A rapid increase in the concentration of hydrogen peroxide was observed when samples of natural surface and ground water from various locations in the United States were exposed to sunlight. The hydrogen peroxide is photochemically generated from organic constituents present in the water; humic materials are believed to be the primary agent producing the peroxide. Studies with superoxide dismutase suggest that the superoxide anion is the precursor of the peroxide.
当来自美国各地的天然地表水和地下水样本暴露在阳光下时，观察到过氧化氢的浓度迅速增加。过氧化氢是由水中存在的有机成分光化学产生的;腐殖质被认为是产生过氧化物的主要物质。超氧化物歧化酶的研究表明，超氧阴离子是过氧化物的前体。
