Concentrations are reported of hexabromocyclododecanes (HBCDs) and tetrabromobisphenol-A (TBBP-A) in water (n ) 27), sediment (n ) 9), and fish samples (n ) 30) from nine English lakes. Seasonal variation in concentrations in water is minimal. Concentrations of TBBP-A range from 140 to 3200 pg L-1 (water), 330 to 3800 pg g-1 dry weight (sediment), and
