Abstract Human exposure to bisphenol A (BPA) has recently received special attention. It been shown that BPA may occur through the consumption of beverages or foods have in contact with polycarbonate (PC) plastic containers epoxy resins food packaging. migration study was conducted using a variety containers, including baby bottles, non-PC bottle liners, and reusable PC drinking bottles. Water used simulate into aqueous acidic foods; 10% ethanol solution low- high-alcoholic 50% fatty foods....
A series of perfluorinated compounds (PFCs) including perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have been recently measured in a variety environmental samples biological matrices. In order to better understand the human exposure routes these chemicals, levels PFOS, PFOA, perfluorobutane (PFBS), perfluorohexane (PFHS) sulfonamide (PFOSA) house dust were investigated. The data revealed correlation between concentrations PFCs percentage carpeting house; older houses...
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),...
Phthalates have been used extensively as plasticizers to improve the flexibility of polymers, and they also found many industrial applications. They are ubiquitous in environment detected a variety environmental biological matrices. The goal this study was develop method for determination 17 phthalate esters house dust. This involved sonication extraction, sample cleanup using solid phase isotope dilution GC/MS/MS analysis. Method detection limits (MDLs) recoveries ranged from 0.04 2.93 μg/g...
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...
A pilot study was conducted to provide preliminary data on the concentrations of perfluorooctanesulfonate (PFOS), perfluorooctanoic acid (PFOA) and perfluorooctanesulfonamide (PFOSA) in blood Canadians. set 56 human serum samples collected from non-occupationally exposed Canadians analyzed by microbore HPLC-negative ion electrospray tandem mass spectrometry. PFOS main component perfluorinated organic compounds (PFCs) detected all specimens at an average concentration 28.8 ng mL−1 a range 3.7...
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...
An integrated analytical method for the simultaneous determination of five parabens (methyl-, ethyl-, propyl-, butyl-, and benzyl-), triclosan, methyl triclosan in indoor house dust was developed based on gas chromatographic-mass spectrometric technique (GC/MS). Analytes were extracted from samples by sonication. After sample cleanup solid-phase extraction (SPE), extracts derivatized with N-methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA) then analyzed chromatography coupled ion trap mass...
Bisphenol A (BPA) is a high production volume (HPV) chemical used to make polycarbonate (PC) plastics and epoxy resins. Due its potential adverse health effects, BPA has been restricted or banned in some products thus many alternatives have introduced into the market. Most of these such as bisphenol S (BPS), F (BPF), M (BPM), similar structures termed analogues (BPAAs). In this study, method was developed for simultaneous determination 16 BPAAs indoor dust by gas chromatography coupled with...
This study investigated the occurrence of 19 aryl phosphates and mixed alkyl-aryl in dust samples (n = 144) collected under Canadian House Dust Study (CHDS). The predominant target analytes, detected 100 % samples, were isodecyl diphenyl phosphate (IDDPP), cresyl (CDPP), isopropylated triaryl (ITPs), with median concentrations 1225 (248–17850) ng/g, 91 (14–57700) 805 (203–152000) respectively. ITPs included isopropylphenyl (IPPDPP), bis(isopropylphenyl) phenyl (BIPPPP), tris(isopropylphenyl)...
Malaria devastates sub-Saharan Africa; the World Health Organization (WHO) estimates that 212 million people contract malaria annually and plasmodium virus will kill 419 000 in 2017. The disease affects rural populations who have least economic means to fight it. Impregnated mosquito nets reduced mortality rate but Anopheles mosquitoes are changing their feeding patterns become more active at dusk early morning rather than after 22h00 as an adaptation nets. Everyone is susceptible these...
