Validation of Ogawa passive samplers for the determination of gaseous ammonia concentrations in agricultural settings
The Ogawa passive sampler (Ogawa USA, Pompano Beach, Florida) is a useful tool for monitoring atmospheric ammonia (NH3(g)) concentrations and assessing the effects of agricultural waste management practices on NH3(g) emissions. The Ogawa sampler, with filter-discs impregnated with citric acid, was used to trap and determine NH3(g) concentrations in a variety of agricultural settings. A wide ran...
متن کاملFinal Report Improving Model Estimates of Smoke Contributions to Regional Haze Using Low-cost Sampler Systems
Robust low-cost sampler systems allowing for monitoring of air pollutants important for air quality resulting from forest fires and urban/agricultural activities in remote locations were tested and developed. The main emphasis was placed on passive samplers for ozone and nitrogenous pollutants (nitrogen oxides, ammonia and nitric acid vapor). In addition, a system for evaluation of total inputs...
متن کاملBaseline ambient gaseous ammonia concentrations in the Four Corners area and eastern Oklahoma, USA.
Ambient ammonia monitoring using Ogawa passive samplers was conducted in the Four Corners area and eastern Oklahoma, USA during 2007. The resulting data will be useful in the multipollutant management of ozone, nitrogen oxides, and visibility (atmospheric regional haze) in the Four Corners area, an area with growing oil/gas production and increasing coal-based power plant construction. The pass...
متن کاملAssessment of sorbent impregnated PUF disks (SIPs) for long-term sampling of legacy POPs.
Two field studies were conducted for one year using sorbent-impregnated polyurethane foam (SIP) disks for PCB and PBDE air sampling. SIP disks were introduced by Shoeib et al. (2008) as an alternative passive air sampling medium to the polyurethane foam (PUF) disk and have the advantage of a higher holding capacity for organic chemicals. The first study on SIP disks confirmed their application ...
متن کاملA Passive Sampler for Atmospheric Particles
Preliminary investigation on the feasibility of size selective passive sampling for atmospheric particles was undertaken through laboratory simulated and outdoor sampling. The passive samplers used in the research were improved from passive sampler used for sampling atmospheric organic contaminants. Sampled particle size distribution was analyzed by MasterSizer 2000 laser particle size analyzer...
