Mendaki gunung merupakan kegiatan olahraga sekaligus rekreasi yang dalam situasi tertentu mengakibatkan tumpukan sampah tertinggal di berbagai lokasi (puncak, sekitar kemah, dan sepanjang lintasan). Kegiatan bernama Operasi Bersih Sampah Gunung Cikuray bertujuan membersihkan lokasi terjangkau dari sampah, khususnya yang berbahan plastik. Kegiatan dilaksanakan pada Sabtu-Ahad, 29-30 Agustus 2020 melalui Kiara Janggot, Kota Garut, Jawa Barat. Kegiatan diikuti 52 orang dengan peserta termuda berusia 9 tahun dan tertua 45 tahun, 38 lelaki dan 14 perempuan. Sampah yang berhasil dikumpulkan dan dibawa ke kaki gunung berjumlah sekitar 60 kantong ukuran 3kg dan 15 karung ukuran 20 kg, total sekitar 400 kg. Jenis sampah umumnya botol  (botol plastik berisi urin, botol AMDK, botol minuman keras, tutup botol), pembalut, tisu, bungkus permen, bungkus mi instan, dan puntung rokok. Kegiatan ini sangat bermanfaat, selain bagi kebersihan, kesehatan, dan kelestarian lingkungan, juga bagi individu yang mengikuti kegiatan, baik secara fisik maupun mental.---Mountain climbing is a sport as well as recreational activity which in certain situations results in piles of garbage left in various locations (at the top, around the camp, and along the trails). The activity called Operation Mount Cikuray Garbage Cleanup aims to clean up affordable locations from rubbish, especially those made of plastic. The activity was carried out on Saturday-Sunday, 29-30 August 2020 through Kiara Janggot, Garut City, West Java. The activity was attended by 52 people with the youngest participants aged 9 years and the oldest 45 years, 38 men and 14 women. The garbage collected and brought to the foot of the mountain is around 60 and 15 20 kg sacks, a total of about 400 kg. Types of waste are generally bottles (plastic bottles containing urine, bottled drinking water bottles, liquor bottles, bottle caps), sanitary napkins, tissue wrappers, instant noodle wrappers, and cigarette butts. This activity is very beneficial, in addition to cleanliness, health and environmental sustainability, as well as for individuals who participate in the activity, both physically and mentally.

Inefficient and non-environmentally friendly absorbent production can lead to much resource waste and go against low carbon and sustainable development. A novel and efficient Mg-Fe-Ce (MFC) complex metal oxide absorbent of fluoride ion (F−) removal was proposed for safe, environmentally friendly, and sustainable drinking water management. A series of optimization and preparation processes for the adsorbent and batch experiments (e.g., effects of solution pH, adsorption kinetics, adsorption isotherms, effects of coexisting anions, as well as surface properties tests) were carried out to analyze the characteristics of the adsorbent. The results indicated that optimum removal of F− occurred in a pH range of 4–5.5, and higher adsorption performances also happened under neutral pH conditions. The kinetic data under 10 and 50 mg·g−1 were found to be suitable for the pseudo-second-order adsorption rate model, and the two-site Langmuir model was ideal for adsorption isotherm data as compared to the one-site Langmuir model. According to the two-site Langmuir model, the maximum adsorption capacity calculated at pH 7.0 ± 0.2 was 204 mg·g−1. The adsorption of F− was not affected by the presence of sulfate (SO42−), nitrate (NO3−), and chloride (Cl−), which was suitable for practical applications in drinking water with high F− concentration. The MFC adsorbent has an amorphous structure, and there was an exchange reaction between OH− and F−. The novel MFC adsorbent was proven to have higher efficiency, better economy, and environmental sustainability, and be more environmentally friendly.

Проведены исследования качества 12 образцов питьевой бутилированной воды в условиях аккредитованной испытательной лаборатории. Исследование информативности маркировки образцов воды выявило, что не все производители выполняют требования ТР ТС 022/2011. Дана оценка органолептических, физико-химических и микробиологических показателей питьевой воды. Определены критерии безвредности химического состава образцов. Исследован макро- и микроэлементный состав. Выявлена необходимость повышения степени ответственности производителей при формировании качества. The quality of 12 samples of bottled drinking water was studied in an accredited testing laboratory. The study of informative labeling of water samples revealed that not all manufacturers fulfill the requirements of TR TS 022/2011. The evaluation of organoleptic, physicochemical and microbiological indicators of drinking water is given. Criteria of harmlessness of the chemical composition of samples are defined. It is investigated macro- and microelement composition of drinking water. The necessity to increase the degree of responsibility of producers in the formation of quality is revealed.

Abstract. The stable isotopic compositions of nitrate dissolved in 49 types of bottled drinking water collected worldwide were determined, to trace the fate of atmospheric nitrate (NO3–atm) that had been deposited into subaerial ecosystems, using the 17O anomalies (Δ17O) of nitrate as tracers. The use of bottled water enables collection of groundwater recharged at natural, background watersheds. The nitrate in groundwater had small Δ17O values ranging from −0.2‰ to +4.5‰ (n = 49). The average Δ17O value and average mixing ratio of atmospheric nitrate to total nitrate in the groundwater samples were estimated to be 0.8‰ and 3.1%, respectively. These findings indicated that the majority of atmospheric nitrate had undergone biological processing before being exported from the surface ecosystem to the groundwater. Moreover, the concentrations of atmospheric nitrate were estimated to range from less than 0.1 μmol l−1 to 8.5 μmol l−1, with higher NO3–atm concentrations being obtained for those recharged in rocky, arid or elevated areas with little vegetation and lower NO3–atm concentrations being obtained for those recharged in forested areas with high levels of vegetation. Additionally, many of the NO3–atm-depleted samples were characterized by elevated δ15N values of more than +10‰. Uptake by plants and/or microbes in forested soils subsequent to deposition and the progress of denitrification within groundwater likely plays a significant role in the removal of NO3–atm.
