Health Hazards: Environmental, Chemical, and Biological Risks
Health Hazards: An Overview
Physical Environmental Insults: Ionizing radiation is a form of energy that can modify the structure of matter and cause changes in our cells.

Vertical Temperature Gradients
Vertical Gradients: The difference in temperature between two points located at an altitude difference of 100 meters.
The Vertical Temperature Gradient (GTV) represents the vertical variation in air temperature under static or resting conditions. Its value varies with height, latitude, and season.
Inversion: An airspace where the temperature increases with altitude instead of decreasing, i.e., when the GTV is negative. Example: Winter.
Dry Adiabatic Lapse Rate (GAS): This
