The glossary is compiled primarily for those scientists and others who now find themselves working in toxicology or requiring a knowledge of the subject, especially for hazard and risk assessment. Many medical terms are included because of their frequent occurrence in the toxicological literature.

Risk assessment
A scientifically based process consisting of four steps:
hazard identification,
hazard characterization,
exposure assessment and
risk characterization
(Source: Official Journal of the European Communities 2002 L 31 ) ...

risk assessment - methods used to quantify risks to human health and the environment.
run-off - precipitation that the ground does not absorb and that ultimately reaches rivers, lakes or oceans.

~: A process which estimates the likelihood that exposed people may have health effects.

~
Evaluation of the short-term and long-term risks associated with a particular activity or hazard; usually compared to benefits in a cost-benefit analysis.
RNA ...

~: 1. The use of factual information to define the nature and impact of an adverse effect on individuals or populations who have been exposed to hazardous materials and situations. 2.

~
Qualitative and quantitative evaluation of the risk posed to human health and/or the environment by the actual or potential presence and/or use of specific pollutants.(1) ...

~
A risk assessment looks at the chemicals detected at a site, the frequency and concentration of detected chemicals, the toxicity of the chemicals and how people can be exposed, and for how long.

~: See environmental ~.
RNA: The biochemical ribonucleic acid, which is important in translation of the genetic information of DNA into the synthesis of proteins. RNA also stores the genetic information of some viruses.

~ is the process of estimating the risk to health or environment of a product or work process by determining the possible extent of damage and the likelihood of that damage occurring. The goal is to produce "objective" data as a basis for making managerial or regulatory decisions.

~: An evaluation of risk which estimates the relationship between exposure to a harmful substance and the likelihood that harm will result from that exposure.

~ : A qualitative or quantitative evaluation of the environmental and/or health risk resulting from exposure to a chemical or physical agent (pollutant); combines exposure assessment results with toxicity assessment results to estimate risk.

~s
To determine how to clean up a contaminated property, an analysis known as a risk assessment may be performed in order to protect a nearby stream, aquifer , or both.

~
Careful consideration by competent persons of hazards associated with a task. Potential effect of each hazard, how serve it might be and likelihood of it occurring, should be considered to determine effort required to make site as safe as reasonably practicable.

~
With respect to Radiation Protection , risk assessment is essentially about assessing risk of radiation exposure in order to mitigate that exposure, ensuring doses are as low as reasonably practicable (ALARP ) and certainly below Dose Limits .

Baseline Risk Assessment
An analysis of the potential adverse health effects (current or future) caused by contaminant releases from a site in the absence of any actions to control or mitigate these releases. According to EPA, the baseline risk assessment can be used to determine whether: 1) A ...

Ecological Risk Assessment: The application of a formal framework, analytical process, or model to estimate the effects of human actions(s) on a natural resource and to interpret the significance of those effects in light of the uncertainties identified in each component of the assessment process.

Screening Risk Assessment: A risk assessment performed with few data and many assumptions to identify exposures that should be evaluated more carefully for potential risk.

Comparative Risk Assessment: Process that generally uses the judgement of experts to predict effects and set priorities among a wide range of environmental problems.

~ The process by which hazards and consequences are identified, characterised as to their probability and magnitude, and their significance assessed.

The information may come from site investigations (environmental sampling and studies), exposure assessments, risk assessments, biological monitoring or health effects studies.

However, it has rapidly become a mixed blessing without adequate risk assessment , severance tax or impact fee and oversight regulations. The fact that our environmental oversight personnel are dangerously under-staffed and under-resourced only adds to the problem.

The second of four steps in risk assessment, consisting of the analysis of the relationship between the total amount of an agent absorbed by a group of organisms and the changes developed in the group in reaction to the agent, ...

Assessment Endpoint- In ecological risk assessment, an explicit expression of the environmental value to be protected; includes both an ecological entity and specific attributed thereof. entity (e.g.

hazard evaluation A component of risk assessment that involves gathering and evaluating data on the types of health injury or disease (e.g., cancer) that may be produced by a chemical and on the conditions of exposure under which injury or disease is produced.

Biomonitoring-a direct measure of human exposure to substances. Biomonitoring involves measuring actual levels of exposure within the body which can help to make risk assessments far more accurate. (Mackinac Center for Public Policy) ...

assessment report = comparing the levels of risk and impact found during the analysis process with previously established risk criteria, producing a "measurement" or "level" of risk and deciding on an appropriate "response". The output of a risk assessment is a prioritised list of risks for ...

It is compatible with ISO 9001 and ISO 14001. It covers issues such as planning for hazard identification, risk assessment/control, OHS management, awareness and competence, training, communication, emergency preparedness and response, performance measuring and improvement ...
