How do you do air monitoring?
Ways to sample ambient air
- Passive Monitoring. Diffusion tubes absorb a specific pollutant from the ambient air – no power supply is needed.
- Active (Semi Automatic) Sampling.
- Automatic point monitoring.
- Photochemical and optical sensor systems.
- Remote optical/long-path monitoring.
What has Singapore done to protect the environment?
Singapore has taken early measures on sustainable development, such as managing the growth of our vehicle population and making the switch from fuel oil to natural gas, the cleanest form of fossil fuel, to generate electricity.
