Emission inventories are databases that aim to describe the polluting activities that occur across a certain geographic domain. According to the spatial scale, the availability of information will vary as well as the applied assumptions, which will strongly influence its quality, accuracy and representativeness. This study compared and contrasted two emission inventories describing the Greater ...

Volatile organic compounds (VOCs) were measured by two online instruments (GC-FID/MS and PTR-MS) at a receptor site on Changdao Island (37.99 N, 120.70 E) in eastern China. Reaction with OH radical dominated chemical losses of most VOC species during the Changdao campaign. A photochemical-age-based parameterization method is used to calculate VOC emission ratios and to quantify the evolution of...

Purpose: Managing the inventory of spare parts is very difficult because stochastic nature part’s demand. Also, only controlling part not enough; instead, supply chain needs to be managed efficiently. Moreover, every organization now aims have a resilient and sustainable overcome risk facility disruption ensure environmental sustainability. This paper thus establish model inventory-location rel...

This presentation will touch on four aspects of California's reactivity program. First, it will cover ARB's existing Low Emission Vehicle/Clean Fuels regulation and a consumer products regulation which is under development. Second, it will provide a very brief summary of some of the research the California Air Resources Board (ARB) is currently funding in the field of reactivity. Lastly, it wil...

We present maps of dust emission at 7μm and 15μm/7μm intensity ratios of selected regions in 43 spiral galaxies observed with ISOCAM. This atlas is a complement to studies based on these observations, dealing with star formation in centers of barred galaxies and in spiral disks. It is accompanied by a detailed description of data reduction and an inventory of generic morphological properties in...

The time course of isocyanate emission from curing PUR-adhesives was studied in an emission test chamber. The adhesives under investigation were commercial products for fixing of textile floor coverings and based on methylene bisphenyl diisocyanate (MDI). Influence of the curing mechanism was studied by comparing the emission curves of one-component adhesive (OCA) and two-component adhesive (TC...

Ammonia emissions from swine feeding operations depend on the housing type; animal size, age, and type; manure management, storage, and treatment; climatic variables; and manure utilization or land application techniques. Techniques or methods for estimating or quantifying NH3 flux from a source to the atmosphere include nitrogen mass balance, micrometeorology, flux chambers, models, and emissi...

Methods for ranking photochemical ozone formation reactivities of volatile organic compounds (VOCs) are discussed. Photochemical mechanisms for the atmospheric reactions of 118 VOCs were used to calculate their effects on ozone formation under various NOx conditions in model scenarios representing 39 different urban areas. Their effects on ozone were used to derive 18 different ozone reactivity...
