Conclusion

As this article illustrates, behind the seemingly simple question of "how much decontamination should be carried out after chemical contamination" lie multiple and complex lines of reasoning, which can be summarized as follows:

• for which chemical toxins is decontamination relevant and in which environments?

• what type of decontamination is required (operational vs. certified)?

• which populations are to be protected, and under what conditions are they exposed to residual contamination?

• what toxicological risks are considered acceptable?

• is it possible to measure analytically the thresholds considered acceptable?

• what is the capacity of reference laboratories in terms of sample...
