Urban Farm DB summary

This official U.S. EPA page on 'The Effects' of nutrient pollution explains that excess nitrogen and phosphorus entering air and water cause algal blooms, degrading water quality and reducing dissolved oxygen. It states cyanobacteria can release toxins that sicken people and animals via contact, drinking water, or contaminated seafood, that nitrates in drinking water pose risks to infants, and that excess airborne nitrogen contributes to ammonia and ozone formation. The page itself contains no specific numeric statistics on economic damages or dead-zone area.
