Abstract:
Tanah Laut Regency is one of regencies in South Kalimantan that has coal mine
companies. Effects of coaldust exposure can cause oxidative stress and inflammation
process that influence endothelial function. Endothelial function is important to motherfoetus
circulation. This research’s goal was to analyze the effect of coaldust exposure to
mother’s blood pressure, haemoglobine level, and foetus’ heartbeat. The method used
observational analyzes with crossectional design. Respondents were at least 30 pregnant
women from area with coaldust exposure and without coaldust exposure. Respondents
were examined by doctor and midwive to check their bloodpressure, Hb level and foetus
heartbeat. Data were analyzed by comparative test. The results were 118.85 mmHg for
sistolic bloodpressure from coaldust exposure area and 120.93 mmHg for not-coaldust
exposure area (p=0.522); 73.67 mmHg for diastolic bloodpressure from coaldust
exposure area and 76.43 mmHg from not-coaldust exposure area (p=0.823); 11.533
gr/dL for Hb level from coaldust exposure area and 11.89 gr/dL from not-coaldust
exposure area (p=0.028); 143.21 x/minute for foetus heartbeat from coaldust exposure
area and 139.53 x/minute from not-coaldust exposure area (p=0.013). the conclusion was
coaldust exposure could effect mother’s Hb level dan foetus’ heartbeat, but could not
effect mother’s bloodpressure yet in Tanah Laut Regecy.
