This report
describes the groundwater resources and quality in Manitoba,
environmental concerns relating to groundwater quality, and
the tools available for groundwater management and protection.
The first section details the regional physical hydrogeology
of Manitoba, including its hydrostratigraphic units and aquifers.
Groundwater quality concerns from natural
constituents such as uranium, fluoride, and iron, plus
anthropogenic concerns such as saline water intrusion, bacterial
contamination, and leakage from underground tanks are the subject
of the second section. The third section reviews the legal basis
for groundwater management in the province: Legislation respecting
water resources and water quality. The final two sections review
institutional and other instruments for groundwater management,
including activities of the Dept of Environment and Dept of
Natural Resources, water monitoring programs, mapping and aquifer
resource evaluation programs, and data collection programs.

Toxicity levels to humans during acute exposure to hydrogen

Author:
Halton DM
Atomic
Energy Control Board, Ottawa (Ontario). |
In March
1993, the Atomic Energy Control Board (AECB) commissioned and
update of a 1984 review on the acute toxicity of hydrogen fluoride
(HF). The study places particular emphasis
on the effects of inhalation of gaseous HF and is divided into
two main parts: a literature review and a lethal concentration
(LC) estimation. The literature review summarizes data
under four categories: animal studies, controlled human studies,
community exposure, and industrial exposure. Data in these areas
were critically reviewed for their relevance to lethal concentrations
at LC(sub LO), LC(sub 10) and LC(sub 50) levels that were derived
in the 1984 report. In the last ten years, only one relevant
animal study has been published. No new
controlled human studies were found but a community exposure
incident was reported. There were three new industrial/accidental
exposures reported since 1984. Evaluation of new data
does not change the lethal concentration estimates made in the
1984 report, but does indicate the ab [abstract truncated] |

Canadian
Environmental Protection Act Priority Substances List Assessment
Report: Inorganic Fluorides.
Environment
Canada, Ottawa
(Ontario). |
Inorganic
fluorides are used in Canada and emitted into the Canadian environment
both from anthropogenic (estimated releases of approximately
23 500 tonnes/year) and natural sources (amounts released are
not known). The main anthropogenic sources of inorganic fluorides
in Canada include phosphate fertilizer production, chemical
production, and aluminum smelting. Inorganic fluorides have
been measured in ambient air, freshwater (including groundwater),
seawater, aquatic sediments, soil, and biota throughout Canada,
as a restult of both natural and anthropogenic sources. Based
on these considerations, it has been concluded that inorganic
fluorides are entering the environment in quantities or under
conditions that may be harmful to the environment. (Copyright

Acidic
leaching of podzolic soils from the Precambrian Shield, Ontario,
Canada.
Author:
Findeis J
Ontario.
Ministry of Environment and Energy, Toronto. |
A previous
experiment involving the acid leaching of Plastic Lake B horizon
soil demonstrated that an amorphous aluminum tri-hydroxide is
the most likely source of inorganic aluminum.
It was also shown that fluoride leaching was highly dependent
upon the onset of inorganic aluminum leaching. To verify
and expand these results, two new experiments were designed
using four additional podzolic soils from Harp Lake, Turkey
Lakes, Kirkwood, and Hawkeye Lake, in addition to the original
Plastic Lake podzol. The experimental design was also modified
to permit a higher, more natural experimental pH (3 rather than
the 2 used in the first experiment). It was therefore necessary
to dramatically reduce the soil/water ratio so that statistically
significant amounts of aluminum could be removed from the bulk
soil despite the higher pH of the eluent. |

of a water bath system in the plant's spray booth area, porcelain
overspray was exhausted directly to the outside air. The overspray
contained boron, fluoride, titanium,
and other elements. The purpose of the surveys was to examine
area vegetation for visual evidence of air pollution injury
and particulate deposition, and to sample vegetation for chemical
analysis to determine the impact of emissions from the plant.
Results for 1991 are presented in comparison to those from 1989
and 1990 surveys to assess the effectiveness of the plant's
pollution abatement actions. |

Report
no. ARB-014-92-PHYTO. |
A federal-provincial
study with participation by a number of government agencies
has been ongoing on the Cornwall Island Reserve (Mohawks
of Awkwesasne) since 1975. Before that, the Ontario Ministry
of the Environment had been conducting annual vegetation assessment
programs and responding to complaints concerning the adverse
effects of airborne fluoride emissions on vegetation and cattle
since 1969. The source of the fluoride emissions was identified
as the Reynolds Metal Co. in Massena, New York. This
report presents the results of the most recent investigations
in 1989 and 1991 on Cornwall Island. |

Describes
a survey of vegetation in the vicinity of a brick plant in Snelgrove,
Ontario, to determine the extent of foliar
injury attributable to fluoride emissions from the plant and
to analyze concentrations of fluoride in maple tree foliage. |
