Water pollution, other industry (% of total BOD emissions)

Definition: Industry shares of emissions of organic water pollutants refer to emissions from manufacturing activities as defined by two-digit divisions of the International Standard Industrial Classification (ISIC), revision 2: other (38 and 39). 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.

Description: The map below shows how Water pollution, other industry (% of total BOD emissions) varies by country. The shade of the country corresponds to the magnitude of the indicator. The darker the shade, the higher the value. The country with the highest value in the world is Singapore, with a value of 72.74. The country with the lowest value in the world is Moldova, with a value of 0.95.
