Lesotho - Organic water pollutant

Organic water pollutant (BOD) emissions (kg per day)

The value for Organic water pollutant (BOD) emissions (kg per day) in Lesotho was 5,252 as of 2007. As the graph below shows, over the past 6 years this indicator reached a maximum value of 13,985 in 2002 and a minimum value of 3,132 in 2003.

Definition: Emissions of organic water pollutants are measured by biochemical oxygen demand, which refers to the amount of oxygen that bacteria in water will consume in breaking down waste. This is a standard water-treatment test for the presence of organic pollutants.

Organic water pollutant (BOD) emissions (kg per day per worker)

The value for Organic water pollutant (BOD) emissions (kg per day per worker) in Lesotho was 0.13 as of 2007. As the graph below shows, over the past 6 years this indicator reached a maximum value of 0.14 in 2001 and a minimum value of 0.13 in 2007.

Definition: Emissions per worker are total emissions of organic water pollutants divided by the number of industrial workers. Organic water pollutants are measured by biochemical oxygen demand, which refers to the amount of oxygen that bacteria in water will consume in breaking down waste. This is a standard water-treatment test for the presence of organic pollutants.
