IF YOU’RE HIKING in Los Angeles, your naked eye can’t really tell the difference between pollution and run-of-the-mill fog. Nor can you measure the levels of particulate matter or nitrogen oxide without special equipment.

　　如果你在洛杉矶徒步旅行，单凭肉眼根本不能区分空气污染和稀疏寻常的雾气。没有特殊的仪器，你既不能测量颗粒物分子的程度，也无法感知一氧化氮的浓度。

　　斯蒂芬妮·波萨维奇和米里亚姆·奎克是伦敦的两位数据艺术家。他们设计出了一套项链和眼镜，使波动的空气污染级数能被感知。这套珠状饰品并不过于政治化，不像“力挺伯尼·桑德斯”(竞选2016年美国总统的一位联邦参议院，政治观点属极左派，以言论直白犀利闻名)的胸针，波萨维奇和奎克设计的Air Transformed通过使人感受到身体上的不适，激发人采取行动。波萨维奇称：“我们想要让人肉体上感受到污染物的负荷。“
