The four-step risk assessment process. Environmental hazard identification is the first step in environmental risk assessment, which is the process of assessing the likelihood, or risk, of adverse effects resulting from a given environmental stressor. [6]
The Canadian Environmental Assessment Act 2012 (CEAA 2012) [27] "and its regulations establish the legislative basis for the federal practice of environmental assessment in most regions of Canada." [28] [29] [30] CEAA 2012 came into force July 6, 2012 and replaces the former Canadian Environmental Assessment Act (1995). EA is defined as a ...
Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. [1] [2]
Preliminary Risk Assessment – Also known as a Phase 1 Preliminary Risk Assessment, or Desk Study, [7] this work involves the collection and review of many different sources of information including: local authority registers, environmental databases, geological maps, and historic records. A site walkover is usually also undertaken to identify ...
Environmental Assessment has little to do with the subject of hazardous substance liability, but rather is a study preliminary to an Environmental Impact Statement, which identifies environmental impacts of a land development action and analyzes a broad set of parameters including biodiversity, environmental noise, water pollution, air ...
Ecological assessment (EA) implies the monitoring of ecological resources, to discover the current and changing conditions. EAs are required components of most hazardous waste site investigations. Such assessments, in conjunction with contamination and human health risk assessments, help to evaluate the environmental hazards posed by ...

'Exposure assessment' and 'exposure analysis' are often used as synonyms in many practical contexts. Risk is a function of exposure and hazard. For example, even for an extremely toxic (high hazard) substance, the risk of an adverse outcome is unlikely if exposures are near zero. Conversely, a moderately toxic substance may present substantial ...
