Abstract :
Workshop workers are a group of people who are at risk of exposure to
carbon monoxide (CO). This risk increases with the habit of workshop workers, the
majority of whom are active smokers. Hemoglobin in the blood will more easily
bind to CO to form carboxyhemoglobin (COHb) than with oxygen. The purpose of
this study was to determine COHb levels in the blood of motorcycle repair workers
at Sidoharjo Wonogiri Market.
Thisresearch is a descriptive research with quota sampling technique. Blood
samples were taken from 10 respondents with criteria for active smokers. Active
smokers include light, moderate, and heavy smokers. Examination of COHb levels
using the Hinsberg Lang method using a UV-VIS spectrophotometer.
From the examination, it was found that the lowest COHb level of the
respondents was 2.89% with one sample being a passive smoker. Meanwhile, nine
samples of active smokers had COHb levels in the range of 4.14%-9.48%, where
the levels were above the normal limit (>3.5%).
The conclusion of this study is that passive smokers have COHb levels
within normal limits, while all samples of active smokers have COHb levels above
normal.
