Trace Metal and Pesticide Exposure in Tree Planting in British Columbia
Concerns about the health effects of occupational exposure to fertilizers have been raised by both tree planters and contractors. Fertilizers, which sometimes contain heavy metal contaminants, are often applied at the same time that tree seedlings are planted. Some seedlings are also treated with chemical insecticides and fungicides in the nurseries, and it is possible that there could be pesticide residues on the seedlings when they are being planted. The purpose of this study was to examine these potential exposures and to investigate potentially related health effects.
