The measurement and analysis of inherent optical properties (IOPs) of the main water constituents are necessary for remote-sensing-based water quality estimation and other ecological studies of lakes. This study aimed to measure and analyze the absorption and backscattering coefficients of the main water constituents and, further, to analyze their relations to the water constituent concentratio...

since particulate matter (total suspended particles and particulate matter with median aerodynamic diameter less than 10 µm) is one of the important pollutants in the ambient air of tehran, the capital of iran, organic substances, inorganic substances and lead levels in tsp and pm10, correlation between tsp and pm10 concentrations, ratio among the two fractions and relation between tsp and pm10...

under the contemporary scenario of global climate change and increasing coastal eutrophication, baseline studies of phytoplankton diversity and distribution in relation to habitat conditions constitute the first approach to evaluate potential shifts at the base of the food webs. here we present data of phytoplankton species composition and environmental variables in winter 2006 in a temperate ...

The human respiratory system is the gateway of entry for inhaled detritus from anthropogenic (e.g. combustionderived (CD) particulate matter (PM; e.g. diesel exhaust and wood-burning PM). Adult humans inhale 20m 3 of air and suspended debris (gases and particles) into the airways daily. Inhalation exposure to CDPM (Figure 1) is known to increase the risk of morbidity and mortality of lung and h...

Technological procedure of extracting metals is being constantly modernised so that polluting of the basic life resources is reduced. Emissions of waste gases and particulate matter are still present in larger mining-metallurgical complexes. Mining-metallurgical complex Bor (RTB) exploits sulphide copper ores, thus emitting acid sulphur gases and suspended particles with high content of Cu, Zn,...

In this paper, we propose a methodology for the characterization of the suspended particulate matter along the Algiers’s bay. An approach by multi-layer perceptron (MLP) with training by back propagation of the gradient optimized by the algorithm of Levenberg-Marquardt (LM) is used. The accent was put on the choice of the components of the base of training where a comparative study made for fou...

background: the aim of study was to measure particle matter concentration (pm 1, pm 2.5 and pm 10 ) during normal, semi-dust and dust-event days. the impacts of some meteorological factors on particle matter concentrations were also investigated. methods: samples were collected by grimm aerosol technik (gmbh model 1/108 germany) from november 2011 to may 2012. temperature, humidity, wind speed ...
