Measurement of Water Quality in Tomorrow’s Agroecosystem

November 23 @ 11:00 am - 12:00 pm

Agriculturally-intensive watersheds support some of the most productive land and highly stressed aquatic ecosystems in the world today. Recent reports summarizing changes in water quality increasingly identify contaminants in streams, reservoirs and groundwater with most significant changes occurring in heavily agricultural areas. Advances in food crop, livestock and biofuel production have clearly increased agricultural productivity, though with trade-offs to water quality and aquatic ecosystem services. Many chemicals used in agriculture and livestock production, including veterinary pharmaceuticals, antibiotics, and
steroid hormones are released to the environment from multiple sources. These chemicals of emerging concern (CEC) can be released through recycled, drainage, or runoff water used for irrigation and many may pose environmental, human health, and/or food safety concerns. Though many measures of water quality may be considered robust and highly standardized, accurate and consistent measurement of these CECs is far from simple and routine. Measurement of these compounds in various environmental compartments have uncovered a previously unrealized landscape of organic residues with potential effects to
ecosystem function and human health. This presentation will more shed light on passive sampling as one of the innovative method for in-situ sampling and concentrating CECs for their detection.Discipline/Coordinating Entity: Earth Science
