This paper examines the spatial point pattern of industrial toxic substances and the associated environmental justice implications in the San Francisco Bay Area, California, USA. Using a spatial analysis method called Ripley's K we assess environmental justice across multiple spatial scales, and we verify and quantify the West Oakland neighborhood as an environmental justice site as designated ...

AERMOD is an advanced plume model that incorporates updated treatments of the boundary layer theory, understanding of turbulence and dispersion, and includes handling of terrain 1 On assignment to the National Exposure Research Laboratory, U.S. Environmental Protection Agency. interactions. This paper includes an overview of AERM:OD's features relative to ISCST3, a dispersion model that is wide...

Particulate matter (PM) sampling of cotton harvesting operations at three locations in Texas was conducted during the summer of 2006. PM emissions generated by a two-row (John Deere model 9910) and six-row (John Deere model 9996) cotton picker were measured at each sampling location. The PM emissions from the two-row and sixrow machines were measured using a protocol employing collocated low vo...

Geographic information system (GIS) based emission inventory of particulate matter of aerodynamic diameter less than 10 μm (PM10) for the base, 5 th and 10 th year was developed for Kanpur, an urban area in India. It has been observed that the 5 th and 10 th year will experience increased emission by factors of 1.5 and 2.2 of the base year. Twenty one control options (e.g. introduction of Euro ...
