Sex effects of water pollution longer present much of a threat. This is also true for small amounts of chemicals present in the water.

This precipitation re-enters the ongoing circulation of water pollution. Another path in which the water can circulate is by flowing directly to the ocean. Pollutants are prevalent in coastal and open-ocean waters as contaminated water flows from point sources to the sea. These pollutants are then
