Phytotoxicology Section investigation in the vicinity of Suncor
Ltd., Sarnia, on September 6, 1990.
Ontario.
Air Resources Branch, Toronto.
Report
no. ARB-072-91-PHYTO. |
The Alkylation
Unit at the Suncor refinery in Sarnia produces a hydrocarbon
waste product that contains organic and inorganic fluoride material
whose burning produces emissions of fluoride to the atmosphere.
Two assessment surveys were conducted in 1986 and 1987 in the
vicinity of the refinery to determine if fluoride emissions
were affecting vegetation. Both surveys
showed marginally elevated levels of fluoride at some sites,
but the pattern of accumulation and the amount of fluoride did
not agree with the model. The assessment survey was repeated
in September 1990 to confirm the results of the first two surveys.
This report presents the results of the 1990 survey. |

On 19 August
1991, a phytotoxicology survey was conducted in the vicinity
of the new production facility of Brampton Brick near Snelgrove,
Ontario. The new facility opened in 1988
but did not become fully operational until 1989. A pre-operational
study was conducted in 1987, followed by post-operational (fluoride)
surveys in 1989 and 1990. The August 1991 survey used foliage
collected from the exposed side of the seven maple tree sites
established in 1990. Forage collection was discontinued at the
six forage sites sampled in previous years. From each maple
site, duplicate samples of foliage were collected using standard
sampling procedures. In addition to foliage sampling, maple
trees and other vegetation growing in the survey area were inspected
for foliar fluoride injury. |

On 30 August
1990, a vegetation survey was conducted at established sites
in the vicinity of the American Standard
plant in Cambridge, Ontario. Vegetation at 17 sites initially
established in 1989 was examined in 1990 for evidence of injury
and sampled for chemical analysis. Three new sites west and
northwest of the plant were added for the 1990 survey. At each
site, either silver maple, Norway maple or both were used for
observational and sampling purposes. Vegetation at each site
was examined for air pollution injury symptoms and injury severity
ratings and the percentage of injured foliage at each site.
Following the observational phase, and depending on availability,
silver, Norway or amur maple foliage was collected in duplicate
for chemical analysis. The foliage samples
were analyzed for boron, fluoride,
barium, titanium, sodium, nickel, zinc, lead, magnesium, copper,
sulphur and iron. This report provides the results of the analysis. |

Since 1976,
regular vegetation surveillance investigations have been conducted
in the vicinity of Morterm Ltd. in Windsor, Ontario
to determine the impact of fluoride on the environment. Morterm
is a port terminal on the Detroit River which handles a variety
of commodities, including bulk fluorspar. Approximately
1.5 km south of Morterm, the Canadian Salt Co. Ltd. operates
a salt mining facility. Although no formal survey was conducted
around the salt facility, grasses collected as part of the Morterm
survey since 1979 have been analyzed to determine concentrations
of sodium and chloride. Prior to the 1989 field season, an official
request was received to conduct a more comprehensive surveillance
of vegetation and soil in the vicinity of the salt mine. On
19 September 1989, a grass and soil surveillance incorporating
both Morterm Ltd. and the Canadian Salt Co. Ltd. was conducted

Morterm
Ltd. of Windsor is a port facility on the Detroit River that
handles a variety of commodities, one of which is bulk fluorspar
(calcium fluoride).
It is unloaded and stored in bulk piles which are supposed be
wetted down, as the material consists of very fine particles
which can be blown away by light winds. Since 1976, surveys
of grasses have been conducted at 10 sites near the property
to monitor fluoride concentrations. About 1.5 km south of Morterm
is the Canadian Rock Salt Co., which extracts salt from a mine
on the property and stores it in large open piles before shipment.
In 1985, another site was added to the survey and in 1989, six
more sites were added to cover both Morterm and the Canadian
Rock Salt Co. In 1989, triplicate samples of grasses were collected
for chemical analysis and 0-5 cm soils were collected at 14
of the 17 sites. Grass and soil samples
were analyzed for fluoride, calcium, sodium, and chloride determinations.

Report
no. ARB-033-90-PHYTO. |
Vegetation
assessment surveys have been conducted since the early 1970s
in the vicinity of the Canadian Industries Ltd. (CIL) Lambton
Works superphosphate operation because
of substantial emissions of hydrogen fluoride (HF) from the
manufacture of superphosphate fertilizer, from the open stack
of gypsum wastes, and as a result of evaporation from two settling
ponds east of the plant. CIL capped the large stack of
gypsum waste material with several feet of clay, eliminating
fluoride emissions from this source. In addition, about 350
million of the 500 million gallons of liquid in the settling
ponds were treated to remove phosphates and fluorides and a
further 100 million gallons are being treated. In 1989, a vegetation
assessment survey examined silver maple species at each of 9
sites in the vicinity of the CIL plant. At a further 10 sites,
grasses only were examined. This report presents the results
of the survey. |

As a result
of a vegetation complaint investigation conducted in 1988, it
was suspected that the American-Standard
plant was a source of boron and fluoride emissions. Foliage
and soil was analyzed and showed elevated levels of boron. A
visual survey was also conducted, showing the same damage. On
August 31 and September 6, 1989 a survey was conducted at 18
sites in the vicinity of the plant to assess the character,
magnitude and extent of pollution effects on vegetation and
soils. At each site, vegetation was examined for air pollution
injury symptoms and observations were recorded. Injury severity
ratings and percentage of injured leaves on plants were the
main parameters assessed. Following this, Norway maple or silver
maple foliage was collected for chemical analysis. A visual
analysis was also conducted. This report presents the results

A
literature review was conducted of the acute toxicity of hydrogen
fluoride (HF) with emphasis on the effects of inhalation of
gaseous HF.
The data and findings of the relevant references were summarized
under four categories: animal studies, controlled human studies,
community exposure and industrial exposure. These were critically
reviewed and then lethal concentration-time relationships were
developed for humans, corresponding to LCsub(LO), LCsub(10)
and LCsub(50) levels. The effects of age, health and other physiological
