Emerging environmental contaminants (EECs, e.g., perfluoroalkyl and polyfluoroalkyl substances [PFAS], heavy metals, trace elements, harmful algal bloom products, and micro- and nano-plastics) can impact drinking water and water used for irrigation of food crops. In fact, previous research has shown irrigation water containing EECs can be absorbed into food crops (i.e., produce and grain, meat, and dairy) which is then consumed by humans and animals. The consumption can negatively impacting health and should be of concern. However, little is known about perceived risks associated with plastic use on farm. The Lamm Lab team including Emily Dustman, Kristin Gibson, Olivia Erskine, and Dr. Alexa Lamm in collaboration with Dr. Jim Owen, USDA ARS, Dr. Sarah White, Clemson University, and Dr. James Altland, USDA ARS sought to determine what nursery and greenhouse growers, scientists and water regulators thought about plastic use on farm and its contribution to water contaminants. Preferences for how to communicate water-related information were also examined.
Early findings from the mixed methods studies including a survey and focus groups were shared in Atlanta, GA to a room full of scientists and graduate students interested in advancing the field of ornamental horticulture production at the Annual Southern Region meeting for the American Society for Horticultural Sciences. Similarities and differences in perceptions between scientists and regulators were discussed as well as how producers articulated their use of plastics on-farm and how they ensure environmental sustainability through their water remediation and recycling practices. The research project was funded by USDA ARS Cooperative Agreement Number 58-5082-3-021.
The Southern Region meeting of the American Society for Horticultural Sciences was part of the Southern Association of Agricultural Sciences (SAAS) convergence of research from several disciplines. Members of the Lamm Lab also participated in other sections including the Southern Region American Association for Agricultural Education conference, the annual meeting of the Southern Rural Sociological Association, and the National Agricultural Communications Symposium.
