Miscou Harbour Eelgrass Classification

True colour aerial photography at 57 centimetre resolution was collected on August 20th and 24th, 2009 by Nortek Resources of Thorburn, Nova Scotia (http://www.nortekresources.com/). Image classification was conducted using eCognition Developer v. 8 Software, which first segments the image into spectrally similar units, which were then classified manually. Additionally, the Department of Fisheries and Oceans (Gulf Region, Moncton, NB) conducted a visual field survey in the same field season at 103 sites. From these sites 70% were used to assist in image classification, while the remainder were used to assess accuracy. Three classes were identified:  
  
                 i. Good Quality Eelgrass: relatively dense, clean, green blades with minimal epiphytes or algal growth.   
  
                 ii. Medium Quality Eelgrass: predominately green blades that may have some epiphyte or algal growth. These stands can be less or equally dense as Good Quality Eelgrass, but the best grasses are certainly not as abundant.  
  
                 iii. Eelgrass Absent/Poor Quality: eelgrass is absent, or if it is present it is typically covered with epiphytes or other algae or dying or dead.   
  
                 Eelgrass was classified correctly 96.7% of the time (30/31 = 0.967).

A Deep Dive into the Complex Chemical Mixture and Toxicity of Tire Wear Particle Leachate in Fathead Minnow

Tire wear particles end up on roads where they may run off into nearby rivers and lakes by rain and snowmelt. This study examined how toxic these tire particles are to eggs and the newly hatched larvae of the fathead minnow (Pimephales promelas). Tire particles were finely ground up and were immersed in water for 1, 3, and 10 days. Fathead minnows were then exposed to both filtered (tire particles removed) and unfiltered (tire particles left in) water to test whether the number of days of leaching, as well as the presence, or non-presence, of tire particles in the water had any effect in toxicity to the fathead minnows.


We observed more toxic effects (deformities, diminished pigmentation, etc.) in hatched minnows that were exposed to a longer leaching time (10-day), as well as to the unfiltered leachates. Our study provides insight into the types of chemicals likely significant in tire leachates and improves our understanding of the ecotoxicological impacts of tire wear particles.

Charter Statement - Bill C-72: An Act respecting the interoperability of health information in Canada and the prohibition of data blocking by health information technology vendors

Section 4.2 of the Department of Justice Act requires the Minister of Justice to prepare a Charter Statement for every government bill to help inform public and Parliamentary debate on government bills. One of the Minister of Justice’s most important responsibilities is to examine legislation for inconsistency with the Canadian Charter of Rights and Freedoms [“the Charter”]. By tabling a Charter Statement, the Minister is sharing some of the key considerations that informed the review of a bill for inconsistency with the Charter. A Statement identifies Charter rights and freedoms that may potentially be engaged by a bill and provides a brief explanation of the nature of any engagement, in light of the measures being proposed.

A Charter Statement also identifies potential justifications for any limits a bill may impose on Charter rights and freedoms. Section 1 of the Charter provides that rights and freedoms may be subject to reasonable limits if those limits are prescribed by law and demonstrably justified in a free and democratic society. This means that Parliament may enact laws that limit Charter rights and freedoms. The Charter will be violated only where a limit is not demonstrably justifiable in a free and democratic society.

A Charter Statement is intended to provide legal information to the public and Parliament on a bill’s potential effects on rights and freedoms that are neither trivial nor too speculative. It is not intended to be a comprehensive overview of all conceivable Charter considerations. Additional considerations relevant to the constitutionality of a bill may also arise in the course of Parliamentary study and amendment of a bill. A Statement is not a legal opinion on the constitutionality of a bill.

Guidelines for Canadian recreational water quality: Microbiological pathogens and biological hazards: Pathogenic microorganisms

Numerous pathogenic microorganisms can potentially be found in recreational environments. The three main types are bacteria, viruses and protozoa. Many occur as a result of contamination from human or animal wastes, whereas some are free-living microorganisms that exist naturally in the recreational water environment. A fourth type that may be of concern at some beaches, particularly associated with beach sand, are fungi.

Southern Ontario Surficial 3D Model

To support improved groundwater geoscience knowledge for southern Ontario, a regional 3-D model of the surficial geology of southern Ontario has been developed as a part of a collaboration between the Ontario Geological Survey and the Geological Survey of Canada.  Covering approximately 66,870 km2 in area, the model is a synthesis of existing geological models, surficial geology mapping, and subsurface data.  The model is a simplified 9-layer reclassification of numerous mapped local surficial sediment formations in places over 200 m thick with a total volume of approximately 2,455 km3.  The model integrates 1:50,000 scale surficial geology mapping with 90 m bathymetrically corrected topographic digital elevation model (DEM) and 8 existing local 3-D models.  Archival subsurface data include 10,237 geotechnical and stratigraphic boreholes, 3,312 picks from geophysical surveys, 15,902 field mapping sites and sections, 537 monitoring and water supply wells and 282,995 water well records. Roughly corresponding to regional aquifer and aquitard layers, primary model layers are (from oldest to youngest): Bedrock, Basal Aquifer, Lower Sediment, Regional Till, Post Regional Till Channel Fill, Glaciofluvial Sediment, Post Regional Till Mud, Glaciolacustrine Sand and Recent Sediment / Organics.  Modelling was completed using an implicit modelling application (LeapFrog®) complemented by an expert knowledge approach to data classification and rules-based Expert System procedure for data interpretation and validation. An iterative cycle of automated data coding, intermediate model construction and manual data corrections, expert evaluations, and revisions lead to the final 3-D model. A semi-quantitative confidence assessment has been made for each model layer surface based on data quality, distribution and density.  This surficial geology model completes the development of a series of regional 3-D geological and hydrogeological models for southern Ontario.

Guidelines for Canadian drinking water quality boron: Rationale for maximum acceptable concentration

Boron can be present in drinking water supplies through weathering of boron-containing rocks and soils, seawater spray and volcanoes as well as from anthropogenic sources such as wastewater from municipal sewage treatment and industrial processes, pesticide application and other human activities. In most Canadian drinking water supplies, boron is below 0.1 mg/L. Higher concentrations of boron (1 mg/L to 8 mg/L) can be found in certain areas of Canada, particularly in groundwater supplies in areas with naturally occurring boron. The main source for Canadians' exposure to boron is through food, although consumer products can also contribute significantly to exposure. Exposure through drinking water can contribute up to 16% of total dietary exposure.

Reproduction and development are considered to be the most sensitive health endpoints for boron toxicity. Studies in humans have found possible associations between boron and effects to reproduction and development. However, these have several design limitations and cannot be used for risk assessment. Studies in animals have consistently observed adverse effects to the male reproductive system following ingestion of high levels of boron, which supports effects seen in human studies. Testicular effects observed in dogs were the most sensitive endpoint and are used to establish the HBV of 0.1 mg/L.

The guideline development process considers the ability to measure a contaminant in drinking water. There are several analytical methods available for the analysis of total boron in drinking water at concentrations below the HBV.

The guideline development process also considers whether the maximum acceptable concentration (MAC) is practically achievable using current drinking water treatment technologies. For municipal-scale treatment plants, the 2 most effective and commonly used treatment technologies for boron removal are RO and IX using a boron selective resin. Data from treatment plants indicate that a treated water concentration at the HBV of 0.1 mg/L is not achievable for most systems. While IX with a boron selective resin may be theoretically capable of removing boron from drinking water to below 0.1 mg/L, the operating conditions that would be required would be extremely challenging and are not considered to be practical. In general, when source concentrations are 8 mg/L or less, treated water concentrations of less than 5 mg/L are achievable using RO and IX (with BSR) that have design and operating conditions for boron removal.
