Study Notes
Phosphorus: Environmental Impact
- Excessive phosphorus in water bodies leads to uncontrolled algae growth, impacting aquatic ecosystems.
- Algae blooms can deplete dissolved oxygen levels, endangering fish and aquatic animals.
- Some algae produce toxins, posing health risks to wildlife and humans.
- Manufacturers have reduced phosphorus content in detergents due to environmental concerns.
Phosphorus Regulation in Alberta
- Alberta's Environmental Protection and Enhancement Act regulates phosphorus discharge from municipalities and industries.
- Pollution prevention strategies and advanced technologies have enabled reductions in phosphorus in wastewater.
- Some municipalities have adopted phosphorus reduction programs, successfully lowering discharge into water bodies.
- Managing phosphorus runoff from agricultural and urban areas is essential; fertilizer use requires careful oversight.
Tips to Reduce Phosphorus Pollution at Home
- Use fertilizers appropriately and test soils before application to avoid over-fertilization.
- Properly dispose of pet waste to minimize nutrient runoff.
- Protect riverbanks by maintaining vegetation to reduce soil erosion.
- Compost phosphorus-rich kitchen scraps instead of using garbage disposals to prevent wastewater contamination.
Body Chemistry and Nutrients
- The human body consists of chemicals derived from food, categorized as organic and inorganic nutrients.
- Organic Compounds: Include carbohydrates, proteins, lipids, and vitamins; essential for health and mostly derived from plants.
- Vitamin C is critical for connective tissue formation; deficiency can lead to scurvy, characterized by bleeding gums and bruising.
- Inorganic Compounds: Minerals necessary for bodily functions; not destroyed by cooking.
- Microminerals are essential in minute quantities, essential for enzyme functions and overall health.
Health Implications of Nutrient Deficiencies
- Iodine deficiency can cause goiter, swelling of the thyroid, prevalent in regions with low seafood consumption.
- Nutritional deficiencies can yield severe health consequences, impacting growth, energy, and repair of body tissues.
- Soil contains essential nutrients but is not a viable food source for humans; direct consumption would be ineffective.
