.15 ng/mL), linear range (0.25–50 ng/mL), and extraction time (45 min).…”

“…The established method was compared with some relevant SPME methods in literatures [42–46] through the parameters of LODs, linear range and extraction time (Table 2). The linear response range for the analytes by the current method was wider than that by SPME‐GC‐MS methods [44, 46], but narrower than that by SPME GC‐MS [42], HS‐SPME GC‐MS [43], and HS‐SPME GC‐FID [45]. The extraction time was shorter than that by SPME GC‐MS [44] and HS‐SPME GC‐FID [45], but longer than that by SPME GC‐MS [42, 43] and SPME GC‐MS [46].…”

A novel hexagonal boron nitride modified reduced graphene oxide material was synthesized and used as the adsorbent for the solid‐phase microextraction of seven polycyclic aromatic hydrocarbons from water and soil samples prior to their detection by gas chromatography‐flame ionization detector. Under optimal conditions, the linear response range of the analytes for water sample is 0.25–50 ng/mL with the correlation coefficients (r) ranging between 0.9953 and 0.9996. The linear range for soil sample is 1.0–400 ng/g with r ranging from 0.9959 to 0.9999. On the basis of the signal‐to‐noise ratio of 3, the limits of detections for the analytes ranged from 0.05 to 0.15 ng/mL for water samples, and from 0.3 to 0.5 ng/g for soil samples. The relative recoveries of the seven polycyclic aromatic hydrocarbons for water and soil samples were in the range of 79.55–120.0 and 78.76–120.8%, respectively. The relative standard deviations for the determination of the analytes in water and soil samples were lower than 11 and 10%, respectively. The method is simple and suitable for the determination of polycyclic aromatic hydrocarbon residues in water and soil samples.
