Which of the following would most likely be considered point source pollution?

Chemical dumping into a river by a factory

Increased phosphates from household detergents

Fertilizers being carried away from a farm by runoff

Sediment from improperly managed construction sites

Answer 1

You posted this in the match section...it's a biology question.

1. The chemicals come from the factory, a point source.
2. The phosphates could come from a variety of sources.
3. The fertilizers come from a farm, a point source.
4. The sediment comes from construction sites, each a point source.

Answer 2

I meant math, not match!

Answer 3

where is that section?

Answer 4

I have no idea what textbook you're using. You asked a biology question, I answered it. You don't need a textbook for this question anyway...a point source is exactly what it sounds like. A source is where something comes from, a point is a single place.
