Risk assessment process groups

The first draft of the risk assessment reports are written by the Member States, which act as rapporteurs . Generally, one Member State acts as rapporteur for a prioritized substance or group of substances however, for some prioritized substances, more than one Member State can act as rapporteurs. The risk assessment process is coordinated by the ECB. Stakeholders are involved in the process through the Technical Committee for New and Existing Substances (TC NES). The Commission mediates the meetings, which attempt to reach consensus on the conclusions of the risk assessments. During the risk assessment process, the Scientific Committee on Health and Environmental Risks (SCHER) is requested to provide an opinion. 

Biomarkers are used at several stages in the risk assessment process. Biomarkers of exposure are important in risk assessment, as an indication of the internal dose is necessary for the proper description of the dose-response relationship. Similarly, biomarkers of response are necessary for determination of the no observed adverse effect level (NOAEL) and the dose-response relationship (see below). Biomarkers of susceptibility may be important for identifying especially sensitive groups to estimate an uncertainty factor. 

Risk characterization is the final step of the risk assessment process as laid out in the classic National Research Council report Risk Assessment in the Federal Government Managing the Process. In this step, the risk from a specific agent (chemical or physical) or group of agents in a particular setting is evaluated. This evaluation is based on a comparison of the results of the dose-response assessment for these agents with the outcome of the exposure... 

Sensitivity analysis is a method used to evaluate the impact of a single variable or a group of variables on the results from a model calculation. Sensitivity analysis may be used to determine which parameters in a calculation have the greatest influence on the results such that greater emphasis is placed on characterizing these parameters. Moreover, the results from these analyses may be used to identify ways to improve the overall predictive capability of the model by reducing the uncertainty in the parameters that have the greatest influence on the outcome. Sensitivity analysis may be applied to the risk assessment process in order to identify those variables that dominate risk estimates as well as those that are relatively unimportant. 

Risk characterization is the fmal step of the risk assessment process. It is the combination of the information from the previous stages, to estimate the incidence of an adverse effect in any population group. 

Before any pesticide can be authorized for use, its human and environmental safety have to be considered through risk assessment i.e., a comparison of hazard and exposure. A key element in the risk assessment process is the determination of the residue definition, i.e., the components of the residue resulting from the use of the pesticide that are considered to be relevant. Residues remaining on items for food and feed are identified in metabolism studies, in which the pesticide is radiolabeled to enable its fate and behavior to be followed. The metabolic pathways can be extremely complex but can be grouped into four distinct categories or phases [1],... 

The offshore oil and gas industry is characterised by a complex actor-network involving the oil companies, their supply chain on the upstream design and purchase side and on the downstream operations and maintenance subcontracting side, their workforce and its unions, the customers for the oil and gas, but also the public, the regulator and various interest and pressure groups. It is important in steps 1 and 2 of Renn s framework that all relevant actors in the system feel they are suitably engaged in the risk assessment process and feel that their firames and focuses and their concerns are treated seriously and suitably. 

After the initial risk categorization, the next step in the risk assessment process is the systematic identification of hazards associated with the project. Hazard discovery is the responsibility of all members of the system safety working group and others associated with the project. Other risk management responsibilities are dependent on the level of the risk, with decisions involving more significant risks reserved for senior commanders or managers. 

Reaching group consensus in the risk assessment process is a highly desirable goal. Sometimes, for what an individual considers obvious, achieving consensus is still desirable so that buy-in is obtained for the actions taken. 

Reach to each group of stakeholders and reach to each one for each step of the risk assessment process. 

The third stage of the risk assessment process involves identifying who could be harmed (i.e. who is at risk) and how. When considering who is at risk, it is important to consider all those who may be affected by the activity or be on the premises, as well as those who are directly involved. Groups of people who could be at risk may include the following ... 

Since 1970 tlie field of healtli risk assessment Itas received widespread attention witliin both tlie scientific and regulatoiy committees. It has also attracted tlie attention of the public. Properly conducted risk assessments have received fairly broad acceptance, in part because they put into perspective the terms to. ic, Itazard, and risk. Toxicity is an inlierent property of all substances. It states tliat all chemical and physical agents can produce adverse healtli effects at some dose or under specific exposure conditions. In contrast, exposure to a chemical tliat lias tlie capacity to produce a particular type of adverse effect, represents a health hazard. Risk, however, is tlie probability or likelihood tliat an adverse outcome will occur in a person or a group tliat is exposed to a particular concentration or dose of the hazardous agent. Tlierefore, risk can be generally a function of exposure and dose. Consequently, healtli risk assessment is defined as tlie process or procedure used to estimate tlie likelihood that...
