“…It becomes decisive from previous studies that gas chromatography (GC) is a reliable technique to isolate DEHP from different source material. 25,26 A total ion chromatogram derived from a gas chromatographic analysis (Figure 1) shows a single, significant peak with 100% relative abundance (RA) at the retention time 33.09 minutes. The peak covers 86.31% of the total area of the chromatogram indicating high concentration for the detection of DEHP in the sample.…”

Di-(2-ethylhexyl) phthalate (DEHP) is a ubiquitous environmental toxicant, and finds extensive commercial application as a plasticizer to reduce the rigidity of polyvinyl chloride. Besides numerous negative impacts on environment and public health, the compound exhibits acute bioactivity against microbes and has therapeutic value too. Considering this biochemical significance, searching of its new biogenic sources has become an active area of research. Here, DEHP is identified from the biomass of a toxic strain of Anabaena circinalis, which is quite unobvious, and simultaneously, the in vitro physical conditions are optimized by using a swarm-based multiparameter optimization technique. A purified fraction collected from column chromatography is subjected to gas chromatography (GC) to fetch the compound peak and then subsequent mass analysis for its identification. The mass spectrum describes the molecular weight along with the structure of DEHP with 99.9% experimental accuracy. An experimental observation table has been used to frame a fitness function using the curve fitting approach when temperature (T), light and dark period (LD), and duration of subculture cycle (DSC) are considered as the target parameters to be optimized. The optimum values obtained for T, LD, and DSC are 20°C, 14:10 hour light and dark ratio approximately, and 40 days, respectively. This experimental finding of A. circinalis FSS 124 as a novel source of DEHP and subsequent optimization using soft computing tools might be a benchmark for process optimization in biological research.

“…The selection of different solvents for extraction can have significant effects on the discrimination of target analytes from the sample matrix, as well as the extraction recoveries [ 32 ]. Although the advantage of this sample preparation is simple without purification, the matrix effect based on the different organic plastic additives in infusion sets can lead to false results of target analytes [ 33 ]. As an extraction solvent after the polymer dissolution, hexane was chosen because the partitioning of the extract with hexane was able to minimize matrix interferences compared with other solvents.…”

A method for the quantitative determination of dibutyl phthalate (DBP), benzyl butyl phthalate (BBP), bis(2-ethylhexyl) adipate (DEHA), bis(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DNOP), dioctyl terephthalate (DOTP), diisononyl phthalate (DINP), and diisodecyl phthalate (DIDP) in medical infusion sets was developed and validated using gas chromatography coupled with triple quadrupole mass spectrometry (GC-MS/MS) in the multiple reaction monitoring (MRM) mode. Solvent extraction with polymer dissolution for sample preparation was employed prior to GC-MS/MS analysis. Average recoveries of the eight target analytes are typically in the range of 91.8–122% with the relative standard deviations of 1.8–17.8%. The limits of quantification (LOQs) of the analytical method were in the ranges of 54.1 to 76.3 ng/g. Analysis using GC-MS/MS provided reliable performance, as well as higher sensitivity and selectivity than GC-MS analysis, especially for the presence of minority plasticizers at different concentrations.

“…The concentration of the PAHs, phenols, (phenol, o-cresol, p-cresol and m-cresol) and selected alkylphenols was determined in the gas phase. The conditions of the sample preparation and GC-MS analysis of the selected compounds were set according to the methods described by Janoszka et al [52] for biomass burning markers, as well as according to the methods of Czaplicka et al [53] for the PAHs, Czaplicka and Kaczmarczyk [54] for the phenols, Jaworek and Czaplicka [55] for the esters of phthalic acid, and Li et al [56] for the selected alkylphenols. The samples testing procedures are presented in Figure 2.…”

In this study, the effect of the addition of waste on the emissions from coal co-combustion was investigated. Coal was co-combusted with different additions of medium-density fiberboard and polyethylene terephthalate plastic (10 and 50%), in a low-power boiler (18 W). Polycyclic aromatic hydrocarbons, phenols, alkylphenols, phthalates, and biomass burning markers emissions were determined. Gas chromatography, coupled with a mass spectrometry detector, was used to analyze these compounds in particulate matter and gas phase, after extraction and derivatization. The emissions of polycyclic aromatic hydrocarbons were the highest among all the compounds determined. The total emission of these compounds was 215.1 mg/kg for coal, and 637.7 and 948.3 mg/kg for a 10 and 50% additive of polyethylene terephthalate plastic, respectively. For the 10 and 50% additive of medium-density fiberboard, the total emission was 474.2 and 464.0 mg/kg, respectively. The 50% addition of PET also had the highest emissions of phenols (638.5 mg/kg), alkylphenols (246.5 mg/kg), and phthalates (18.1 mg/kg), except for biomass burning markers, where the emissions were the highest for the 50% addition of medium-density fiberboard (541.3 mg/kg). In our opinion, the obtained results are insufficient for the identification of source apportionment from household heating.
