Monitoring chronic ethylene gas levels throughout the horticultural industry.

In a project to improve the shelf-life and quality of horticultural crops, 1700 air samples were taken from September 1998 to February 1999 at twenty operations handling horticultural products, all within a 100 km radius of Vineland, Ontario, Canada. The operations included growers, wholesalers, retailers and processors of fruits, vegetables and flowers. Almost 2/3 of the air samples contained ethylene gas (C2H4) in various levels from non-detectable to 133 parts per million. 9 operations had ethylene present in over 65% of their samples, while 11 operations had maximum levels recorded of over 1 ppm. It was apparent that eliminating ethylene from all sites is impractical, but most of the operations had some options available for reducing these levels, and several planned on making changes as a result of the survey. The 50 people at the operations involved now have a greater awareness of the role ethylene plays in the post-harvest handling of fruits, vegetables and flowers.
