First: Air quality
Air quality is measured to control pollutants that directly affect public health and the environment, in accordance with the standards and requirements of the National Center for Environmental Compliance. NCEC The most notable indicators include:
- Sulfur dioxide (SO₂)
- Carbon monoxide (CO)
- Nitrogen oxides (NOx)
- Ground-level ozone (O₃)
- Fine particulate matter (PM10 – PM2.5)
- Hydrogen sulfide H2S
- Ammonia NH3
- Volatile organic compounds VOCs
- Emissions of gases and particulate matter from stationary sources (chimneys)
- Air Quality Index (AQI)
Second: Water quality
Water analyses are conducted to ensure its safety for human and environmental use, in accordance with the standards and requirements of the National Center for Environmental Compliance. NCEC Includes:
1. Physical criteria (Physical Parameters)
- Temperature (Temperature)
- Turbidity/cloudiness (Turbidity)
- Color, taste, and smell
- Total dissolved solids (Total Dissolved Solids – TDS
2. Chemical standards (Chemical Parameters)
- Hydrogen index (pH)
- Dissolved oxygen (Dissolved Oxygen – DO)
- Biochemical oxygen demand (Biochemical Oxygen Demand – BOD)
- Total hardship (Total Hardness)
- Nutrients (Nutrients)
- Heavy metals: such as lead (Lead), arsenic (Arsenic), cadmium (Cadmium).
- Residual free chlorine
3. Biological and microbiological criteria ((Biological/Microbiological)
- Total coliform bacteria and fecal coliform bacteria (Total and Fecal Coliform
- Other pathogenic microorganisms such as parasites and viruses
- Water Quality Index (Water Quality Index – WQI)
Third: Soil
Soil analysis contributes to assessing the extent of soil contamination and its suitability for agriculture or urban development, and is carried out TheMeasurement according to the standards and requirements of the National Center for Environmental Compliance Monitoring NCEC Includes:
- Organic and petroleum pollutants
- Heavy metal content

Fifth: Radiation
Measurements are taken at sensitive locations to ensure safety from radiation exposure, including:
- Measuring radioactivity:
- Alpha rays
- Beta rays
- Gamma rays
Sixth: Work Environment
Work environment factors are assessed to ensure occupational safety and improve employee comfort, and measurements include:
- Light intensity
- Ventilation
- Temperature
- Humidity level
