1-Hydroxypyrene is a human metabolite. It can be found in urine of outdoor workers exposed to air pollution.^[1]

Biochemistry

Experiments in pig show that urinary 1-hydroxypyrene is a metabolite of pyrene, when given orally.^[2]

A Mycobacterium sp. strain isolated from mangrove sediments produced 1-hydroxypyrene during the degradation of pyrene.^[3]

Highly significant differences and dose-response relationships with regard to cigarettes smoked per day were found for 2-, 3- and 4-hydroxyphenanthrene and 1-hydroxypyrene, but not for 1-hydroxyphenanthrene.^[4]
