Introduction
Importance of stable environment for long-term preservation
Unstable storage environment accelerates deterioration
-Warmer temperatures speed up deterioration processes
―An increase of 10°C doubles chemical reactions
―Extraction of lipids and proteins goes faster
-Cooler temperatures condense lipids and promote paraformaldehyde formation
-Fluctuations -Stress specimens -Stress containers and container seals -Relative humidity is temperature dependent -Short-term exposure to relative humidity >65% can trigger mold outbreak
