Perbandingan kadar merkuri, kreatinin, dan urea pada pekerja industri di Kotagede dan Banguntapan, Yogyakarta sebagai indikator pencemaran

Abstract

Study from the Environmental Office of Yogyakarta, indicates in Kotagede found the pollution of mercury from the environment because of improper disposal of wastewater. This study aims to assess the levels of mercury, creatinine and urea in the serum and urine of people working in several industries in Kotagede and Banguntapan. Subjects of this study were 52 employees in several industries in Kotagede Yogyakarta with a range of ages between 20 - 71 years and length of work between 3 - 38 years. A total of 42 people with the age range was 21 - 63 years and the length of work between 1 - 20 years were taken from industrial employees in Bantul who have almost the same geographical conditions as Kotagede. Determination of mercury levels using the Atomic Absorption Spectrophotometry (AAS) method while the determination of urea and creatinine levels by a Dyasis kit. In Kotagede, there were 3 people (5.8%) with the average mercury serum of 0.217 ppb and no mercury in the urine was found in all subjects. In Banguntapan, one person (2.4%) had 0.200 ppb mercury serum and 6 people (14.3%) had an average mercury urine level of 0.395 ppb. Urine creatinine and urea levels in subjects from Kotagede were higher than those from Banguntapan (p<0.05), despite being on the normal range. The presence of mercury in several industrial employees in Kotagede and Banguntapan is still on the low range even though it was correlated to creatinine levels.
