Environmental Health Inspection and Assessment Flashcards

What is the primary purpose of an environmental health inspection?

Answer: To evaluate compliance with environmental health regulations, identify hazards, and protect public health

Environmental health inspections are conducted to assess compliance with applicable regulations, identify conditions that pose risks to public health, and initiate corrective action when hazards or violations are found.

What is a 'public health nuisance' in the context of environmental health law?

Answer: A condition, activity, or substance that is injurious or dangerous to public health, safety, or welfare and is subject to abatement

A public health nuisance is any condition, act, or substance that endangers public health or safety, constitutes an unreasonable interference with community welfare, and may be legally abated by authorities.

What is the chain of custody in environmental sample collection?

Answer: A documented record tracking the possession, handling, and transfer of a sample from collection through analysis to ensure legal admissibility and data integrity

Chain of custody is a documented tracking system recording every person who handled a sample and every transfer of possession, ensuring sample integrity and making results legally defensible in enforcement actions.

What is a 'risk assessment' in environmental health?

Answer: A systematic scientific process for characterizing the nature and magnitude of health risks from exposure to environmental hazards

Environmental health risk assessment is a four-step scientific process — hazard identification, dose-response assessment, exposure assessment, and risk characterization — that evaluates the probability and magnitude of adverse health effects from environmental exposures.

What are the four steps of the EPA's human health risk assessment framework?

Answer: Hazard identification, dose-response assessment, exposure assessment, and risk characterization

The EPA's four-step risk assessment framework consists of: hazard identification (what harmful effects can the substance cause), dose-response assessment (at what doses), exposure assessment (how much are people exposed), and risk characterization (combining these to estimate overall risk).

What is the difference between 'qualitative' and 'quantitative' risk assessment in environmental health?

Answer: Qualitative assessment describes risk in narrative terms; quantitative assessment provides numerical estimates of risk probability

Qualitative risk assessment characterizes risk descriptively (high, medium, low) while quantitative risk assessment generates numerical estimates (e.g., one additional cancer case per 100,000 exposed) using statistical models and dose-response data.
