We have examined several emerging brominated flame retardants (BFRs) including 2-ethyl-1-hexyl-2,3,4,5-tetrabromobenzoate (TBB), bis(2-ethylhexyl) tetrabromophthalate (TBPH), 1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE), 4,5,6,7-tetrabromo-1,1,3-trimethyl-3-(2,3,4,5-tetrabromophenyl)-indane (OBIND), and decabromodiphenyl (DBDPE) in paired human maternal serum (n = 102) breast milk 105) collected 2008–2009 the Sherbrooke region Canada. Three legacy BFRs were also included study for...
The impact of long term exposure to cholinesterase (ChE)-inhibiting organophosphate (OP) and carbamate (C) pesticides on the respiratory health agricultural workers in India was investigated.Three hundred seventy-six nonsmoking (median age 41 yr) from eastern who sprayed OP C field 348 age- sex-matched control subjects with non-agricultural occupations same locality were enrolled. Prevalence symptoms obtained by questionnaire survey, pulmonary function tests carried out spirometry. Chronic...
Exposure to organophosphate ester (OPE) flame retardants and plasticizers is widespread of concern due their toxicity. To investigate relationships between within OPE concentrations in air, dust, hands, electronic product wipes urinary metabolites with the goal identifying sources exposure pathways. Women Toronto Ottawa, Canada, provided a urine sample, two sets hand wipes, access homes for air dust sampling, completed questionnaire. were obtained floor bedroom (n = 51) most used room 26),...
Exposure to organophosphate esters (OPEs) is extensive, yet few studies have investigated their association with hormone levels or semen quality. Here, we studied the between urinary concentrations of OPEs and metabolites parameters in men (n = 117) predominantly 20-29 years age range who were recruited from greater Montreal area 2009 2012. Urine, serum, samples analyzed for OPEs, hormones, quality, respectively. Bis(2-ethylhexyl) phosphate (BEHP), bis(2,4-di-tert-butylphenyl) hydrogen...
The essential oil from the leaves of Curcuma longa L. Kasur variety grown in Pakistan was extracted by hydro-distillation. Chemical constituents were identified gas chromatography/mass spectrometry. chromatographic analysis showed 25 constituents, out which nine chemical identified. eucalyptol (10.27%) major component oil. α-pinene (1.50%), β-phellandrene (2.49%), β-pinene (3.57%), limonene (2.73%), 1,3,8-p-menthatriene (1.76%), ascaridole epoxide (1.452%), 2-methylisoborneol (2.92%),...
The impact of chronic exposure to smoke from biomass burning on respiratory health has been examined.Six-hundred and eighty-one non-smoking women (median age 35 years) eastern India who cook exclusively with (wood, dung crop residues) 438 age-matched similar neighborhood liquefied petroleum gas (LPG) were examined. Pulmonary function test was done by spirometry. concentrations particulate matter having diameter < 10 µm (PM10) 2.5 (PM2.5) in indoor air measured real-time aerosol...
The majority of households in rural India still rely on unprocessed solid biomass for domestic energy. aim this study was to investigate whether chronic exposure smoke causes activation leukocytes and the formation leukocyte-platelet aggregates. We conducted flow cytometric analysis β2 Mac-1 integrin (CD11b/CD18) expression polymorphonuclear (PMN) monocytes, P-selectin (CD62P) platelets 165 women from eastern India, who cook solely with wood, dung agricultural wastes, 155 age- socio-economic...
Bisphenol A (BPA) is used as a monomer in number of consumer products, including baby bottles and sippy cups. Some jurisdictions around the world (including Canada) have regulated production, advertising or selling polycarbonate with BPA. Following ban, makers opted for alternative materials to BPA [named analogues, BPAAs], which may not be safe promoted. The objective this project was conduct migration study cups, analyze 16 BPAAs, follow-up on conducted by Health Canada 2009. Baby (20...
Abstract Tris(2‐ethylhexyl) phosphate (TEHP, CAS no. 78‐42‐2) is a plasticizer and flame retardant, while di(2‐ethylhexyl) phosphoric acid (DEHPA, 298‐07‐7) an oil additive extraction solvent. Publicly‐available information on repeated exposure to these two related organophosphate compounds fragmentary. Hence, adult male female Fischer rats were exposed TEHP (300, 1000 3000 mg/kg body weight [BW]/day) or DEHPA (20, 60 180 BW/day) by gavage for 28 consecutive days, assess compare their...
The hydrodistilled essential oil from Xanthium strumarium L. leaves was analysed by gas chromatography-mass spectrometry. Nine out of twenty two constituents were identified X. oil. main components the β-caryophyllene (17.53%), α-cadinol (6.66%), spathulenol (6.09%), limonene (5.66%) and 1,3,5-trimethyl-2[2-nitroallyl]benzene (3.29%). Phytol (2.42%), α-muurolene (2.08%), copaene (1.47%) present in appreciable amounts. E,E,Z-1,3,12-nonadecatriene-5,14-diol (0.27%) minor amount. displayed high...
Organophosphate esters (OPEs) are used primarily as flame-retardants and plasticizers. OPEs commonly detected in various environmental matrices, food drinking water, their metabolites frequently found quantified urine. Potential adverse impacts on human health, including carcinogenicity, neurotoxicity, developmental reproductive toxicity have been well documented. Urinary concentration of OPE can vary the same individual, depending sampling time, thus introducing significant uncertainty...
