Is there any effect on living things if miso soup is poured directly into the river?

Miso soup does not contain harmful substances to living things, but it contains a large amount of organic matter, and the BOD is said to be about 35,000 mg / liter. Regarding the effect of flowing into the river where the fish is in question, some of the organic matter in the miso soup becomes food for fish or decomposed by the river's self-cleaning action.

However, the self-cleaning action in the river is limited, and if pollutants such as organic matter flow into the river more than the purification capacity, the pollutants cannot be decomposed and become a dirty river where fish etc. can not live . Regarding miso soup, even if the amount of water per person flows is small, the river will be dirty if everyone who comes to Barbequeeze flows into the river or drains waste liquid that has washed dishes using detergents.

It is natural to take home your garbage home, but there is no problem with the rest of the miso soup, etc., if you drain it into the sewer pipe connected to the water reclamation center.

Similar to other foods, it is important to eat everything you make and not to make it more than necessary.
