CONTACTLESS ELEMENTAL AND SIZE ANALYTICAL SYSTEM FOR NANOSIZED SUSPENDED PARTICULATE MATTER USING LIBS AND LII TECHNIQUES

This paper presents a non-contact sensing system for nanosized suspended particulate matter (SPM) measurements using laser-induced incandescence (LII) and laser-induced breakdown spectroscopy (LIBS). The elemental composition and density of the SPMs are determined using LIBS, and particulate size measurements are accomplished using LII. Typically, temporally resolved LII enables measurement of soot particulate sizes in a combustion process. In the case of the measured object consisting of a single element material, it is easy to determine the particulate sizes distribution derived from the...

CHEMICAL AND MORPHOLOGICAL STUDY OF PARTICULATE MATTER ANALYSED BY SEM-EDS

PM10 samples were collected simultaneously at three representative areas (central city, industrial area and rural clean air). Their morphology and elemental composition were determined by scanning electron microscopy coupled with energy analysis (SEM-EDS). The particles were classified into groups based on morphology and elemental composition.

DEVELOPMENT OF AN ANALYTICAL METHOD FOR THE DETERMINATION OF ELEMENTS IN PARTICULATE MATTER BY MEANS OF ED-XRF

Among the analytical techniques of particular importance for the determination of the content of elements in samples of atmospheric particulates deposited on membranes there is energy dispersive X-ray fluorescence spectrometry (ED-XRF). This method combines the advantages of being rapid, non-destructive, multi-elemental, adequately sensitive and quantitative. The use of polarized radiation allows minimizing the background signal and, consequently, improves the detection limits. The elements determinable through ED-XRF are characterized by atomic number greater than 10. Those on which the...

THE USE OF A MULTIWAVELENGTH LIDAR TO DETECT AEROSOL LAYERS IN THE ATMOSPHERE

The peculiarity of lidar systems is to provide vertical profiles of aerosol extinction and backscattering coefficients, which allow getting information on aerosol optical properties and their dependence on altitude. We analyze in this paper a case study in which lidar signals have allowed detecting different atmospheric aerosol layers from the boundary layer up to the stratosphere. Results on the dependence of aerosol optical properties on altitude will also be presented.

SENSOR NETWORK FOR ENVIRONMENT MONITORING: WATER QUALITY CASE STUDY

The challenges of climate change, population growth, demographic change, urbanisation and resource depletion mean that the world’s great cities need to adapt to survive and thrive over the coming decades. Slashing greenhouse gas emissions to prevent catastrophic climate change while maintaining or increasing quality of life can be a costly and difficult process. Two factors that directly affect the life quality in the XXI century cities are the water and air quality that can be monitored using the combination of low cost sensing modules, M2M and IoT technologies. In this context the work...

RAMAN PROBE OF POLLUTANTS IN WATER: MEASUREMENT PROCESS

Raman probe can be used to detect substances dissolved in water. Here are reported and discussed some experimental and data treatment processes needed to identify species and also to determine their content in a mixture. A particular attention is paid to the treatment of Raman line intensity used in the calibration of the probe.

WATER POLLUTION DETECTION

Human activities are, more or less directly, responsible of the increasing pollution in running waters, making their pollution an important issue over the last decades and the ones to come. Many documents define a legal frame on the water pollutants (classifying them depending on their toxicity, environmental impacts or origin), thus underlying the importance of the surveillance of their presence in the environment. The difficulty for the surveillance of these products is the great diversity of pollutant families, leading to the necessity to use several analytical techniques. This paper...

ASPECTS ABOUT AIR POLLUTION PREDICTION ON URBAN ENVIRONMENT

This paper focuses on the processing of experimentally measured pollution data. Since estimating air pollutant can have significant economic impact already on a short term basis as well as relevant consequences on public health on a medium-long term scale, various interdisciplinary researches are under way on this subject. In this work, we pursue two goals: the former is to derive a representative model of the multivariate relationships that should be able to reproduce local interactions; the latter is to predict, when possible, the short term evolution of pollutants in order to prevent the...

SIZE-DISTRIBUTIONS OF WATER SOLUBLE COMPONENTS OF ATMOSPHERIC AEROSOL MEASURED WITH A MOUDI IMPACTOR

Understanding climate and health effects of atmospheric aerosol is an important aspect of research. These effects are strongly related to the size-distribution of particles and of chemical components contained in aerosol. In this work aerosol was collected, in an urban background site in Lecce, using a 10-stages Micro-Orifice Uniform Deposit Impactor (MOUDI). Collected samples were analysed to evaluate the size-segregated composition of water soluble ions (Ca 2+ , Mg 2+ , K + , NH 4 + , Na + , SO 4 2- , NO3 - and Cl - ), using High Performance Ion Chromatography (HPIC), and of water soluble...

REAL TIME MONITORING OF URBAN PARTICULATE MATTER ON A MOBILE PLATFORM

The project main focus is the study of urban pollution dynamics, with a particular attention to vehicular traffic and generated aerosols. Techniques at work include fast pollutants and micrometeorology monitoring from both fixed and mobile stations as well as advanced statistical treatments of the data. Communication and dissemination of the results is also an important task of the project. The audience includes government policy-makers, media, environmental and health professionals, healthcare providers, the public, and vulnerable populations.
