Which of the following is not a part of risk assessment?

Correct option is B

Introduction

Environmental and health risk assessment is a systematic scientific process for estimating the likelihood and severity of harm from a hazard. It follows a defined sequence of technical steps, distinct from the subsequent management of that risk.

The correct answer is Risk Evaluation and Management. Risk assessment is the scientific, analytical process of characterising the nature and magnitude of risk, and it comprises four core steps: Hazard Identification, Dose-Response Assessment, Exposure Assessment, and Risk Characterisation.

Risk management — which includes risk evaluation, decision-making, selecting control options, and implementing regulatory or mitigation measures — is a separate stage that follows risk assessment.

It is not part of the assessment itself. Risk assessment answers "how harmful is this and to what extent?" using scientific data, whereas risk management answers "what should we do about it?" by weighing costs, benefits, feasibility, and policy considerations.

Because "Risk Evaluation and Management" belongs to the management phase rather than the assessment phase, it is the option that is NOT a part of risk assessment, making (b) the answer.

Additional knowledge
· Dose-Response Assessment — This IS part of risk assessment. It quantifies the relationship between the level of exposure (dose) to a hazard and the probability or severity of the resulting health effect (response), establishing thresholds or slope factors.
· Exposure Assessment — This IS part of risk assessment. It estimates the magnitude, frequency, duration, and routes of exposure of a population to a hazard, determining who is exposed and to how much.
· Hazard Identification — This IS part of risk assessment. It is the crucial first step, identifying whether a substance or agent is capable of causing harm (e.g., whether a chemical is carcinogenic, toxic, or otherwise hazardous).
