The daily variation of organic contaminants, both gaseous and associated with suspended particulate matter, was investigated within the National Company of Paintings estate in Lakhdaria, Algeria, spanning the period 2014-2015. The research emphasizes the chemical characterization of suspended particulate matter, analyzing a range of organic compounds, including n-alkanes, polycyclic aromatic hydrocarbons (PAHs), and highly polar organics (HPOC), such as phthalate esters and heterocyclic compounds. Vapours of PAHs and polychlorobiphenyls (PCBs) were also analyzed. Low molecular weight compounds were primarily associated with the gas phase (2-ring PAHs, approximately 95%; 3-ring PAHs, around 70%), while high molecular weight congeners were mainly associated with the particle phase (6-ring PAHs, 55%). The concentrations of PCBs (ranging from 0.6 to 42 ng m-3) were higher than those reported in other cities in Algeria and Europe. The source reconciliation of organic contaminants through principal component analysis (PCA) demonstrated that the primary sources were petroleum combustion, industrial manufacturing, tobacco smoking, and vehicular traffic. The significance of tobacco smoke was further confirmed by the analysis of PAHs diagnostic ratios. The variations in diagnostic ratio rates between gaseous and particulate PAHs were attributed to distinct contributions from sources such as industrial processes. Health risks for workers exposed to PAHs and PCBs in PM10 were quantitatively assessed in terms of Benzo[a]pyrene equivalent concentration (BaPeq) and incremental lifetime cancer risk (ILCR). ILCR presents novel findings, showcasing heightened risks among workers exposed to specific PAHs within production areas, whereas that related to PCBs suggested a high potential health risk for laboratory workers.

Benzene is associated with diverse occupational and public health hazards. It exhibits an ability to rapidly permeate the skin and contaminate water and food sources, leading to dermal and ingestion exposures. Despite numerous studies examining the associations between benzene and various indicators of harm, the findings have yielded inconsistent results. Furthermore, relying solely on air concentration as a measure of benzene exposure is limited, as it fails to account for internal exposure dose and individual susceptibility. This study aimed to conduct a comprehensive review in order to present current knowledge on benzene biomarkers and their significance in evaluating exposure levels and associated health hazards. The search methodology adhered to the PRISMA guidelines and involved the application of specific inclusion and exclusion criteria across multiple databases including PubMed, Embase, and Web of Science. Two researchers independently extracted and evaluated the relevant data based on predetermined criteria. Following the screening process, a total of 80 articles were considered eligible out of the initially retrieved 1053 articles after undergoing screening and assessment for inclusion. As the level of exposure decreased, specific biomarkers demonstrated a gradual increase in limitations, including heightened background concentrations and vulnerability to confounding factors. The advancement of sampling and analysis techniques will yield new biomarkers. Additionally, when conducting practical work, it is crucial to employ a comprehensive utilization of diverse biomarkers while excluding individual metabolic variations and combined exposure factors.

Introduction: Lead (Pb) occupational exposure in painters has been documented to be contacted via additives in paints due to its many important properties and vitamin C has been the most widely studied when it comes to Pb- induced oxidative stress.  Aim: This study aimed at the use of freshly squeezed orange-juice due to its accessibility in investigating the modulating role of synthetic and natural vitamin-C on leaded paint-induced nephrotoxicity of automobile painters.  Study Design and Methods: Sixty (60) male automobile painters were consecutively selected and divided equally into 2 groups. Vitamin-C and orange juice were administered daily to painters for 4 weeks at dosage levels of 200 and 184 mg/day respectively. Thirty (30) male non-painters constituted the control group. Orange juice vitamin-C content was assessed by titrimetric method and synthetic vitamin-C served as the standard drug. Renal biomarkers and reduced glutathione (GSH) were done by Colorimetry. Urine aminolevulinic acid (ALA) and Pb were assessed by ELISA technique and atomic absorption spectrophotometry respectively. Phytochemical screenings (quantitative/qualitative) and proximate analysis were done using standard methods. Data were analyzed using Pearson’s correlation coefficient and One-way Analysis of Variance (ANOVA) followed by Tukey’s post-hoc test for pairwise comparison. Statistical significance was p< 0.05.  Results: Baseline results at 0-week of orange juice administered group showed a significantly (P<0.05) higher serum Pb, urea and creatinine compared to non- painters. Also, their urine baseline results at 0-week showed a significantly (P<0.05) higher levels of ALA and GSH compared to non-painters. Orange juice administration at 4 weeks showed significant (P<0.05) reductions in concentrations of lead, urea, and creatinine in serum, decreased concentrations of GSH and ALA in urine but increased urine Pb compared to baseline. However, compared with baseline, after 4 weeks of vitamin-C supplementation, serum Pb, urine GSH, and urine ALA were significantly (P<0.05) reduced and urine Pb significantly (P<0.05) increased. A positive correlation was observed at 2-weeks of taking orange- juice between serum lead and urine ALA (r= 0.703) and GSH (r= 0.913) but 4-week positive correlation between urea and urine GSH (r= 1.000). A negative correlation was observed at 2-week of taking vitamin-C between serum creatinine and urine lead (r= -0.857) while 4-week a negative correlation was observed between urine GSH and urine lead (r= -0.743). Presence of tannin, phenol, saponin, alkaloid, and flavonoid was detected in orange juice.  Conclusion: Orange juice administration conferred significant amelioration to renal and lead toxicity biomarkers by 4 weeks. The presence of phytochemicals suggests why orange juice may be a viable alternative in amelioration of toxic effects of leaded paint among automobile painters.
