Abstract
This synoptic study evaluates water chemistry in stump-harvested and conventionally logged reference areas, located in South-Central Sweden, 20-30 years after harvest and reforestation. Electrical conductivity, pH, alkalinity (HCO3-), nitrate nitrogen (NO3-) and total organic carbon (TOC) were measured in discharging groundwaters and in low-order streams and ditches. The groundwaters were further analysed for total mercury (THg) and methyl mercury (MeHg). Additionally, solid phase Hgtot and MeHg were measured in stream mudbottoms. The mean MeHg concentration and mean MeHg/TOC ratio were significantly (p
