The selection of environmental factors affecting evidence quality as a common challenge during the collection of evidence is particularly significant due to the inherent unpredictability of outdoor or even indoor environments. Factors such as weather conditions, temperature changes, humidity, and other atmospheric conditions can significantly alter the state of physical evidence. For instance, rain can wash away or dilute biological samples, while extreme temperatures can degrade certain types of evidence, such as trace materials.

Additionally, environmental factors also include conditions like lighting, which can affect visibility and the ability to accurately observe and document evidence. This makes the role of the Crime Scene Investigator crucial in both recognizing these challenges and adapting their methods accordingly to ensure the integrity and quality of the evidence collected. Understanding these environmental influences is vital for maintaining the chain of custody and supporting the overall forensic process.
