Environmental Risk Assessment

 

What should I know about the environmental risk assessment? Before understanding what is an environmental risk assessment, let’s first familiarize with the words risk and hazard. These two terms have very different meanings and cannot be interchangeable but you probably know the meaning of each one:

A hazard is an inherent potential for someone or something to cause harm

Hazards can include machines, substances, energy forms and even the way you do your job.

A risk is a possibility that an actual harm will be done by the realization of a situation where a hazard appears.

We have a little equation to describe the relation between risk and hazard better: Risk = Exposure x Hazard

And the word environmental means physical surroundings like land, wildlife, air, plants. This definition, used in the Environmental Protection Act 1990 is that the environment consists of any,all of the following air, water and land.

Listing each keyword by itself, now the environmental risk assessment means covering the risk to all ecosystems including the people, exposed or impacted, these media. This term doesn’t normally cover the risks to general public from exposure to the work place or consumer products where there will be applied different legislation principles.

There are some specific stages in which you carry out an environmental risk assessment:

1.Hazard identification – Like the name suggests, we will identify the proper situation that could lead to harm

2.Identification of the consequences that would be produced if the hazard will occur  – Hazard identification

3.We will next estimate the magnitude of the consequences – Also known as release assessment, this step includes the consideration of the temporal and spatial scale of the consequences.

4.Another step is the estimation of the consequence probability – 3 components include this : the probability of the receptors to be exposed to the hazard, the simple presence of the hazard and the harm that will result from exposing to the hazard ( also known as consequence or exposure assessment ).

5.The significance of a risk evaluation – this step is the product of the likelihood of the hazard to be realized and also if it realizes what are the consequences

Quite a popular concept in an environmental risk assessment is : source – pathway – receptor.

Using this model of pathway between a hazard source plus a receptor, is investigated. The result of the receptor coming into contact with the resource would be the linkage and if no pathway exists, then there is no risk.

But if there is a change that the pathway exists, linking the source to the receptor , then in this case the consequences can be determined.

We will take an example:

Example of source             Example pathway                 Example receptor

Contaminated soil              Air                                       People

In the end of a risk assessment process, the existing controls should always be recorded and other measures may be need to be taken into consideration in order to reduce or even wipe out the risks that we identified.

And with this concludes a simple environmental risk assessment introduction and we hope has cleared some questions in your head.
