Studies have revealed the potential risks to which human health and ecosystems are exposed in the Venice Lagoon, due to the atmospheric deposition of persistent pollutants such as trace metals and organic compounds. A total of seventy-seven atmospheric bulk deposition samples were collected monthly from April 2002 to December 2004, from three sites located in the cities of Mestre and Venice, an...

Direct toxic injury to turfgrasses by atmospheric pollutants is a new factor affecting the growth and look of turfgrasses. Although the complete loss of a turf from these toxic atmospheric gases or aerosols has rarely been observed to date, the injurious effects, however, a) reduce drastically the visual quality of turfgrass, b) lowers carbohydra te reserve because of injury to plant chlorophyl...

background: volatile organic compounds (vocs) are human-made chemicals widely spread in the environment and produced by petrochemical industries and petroleum refineries. the aim of this research was to evaluate the distribution of vocs in the ambient air of mahshahr petrochemical complex, iran. methods: this study was a cross-sectional research performed in 2009. we used the method numbered 15...

Background: Ethanolic solutions of long-chain carboxylic acids can be applied to lead metal substrates to form a coating of lead carboxylate which provides protection against atmospheric pollutants. Results and conclusions: In this paper we describe the optimal inhibitor concentration for the coating on lead. Electrochemical impedance data taken before and after immersion in media modelling oak...

Coagulation of combustion generated nanoparticles and their measurement behind vehicle engines: can they play a role as atmospheric pollutants? H.-H. Grotheer, T. Gonzalez Baquet, M. Thierley, H. Pokorny, and M. Aigner DLR Institute of Combustion Technology, Pfaffenwaldring 38–40, 70569 Stuttgart, Germany Received: 25 February 2005 – Accepted: 31 March 2005 – Published: 10 June 2005 Corresponde...

A high-resolution differential optical absorption spectroscopy (DOAS) system for long-path atmospheric pollution monitoring is described. The system, consisting of a broadband lamp and a dispersive, fast-scanning optical receiver, separated by a few kilometers, was used in measurements of different pollutants, highlighted by the monitoring of the local concentration of atomic mercury. Mercury l...

In this study we investigate the e ect of varying the ratio of false-positive and false-negative misclassi cation costs on the sensitivity and selectivity of binary predictions of exceedences of atmospheric pollutants. This allows us to determine a window of values for this ratio for which it is worthwhile making de nite rather than probabilistic predictions. The support vector machine provides...

Fuel cells have the potential to provide environmentally-friendly sources of energy for transportation, portable, and stationary applications. Because fuel cells convert chemical energy directly to electrical energy, high efficiencies can be realized. Production of electrical power from fuel cells has several other advantages. There are no moving parts. Fuel cells operate noiselessly with no fr...

Meteorological parameters play a significant role in affecting ambient air quality of an urban environment. As Dhaka, the capital city of Bangladesh, is one of the air pollution hotspot among the megacities in the world, however the potential meteorological influences on criteria air pollutants for this megacity are remained less studied. The objectives of this research were to examine the rela...

moisture and air pollutions intensify metallic and nonmetallic surface corrosions. corroded surfaces exposed to rain washing cause pollution transportation in water and soil environment, especially in industrial areas. investigation of storm runoff quality in pars special economic energy zone (pseez) has shown heavy metals in storm basins of gas refineries and petrochemical industries.in this p...
