Dozens of analytical instruments have spent a month observing the chemistry of the air inside a three bed house
The largest-ever field study to observe how chemicals behave in indoor air has drawn to a close in the US. $4.5 million (£3.4 million) of analytical chemistry instruments, together with scientists from 20 different research groups, travelled to Texas to spend June crammed inside a small home, and four nearby shipping containers, collecting data about the chemistry of the air inside the house.
