Note:
This calculator helps determine the concentration of a contaminant in air or water, which is crucial in environmental safety, occupational health, and public health risk assessments.
Parameters Explained:
- Amount of Contaminant (A): The total quantity of a pollutant or hazardous substance present in the air or water, typically measured in milligrams (mg) or grams (g).
- Volume of Air/Water (V): The total volume of the medium (air or water) in which the contaminant is dispersed, measured in liters (L) or cubic meters (m³).
Typical Concentration Ranges:
- Air: Safe levels of air pollutants (e.g., dust, gases) often range from 0.1 to 1 g/m³. High levels (above 1 g/m³) may indicate hazardous air quality.
- Water: Drinking water contaminants are typically measured in mg/L. Safe levels are usually below 1 mg/L, while levels exceeding 10 mg/L may pose health risks.
How It Is Used in Real Life:
- Workplace Safety: Industries use this calculation to monitor air quality and ensure workers are not exposed to hazardous chemical levels beyond safe limits.
- Environmental Monitoring: Used by environmental agencies to assess pollution levels in water bodies and air to implement control measures.
- Public Health: Helps health departments evaluate the risk of contaminant exposure in drinking water supplies and indoor air.
- Industrial Hygiene: Supports determining safe handling procedures for chemicals in manufacturing and laboratory settings.
