 Particulate Matter

Slide 1 - Tekstslide

What is the first thing that comes to mind when you think about particulate matter (fijnstof)?

Slide 2 - Open vraag

What is particulate matter?
- microscopic particles of solid or liquid matter suspended in the air
-  PM10 and PM2.5  
- absorbers and scatterers

Slide 3 - Tekstslide

Which group of particulates contribute to global warming?
A
absorbers
B
scatterers

Slide 4 - Quizvraag

How do particulates come to exist?
- 90 percent natural origins
- primary particles
- secondary particles
 

Slide 5 - Tekstslide

PM2.5
PM10
primary particles
secondary particles
combustion process
mechanical or chemical processes

Slide 6 - Sleepvraag

What are the health risks of particulate matter?
- long term: reduction of a human life, pulmonary diseases 
- short term: aggravation of lung diseases, irritation of the eyes, noses and throat, coughing, chest tightness and shortness of breath 
- fine particles can more easily enter the body, settle in lining of throat and nasal cavity, enter bloodstream

Slide 7 - Tekstslide

Which is more dangerous to humans? PM10 or PM2.5?
A
PM10
B
PM2.5
C
both are equally dangerous

Slide 8 - Quizvraag

What is the impact of particulate matter on the environment?
- direct effects
- classification about  scatterers and absorbers
- indirect effects; cloud forming, haze
- chemical composition

Slide 9 - Tekstslide

What is an indirect effect of particulate matter on the environment?

Slide 10 - Open vraag

Sensor
- SODAQ
- measures several data; PM, GPS, quality of road surface, temperature, humidity, air pressure, time, organic gasses, voltages over the battery
- measured every 10 seconds

Slide 11 - Tekstslide

PM levels in the Netherlands
- gradually dropping
- below required norm
- doesn't reach WHO goal

Slide 12 - Tekstslide

PM levels rest of the world
- WHO air quality guidelines
- lowest in Europe is Sweden
- a big problem in China
- a lot of natural sources in Nigeria
