Answer 4

Single incident causing pollution (Chernobyl)

Question 5

Chronic pollution

Answer 5

Long term pollution

Question 6

What is chronic pollution often associated with?

Answer 6

Non point source pollution

Question 7

What is acute pollution often associated with?

Answer 7

Point source pollution

Question 8

Biodegradable pollution

Answer 8

Can easily be broken down and will eventually be harmless

Question 9

Persistent pollution

Answer 9

Non biodegradable pollution

Question 10

Primary pollutant

Answer 10

Air pollutant emitted directly from a source

Question 11

Answer 11

Not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere

Answer 17

Can control the spread of typhus from lice and malaria from mosquitos; inexpensive to produce; saves millions of lives
