Odour is a major concern as they are termed hazardous to the surroundings as well as life forms when they are exposed to the environment. Odour emission is also one of the indicators of environmental changes that impact the environment. Among the different sources of odour emission, in the dumping...

Polycyclic Aromatic Hydrocarbons (PAHs) are aromatic hydrocarbons with three or more fused benzene rings that include carbon and hydrogen. These are thought to be harmful to human health, and we cannot avoid being exposed to them because they are widely disseminated throughout the environment. PAHs...

The aim of current study was to evaluate the polycyclic aromatic hydrocarbons (PAHs) concentration and probabilistic health risk in vegetables and fruits samples of Tehran city, Iran during 2018-2019 using magnetic solid-phase extraction (MSPE)and gas chromatography-mass spectrometry(GC-MS).The...

Biological treatment is one of the most preferable strategies to complete and safe removal of pollutants. Pyrene (PY) is the first member of high molecular weight polycyclic aromatic hydrocarbons (HMW-PAHs) that represents various concerns to biological life and human health. In this study, two...

In this study, the potential use of Azolla filiculoides Lam. for the bioremediative solution to polycyclic aromatic hydrocarbon (PAH) pollution due to crude oil spills in freshwater was investigated. The plants were grown in nitrogen-free Hoagland nutrient solution media containing 0.05%, 0.1%, 0.2%...

In the present investigation, an attempt for the reduction of six hazardous air Pollutants (HAPs) from diesel exhaust by different blends of diesel and biodiesel has been made. The synthesis of biodiesel has been done from Jetrofa, Linseed Castor and Karanja oils which are commonly used in the...

The aim of this study is to investigate the performance of solar photo-catalyst of titanium oxide (TiO2/Solar) process to treat rainwater. The polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs) in rainwater were chosen to be investigated in this study. The rainwater...

Polycyclic aromatic hydrocarbons (PAHs) are a group of quotidian organic compounds having between two and six condensed aromatic rings braced in angular, cluster or linear forms possessing hydrogen and carbon atoms only. This work aims to evaluate the physicochemical characteristics of soil as...

Indoor dust samples were collected in the summer of 2017 from 10 residential buildings, 7 commercial buildings and 7 official buildings of Bushehr. Sixteen polycyclic aromatic hydrocarbons (PAHs) were analyzed by GC–MS. The sum concentration of the 16 PAHs in dust spanned between 87.8 to 14619 mgkg...

In this work, diesel soot has been characterized chemically using a diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) technique. Diesel soot samples were generated under combustion conditions reproducing the typical urban operating mode of a diesel engine. Initial experiments...

Marine sediment contamination was evaluated in a set of sediment specimens collected from Izmir Bay (Turkey) and from Mytilene Harbor (Greece) in the Aegean Sea. Eight sediment specimens from Izmir (#IZ to #IZ8) and seven sediment specimens from Mytilene (#MYT1 to #MYT7) were analyzed for their...

The concentrations of ozone, NO2 and SO2 measured by a Differential Optical Absorption Spectroscopy (DOAS) system in the city of Kozani in Northwestern Greece are presented and compared against data from a conventional ground station. This was made in order to assess DOAS performance in a...

The volume mixing ratios of non-methane hydrocarbons including saturated, unsaturated and aromatic ones (C2 to C8 as non methane hydrocarbons, NMHCS) were measured at three distinct sites (natural, rural, urban) in the lower troposphere of the Eastern Mediterranean from February 2006 to March 2007...

The levels and the distribution of metals, hydrocarbons and organochlorine compounds were studied in mussels (Mytilus galloprovincialis) and surface sediments collected from Thermaikos gulf in March 1999. Hydrocarbon values were indicative of moderate pollution, whereas in some cases clear evidence...

The present paper examines a small and deep (53 m) salty lake, as well as the adjacent harbor of Aghios Nikolaos (Crete). The survey was carried out in 1996. Physicochemical parameters indicated that the main characteristics of the system are the inflow of karstic water from underwater springs...

Accumulation of airborne pollutants in vegetation is an important initial step in the uptake process of the terrestrial food web, providing direct and indirect routes by which biota and, eventually, humans are exposed to chemicals. A set of algorithms for estimating atmospheric pollutant...

Estimates of the amount of secondary organic aerosol formed in the atmosphere from the degradation of traffic C6-C12 hydrocarbon emissions in the city of Athens are presented. Around 1.26 tn of organic aerosol is estimated to be produced during a six hours air pollution episode from the aromatic...

The work deals with coal combustion in a pilot-plant fluidised bed (7 cm i.d.) under atmospheric conditions. The aims are to capture and analyse qualitatively as well as quantitatively the volatile polycyclic hydrocarbons emitted by using coal as energy source under various combustion conditions...

About 140 samplings of fine and coarse particles were gathered during the year 2006 in Kozani that represent an urban area surrounded by opencast coal mining. A low volume dichotomus sampler has been used to trap suspended particles. The filters used were teflon, which are ideal for analysis in the...

Traffic emissions and tobacco smoke are considered two main sources of polycyclic aromatic hydrocarbons (PAHs) in indoor and outdoor air. In this study, the impact of these sources on the level of fine particulate matter (PM2.5) and on the distribution of 15 PAHs regarded as priority pollutants by...

Polycyclic Aromatic Hydrocarbons (PAHs) are one of the major categories of pollutants entering the marine environment and finally accumulating in the sediments. Their occurrence raises major concerns for human health, especially during coastal activities (bathing waters, aquaculture, etc), having...

Through transportation accidents or intentional releases, plastic pellets (small granules 1-5 mm in diameter) are widely distributed in the ocean all over the world. These pellets accumulate organic pollutants and can be used for the determination of diffusive seawater pollution. Pellets...
