My answer would be "Yes". IMHO, there is no reason why you should not broaden the term of environmental impact assessment to include working environments. I think the title you are proposing describes your project clearly.

The line in quotation marks in the second paragraph is grammatically incorrect and therefore confusing. Your phrasing of the same activity in the first paragraph is better. Beyond the proposition (of versus on) the first paragraph is also clearer in specifying 'working' environment.

I would give a slightly different opinion, perhaps not applicable to your circumstances on how you use the term.  Our use of Environmental Impact Assessment, Environmental Assessment and Environmental Impact Statement is primarily founded in the US National Environmental Policy Act (NEPA) legislated about 1969.   It involves an interdisciplinary analysis (using at time a team of technical specialists) to address various aspects of a proposed action, considers effects of various alternatives, reviewed by public and interests, and considered in decision making or review.  The use you suggested is a generic use of the terms, and that still may be appropriate for circumstance, but typically for research which is apt to be directed to specific areas, and may not consider all the environmental impacts to resources (soil, water, air, wildlife, etc.), social, economic, etc.  But as author, researcher, you will have to decide if the research fits how this term is used and applied for the circumstance, and conveys the message and intent of your subject to those who will be reading it.  

Easily, 

EIA is for research in which results are impact (global warming potential etc ).

what i know is that the EIA study is a full study of all the impacts in the environment including the humans so what you wanted to do is a very small part of EIA study. I would prefer you to specify more your title like e.g (impact of exposure to toxic chemical on Workers of specific industry)

it will be better to specify the toxic chemical exposed by workers because there are many!

I tend to agree with Kawthar. EIA usually refers to the installation of industrial facilities. Your case is much more specific and restrictive. The title should portray this.

Environmental Impact Assessment is useful topic and of Global interest and  data will be useful in public interest as well as to authority responsible towards Environmental pollution control. Keep on study and communicate.

A capsule definition of the term lifted from my thesis... "EIA is a decision making process, activity and documentation that provides the evaluation of direct and indirect consequences of proposed development by predicting, evaluating and mitigating the bio- geo physical, social and cultural effects of such action on man’s health and environment which could be short term, medium term and long term" ....

As Williams F. stated, the term is  generic. Your study should rather specify the aspects you are concentrating;  more likely to be done on your statement of scope  in simple terms; such that when you are looking at environmental impacts of a particular action, you state clearly as it impacts what? health, social well- being, economic aspects of your chosen location. With that your variables can easily be mapped and articulated. 

Because I have really seen some articles quoting EIA of certain action... but mostly fail to do justice to the topic as it has been highlighted. 

Hi!

In my opinion, the important thing is to clearly state what we mean by "environment" and what we mean by "impacts". The first term is often used in very different situations, without specifying the area of direct influence and what is the indirect area of influence of a project.

The term "environmental impact" is generally misused because it is used to analyze environmental RISKS, which is a different thing, since "impacts" refer to changes that have already occurred.

There are millions of Environmental Impact Assessments, they are all different, very few are really useful as studies to "predict" modifications produced by a project about the environment, on society. They are always logic exercises, which when well done ... are accepted by society.

Environmental impact Assessment (EIA) is an exercise carried out by regulatory bodies for instance like NEMA-national environmental Management Authority in Kenya before any project is carried out. it's an exercise carried out to ascertain risks of a project on the environment, people and so on. As the project is carried out, environmental audits (EA) are carried out to ascertain whether the project is following regulations set out in the EIA report

If the project that will be covered by an EIA is affecting people, living in the area, then it is called SEIA (Social & Envirornmental Impact Study). 

I would suggest you don't use the word Environmental Impact Assessment (EIA). EIA incorporates the assessment of impacts of any  project on both biophysical and socioeconomic components of the environment. Moreover, EIA has to comply with the legal provisions of the country where the project is to be undertaken. Your research, as you elaborated in the question, doesn't seem to qualify for EIA

First of all, poor health and safety management as financial cost. The illness is caused by exposure to toxic chemical at work place are health and safety management issues. Which integrates into the organization environmental management system. Why not study into the health and safety, and environmental management issues of the organization. This will help to identify the health and safety and environmental management issues in the organization and the financial lost of the workers and their employer.

Environmental Impact Assessment (EIA) is used when the project/proposal under consideration is believed to have some kind of impact, positive or negative on the environment. It is a general term including biophysical and socioeconomic issues.

Hello Yasodhagayathri, 

EIA is a process of evaluating the likely environmental impacts of a proposed project or development, related to socio-economic, cultural and human-health impacts. It examines beneficial and adverse consequences of the proposed projects.

In short, we implement EIA to: 

1. Ensure that natural resources are used appropriately and efficiently.

2. Identify appropriate measures for mitigating the potential negative impacts of the project.

3. Protect human health and safety.

4. Avoid irreversible damages to the environment.

5. Safeguard ecosystem components.

Moreover, the EIA framework does not stop after the implementation of the proposed projects. It rather continues following up the aforementioned impacts of the project. 

With best regards,

Hailemariam

EIA is not the appropriate term to use in your case. EIA applies to major development projects requiring a variety of technical and legal framework. However, I suggest that you classify it as 'occupational hazards due to environment' or health, safety & environment as earlier suggested.

I fully agree with @Omowunmi Fred-Ahmadu

Environmental Impact Assessment (EIA) is carried out to forecast the likely effects of any proposed activity (such as industry, highways/rods, railway lines, airports, development projects etc.) on the environment (ambient air quality, ambient water quality, ambient noise level, ground water resources, land/ soil quality, forests/vegetation etc.). EIA is generally used for permission or rejection of the activity depending upon its findings. Hope, the above explanation would minimise your confusion. It appears, you are misinterpreting the environmental assessment. However, I like to know, what you exactly mean by the ‘environment’ as far as your proposed work/research is concerned.

The term "EIA" is not appropriate in your case.  It would be more appropriate if you would consider using the following term: "The economic impact of working environment on workers' health and productivity, exposed to toxic chemicals "

Thank you all for the valuable answers. Thank you so much
