4.2 Parameters Monitored

Air Quality: Monitoring parameters such as particulate matter, sulfur dioxide, nitrogen oxides, and volatile organic compounds. In mining operations, dust emissions are a major concern, and in the oil and gas industry, emissions from combustion processes are monitored.
Water Quality: Measuring parameters like pH, dissolved oxygen, heavy metals, and hydrocarbons. In mining, water runoff from waste dumps can contaminate nearby water bodies, and in the oil and gas industry, produced water disposal needs to be monitored to ensure water quality protection.
Soil Quality: Assessing factors such as soil fertility, soil structure, and the presence of contaminants. In mining, soil disturbance due to overburden removal can affect soil quality, and in the oil and gas industry, soil contamination from spills may occur.
Biodiversity and Wildlife Habitats: Monitoring the presence and abundance of different species, as well as changes in their habitats. In extraction plants located in forested areas or near wetlands, there is a need to protect wildlife habitats and maintain biodiversity.

4.3 Monitoring Technologies

Remote Sensing: Using satellite imagery or aerial drones to monitor large - scale environmental changes. For example, satellite images can be used to monitor deforestation around mining sites or changes in land cover due to oil and gas exploration.
In - situ Sensors: These are placed directly in the environment to measure parameters in real - time. For example, in - situ water quality sensors can continuously monitor the quality of water bodies affected by extraction plants.
Laboratory Analysis: Samples of air, water, and soil are collected and analyzed in a laboratory for a more detailed assessment of environmental parameters.
