PM2.5 and PM>2.5 samples were collected in Cotonou (Benin) using high volume cascade impaction air samplers. The samplings based on continuous collection over twelve days. Physical chemical characteristics of determined by size distribution (laser granulometry), specific surface areas (BET method), inorganic elements (ICP-MS), water-soluble ions (IC), CHNS analysis organic compounds (GC-MS). Average concentrations particulate matter 180.9 µg/m3 94.5 PM>2.5, respectively. higher...
Indoor air pollution constitutes a public health problem due to the long time that individuals spend in enclosed spaces every day. The present study aims investigate level of volatile organic compounds (VOCs) indoor households Senegal, and assess risks related residents’ exposure. Of 17 VOCs identified, 16 were detected Medina accommodations versus 14 Darou Khoudoss. Toluene levels reached 70.9 μg/m3 18.5 Khoudoss, which highest compared other compounds. sum Benzene, Toluene, Ethylbenzene,...
This study deals with the health effects within a child population, neighbouring landfill. After detecting metals in soil and air samples collected surroundings of landfill control site, we have studied: (i) levels lead (Pb) exposure biomarkers blood urine, (ii) oxidative stress (iii) renal injury by applying set early effect biomarkers. Levels Pb were higher exposed site (i.e. 1129 mg/kg 640 ng/m 3 samples, respectively) versus those 14.3 9.3 respectively). impregnation delta-aminolevulinic...
Airborne particulate matter (PM) toxicity is of growing interest as diesel exhaust particles have been classified carcinogenic to humans. However, PM a mixture chemicals, and respective contribution organic inorganic fractions remains unclear. Thus, we analysed the link between chemical composition samples bulky DNA adduct formation supported by CYP1A1 1B1 genes induction catalytic activities. We used six native samples, collected in industrial, rural or urban areas, either during summer...
The aim of this study was to assess the integrity and kidney overall functional capacity subjects exposed landfill emissions. Urine blood levels Pb Cd, several newly biomarkers nephrotoxicity (Kim Injury Molecule 1 (KIM-1), alpha-1 Microglobulin (α1 M), beta-2 (β2 Cystatin-C (Cyst C), Clusterin, alpha-glutathione S-transferase (GSTα), pi-glutathione (GSTπ), Tissue Inhibitor Metalloproteinase-1 (TIMP1), Calbindin, Neutrophil Gelatinase-Associated Lipocalin (NGAL), Osteopontin (OPN), (Retinol...
This work concerns atmospheric particles (PM 2.5) collected in the surroundings of rural, urban and industrial areas. The investigation zone chosen for study is Dunkirk (North France), a highly industrialised city located along North sea, where various activities are present such as metallurgy, petrol refineries other chemical companies but also an important with 210 000 inhabitants two loaded motorways. Comparisons rural area were carried out. Physicochemical analysis particulate matter was...
Exposure to high-concentration of benzene in polluted air has been associated with bone marrow deficiency, aplastic anemia and leukemia. However, epidemiological studies have reported conflicting data following human exposure levels below 1 ppm (that is, 3.2 mg/m3). Therefore we investigated the influence outdoor on peripheral blood cells among exposed motor-biketaxi drivers (MBTD) which specific IgG antibodies against reactive metabolites, such as hydroquinone (HQ) para-benzoquinone (p-BQ)...
Volatile Organic Compounds (VOCs) are known to be hazardous and harmful human health the environment. In mixtures or during repeated exposures, significant toxicity of these compounds in trace amounts has been revealed. vitro air-liquid interface approaches underlined interest evaluating impact VOC exposure importance carrying out a toxicological validation techniques addition standard chemical analyses. The difficulties sampling measuring VOCs stationary source emissions due both complexity...
A room-temperature continuous-wave (CW) quantum cascade laser (QCL)-based methane (CH4) sensor operating in the mid-infrared near 8 μm was developed for continuous measurement of CH4 concentrations ambient air. The well-isolated absorption line (7F2,4 ← 8F1,2) ν4 fundamental band located at 1255.0004 cm−1 used optical concentration by direct a White-type multipass cell with an effective path-length 175 m. 1σ (SNR = 1) detection limit 33.3 ppb 218 s achieved precision 1.13%. deployed campaign...
Pyrotechnic smokes are widely used in civilian and military applications. The major issue arise from the release of particles after smoke combustion but health risks related to their exposure poorly documented whereas toxicity airborne on respiratory target very well known. Therefore, this study aimed explore vitro particle fraction different pyrotechnic smokes. Particles a red signalling (RSS), an hexachloroethane-based obscuring (HC-OS) anti-intrusion (AIS) were collected cloud. RSS...
If the use of biomass and wood in particular replaces fossil fuels for heat production, this has to be made conditions controlled minimize environmental health impacts. Two recent French domestic appliances presenting high technology adjustment different hot air entrances (secondary postcombustion) were tested with regard their particulate gaseous pollutants (total suspended particles (TSP), matter diameter below 2.5 μm (PM2.5), carbon monoxide (CO), total hydrocarbons compounds (THC))...
