6.03 APES Acid Deposition Brianna RamsonJane SelwaINTRODUCTIONAcid Deposition is one of the many consequences of over reliance on fossil fuels. Acid deposition can be either wet, I.e rain, fog or snow or dry, i.e particulate matter. Indicators of acid rain deposition include a drop in the pH of bodies of water. The two chemical precursors, sulfur dioxide and nitrogen oxides react with water, sunlight, oxygen and carbon dioxide to form acid deposition. Shallow soil, certain types of rock like granite, and vegetation destroyed by fire or insect infestations are more prone to the effects of acid deposition. The primary sources of hydrogen and sulfur oxides come from electric utilities that burn coal, transportation, and industrial plants. Acid deposition can be acute and episodic or chronic. The acute form occurs after heavy snow fall or floods. Chronic acid deposition occurs in bodies of water, like the one studied in this lab. The consequences of acid deposition include leaching, nitrogen over saturation that harms plant/tree life, algae blooms from eutrophication and loss of coastal biodiversity.In this lab, the acidity of Angeline stream in Westport,
