INVESTIGATION OF VEGETATION INJURY COMPLAINTS QUEENSTON

JUNE 8, 1972

On June 5, 1972, the Welland office of the Air Management Branch received complaints of soot fallout on vegetation from a group of residents in Queenston, Ontario. On June 8, the writer and Messrs. W.D. Mcllveen and P. Beck of the Phytotoxicology Section conducted an investigation at the properties of nine complainants in Queenston. These complainants were:

1. Mrs. N. Bellows, Princess Street,

2. Mrs. M. Chernets, Queen Street,

3. Mrs. J. Abma, Queen Street,

4. Mrs. M. Digweed, Queen Street,

5. Mrs. D. Bray, Queen and Partition Streets,

6. Mrs. B. Daly, Front and Partition Streets,

7. Mrs. Davidson, Front and Dumfries Streets,

8. Mrs. A. Huggins, Queen Street,

9. Mrs. E. Paganni , Queen and Kent Streets.

It was ascertained from the complainants that in the early hours Sunday, June 4, 1972, soot emissions from the S.S. C.W. Cadwell, which was docked at the Queenston wharf, were carried downwind and deposited during a rain on their properties. Examination of vegetation on the complainants properties revealed the presence of ink-like black blotches on the upper surfaces of foliage on all nine properties. The black deposits were not easily dislodged from the surfaces of the foliage and appeared to have been spread over the leaf surface by water droplets. Leaves held in the horizontal position tended to retain more deposit than leaves held in an erect position. Certain plant species such as lilac, rose, and yucca tended to retain more deposit than other species which may reflect a difference in the chemical properties of the leaf epidermal regions.

A survey of the affected area showed that all or part of the nine complainants' properties were affected by the soot fallout. The attached map shows that the affected area extended approximately 1500 feet south south¬west from the Queenston wharf.

Leaves collected from lilac and silver maple trees were examined in the laboratory under the microscope and found to be covered with particles of soot. Affected leaves were collected for documentary purposes and placed in the Phytotoxicology herbarium. In addition, color photographs were taken of affected plants during the investigation.

It may be concluded from this investigation that soot emissions originating from the Queenston wharf had affected vegetation on the properties of the nine complainants in Queenston. The effects were primarily superficial and should result in no economic loss.
