The Cornell Chemical Ecology Core Facility (CCECF) expanded its services over the past year, analyzing more than 2,500 samples from 43 clients, including beekeepers, NGOs, university researchers, and government researchers. The facility analyzed bees, pollen, wax, propolis, soils, leaves, fruits, silicone bands, and bird blood for pesticide residues. Additionally, the CCECF completely overhauled its multi-residue pesticide method, making it more sensitive and broadening its target range. The revamped method now quantifies 102 pesticides, with most detection limits below 1 part per billion (ppb).
