Both organic and inorganic contaminants

Acid Rain and its Effects On Our Aquatic Ecosystems In the past century‚ one of the greatest threats to North America ’s aquatic ecosystem has been the widespread acidification of hundreds of thousands of waterways. Acid rain has effected plant and animal life within aquatic ecosystems‚ as well as microbiologic activity by affecting the rates of decomposition and the accumulation of organic matter. What causes this poisonous rain‚ and what can be done to improve North America ’s water quality

Heavy metal contamination occurs though all facets of life such as air‚ water‚ food‚ soil‚ and in everyday objects and occurrences. When heavy metals enter the air from factories emissions and smoke‚ it is exposed to the body‚ which mostly affect your skin and lungs such as Cadmium and Arsenic. Common water contaminates are Chromium and Thallium‚ Chromium can enter the water source usually through spills and leaks from power plants. Thallium like other metals occurs naturally in water but some areas
