In R&D projects performed under Dr. Hashmonay’s direction for both public and private sector clients, advanced methods have been developed and used to measure gaseous and particulate emissions from sources as diverse as landfills, concentrated animal feeding operations, wastewater treatment plants, chlor-alkali plants, refueling stations, military aircraft, fugitive dust from military activities, open burning, barges, near-road mobile sources, agricultural operations, fertilizer manufacturing plants, oil & gas production facilities, coke oven batteries, chemical manufacturing plants and many locations and process units within petroleum refineries. These studies (performed internationally in N. America, Asia including Israel, Europe, Australia, and South America) also provided essential data for calculating emission factors for these sources. His methods have also been applied for emergency response as well as for human health and safety applications.
