  • Microscopic Particulate Analysis

    Introduction In 1989 the EPA promulgated the Surface Water Treatment Rule (SWTR) in response to the 1986 Amendments to the Safe Drinking Water Act (SDWA). The overall goal of the SWTR is to protect consumers from pathogens. The SWTR recommends a multiple-barrier approach including source water protection, filtration and disinfection when surface water is used as source water for drinking. ...

  • Experimental Assessment of Particulate Measurement Instrumentation

     Introduction The European Commission has funded a project called 'Experimental assessment of particulate measurement instrumentation'. The project was undertaken by AEA Technology in the United Kingdom. The work comprised two phases: Phase 1: Literature review to help formulate the recommendations for measuring techniques to be investigated in Phase 2. ...

  • Characteristic study of particulates and metallic elements at an urban sampling site in Taichung, central Taiwan

    Atmospheric total suspended particulate concentrations and metallic element concentrations were measured at three locations, characteristic of urban, suburban and rural sites. The sampling period was from July 2000 to August 2000. The results indicated that the urban sampling site had the highest total suspended particulate concentrations (average 108.61µ1m³), followed by the suburban site ...

  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Sources of particulate matter: emission profile of biomass burning

    Biomass burning is an important source of atmospheric Particulate Matter (PM) in Brazil: the burning of forests in the northwest and of sugar cane plantations in the southeast are important examples. The objective of this work is the measurement of the PM emission profile of burning of sugar cane and other characteristic vegetative burning in the region of Sao Carlos-SP/Brazil. Samples of PM10 ...

  • Suspended Particulate Matter Definition - SPM and RSPM

    There is much confusion about how to define PM10 particulate, but if articles indicate the definitions they used then the information can be compared with information from other studies. A concern is that the dust measurement equipment for PM10 particulate matter might not be designed to meet the same defined standard as used in the articles which could lead to some discrepancies. ...

  • Assessment of particulates in the urban atmosphere of Sao Carlos, Brazil

    A survey on the concentration of particulate matter in the urban atmosphere was carried out in the city of Sao Carlos, Brazil. Five sites were selected for data collection one in the city centre (high concentration of people and automotive vehicles), three in industrial areas, and one at the interface with the countryside. The particle size distribution and mass concentration, temperature, ...

  • Element patterns for particulate matter in stormwater effluent

    Particulate matter in stormwater deteriorates the quality of receiving water and sediment. Characterization of stormwater particulate matter by means of its particle-associated element pattern provides an aid to determining its impact on receiving surface waters. During a 6 month measurement campaign, we determined particle-associated concentrations of major pollutants and rare earths for three ...

  • Ambient Air Sampling Methods

    Pollutants are nothing but any substance that may present in an atmosphere in such a concentration that it may harmful to surrounding, living organism or human being. Sampling and analysis of air pollutants is known as Air quality monitoring and it is major part of environmental monitoring. There are many advanced types of ambient air Sampling methods. we will learn here only which are most ...

  • A study of polycyclic aromatic hydrocarbons in airborne particulate matter in central Taiwan

    Two sampling sites in central Taiwan, at Hungkuang University (HKU) and Tunghai University (THU), were chosen to contrast the content of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere from November 2000 to April 2001. PAHs that arise from incomplete combustion of organic materials, especially fossil fuels, are the major toxic pollutants in central Taiwan. This study aimed to analyse ...

  • Roadside particulate levels at 30 locations in the Kathmandu Valley, Nepal

    Roadside particulate levels (PM10) at 30 locations throughout the Kathmandu Valley, Nepal are reported. There were seven sampling cycles from January to December 1999. PM10 levels ranged between 1000 and 6000 µ/m³ for 1-h sampling. There was no consistent trend in PM10 levels with respect to monitoring cycle, average precipitation or wind speed. There is no WHO ...

  • Short-term variations in ambient particulates and their sources in Taichung, Taiwan

    Ambient particulate measurements were carried out using TE-PUF sampling and a Universal Air Sampler between 8 March and 25 April 2001 at Taichung. Samples were collected every 6 hours beginning at 0100 LST (Local Standard Time) each day at two sites, one at a university campus and the other at a roadside. Chemical species (Cl-, NO3-, ...

  • Coarse particulate matter apportionment around a steel smelter plant

    The results from a study carried out in the urban area of Genoa, Italy, where a large steel smelter recently shut down are presented. We had the opportunity to sample particulate matter (PM) before and after plant closure and, therefore, to measure the changes in concentration and composition of PM10 (atmospheric PM with aerodynamic diameter  10  m). Elemental concentrations of Na to Pb were ...

    The gaseous and nonvolatile particulate matter (PM) emissions of two T56-A-15 turboprop engines of a C-130H aircraft stationed at the 123rd Airlift Wing in the Kentucky Air National Guard were characterized. The emissions campaign supports the Strategic Environmental Research and Development Program (SERDP) project WP-1401 to determine emissions factors from military aircraft. The purpose of the ...

  • Thermal Desorption-GC/MS Analysis of polycyclic aromatic hydrocarbons on fine particulates in air

    Polycyclic aromatic hydrocarbons (PAHs) are commonly found throughout the environment in soil, water and adsorbed to fine particulate matter in air. Of the 16 common PAHs, 7 have been classified as animal carcinogens by the International Agency for Research on Cancer (IARC). Resulting from this classification, PAHs are monitored and regulated in the environment. Analysis of PAHs in soil and water ...
