Causes

Effects

Sediments and excessive nutrients , especially phosphoruscausealgal growth , low dissolved oxygen levels , fish kills and odors

The nutrientscausethe growth of algae , robbing the water of oxygen needed for fish to survive

This nutrient pollutioncausesincreased plant and algae growth which reduces the amount of dissolved oxygen in water

Fertilizer that enters our lakes and streamscan causealgae to grow and use up oxygen that fish need to survive

Excess levels of nitrogen in watercan causealgal blooms , loss of oxygen , fish kills

in too high of amounts in watercan causealgae to grow and harm fish by reducing oxygen levels

Phosphorus ... a nutrientcausesexcessive aquatic plant growth , which reduces the amount of oxygen in the water available for fish

The fertilizer residuewill causealgae to grow , which uses up oxygen that fish need to survive

High phosphorus levelscauseexcessive plant growth that depletes oxygen in the lake , killing fish

eventscan leadto excessive algal growth , reduced dissolved oxygen , and fish kills

High phosphorusleadsto plankton growth ( algae ) and reduced oxygen in water ( fish kills

The phosphoruscontributesto algal growth , which can severely deplete dissolved oxygen levels in the water

In addition , most detergents contain phosphates , which build up in streams and lakes and upset the natural balance in waterwayscausingblooms of algae which deplete the dissolved oxygen fish need to live

Change water conditionscausingheavier aquatic plant growth , oxygen loss , and fish kills

a pondcausingexcess algal growth that depletes oxygen , suffocating fish

Phosphates and nitrates from these sources enter lakes and riverscausingexcessive algal growth , which deprives fish of oxygen

riversleadsto excessive plant growth and less oxygen for the fish

nutrients ... the watercan resultin algae blooms and decreased oxygen for fish

nutrient - rich soil ... riversleadsto excessive plant growth and less oxygen for the fish

wastesleadsto stagnation and loss of the dissolved oxygen needed by fish

phosphorus ... the watercan resultin algae blooms and decreased oxygen for fish

accumulation of wastesleadsto stagnation and loss of the dissolved oxygen needed by fish

Decomposition of decaying algae in late summercommonly causesa fish kill due to rapid dissolved oxygen depletion

in turncausesincreases in aquatic plant growth ... and ultimately s drop in dissolved oxygen

leaves ... the watercan resultin algae blooms and decreased oxygen for fish

a key nutrientcausesalgae growth and subsequent oxygen loss

This could be bad for a creekwould causeto grow and associated oxygen depletion impacting fish

too many nitrates and phosphateshave causedalgae growth that depletes water - oxygen levels for aquatic organisms

nutrientscausean outburst in algae growth that depletes dissolved oxygen in aquatic systems

inputs of nutrients ( phosphorus , P , and nitrogen , N ) to freshcan causeexcessive aquatic plant growth , depletion of oxygen

Phosphates in soapscausealgae growth that can pull oxygen out of the water and cause fish kills

an oxygen consumption additioncausedan increase in dissolved oxygen in the water

2012 Global Warmingmay Leadto Depletion in Fish Growth

Excess nutrients such as phosphoruscan causealgal growth that depletes oxygen
