14529 IUPAC Gold Book - cold condensation theory 10.1351/goldbook.14529 14529 current 1 Theory that pollutants with high vapor pressure, e.g., mercury or persistent organic pollutants (POPs), in the air will condense onto soil, water, and biota at cool temperatures. Consequently, the ratios for POP concentrations in the air and on condensed phases decrease as one moves from warmer to cooler climates. persistent organic pollutants https://goldbook.iupac.org//terms/view/14909 soil https://goldbook.iupac.org//terms/view/15036 PAC, 2009, 81, 829.
