Water fog composition was investigated at a fog harvesting installation in the coast of Atacama (North Chile). Chañaral is historically affected by mining contamination discharges. Hydro-chemical characterization of fog water from top of the mountain (where capture installation is located) and at the bottom of the mountain (after vertical transportation where an aquaponic system is located) revealed many compositional differences that compromise the use of water. High acidity and high concentrations in Cu and As in water collected on top of the mountain were found; meanwhile, acidity and Cu decreased, and As levels overpassed the drinking water standards after the vertical transportation. Collected data was assessed according to national and international regulatory standards, neutralization factors (NF), sodium adsorption ratio (SAR), and ion ratios to determine origin of contamination and suitability of destined for human consumption, irrigation, or aquaculture purposes.
在智利北部阿塔卡马海岸的一个雾水采集装置中，对水雾气组成进行了研究。恰纳拉历史上受到矿业污染排放的影响。对山顶（雾水采集装置所在地）和山底（经过垂直运输到达一个水培系统所在地）采集的雾水进行水化学特征分析，结果显示许多成分差异，影响水的使用。在山顶采集的水样中发现酸度高，铜和砷浓度高；而在经过垂直运输后，酸度和铜的浓度降低，砷的含量超过了饮用水标准。收集到的数据根据国家和国际监管标准、中和因子（NF）、钠吸附比（SAR）和离子比进行评估，以确定污染的来源以及用于人类消费、灌溉或水产养殖的适宜性。
