What is Winkler’s Method and its use ?

The Winkler Method is a technique used to measure dissolved oxygen in freshwater systems. Dissolved oxygen is used as an indicator of the health of a water body, where higher dissolved oxygen concentrations are correlated with high productivity and little pollution. This test is performed on-site, as delays between sample collection and testing may result in an alteration in oxygen content.

Its use to Dissolved oxygen analysis.

Dissolved oxygen analysis can be used to determine:

the health or cleanliness of a lake or stream,

the amount and type of biomass a freshwater system can support,

the amount of decomposition occurring in the lake or stream.the health or cleanliness of a lake or stream,
