“…Hingga saat ini, belum tersedia baku mutu Hg di udara ambien di Indonesia. Beberapa kajian mengenai keberadaan Hg di udara ambien diketahui menggunakan metodologi berbeda (Asmarani, Abbas, & Sulaeman, 2021;Febrion & Falah, 2018;Huang, Lyman, Hartman, & Gustin, 2014;Yulinawati, Zulaiha, Pristianty, & Siami, 2019). Kegiatan ini bertujuan untuk mendapatkan data konsentrasi Hg di kawasan perkantoran Serpong dan selain itu data juga dapat digunakan sebagai dasar untuk penyusunan standar maupun baku mutu.…”

Merkuri (Hg) adalah logam alami yang dapat menyebabkan efek negatif terhadap kesehatan manusia dan mahluk hidup lainnya. Kajian ini merupakan bagian dari kegiatan pengembangan yang dilakukan oleh Laboratorium Merkuri dan Metrologi Pusat Standardisasi Instrumen Kualitas Lingkungan Hidup (PSIKLH). Tujuan kegiatan ini adalah untuk mendapatkan informasi mengenai konsentrasi Hg di udara ambien di Serpong sebagai bahan pendukung dalam penyusunan metode standar atau baku mutu Hg di udara ambien. Sampling dilakukan pada tanggal 4 Mei 2021 sampai 28 September 2022, setiap 1 (satu) minggu sekali secara kontinu dengan 3 (tiga) rangkaian alat sampling pada waktu yang bersamaan. Lokasi penempatan alat sampling berada di Lantai 2 Gedung 210 PSIKLH Serpong-Tangerang Selatan sesuai standar SNI 19-7119.6-2005. Metode sampling menggunakan pompa vakum dengan laju alir 0,5 L/menit selama 24 jam ke media adsorben Hg yang terbuat dari emas (Au) sehingga terjadi amalgamasi. Analisis Hg dilakukan menggunakan teknik thermal desorption yang dipanaskan pada suhu 800◦C dimana Hg dilepaskan dari kolom emas menjadi uap Hg, kemudian dideteksi menggunakan mercury analyzer Nippon Instruments Corporation (NIC) tipe MA-3000. Hasil kajian menunjukkan rata-rata konsentrasi Hg di udara ambien tahun 2021 relatif kecil (11,7 ng/m3), dan tahun 2022 sebesar 25 ng/m3, berada di bawah nilai acuan yang ditetapkan oleh WHO (2017) untuk udara ambien yang ditetapkan oleh WHO (300 ng/m3). Hal ini cukup menarik karena konsentrasi Hg di Serpong lebih tinggi dibandingkan dengan kajian-kajian di wilayah urban Da Nang, Vietnam (3,86 ng/m3), Nanjing, China (7,9 ng/m3), Guiyang, China (9,72 ng/m3), Taoyuan, Taiwan (2,6 ng/m3), dan di wilayah background Welgegund, Afrika Selatan (1,68 ng/m3)

“…Chronic mercury poisoning is common in Since 2002 https://oamjms.eu/index.php/mjms/index humans living near mines [9], [10]. Poisoning cases in Indonesia occurred in several places, such as the case of Buyat Bay; from an examination conducted on four people living around Buyat Bay, it was found that the mercury content in the blood exceeded the threshold [11].…”

BACKGROUND: Gold mining, especially by the community, causes many problems. One of the problems is the increase in mercury pollution. The amalgamation technique involving mercury in the gold processing process is still widely used by miners and has the potential to threaten the health of workers and the surrounding community. AIM: This study aimed to identify mercury levels in soot at the location of a traditional gold processing plant in Paya Seumantok Village, Krueng Sabee District, Aceh Jaya District. METHODS: This research was conducted at the Environmental Quality Analysis laboratory, Chemical Engineering Department, Syiah Kuala University, Banda Aceh, in May–August 2021. The sample in this study was soot caught on cloth attached to the gold kiln location by amalgamation using the quadrant method. The soot sample was obtained from the people’s gold processing unit in Gampong Paya Seumantok, Krueng Seabee District; then, the fabric sample containing soot was destroyed using HNO3 in the microwave. Measurement of mercury levels, using AAS Perkin-Elmer Analyst 600, equipped with Graphite Furnace (AAS) Technique. RESULTS: The results of the identification show that the mercury level in the first stage of measurement found the highest mercury concentration at a distance of 10 cm with a concentration of 41.90 (±21.64) g-Hg/g, a distance of 5 cm was obtained at 28.71 (±11. 0.98) g-Hg/g, and at a distance of 15 cm obtained 28.20 (±2.85) g-Hg/g. Furthermore, in the measurement of samples in stages 2 and 3, the mercury concentration in soot is influenced by distance, where the closer the distance, the higher the mercury concentration. Stage 2 measurement at a distance of 5 cm, the mercury concentration obtained is 26.84 (±21.05) g-Hg/g, a distance of 10 and 15 cm each has a concentration of 9.25 (±1.26) g-Hg/g and 9.91 (±3.59) g-Hg/g, and in the third stage of the test, the highest concentration located at a distance of 5 cm with a concentration of 20.27 (±3.57) g-Hg/g. CONCLUSION: The average value of mercury concentration in soot obtained far exceeds the threshold set by the World Health Organization, which is 1 g-Hg/gram. Mercury levels that have exceeded the threshold need to be filtered in an enclosed space before the smoke from burning gold spreads into the free air.
