  1. aFilled circle means chemical first appeared on take-home questionnaire; no circle means chemical first appeared on follow-up questionnaires (Phase 2/3)
  2. bRange of years presented for pesticides with evidence of use prior to established registration year; for duration of market availability calculations, the lower bound of years was used (for those with a range) and rounding to a 5- or 10-year increment was calculated occurred if it fell 1 year short of this increment
  3. cPlausible responses were those where total years reported were ≤ number of years calculated between Phase 3 completion year (2005–2010) and the official pesticide registration date
