Environmental Measurements Flashcards
Is any data collection, activity, or investigation involving the assessment of chemical, physical, or biological factors in the environment which affect human health or the quality of life.
Environmental MEASUREMENT
Refers to tools and techniques designed to observe an environment, characterized its quality, and established environmental parameters, for the purpose of accurately quantifying the impact an activity has on an environment.
Environmental MONITORING
The air pollutant indicator assesses pressures from specific pollutants on atmospheric air across individual countries, but also identifies pressures from particular national sectors like energy, transport, industrial processes, agriculture, and waste management.
AIR monitoring
Air/atmospheric levels can be monitored using a variety of sensors
Lahat may sensor sa dulo:
- Temperature
- Humidity
- Carbon dioxide
- Oxygen
Monitoring not only helps manage soil moisture and plants health, but the soil is also related to many natural processes and helps us understand water resources both locally and regionally.
SOIL monitoring
Measuring the ph: as many factors such as pollution, climate, and the environment can affect the ph in soil, measuring the ph of soil also helps us understand soil environment.
SOIL monitoring
Can be defined as repeated with (a defined frequency) analysis of water quality in permanent points data processing and prognosis of trends to support actions focus on interception and remediation of adverse anthropogenic impact on the aquatic environment.
WATER monitoring
Looks at production and consumption. for waste management contributes to climate change and air pollution directly impacting the environment and exposing humans to harmful substances, putting pressure on human health systems
WASTE monitoring
Waste monitoring five stages, least to most harmful
- Prevention
- Reuse
- Recycle
- Recovery
- Disposal
Refers to any gas that has the property of absorbing infrared radiation (net heat energy) emitted from earth’s surface and the radiating it back to earth’s surface thus contributing to the greenhouse effect.
Greenhouse GAS
Have a profound effect on the energy budget of the earth system despite making up only a fraction of all atmospheric gases.
Greenhouse GASES
Major greenhouse gases
- Water vapor
- Carbon dioxide
- Methane
- Nitrous oxide
Is the most potent greenhouse gas in earth’s atmosphere, but its behavior is fundamentally different from that of the other greenhouse gases.
Water vapor
Is not as a direct agent of radiative forcing but rather as a climate feedback - that is as a response within the climate system that influences the systems continued activity.
Water vapor
Is the most significant greenhouse gas. Natural sources of atmospheric co2 include outgassing from volcanoes, the combustion and natural decay of organic matter, and respiration from aerobic organisms.
Carbon dioxide (CO2)
This sources are balance on average by a set of physical chemical or biological processes called - - - that tend to remove CO2 from the atmosphere
Sinks
Is the second most important greenhouse gas. It is more potent than co2 because the radiative forcing produced per molecule is greater.
Methane (CH4)
Is an odorless, colorless, flammable gas. It is used primarily as fuel to make heat and light it is also used to manufacture organic chemicals it can be formed by the decay of natural materials and is common in landfills, marshes, septic systems, and sewers.
Methane
Is emitted during agricultural land use and industrial activities combustion of fossil fuels and solid waste as well as during treatment of wastewater.
Nitrous oxide (N2O)
The gas is also used as a propellant in food aerosols. In automobile racing it is injected into an engine air intake the extra oxygen allows the engine to burn more fuel per stroke.
Nitrous oxide
It is a pain relief method or laughing gas as something used to help relax the patient.
