Inorganic Pollutants

Haven't you always wanted to know the difference between these three inorganic pollutants? I know I have!

Finally the information is here, tell all your friends!

Aluminum is the most abundant of the three metallic elements which constitutes for about 8.1% of the Earth's crust, while Tin is at 0.00099% and Lead only 0.00022%.

Acceptable limits in Canadian drinking water:

  • Tin - 1 - 2 ppm
  • Aluminum - 0.05 - 0.2 ppm
  • Lead - 0.010 ppm

HOW are we exposed to these pollutants??


  • can be found in the air, soil, water, food, and consumer products.
  • many lead based items in homes like piping, paints, toys and blinds.
  • leaching and pollution to environment (air,soil, water) from industrial activity


  • found in air, water, and soils near areas where tins are mined, manufactured or used
  • absorbed through food, breathing and through the skin
  • burning of fossil fuels
  • toothpaste, soaps, food additives as well as dyes may contain tin
  • triphenyltin, used in pesticides can leach into soil and groundwater


  • found in air, food, water (absorbed through skin, lungs, intestinal tract)
  • mining ore, recycling scrap aluminum, emissions from Bayer Process and Hall-Heroult Process
  • ingesting food, drugs, drinking water can expose to aluminum



What can YOU do!?

  • Remove LEAD based items from your home like piping, paints, toys and blinds
  • Mitigate LEAD contamination in soil and water

  • Use less TIN foil
  • Avoid use of agricultural pesticides, and plastic industries for less TIN exposure

  • Reduce use of ALUMINUM cans and replace with stainless steel
  • Avoid ALUMINUM cook wear and replace with cast iron, glass, or wax paper
