Ingestion of polycyclic aromatic hydrocarbons (PAHs) contaminated water has potential human-health and ecological consequences. A comprehensive investigation PAHs' occurrence distribution in the surface sediment samples Damodar River Basin was conducted using Agilent 7890B Gas Chromatograph (GC-FID) coupled with 5977A Mass Spectrometry. The results showed that concentrations individual PAHs sediments ranged from ND to 36 μg/L 582 ng/g highest detected levels 3-ring PAH Acenapthylene (ACY)...
Industrial areas play an important role in the urban ecosystem. site environmental quality is linked to human health. Soil samples from two different cities India, Jamshedpur and Amravati, were collected analyzed assess sources of polycyclic aromatic hydrocarbons (PAHs) industrial their potential health risks. The total concentration 16 PAHs JSR (Jamshedpur) varied 1662.90 10,879.20 ng/g, whereas ranged 1456.22 5403.45 ng/g soil AMT (Amravati). dominated by four-ring PAHs, followed five-ring...
Concentrations of polycyclic aromatic hydrocarbons (PAHs) and n-alkanes are determined in atmospheric aerosol samples collected from an academic campus, Department Chemistry, National Institute Technology, Jamshedpur, India. The sampling work carried out for the present study was June to September 2018. maximum concentration PAHs observed be 6.02 ng/m3 (June) 23.02 (September), minimum 5.36 (July) 10.13 (June), respectively. average level ∑17 ∑13 estimated 15.62±5.51 5.69±0.33 ng/m3,...
Emissions of black carbon (BC) and polycyclic aromatic hydrocarbons (PAHs) from various anthropogenic activities are often reported, yet cultural practices such as the multi-day Diwali festival its influences on emissions these compounds overlooked. Major during this include burning rows oil-filled earthen lamps (diyas) fireworks (bursting crackers). A comprehensive field investigation was conducted to document role celebrations releases BC PAHs ongoing Covid pandemic. The results show that...
Charge transport through<italic>Geobacter sulfurreducens</italic>biofilms increases with film thickness, as more porous films improves ion upon electrolysis.
Surface chemistry is known to influence the formation, composition, and electroactivity of electron-conducting biofilms. However, understanding evolution microbial composition during biofilm development its impact on electrochemical response limited. Here we present voltammetric, microscopic community analysis biofilms formed under fixed applied potential for modified graphite electrodes early (90 h) mature (340 growth phases. Electrodes introduce hydrophilic groups (-NH2, -COOH -OH) enhance...
Abstract Real-time black carbon (BC) and fine particulate matter (PM) were collected from January to December 2017 with a portable Aethalometer air sampler in the urban environment of Jamshedpur, India. In present study, diurnal seasonal variations BC meteorological variables analysed. The variation ranged 2.1 15.5 gm-3, lowest concentration during monsoon season highest winter season, because most PM are settled down. annual mean mass was observed at 6.22 ± 3.95 µgm −3 . While, 2.5 varied...
Abstract Atmospheric PM2.5 size particulate-associated Polycyclic Aromatic Hydrocarbons (PAHs) were analyzed from December 2018 to May 2019 over three traffic sites of Chota Nagpur Plateau (CNP) India study their temporal and seasonal variations. Over the last few decades, CNP becomes a hotspot air pollution due anthropogenic activities. The concentration was higher than value given by National Ambient Air Quality (NAAQ) standard value. results show total average PAHs found 141.48±22.86,...
Introduction of arylamine functional groups to graphite electrodes results in improved initial catalysis for acetate oxidation by microbial biofilms over that observed on unmodified anodes. Arylamine modified anodes achieve a current density 3.4 A m−2 whilst only 1.3 during the first batch feed cycle. The surface functionalization strategy provides route enhancing bioelectrochemical systems process performance and studying complex mechanisms involved such systems.
