Tonga - Water pollution
Water pollution, clay and glass industry (% of total BOD emissions)
Water pollution, clay and glass industry (% of total BOD emissions) in Tonga was 2.22 as of 2004. Its highest value over the past 13 years was 7.63 in 2001, while its lowest value was 2.22 in 1992.
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: stone, ceramics, and glass (36). 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.
