Phase 3: Laboratory Analysis

This third phase is conducted by an independent internationally-accredited laboratory, to ensure unbiased scientific analysis.

Samples recovered by the UNEP teams will be individually labeled with a unique reference number that includes the exact geographic coordinates of the location from where each was taken. This number will stay with the samples throughout the laboratory analysis phase, allowing for cross-referencing.

UNEP experts will ship the samples to the laboratory on a regular basis. Sample integrity will be maintained by using containers provided by the laboratory and standard refrigeration processes throughout their transportation.

Each sample will be analysed for a range of contaminants, such as hydrocarbons, phenols and heavy metals.

The analysis of air samples will focus on pollutants associated with gas flaring, as well as those related to oil spills.
