Refining Area Source Emission Factors:  Lessons Learned from Agricultural Fumigant Flux Studies

Sullivan Environmental has conducted over 50 studies to analyze the emission rates of agricultural fumigants over time.  The majority of the studies were done with our partner laboratory Ajwa Labs.

These studies focus on fumigant application and subsequent off-gassing. This research has provided valuable insights into refining emissions factors, including emission factors for area sources. It has broader implications for understanding other complex sources of air pollutants.

What is an agricultural fumigant? Agricultural fumigants produce quality food products.  These substances, applied as a liquid or gas and injected into the soil before planting, help young crops grow by suppressing weeds, diseases, and nematodes—tiny creatures that can harm roots.

Before planting, fumigants are injected into the soil.  They create an environment that supports the growth of young crops by suppressing weeds, diseases, and nematodes—small, worm-like creatures that can damage tender roots.

Sullivan Environmental has likely participated in more agricultural fumigation studies than any other company in the United States.  These studies have involved sampling tens of thousands of air samples for regulatory review.  The lessons learned from agricultural fumigation studies involve developing innovative equipment and methods to collect samples in large-scale studies.  This consists of collecting up to 40 samples simultaneously using solar-powered air sampling pump enclosures. 

This innovation allowed the Sullivan Environmental staff to revolutionize the air sampling of large studies using extremely experienced staff and less labor. This allowed Sullivan Environmental to complete better research using fewer people with advanced equipment. This innovation in air quality consulting methods allowed Sullivan Environmental to conduct most regulatory fumigation flux studies in the United States.  

Our methods, staffing, and equipment are the best in the business.  We can meet your needs if you register a fumigant or need fumigation flux studies for experimental testing.
