Cempaka District is the largest traditional gold mining site in South Kalimantan Province. The purpose of this study was to identify levels of mercury (Hg), degree of acidity (pH) and health risk factors (age, years of service and completeness of PPE) in PETI workers in Cempaka District. The method used in this research is an observational method which is quantitative in nature with a cross-pontong approach, with a proportional difference test method. Sampling was carried out in the upstream and downstream areas. Measurement of water mercury levels was measured by means of Cold Vapor Atomic Absorption Spectrophotometry (CV-AAS) at the Industrial Research and Standardization Center (BARISTAND) in Banjarbaru City. As for the health risk factor variables using the method of observation and interviews with a questionnaire. The research sample was 40 active PETI workers. The results showed that the quality of water with mercury content exceeds the threshold, for the parameter of acidity (pH) within the norm limit of 6-9. Meanwhile, for health risk factors, PETI workers are mostly old, have worked ≥ 5 years and do not completely use PPE. Suggestions are to pay attention not to dispose of waste mercury (Hg) content into rivers. Keywords : Mercury levels ( Hg ); degrees acidity ( pH ); health risk factors; the workers Abstrak Kecamatan Cempaka merupakan tempat penambangan emas tradisional yang terbesar di Provinsi Kalimantan Selatan. Tujuan penelitian ini adalah untuk mengidentifikasi besar kadar merkuri (Hg), derajat keasaman (pH) dan faktor risiko kesehatan (Umur, masa kerja dan kelengkapan APD) pada pekerja PETI di Kecamatan Cempaka. Metode yang digunakan dalam penelitian ini yaitu metode observasional yang bersifat kuantitatif dengan pendekatan potong lintang, dengan metode uji-beda proporsi. Pengambilan sampel dilakukan pada daerah hulu dan hilir. Pengukuran kadar merkuri air diukur dengan alat Cold Vapor Atomic Absorption Spectrophotometry (CV-AAS) di Balai Riset dan Standarisasi Industri (BARISTAND) di Kota Banjarbaru. Sedangkan untuk variabel faktor risiko kesehatan menggunakan metode pengamatan dan wawancara dengan kuosioner. Sampel penelitian adalah pekerja PETI yang aktif sebanyak 40 responden. Hasil penelitian menunjukkan kualitas air dengan kandungan kadar merkuri melebihi ambang batas, untuk parameter derajat keasaman (pH) dalam batas norma sebesar 6-9. Sedangkan untuk faktor risiko kesehatan, pekerja PETI lebih banyak berumur tua , masa kerja ≥ 5 tahun dan tidak lengkap menggunakan APD. Saran untuk memperhatikan untuk tidak membuang limbah kandungan kadar merkuri (Hg) ke aliran sungai. Kata kunci : Kadar Merkuri (Hg); Derajat Keasaman (pH); Faktor Risiko kesehatan; Pekerja PETI

The mercury content of 117 mushroom samples corresponding to 8 different species collected in the Sierra of Cordoba (Spain) was determined by cold vapor atomic absorption spectrophotometry. The results obtained showed that the mercury content differed according to the species and to the anatomical group examined. Samples of Psalliota xanthoderma showed maximum levels (0.669–0.210 mg/kg, fresh weight) and the ratio cap/stem obtained is 1.32. The concentration levels were compared to literature data and the contribution of mushrooms to the daily intake of mercury in Spain was evaluated.

Abstract The combustion procedure previously described for the determination of mercury in coal by cold vapor atomic absorption spectrophotometry has been modified to permit samples to be analyzed more rapidly and with better precision. A coefficient of 8.3% was obtained for the analysis of 7 samples containing 0.1 ppm mercury. In addition a greater variety of types and particle sizes of coal can be analyzed by the modified procedure.
