Abstract

cadmium forest ecosystems treated municipal waste water
Treated municipal waste water was irrigated in an abandoned old field area from 1964-1974 and in a mixed hardwood area (old gamelands) from 1964-1974. Total applications of Cd in the old field and old gamelands areas were 0.47 and 0.61 kg/ha, respectively. White spruce (Picea glauca Moench Voss.) and wild strawberry (Fragaria virginiana Duchesne) foliage sampled from the old field showed no increase in Cd concentrations due to effluent irrigation, while goldenrod (Solidago sp. Ait.) had lower Cd levels in the treated area than in the unirrigated control area. Foliage sampled from red maple (Acer rubrum L.), white oak (Quercus alba L.) and wild sarsaparilla (Aralia nudicaulis L.) in the old gamelands, showed no increase in Cd as a result of waste water irrigation. Soil Cd levels were not significantly affected by waste water irrigation in either area, except for the increase in soil Cd in the 0.5 cm depth of the old gamelands. The Cd/Zn ratios of the vegetation foliage were not significantly different between the treated and control areas.
