Environmental monitoring indices are numerical values used to represent the state of the environment (environmental indices). They are used to address environmental issues by measuring and evaluating environmental changes. Environmental monitoring indices can include parameters such as the accumulation of harmful factors, pollution levels, changes in flora and fauna, and ambient temperature.

Workplace environmental indices can have serious impacts on employees’ health. For example, high or low temperatures can lead to conditions such as fatigue, headaches, weight gain, or decreased immunity. Natural light or sun exposure may result in sunburn, skin aging, or increased risk of skin cancer. Exposure to noise, air pollution, or toxic substances can also cause severe health issues for employees.
