Questions and Answers

What are the two major groups of nutrients based on their composition?

Organic and inorganic nutrients.

What is the role of vitamin C in the human body?

Vitamin C helps form connective tissue.

Why is it not beneficial for humans to eat soil despite finding essential nutrients in it?

Eating soil would do little good because it is not a suitable source of nutrients for humans.

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.
