Document Summary
Environmental problems: as we have talked about, degradation of the planet"s environment has accompanied human population growth throughout history. Nitrate (no3-) has been of particular concern. Essential nutrient for plant growth, soluble in water and passes through the soil. Significant groundwater contaminant, can persist for decades. Most serious in areas with shallow water tables, high agricultural activity, well-drained soils, and. Low oxygen levels in infants reduced woodlands: however, in terms of natural resources, runoff into streams and rivers has been a much bigger problem. Oligotrophic low nutrient levels, low primary, secondary productivity. Hypereutrophic over-productive, system cannot assimilate nutrient load through normal pathways: time out for science. We want to determine whether a secchi disk is adequate for measuring turbidity in louisiana and canada lakes. Loss of dissolved oxygen: diurnal oxygen production high, nocturnal respiration high, algae can become self-limiting, mortality and decomposition. Fertilizer use in the upper mississippi river drainage.
