“…Hal ini dikarenakan kondisi bebatuannya (Sekarningrum, 2017;Sekarningrum dan Sitam, 2018). Kondisi inipun dijumpai pada beberapa negara lain, dimana dengan mengkonsumsi air yang mengandung radon tinggi dapat berdampak pada kesehatan terutama pada paru-paru dan saluran penceranaan (Baskaran, 2016;et al, Sam, 2012;IAEA, 2014b;Mirhosseini, 2016; (National Research Council of The National Academies) NRCNA, 2006;Roba et al, 2010).…”

Konsentrasi radondapat mempengaruhi kondisi air yang biasa dikonsumsi masyarakat untuk kebutuhan sehari-hari. Hal ini berpotensi terhadap risiko kesehatan termasuk risiko kanker. Pengamatan potensi ini dilakukan pada sumber-sumber air yang biasa digunakan masyrakat. Sampel didapatkan dari sumber air di berbagai kampung yang biasa digunakan oleh masyarakat sekitar untuk keperluan sehari-hari. Pada penelitian ini sampel di tes menggunakan RAD 7 Electronic Radon detector yang telah disahkan oleh BATAN. Instrument ini digunakan untuk pengukuran radon dalam air, tanah, batuan maupun udara secara komprehensif. Konsentrasi radon pada air bervariasi di setiap sumber air. Konsentrasi radon telah diketahui yaitu 2030± 509 Bq/m 3 yang berasal dari sumber mata air kampung Cisalada dan 1140±393 Bq/m 3 yang berasal dari air sumur Kampung Giri Mulya dan 705±393 Bq/m 3 pada mata air daerah Kampung Pamucatan. Konsentrasi ini digunakan untuk menghitung konsentrasi rerata harian pada penduduk sekitar yang terpapar radon. Dosis rerata harian individu yang terpapar akibat konsumsi air mengandung radon adalah 5,0 × 10 -3 kg/ug/hari dan dosis efektif tahunan lebih rendah dari 0,1 mSv/tahun. Penelitian ini direkomendasikan sebagai acuan komprehensif yang dapat ditarik untuk kajian radiobiologi kesehatan dan toksisitas yang berhubungan dengan penyakit dan kualitas hidup masyarakat.

“…It is calculated that about 450 kg of solid waste as well as 50 m 3 of wastewater are released for every 200 kg of leather produced [4]. The tannery wastewater is well known as a complex liquid that contains high levels of organic loading, dissolved and suspended solids, saline, and other specific pollutants [5][6][7][8][9][10]. The wastewater also causes a series long-term affects to both water and soil [11][12][13].…”

Wastewater recycling technologies have been widely used in tanneries to reduce environmental impacts. However, only a few recycling methods have been developed for vegetable tanning processes due to limited knowledge of their wastewaters. In this study, the structures of the polyphenols in the larch tanning wastewater (LTW) and commercial larch tannin (CLT) were characterized with spectrographic and chromatographic analysis. Structures of these polyphenols were illustrated accordingly; their collagen reaction abilities were then tested with thermal analysis and visualized with a molecular docking software. Results showed that polyphenols in LTW and CLT were all procyanidins. However, average molecular weight of the polyphenols in LTW was 1104Da, in contrast to an obviously higher value for the CLT sample (3334Da). Meanwhile, the LTW presented obvious lower reactivity in the collagen-polyphenol reaction, including lower thermal stabilities and docking energies, fewer hydrogen bonds, and lower interaction energies. These results provide a hint for vegetable tanning wastewater recycling: because of these structural differences, reactivity of the polyphenols in wastewater are lower than the ones in commercial tannins. Therefore, before the recycling processes, polyphenols must be chemically modified in accordance with these structural differences.
