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.See more on serc.carleton.eduBrief guide to a l methods ring lead in paint1) Test the paint for lead in situ using a chemical test kit. 2) Measure the amount of lead in paint in situ using a portable X-ray fluorescence (XRF) device. 3) Collect a paint sample and measure its lead content in a laboratory using various analytical techniques.
