Summary
Despite early reports of respiratory illness in asbestos factory workers, Canadian authorities denied health impacts for decades. Official inquiries confirmed asbestos-related diseases, yet industry public relations efforts continue to downplay risks and oppose bans.
Area of Science:
- Occupational Health
- Environmental Science
- Public Health Policy
Background:
- Commercial asbestos exploitation began in the late 1870s, with Canada as a primary global source.
- Early reports of severe respiratory disease among asbestos factory workers emerged in Europe starting in 1898.
Observation:
- Canadian authorities repeatedly denied adverse health effects on asbestos workers for over 40 years.
- A 1955 report documented asbestosis in 128 out of 4,000 asbestos workers, with diagnoses confirmed radiographically and at autopsy.
Findings:
- Inquiries in 1976 and 1984 confirmed asbestos-related diseases but did not impact asbestos exports.
- Industry public relations campaigns successfully minimized the perceived risks of asbestos exposure.
Implications:
- Despite international consensus and national bans on asbestos use, Canadian industry continues to influence scientific and medical opinions.
- The long-term health consequences of asbestos exposure remain a critical public health concern, necessitating continued vigilance and regulatory action.

01:13Mortar Joint Deterioration in Masonry
Mortar joint deterioration is a significant concern in masonry structures, with water accumulation in the joints leading to damage from freeze-thaw cycles. The repeated expansion of water during freezing and its melting during thawing develop and propagate cracks in the masonry joints. Eventually, this leads to the spalling of mortar from the joints, loosening masonry units and weakening the structure. The deteriorated mortar joints are also vulnerable to moisture intrusion into the walls.

01:29Sulfate Attack on Concrete
Sulfate attack on concrete is a deterioration process characterized by a whitish discoloration beginning at the edges and corners, accompanied by cracking and spalling. This phenomenon occurs when sulfates react with the components of hardened concrete, forming compounds like calcium sulfate and calcium sulfoaluminate which occupy more space than the substances they replace, causing the concrete to expand and disrupt.

Intentional torts in healthcare refer to deliberate actions that cause harm or infringe on the rights of others. Understanding these torts is crucial for healthcare professionals to avoid legal liabilities and maintain ethical standards in patient care.
01:31Defense Against Bacterial Pathogens
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

01:02Role of Microtubules in Cell Wall Deposition
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of disassembly and...
01:22Thermal Insulation in Masonry Walls
In hot, dry climates, the thermal mass of masonry walls can be beneficial, absorbing heat during the day and releasing it at night, thereby stabilizing indoor temperatures. However, in most other climates, additional insulation is necessary to enhance thermal resistance.
External insulation can be applied using an Exterior Insulation and Finish System (EIFS), which involves affixing panels of plastic foam to the wall and covering them with a polymeric stucco reinforced with glass fiber mesh.
