What are Common Challenges in Environmental Sampling?
Environmental sampling faces several challenges:
1. Sample Contamination: Ensuring samples are not contaminated during collection, handling, or analysis is critical. 2. Representative Sampling: Obtaining samples that accurately represent the environmental conditions can be difficult, especially in heterogeneous environments. 3. Temporal and Spatial Variability: Environmental conditions can vary over time and space, making it challenging to capture accurate data. 4. Detection Limits: Analytical methods must be sensitive enough to detect low concentrations of contaminants.
