Pollution and Bio indicators

What are examples of pollution? Air pollution Waste products Climate change- acid rain, acid snow Waterway contamination Human health – smog/ allergies Land and ground water contamination Noise pollution Odor

Point Source Pollution A form pf pollution that you can point to and say “that is where the pollution is coming from.

Non-Point Source Pollution This is when there is pollution in a water source that you can not find a specific point where it is being polluted. Maybe there are several areas that are all contributing to the pollution.

Run-off Percolate

What are bio Indicators? Things within the environment that tell us the health of the ecosystem.

Bio Indicators Dissolved Oxygen levels Smell Nitrogen levels Color Life- Number of Species Hardness Light – Turbidity pH Secchi disc Salinity Suspended Sediment
