ENVIRONMENTAL POLLUTION PARAMETERS

ENVIRONMENTAL POLLUTION PARAMETERSTo measure the level of contamination off site use parameter pollution. Parameters used as indicators of pollution (hint) pollution and contamination levels that have occurred.Pollution parameters include:1. Physical ParametersInclude measurement of color, taste, smell, temperature, turbidity, and radioactivity2. Chemical ParametersUsed to determine levels of CO2, pH, acidity, metal content, and heavy metals.


a. Measuring the pH of waterThe river water under natural conditions that have not been polluted stretch of pH 6,5 - 8.5. Because of pollution, water pH can be lower than 6.5 or higher than 8.5. Organic materials are usually organic causes water to become more acidic conditions. Lime causes water conditions become more alkaline (base). Thus, changes in the pH of the water depends on the material pencemarnya.
