Aromatic amine antioxidants (AAs), extensively used in rubber products, and their ozone-photolyzed product p-phenylenediamine quinones (PPD-Qs) were found to be pervasive various environments with potential ecological health risks. The relationship between external internal exposure these contaminants risks the general population remain poorly explored. Herein, dust–handwipe–urine samples (n = 97 pairs) from families Tianjin, China was collected for analyzing 20 AAs 6 PPD-Qs (including...
Oil refinery activity can be an emission source of perfluoroalkyl and polyfluoroalkyl substances (PFAS) to the environment, while contamination profiles in soils remain unknown. This study investigated 44 target PFAS soil samples collected from oil Southeastern China, identified novel PFAS, characterized their behaviors by assessing changes before after employing advanced oxidation using a combination nontarget analysis total oxidizable precursor (TOP) assay. Thirty-four were detected...
Liquid crystal monomers (LCMs) are indispensable materials in liquid displays, which have been recognized as emerging persistent, bioaccumulative, and toxic organic pollutants. Occupational nonoccupational exposure risk assessment suggested that dermal is the primary route for LCMs. However, bioavailability possible mechanisms of to LCMs via skin absorption penetration remain unclear. Herein, we used EpiKutis 3D-Human Skin Equivalents (3D-HSE) quantitatively assess percutaneous nine LCMs,...
Abstract BACKGROUND Numerous studies have addressed the positive effects of organic amendments on soil and plant productivity under short‐term field studies. However, to date, few been conducted amendment orchards where high nutrient bioavailability is required. This study deals with biochar compost quality, growth yield a replanted apple orchard in northeast Iran. RESULTS Biochar+compost application resulted 37% 300% higher total carbon available phosphorus content, respectively, during...
During two consecutive summer and winter seasons in Lahore, the health risk of air dust-borne polycyclic aromatic hydrocarbons (PAHs) was evaluated. Gas chromatography/mass spectrometry (GS/MS) used to determine dust samples from various functional areas across city. The mean ∑16PAHs were higher 1035.8 ± 310.7 (pg m-3) 963.4 289.0 (ng g-1 d.w.) during as compared 1010.9 303.3 matrices 945.2 283.6 d.w.), respectively. PAHs ring profile recognized 3 4 rings most dominant samples. Estimated...
Recently, evidence of aromatic amine antioxidants (AAs) existence in the dust electronic waste (e-waste) dismantling area has been exposed. However, there is limited studies investigating occupational exposure and toxicity associated with AAs their transformation products (p-phenylenediamines-quinones, i.e., PPD-Qs). In this study, 115 42 hand wipe samples collected from an e-waste recycling industrial park central China were analyzed for 19 6 PPD-Qs. Notably, median concentration ∑6PPD-Qs...
Electronic waste is an emerging source of per- and polyfluoroalkyl substance (PFAS) emissions to the environment, yet contribution from hazardous recycling practices in South Asian region remains unclear. This study detected 41 PFAS soil samples e-waste sites Pakistan total concentrations were 7.43–367 ng/g dry weight (dw) (median: 37.7 dw). Trifluoroacetic acid (TFA) 6:2 fluorotelomer sulfonic emerged as dominant PFAS, constituting 49% 13% concentrations, respectively. Notably, nine...
Extensive use of Pesticides in agriculture and its surface runoff river water is a major environmental concern. The present study evaluated the phytoremediation potential Eichornia crassipes, Pistia strateotes algae (Chaetomorpha sutoria, Sirogonium sticticum Zygnema sp.) for organochlorine pyrethroid pesticides. Water plant samples were extracted by liquid phase solid extraction respectively analyzed high-performance chromatography. Eleven treatments (T1-T11) with without plants used During...
The objective of this study was to assess the occupational exposure mercury in dentistry and associated environmental emission wastewater Lahore, Pakistan. A total ninety-eight blood samples were collected comprising 37 dentists, 31 dental assistants, 30 controls. Results demonstrate that personnel contained significantly higher mean concentration their (dentists: 29.835 µg/L assistants: 22.798 µg/L) compared controls (3.2769 µg/L). found maximum older age group (62.8 dentists (44.3...
