Flashcards in Common Atmospheric Pollutants and Their Sources Deck (26):
1

What's a major source of atmospheric pollutants

Combustion of fuels

2

What do most fuels including coal contain

Hydrocarbons and may contain some sulfur

3

What happens when incomplete combustion occurs instead of combustion

Some of the fuel doesn't burn as there's not enough oxygen
This produces carbon monoxide as well as carbon dioxide

4

What happens during combustion

The carbon and hydrogen are oxidised so carbon dioxide and water vapour are released into the atmosphere

5

When any alkane is completely combusted what's made

Large quantities of carbon dioxide

6

In what situation might incomplete combustion happen

If an engine is old/ poorly maintained

7

What is there more of if there's less oxygen in the reaction

Polluted gases

8

Whys carbon monoxide very dangerous

As it can stop your blood from carrying oxygen around the body by binding to the haemoglobin so less oxygen can

9

What 3 problems are caused by less oxygen in the blood

Fainting
A coma
Death

10

Why is carbon monoxide so hard to detect

As it has no colour or smell

11

What can happen if particulates in the air are inhaled

They can get stuck in your lungs and cause damage leading to respiratory problems

12

Give a way particulates in the air are bad for the environment

Cause global dimming as their cloud block light and reflect it back to space

13

What might carbon particles be

Carcinogenic

14

What do sulfur dioxide and oxides of nitrogen cause to our bodies and the environment

Respiratory problems
Acid rain

15

What does acid rain do

Kills plants and damages buildings

16

How is CO2 produced

When an alkane is completely combusted (fossil fuels)

17

How are CO and C (soot) produced

Incomplete combustion of fossil fuels

18

How are unburnt hydrocarbons produced

Escape out of cars exhaust

19

How are oxides of nitrogen produced

Combine at high temperatures with a spark

20

How is SO2 produced

From contaminating combusted fossil fuels

21

What health or environmental problems does CO2 cause

Global warming

22

What health or environmental problems does CO cause

Toxic

23

What health or environmental problems does C (soot) cause

Carcinogenic and harmful to lungs

24

What health or environmental problems does unburnt hydrocarbons cause

They can vaporise to cause photochemical smog

25

What health or environmental problems do NOx cause

Harmful to lungs
Cause acid rain

26

What health or environmental problems does SO2 cause

Harmful to lungs
Produced another type of acid rain
