Fig. 1 Physiological responses in brown trout exposed to road runoff ( filled bars ) and stream
water ( hatched bars ) for 24 h (mean ± S.E. n = 2-6). Metals in gill tissue expressed in µg/g dw,
glucose, sodium, chloride and HCO 3 expressed in mmol/L, TCO 2 and pCO 2 expressed in mmHg,
hematocrit and SOD inhibition rate expressed in %, CAT expressed in µM/min mg/protein and
MT in nmol/g ww. Bars with a different letter represent a significant difference (p < 0.05). SW
