Alternative new technologies are urgently needed to overcome the rapidly increasing global water scarcity. Atmospheric dew water is a potential source of potable water, as the earth’s atmosphere contains billions of tons of fresh water (98% in a vapor state). The atmospheric water generator (AWG) converts water vapor into liquid water and is a promising solution for water scarcity. We provide the first comprehensive analysis of the chemical profiles of water produced for several months by an AWG in the city of Tel Aviv, Israel. Metals, inorganic ions, volatile organic compounds (VOCs), and semi-VOCs were analyzed in the dew water. The main elements found were ammonium, calcium, sulfate, and nitrate. Location of the sampling site in an urban residential area, between major traffic routes, likely affected the chemical composition of the produced dew water. Nevertheless, the produced water nearly always (day and night in different seasons) met the WHO and Israeli drinking water standards. Thus, even in a highly developed urban environment, the AWG offers an excellent alternative source of safe drinking water throughout the year.

在城市环境中使用大气水发生器 (AWG) 生产安全饮用水

迫切需要替代新技术来克服迅速加剧的全球水资源短缺。大气露水是饮用水的潜在来源，因为地球大气层含有数十亿吨淡水（98% 处于蒸气状态）。大气水生成器 (AWG) 将水蒸气转化为液态水，是解决缺水问题的有前途的解决方案。我们对以色列特拉维夫市的 AWG 几个月来生产的水的化学成分进行了首次综合分析。分析了露水中的金属、无机离子、挥发性有机化合物 (VOC) 和半 VOC。发现的主要元素是铵、钙、硫酸盐和硝酸盐。采样点位于城市居民区，主要交通路线之间，可能影响了产生的露水的化学成分。尽管如此，产出的水几乎总是（不同季节的白天和黑夜）符合世界卫生组织和以色列的饮用水标准。因此，即使在高度发达的城市环境中，AWG 也能全年提供出色的安全饮用水替代来源。
