Relationship Patterns of Rest with Blood Chromium Levels of Workers at Leather Industry Magetan

Operational processes in the leather industry use chemicals. One of them uses chromium sulfate as a tanner. Various studies have shown that there are health problems in tanning workers if exposed to chromium. The purpose of this study is to find out the relationship between resting patterns and levels of chromium in the blood of workers. Using a cross sectional design, there were 10 workers studied specifically handling the tanner’s process with a minimum ten-year tenure. The results showed that all respondents had chromium levels exceeding the standard according to Jantzen namely 1.6 μg/L-5.1 μg/L. The pattern of rest includes staying up late has a weak correlation with the levels of chromium in the blood, total rest also has a weak correlation with the levels of chromium in the blood, as well as rest at night. The metabolic process in the body plays a role in removing chromium toxins as long as workers carry out adequate resting activities. In conclusion, exposure to chromium during the tanning process causes high levels of chromium in the blood. The existence of a weak correlation between the break pattern variables shows that these variables do not affect significantly. Suggestions that workers use personal protective equipment so as to minimize exposure to chromium and take advantage of rest periods optimally.
