What needs to be clarified
The review could assess the period and area represented by the results and identify data needed to examine a possible source. The question should be defined before selecting an observation and testing programme.
Materials to prepare
- The complete report with times, locations, indicators, methods and measurement conditions.
- A dated, location-specific chronology of odour observations and circumstances.
- Available weather information, operation records of possible sources and previous studies.
What to compare
- Whether the measurement period and conditions match the reported circumstances.
- Whether locations and weather records allow alternative sources to be compared.
- Whether the measured indicators address the actual question rather than only describe general air conditions.
Possible outcome of the analysis
A possible output is a comparison map of observations and measurements, testable hypotheses and a reasoned list of additional data. Findings supported by the report can be separated from circumstances outside its scope.
Limits of the conclusions
An odour alone does not establish an exceeded limit, a particular source or harm to health. Daytime readings cannot establish absence of night-time effects without justification; medical conclusions require separate expertise.
