Air Particulate Monitoring – PM1
What is PM1 “PM” (Particulate Matter) is not a single pollutant but refers to a complex mixture of solids and aerosols. Which are of varying shape, size, and chemical composition. Which may contain many chemical species like organic compounds, inorganic ios, metallic compounds, elementary carbon, etc. These atmospheric particles are definable by their diameter for air quality ...

Using the exhaled breath condensate as a tool for non-invasive evaluation of pollutant exposure
The aim of the present study was to investigate whether Exhaled Breath Condensate (EBC) can be employed for a better risk assessment among human exposure to heavy metals. The objective was to develop a human bioindicator to be applicable for professional exposure that, compared with other common indicators, presents important advantages: it is non-invasive and it is easily and quickly collected. ...

Inter-comparison of predicted population exposure distributions during four selected episodes in Helsinki and evaluation against measured data
Air pollution causes significant excess mortality and health effects. Action plans required by the EU legislation should optimally account for the complex interactions of population distributions, time-activity and the sources of air pollution. This paper presents FUMAPEX study results on probabilistic exposure modelling for evaluation of population exposure distributions during selected episodes ...

Seasonal variation in suspended particulate matter vis-a-vis meteorological parameters at Kolar Gold Fields, India
Particulate matter concentrations and meteorological parameters were monitored to assess the impact of other industries likely to be set up at Kolar Gold Fields, India. Particulate matter less than 10 µm was the highest in winter due to the influence of gold mill tailings dumps while total suspended particulate matter was generally higher in spring probably due to the influence of uncovered area ...

Investigation of indoor/outdoor air pollutants at the shopping malls in Wuhan
Indoor air quality was investigated at eight shopping malls in Wuhan. Results demonstrate that there are different concentrations of CO2 and HCHO at different floors of a shopping mall. Even at different merchandise zones of a floor for the same mall, there are apparent variations in the concentrations of CO2 and HCHO. These findings should be considered in designing air-conditioning systems. The ...

Predicting air quality in Uberlandia, Brazil, using linear models and Neural Networks
Particulate air pollution causes a wide range of effects on human health, including disorders of the respiratory and cardiovascular systems, asthma and can cause mortality. Hence, the development of an efficient air quality forecasting and early warning system is an obvious and imperative need. The objective of this work was to investigate this forecasting possibility using linear models (such as ...

Dust monitoring with ProSens on clean gas side - Case Study
Application An international mining company extracts minerals under ground for the fabrication of fertilizers. For the long term improvement and safety of the structure stability fi llings and binders (dry bulks) with defi ned recipes are injected locally into former mining cavities. These materials are delivered above ground, stored in silos and afterwards transported in a closed-pipe ...

Airborne chemical elements: correlation between atmospheric levels and lichen content
Concentrations of As, Cd, Co, Na, Sb, Se and Zn have been measured in atmospheric particulate matter and Parmelia sulcata Taylor transplants at a suburban and industrial area. Levels in particulate matter were found to be much lower than European target values, Californian Acute Inhalation Reference Exposure Levels and Ontario's Ambient Air Quality Criteria. Correlations between elemental content ...

Winter time particulate matter concentrations at an urban roadway in India
This paper presents analysis and interpretation of 1-hr average fine (PM 1 and PM 2.5 ) and coarse (PM 10 ) particulate matter (PM) concentrations measured during winter 2008 and 2009 at a roadside in Chennai city, India. Results showed typical weekly and diurnal cycles with high concentrations corresponding morning and evening peak traffic flows. The 24-hr average PM 10 and PM 2.5 ...

Trends of lead in suspended particulate matter in Zagreb air
Monitoring of lead in Total Suspended Particulate Matter (TSPM) started in Zagreb, Croatia in 1971 at three measuring sites. Monitoring of lead concentrations in PM10 started in 1999. This paper presents the trends of annual mean values for lead concentrations in TSPM and in PM10 particles. The obtained data showed a decreasing trend of lead in TSPM, especially during the last ten years when the ...

A methodological proposal for the identification of energy-environmental performance indicators aimed at recovering the air quality
The paper deals with the introduction of a complex index capable of evaluating environmental air quality in industrial areas. In Italy regional plans of recovery and protection of air quality have been put in practice in order to identify areas where the increase of the emissions into atmosphere, owing to urban and/or industrial development, should be limited or prevented. The methodology is ...

Mesoscale controls on particulate matter pollution for a mega city in a semi-arid mountainous environment: Tehran, Iran
Tehran, the mega-city capital of Iran, suffers from high concentrations of PM10 throughout the year. Emissions from transport combined with mesoscale atmospheric features related to the mountainous terrain lead to a distinctive diurnal pattern in concentrations. Air quality data from monitoring stations show that the highest concentrations of PM10 are in the morning and evening periods, ...

Impact of meteorological modelling on air quality: summer and winter episodes in the Po valley (Northern Italy)
The Po–valley in Northern Italy has been identified as a hot spot area in Europe where pollutant levels are expected to remain problematic in the years to come. High anthropogenic emissions in combination with frequently occurring stagnant atmospheric conditions cause very high concentrations of pollutants. Sensitivity tests for one winter month have shown that the nudging of observational data ...
