“…The 206 Pb/ 204 Pb versus 208 Pb/ 204 Pb (Figures and a) and the Pb triple isotope ( 207 Pb/ 206 Pb versus 208 Pb/ 206 Pb, Figure S1) plots reveal that the nonwinter samples are similar to IGP aerosols, whereas the winter sample composition more closely resembles that of the Himalayan biomass (Figure , a), which can be considered as a proxy of local soil composition as biomass gets its signature from the soil in which it grows. , Similarly, ε Nd values of nonwinter aerosols are similar to the IGP composition, whereas the winter sample compositions more closely resemble those of Northwestern Himalayan mountainous regions (Karakoram, Hindu Kush, Indus river origin) located to the west of Harsil (Table S7).…”

The Indo-Gangetic Plain (IGP) is one of the most highly polluted regions of the world, yet the temporal pattern of transport of anthropogenic aerosols from this region to the Himalayas is poorly constrained. On the basis of the seasonal variation of planetary boundary layer heights, air mass back trajectory analysis, and year-long time-series data for 208Pb/204Pb, 207Pb/204Pb, 206Pb/204Pb, and 143Nd/144Nd from aerosols collected over a high-altitude station, we demonstrate that anthropogenic Pb transport to the glacierized catchment has a seasonal pattern. The Pb isotope data reveal that during winter, the thinned boundary layer traps up to 10 ± 7% more coal-derived Pb in the IGP. In contrast, in nonwinter months, a thicker boundary layer and enhanced subtropical westerly winds result in efficient Pb transport to the Himalayas. As Pb isotope ratios are robust conservative chemical tracers and Pb is predominantly derived from anthropogenic sources, these observations suggest that enhanced transport of anthropogenic aerosols to the glacierized catchment of the Himalayas coincides with higher near-surface temperatures in the summer, creating positive feedback that enhances melting. Our results further suggest that >50% of Pb in the Himalayan aerosols originates from the resuspension of historic Pb derived from phased out leaded gasoline, highlighting the importance of legacy Pb stored in the Indo-Gangetic Plains.

“…Deposisi atmosfer Hg(II) menjadi sumber utama masuknya Hg ke lingkungan permukaan (Amos et al, 2012). Selain kegiatan penambangan, emisi Hg juga diketahui berasal dari wet flue gas hasil desulfurisasi air limbah yang menggunakan bak aerasi (Hsu, Atkinson, Chung, & Hsi, 2021), maupun emisi pembangkit listrik bahan bakar batubara (coal-fired power plant) (Li et al, 2021).…”

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)
