What is the correct order of risk assessment due to exposure of some chemicals to humans? Choose the correct answer from the options given below:

The correct order of risk assessment is hazard identification, then dose response assessment, then exposure assessment, then risk characterization.

Hazard identification comes first to establish whether a chemical can cause harm at all.

Dose response assessment follows, relating the level of exposure to the severity of the effect.

Exposure assessment then estimates how much of the chemical people actually come into contact with.

Risk characterization is the final step, combining the earlier findings into an overall estimate of risk.

This four stage framework underlies environmental and public health risk analysis.
