tailieunhanh - Air Pollution Sampling and Analysis (Laboratory Manual)

Some results of indoor particulate (PM) concentrations measurements in relation to type of stove and fuel from Latin-America are presented in table . The improved stoves, such as the plancha, produce PM or PM levels that are often only 20 percent of concentration levels from an open fire, and are even found to be less than 10 percent of that of an open fire in a study in Guatemala by McCracken and Smith (1998). The reduction in PM seems to be even larger than reductions in PM 10. However the concentration levels. | I IJ Office of the Coordinator I r CURRICULUM DEVELOPMENT PROGRAMME dual ity I m provemc nt Prog rani me Indian Institute of Te oh n o logv G LI wa 11 ati Air Pollution Sampling and Analysis Laboratory Manual Dr. Sharad Gokhale sharadbg@ Department of Civil Engineering Indian Institute of Technology Guwahati Guwahati - 781039 Assam India Date May 2009 Developed under the Curriculum Development Scheme of Quality Improvement Programme at IIT Guuvahati Spun sored by All India Council dfTEctinica Education lAiCTE Laboratory Manual of Air Pollution Sampling and Analysis This laboratory manual is useful to environmental engineers scientists undergraduate and graduate students chemists and environmental field engineers.
