To better understand the impact of warming on heavy metals (HM) associated with plant litter decomposition in streams, we investigated the impact of high and low HM (Cu and Zn) levels and different water temperatures (10,15 and 20  o  C) on microbial decomposition of  Typhaangustifolia L.litter and the associated extracellular enzyme activities. During a 100-day incubation, changes in litter mass losses, chemical composition (lignin and total carbohydrate), and extracellular enzyme activity were determined. The decomposition rates were accelerated by the low HM levels at 20  o  C (0.0051 day –1  at CK  vs  0.0061 day –1  at low HM levels). The negative effects of Cu and Zn on  Typha  litter decomposition were more pronounced at lower temperatures (10 and 15°C). The enhanced enzyme activities of cellulase and β-glucosidase and the higher lignin/litter weight loss and lignin/carbohydrate ratios were found at 20  o  C and low HM treatment. The enzyme activities of β-glucosidase and cellulase were positively correlated with litter mass losses at 20  o  C and low HM levels. These results suggest that a 5  o  C increase in water temperature may attenuate the inhibition of low HM level on litter decomposition.
