Associations between airborne crude oil chemicals and symptom-based asthma.

ABSTRACT:

Rationale

The 2010 Deepwater Horizon (DWH) oil spill response and cleanup (OSRC) workers were exposed to airborne total hydrocarbons (THC), benzene, toluene, ethylbenzene, o-, m-, and p-xylenes and n-hexane (BTEX-H) from crude oil and PM_2.5 from burning/flaring oil and natural gas. Little is known about asthma risk among oil spill cleanup workers.

Objectives

We assessed the relationship between asthma and several oil spill-related exposures including job classes, THC, individual BTEX-H chemicals, the BTEX-H mixture, and PM_2.5 using data from the Gulf Long-Term Follow-up (GuLF) Study, a prospective cohort of 24,937 cleanup workers and 7,671 nonworkers following the DWH disaster.

Methods

Our analysis largely focused on the 19,018 workers
