Are you concerned about the impact of environmental factors on your health? The Environmental Health Impact Assessment (EHIA) Calculator is here to help you determine the potential health risks associated with the environment around you.

Introduction
The EHIA calculation formula is simple yet effective, as it takes into account the four most important elements of environmental health: health, overall well-being, pollution level, and environmental factors. The formula is as follows:
EHIA = (H + O + P + E) / 4
Where H is for health, O for overall well-being, P for pollution level, and E for environmental factors.
Categories and Interpretation
EHIA results are categorized into five levels, ranging from Excellent to Poor, depending on the calculated score. The following table outlines the different categories, types, range, and interpretation for EHIA calculations:
| Category | Type | Range | Interpretation |
|---|---|---|---|
| Health | Physical | 0 – 100 | Excellent – Poor |
| Overall Well-being | Emotional | 0 – 100 | Excellent – Poor |
| Pollution Level | Air Quality | 0 – 500 | Excellent – Hazardous |
| Environmental Factors | Land Use | 0 – 100 | Excellent – Poor |
Examples of EHIA Calculations
Let’s see how EHIA works in different scenarios. Here are some examples of EHIA calculations for different individuals:
| Person | Health | Overall Well-being | Pollution Level | Environmental Factors | EHIA |
|---|---|---|---|---|---|
| John | 75 | 80 | 120 | 60 | (75 + 80 + 120 + 60) / 4 = 83.75 |
| Jane | 90 | 70 | 70 | 90 | (90 + 70 + 70 + 90) / 4 = 80 |
| Jack | 60 | 50 | 400 | 20 | (60 + 50 + 400 + 20) / 4 = 132.5 |
As you can see, John and Jane have a better EHIA score than Jack. Poor Jack! However, the EHIA score is not the end-all-be-all of environmental health assessments, and it’s important to consider other factors when evaluating potential health risks.
Different Ways to Calculate EHIA
There are different ways to calculate EHIA, each with its own advantages and disadvantages. Here’s a more detailed breakdown of the different methods used to calculate EHIA:
- Qualitative analysis: This method of analysis is easy to understand but is subjective and prone to errors.
- Quantitative analysis: This method is objective but complex, and requires extensive data analysis to be effective.
- Combined analysis: This method combines both qualitative and quantitative analysis, providing an accurate and easy-to-understand assessment of potential health risks. However, this method can be time-consuming.
Evolution of EHIA Calculation
EHIA calculation has evolved over time, from a simple checklist to a more comprehensive quantitative analysis. In the 1970s, EHIA was conducted using a simple checklist, whereas in the 1980s, qualitative analysis was introduced. In the 1990s, quantitative analysis became the norm, and in the 2000s, combined analysis was introduced, providing a more accurate and comprehensive assessment of environmental health. In the 2010s, AI-powered analysis was introduced, allowing for even more complex data analysis.
Limitations of EHIA Calculation
While EHIA is a useful tool for assessing potential health risks associated with environmental factors, it’s not always accurate due to several limitations. Here are some of the most significant limitations:
- Limited data availability: EHIA heavily relies on data availability, which is not always comprehensive. This can lead to inaccurate assessments of potential health risks.
- Subjectivity: Qualitative analysis is subjective and prone to errors. This can lead to inaccurate assessments of potential health risks.
- Unpredictability: Environmental factors can change rapidly, making EHIA calculation less reliable. This can lead to inaccurate assessments of potential health risks.
It’s important to keep these limitations in mind when evaluating potential health risks associated with environmental factors.
Alternative Methods for Measuring EHIA
There are alternative methods for measuring EHIA, each with its own pros and cons. Here’s a more detailed breakdown of the different methods:
- Health Risk Assessment: This method provides a comprehensive assessment of health risks associated with environmental factors but is time-consuming.
- Environmental Monitoring: This method provides real-time data on environmental factors but has a limited scope.
- Community Participation: This method is inclusive but can be subjective.
It’s important to weigh the pros and cons of each method when evaluating potential health risks associated with environmental factors.
