ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2024; 281:116665. [PMID: 38964062 DOI: 10.1016/j.ecoenv.2024.116665] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 05/15/2024] [Accepted: 06/27/2024] [Indexed: 07/06/2024]
Abstract
Polycyclic aromatic hydrocarbons (PAHs), notably benzo[a]pyrene (BaP), are environmental contaminants with multiple adverse ecological implications. Numerous studies have suggested the use of BaP biodegradation using various bacterial strains to remove BaP from the environment. This study investigates the BaP biodegradation capability of Pigmentiphaga kullae strain KIT-003, isolated from the Nak-dong River (South Korea) under specific environmental conditions. The optimum conditions of biodegradation were found to be pH 7.0, 35°C, and a salinity of 0 %. GC-MS analysis suggested alternative pathways by which KIT-003 produced catechol from BaP through several intermediate metabolites, including 4-formylchrysene-5-carboxylic acid, 5,6-dihydro-5,6-dihydroxychrysene-5-carboxylic acid (isomer: 3,4-dihydro-3,4-dihydroxychrysene-4-carboxylic acid), naphthalene-1,2-dicarboxylic acid, and 2-hydroxy-1-naphthoic acid. Proteomic profiles indicated upregulation of enzymes associated with aromatic compound degradation, such as nahAc and nahB, and of those integral to the tricarboxylic acid cycle, reflecting the strain's adaptability to and degradation of BaP. Lipidomic analysis of KIT-003 demonstrated that BaP exposure induced an accumulation of glycerolipids such as diacylglycerol and triacylglycerol, indicating their crucial role in bacterial adaptation mechanisms under BaP stress. This study provides significant scientific knowledge regarding the intricate mechanisms involved in BaP degradation by microorganisms.

Abstract
BACKGROUND Incomplete combustion of wood releases toxic chemicals. Exposure to these chemicals during charcoal production can modulate redox status of cellular system which may further lead to genomic instability and of antioxidant enzymes. Genetic polymorphism may alter the functioning properties of these enzymes and modulate the response to oxidative stress. METHODS In this study, we analyzed the link between genetic polymorphism and enzyme activity for antioxidant enzymes: MnSOD and GPx-1 in charcoal workers and control population. This study included 77 charcoal workers and 79 demographically matched healthy control subjects. This association was studied using multiple linear regression, adjusted for confounding factors viz. age, consumption habits and exposure duration. RESULTS SOD activity was lower for TT genotype (3.47 ± 0.66; 5.92 ± 1.08) versus CC genotype (3.47 ± 0.66; 6.67 ± 1.60) in control and charcoal workers respectively. Significant lower GPx-1 activity was found in leu/leu genotype (7.25 ± 0.38; 3.59 ± 0.57) when compared to pro/pro genotype (7.78 ± 0.59; 4.28 ± 0.71) and pro/leu genotype (8.48 ± 0.34; 4.30 ± 0.76) in control population and charcoal workers respectively. A significant difference in the levels of 1-Hydroxypyrene (biomarker of exposure) and SOD and GPx-1 activity (biomarkers of oxidative stress) was evident in exposed group in comparison to the control one. CONCLUSION Collectively, our findings suggested that PAH influenced the mode of action of SOD and GPx-1 which were impacted by polymorphism in SOD and GPx-1 gene. Hence, polymorphism of MnSOD and GPx-1 genes were found to play a modulatory role in human susceptibility to oxidative damage induced by wood smoke in charcoal workers.

Abstract
A weak CL emission was initiated by peroxynitrous acid (PA) produced by the interaction of nitrite with hydrogen peroxide in sulphuric acid solution. In the presence of nitrogen doped carbon dots (NCDs), the CL intensity was enhanced significantly. The CL mechanism of the NCDs-PA system was studied using the CL spectrum, FL spectrum and the effect of radical scavengers. The NCDs-PA CL system was developed for the determination of 2-naphthol (2-NAP) based on its inhibition effect. The reduced CL intensity was proportional to the concentration of 2-NAP in the range from 0.3 to 20.0 μM and the detection limit was 48.0 nM. This method had been successfully applied to determine 2-NAP in environmental water samples with recoveries of 99.5-102.8%.

Abstract
Background Single nucleotide polymorphisms in 8-oxoguanine DNA glycosylase-1 (OGG1) gene modulates DNA repair capacity and functions as one of the first lines of protective mechanisms against 8-hydroxy-2'-deoxyguanosine (8-OHdG) mutagenicity. OGG1-Cys326 gene polymorphism may decrease DNA repair function, causing oxidative stress due to higher oxidative DNA damage. The main purpose of this study was to examine the link of oxidative and genotoxic DNA damage with DNA repair OGG1 gene polymorphism, in charcoal workers exposed to polyaromatic hydrocarbons. Methods Urinary 8-OHdG excretion (a biomarker of oxidative DNA damage) was determined in both exposed and control populations. Genotyping of OGG1 DNA repair gene in the blood samples of subjects was carried out by PCR-RFLP method. Results The 8-OHdG urinary concentration was significantly higher (p < 0.05) in the exposed (geometric mean 12.33 ± 3.78) than in the unexposed (geometric mean 7.36 ± 2.29) population. DNA damage, as measured by 8-OHdG and tail moment content, was found to be significantly higher in OGG1 homozygous mutants (mt/mt; 18.81 ± 3.34; 6.04 ± 0.52) as compared to wild-type genotypes (wt/wt; 10.34 ± 2.25; 5.19 ± 2.50) and heterozygous (wt/mt) mutants (12.82 ± 2.81; 6.04 ± 0.93) in the exposed group. Conclusion We found a significant association of OGG1 heterozygous (wt/mt) and homozygous (mt/mt) variants with oxidative and genotoxic damage, suggesting that these polymorphisms may modulate the effects of polycyclic aromatic hydrocarbons exposure in occupational workers.

Abstract
We conducted a cohort study of tandoor workers to evaluate the relationship between the biomarkers of oxidative and genotoxic damage and exposure to polyaromatic hydrocarbons. A series of oxidative and genotoxic damage biomarkers, including urinary 8-hydroxy-2′-deoxyguanosine (8-OHdG), malondialdehyde (MDA) content, and tail moment (TM) by comet assay, was studied. A total of 76 tandoor workers and 79 demographically matched healthy individuals as controls were included. Our results showed that the tandoor workers had significantly higher urinary levels of 1-hydroxypyrene, urinary 8-OHdG, MDA content, and TM compared with the control population. The concentration of all these biomarkers increased with age in the control population as well as tandoor workers. In tandoor workers, significant variation in MDA, 8-oxodG (8-oxo-2′-deoxyguanosine) and TM concentration was detected between smokers (5.08 ± 1.72 nmol/mL, 16.01 ± 4.94 ng/mg creatinine, and 5.87 ± 0.98 µm, respectively) and nonsmokers (3.84 ± 0.98 nmol/mL, 13.74 ± 3.60 ng/mg creatinine, and 5.32 ± 0.69 µm, respectively). A similar pattern was obtained for the control population. We did not obtain significant variations for alcoholics and tobacco chewers. A significant increase in all these three biomarkers was observed with the increase in the period of work exposure in tandoor workers. Multivariate regression analysis also revealed that urinary 8-oxodG, MDA, and TM were statistically significantly related to age and period of work exposure. Overall, the present study showed that the exposure to wood smoke in tandoor workers under occupational conditions led to increased DNA damage because of oxidative stress and genotoxicity. These biomarkers, therefore, are good indices to assess oxidative DNA damage in these workers exposed to occupational genotoxicants. It is also necessary to make preventive changes in work conditions and lifestyle, which will help these occupational workers to lead a healthy life.

Abstract
High-throughput screening of samples is the strategy of choice to detect occupational exposure biomarkers, yet it requires a user-friendly apparatus that gives relatively prompt results while ensuring high degrees of selectivity, precision, accuracy and automation, particularly in the preparation process. Miniaturization has attracted much attention in analytical chemistry and has driven solvent and sample savings as easier automation, the latter thanks to the introduction on the market of the three axis autosampler. In light of the above, this contribution describes a novel user-friendly solid-phase microextraction (SPME) off- and on-line platform coupled with gas chromatography and triple quadrupole-mass spectrometry to determine urinary metabolites of polycyclic aromatic hydrocarbons 1- and 2-hydroxy-naphthalene, 9-hydroxy-phenanthrene, 1-hydroxy-pyrene, 3- and 9-hydroxy-benzoantracene, and 3-hydroxy-benzo[a]pyrene. In this new procedure, chromatography’s sensitivity is combined with the user-friendliness of N-tert-butyldimethylsilyl-N-methyltrifluoroacetamide on-fiber SPME derivatization using direct immersion sampling; moreover, specific isotope-labelled internal standards provide quantitative accuracy. The detection limits for the seven OH-PAHs ranged from 0.25 to 4.52 ng/L. Intra-(from 2.5 to 3.0%) and inter-session (from 2.4 to 3.9%) repeatability was also evaluated. This method serves to identify suitable risk-control strategies for occupational hygiene conservation programs.

Abstract
A capillary electrophoresis method involving online indirect chemiluminescence (CL) detection was used to determine naphthol (NAP) isomers. The method was based on the quenching effect of 1- and 2-NAP on a new CL reaction of luminol with Ni(IV) complex in an alkaline medium. Separation was conducted with a 25.0 mM sodium borate buffer containing 0.8 mmol/L luminol. Under optimized conditions, 1- and 2-NAP were baseline separated and detected in less than 8 min. The limits of detection of 1- and 2-NAP were 3.1 and 2.7 μg/L, respectively (S/N = 3), with a linear range of 4.0-80.0 μg/L (r > 0.995). Analysis of real samples demonstrated that the spiked recoveries were in the range of 89.2-107.5% (n = 3). The proposed method was successfully used to determine 1- and 2-NAP contents in three environmental water samples and 14 human urine samples. No derivatization or tedious pretreatment was required in the analysis. The proposed method is a potential approach for routine tests of naphthol isomers in a facile CE-CL system.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants and well-known carcinogens. Hydroxy derivatives of PAH are considered as biomarkers of PAH exposure, and there is a need to measure these metabolites at low concentrations. So, a precise and eco-friendly analytical method has been developed for rapid determination of PAH metabolites. For the first time, a new analytical method based on coupling of dispersive liquid-liquid microextraction (DLLME) with auto-injector port silylation (auto-IPS) followed by gas chromatography-tandem mass spectrometry (GC-MS-MS) analysis is reported for the analysis of seven urinary PAH metabolites. Factors affecting DLLME and IPS, such as type and volume of extraction and disperser solvent, pH, ionic strength, injector port temperature, volume of N,O-bis(trimethylsilyl)trifluoroacetamide and type of solvent were investigated. Under optimized conditions, the limit of detection and limit of quantification were found to be in the range of 1-9 and 3-29 ng/mL, respectively. Satisfactory recoveries of metabolites in urine samples in the range of 87-95% were found. The developed method has been successfully applied for the determination of PAH metabolites in urine samples of exposed workers. DLLME-auto-IPS-GC-MS-MS method is time, labor, solvent and reagent saving, which can be routinely used for the analysis of urinary PAH metabolites.
