Relationship between ambient black carbon and daily mortality in Tehran, Iran: a distributed lag nonlinear time series analysis.

ABSTRACT:

Purpose

The aim of the present study was to investigate the effect of short-term exposure to ambient black carbon (BC) on daily cause-specific mortality, including mortality due to respiratory, cardiovascular, ischemic heart and cerebrovascular diseases in Tehran, Iran.

Materials and methods

Daily non-accidental death counts, meteorological data and hourly concentrations of air pollutants from 2014 to 2017 were collected in Tehran. A distributed lag non-linear model was used to assess the association between exposure to BC and daily mortality.

Results

The mean daily BC concentration during the study period was 3.96 ± 1.19 µg/m³. The results indicated that BC was significantly associated with cardiovascular, ischemic heart disease, and cerebrovascular mortal
