LaoExcess nitrogen from agriculture can lead to eutrophication in bodies of water. This excess nitrogen causes an overgrowth of algae, which reduces oxygen levels in the water when it dies and decomposes. This low oxygen level can suffocate fish and other aquatic organisms, leading to fish kills.

Does chlorine kill fish?
Yes, chlorine is harmful to fish and can kill them if they are exposed to high levels of it in their water. It is important to always use a dechlorinator when setting up a new aquarium or performing water changes to make the water safe for fish.
When excess fertilizer drains into a lake what may occur harming fish populations?
eutrophicationeutrophicationFertilizer in a lake helps algae grow. Up to a certain point, that is good. The algae turns carbon dioxide into oxygen and adds oxygen to the water. However, after that point, the algae covers the lake. Oxygen from the air can not get to deeper water. Dead algae falls to the bottom of the lake and decomposes. The process of decomposing uses up oxygen. The amount of oxygen in the lake drops below the point where fish can survive. Thus, over fertilization leads to a fish kill.
Can nitrogen kill us?
Nitrogen is not inherently toxic to humans, but inhaling pure nitrogen in an environment with limited oxygen can displace the oxygen we need to breathe, leading to suffocation. This is known as nitrogen asphyxiation and can be deadly.
Is liquid nitrogen poisonous?
Liquid nitrogen is not poisonous, however, it can be dangerous if it comes into contact with skin or if it is inhaled because of its extremely low temperatures. It can cause severe burns or frostbite upon contact with skin and can displace oxygen in the air if inhaled in high concentrations.
Liquid Nitrogen kill warts?
Yes, liquid nitrogen can be used to freeze and remove warts. This process is called cryotherapy. The extreme cold temperature of the liquid nitrogen destroys the wart tissue, causing it to die and eventually fall off. It is a common and effective treatment for warts.
