Environmental impact assessment (EIA) and environmental management plan (EMP) is a statutory requirement for execution of new mining projects or for expansion of the operating projects. For this purpo...
Particle number, particle mass and NOx emission factors at a highway and an urban street in Copenhagen
Particle number particle mass NOx emission factors an urban street Copenhagen
2010/8/12
This paper presents measurements of traffic-generated gas and particle pollution at two sites, one near a major highway and one near a busy urban street in Copenhagen, Denmark. Both sites were equippe...
Biomass burning aerosol emissions from vegetation fires: particle number and mass emission factors and size distributions
Biomass burning aerosol vegetation fires mass emission factors
2010/2/21
Aerosol emissions from vegetation fires have a large impact on air quality and climate. In this study, we use published experimental data and different fitting procedures to derive dynamic particle nu...
不同地面结构的育肥猪舍NH3排放系数（NH3 Emission Factors of Fattening Pig Buildings with Different Floor Systems）
育肥猪舍 氨气 排放系数
2010/1/28
NH3排放系数是对规模化养殖场NH3排放量估算、NH3减排方法与技术应用效果评估的有效方法之一。通过在模拟实际生产动物人工气候室对3种不同地面结构的育肥猪舍NH3排放相关数据的连续在线检测，研究了不同地面类型猪舍内NH3排放与主要影响因子的相关性及其排放系数。研究得出半缝隙地面猪舍、实心地面猪舍、生物发酵床猪舍内NH3排放系数分别为：(9.47±7.09)、(11.23±4.23)、(4.27±2...

2009/5/7
Atmospheric particle number size distributions of airborne particles (diameter range 10–500 nm) were collected over ten weeks at three sites in the vicinity of the A100 urban motorway in Berlin, Germa...
Emission Factors for Combustion of Biomass Fuels in the Pulp and Paper Mills
CO2 cycle CO2 neutral neutral biomass black liquor bark wood rejects BFB
2009/2/7
As one of the biggest wood consumers, pulp and paper mills are full participants in the C⇒CO2⇒C cycle. Thanks to the production of climate-neutral biomass fuels recovered from pulping (inc...
Aerosol and NOx emission factors and submicron particle number size distributions in two road tunnels with different traffic regimes
NOx emission factors submicron particle size distributions different traffic regimes
2009/1/9
Measurements of aerosol particle number size distributions (18–700 nm), mass concentrations (PM2.5 and PM10) and NOx were performed in the Plabutsch tunnel, Austria, and in the Kingsway tunnel, Unite...
Seasonal variability of monoterpene emission factors for a ponderosa pine plantation in California
Seasonal variability monoterpene emission factors ponderosa pine plantation California
2009/1/6
Monoterpene fluxes have been measured over an 11 month period from June 2003 to April 2004. During all seasons ambient air temperature was the environmental factor most closely related to the measured...
