Proposal on limits for chemical exposure in saturation divers' working atmosphere: the case of benzene.

abstract：:Perhaps no other topic in risk analysis is more difficult, more controversial, or more important to risk management policy analysts and decision-makers than how to draw valid, correctly qualified causal conclusions from observational data. Statistical methods can readily quantify associations between observed variable...
