Air Pollution and healthAt greater risk from air pollution:•Children (including teenagers)•People with asthma or another lung disease•Healthy adults who are active outdoors•People with cardiovascular disease (that’s your heart and blood vessels). Air pollution can contribute to heart attacks, strokes, cardiac arrest, congestive heart failure – and premature death. People in middle age and older are also at risk. In middle age, our risk for heart and lung diseases generally increases – and so does our risk from ozone and particle pollution

Fundamental Engineering

Fenomena Pencemaran Udara dan Kontrol:

The generation and control of air pollutants at their source. This first area

involves everything that occurs before the pollutant is released "up the

stack" or "out the tailpipe. “

The transport, dispersion, chemical transfonnation in, and removal of

species fromthe atmosphere. This second area thus includes all the

chemical and physical processes that take place between the point of

emission and ultimate removal from the atmosphere.

The effects of air pollutants on human beings, animals, materials,

vegetation, crops, and forest and aquatic ecosystems, including the

measurement of gaseous and particulate species.

data 1. Gas velocity

2. Gas temperature (dry and wet bulb)

3. Static pressure in the duct

4. Barometric pressure

5. Inside diameter or area of the duct

6. Concentration of desired pollutants, which may include size and size distribution of particulate

7. Emission source, name, and location

8. Date and time

9. Wind speed and direction

10. Control system operating conditions (pressure drop, temperature, liquid flow rate, and type)

11. Process operating conditions, including charge rate
