Your Walls are Covered in Sweat

Lactic acid—the main chemical in human sweat—leaves our skin, travels through the air, and sticks to our walls. And according to a team of chemists who outfitted the University of Colorado Art Museum with state-of-the-art air-sampling instruments: it’s doing so at surprisingly high rates. The finding highlights the need to better understand the fate of the indoor chemicals, especially those that may impact human health.

Art enthusiasts leave chemical traces of gallery visits on artwork

The priceless, porous artwork that adorns the walls of a US university art gallery probably hosts a surprising proportion of the chemicals that have been breathed and sweated out by its visitors, a month-long field study has found. University of Colorado Boulder chemists spent four weeks monitoring the air inside a gallery at their university’s new art museum, looking at levels of volatile and semi-volatile organic compounds, carbon dioxide and other trace gases known to be given off by humans. The proportions emitted by a typical person has been determined by previous studies, here the team wanted to catalogue where these chemicals go – their fate.

Is Sunday dinner bad for you?

Everyone is aware of air pollution in cities. The mix of traffic fumes, cigarette smoke and smog from factories harms our environment and can cause respiratory disease. But little research has been done about air quality where we spend around 90% of our time: indoors. Could cooking a roast dinner at home be as bad for our health as rush-hour exhaust? The HOMEChem project decided to find out.

The Hidden Air Pollution in Our Homes

Food magazines typically celebrate Thanksgiving in mid-July, bronzing turkeys and crimping piecrust four months in advance. By that time last year, Marina Vance, an environmental engineer at the University of Colorado Boulder, had already prepared two full Thanksgiving dinners for more than a dozen people. Vance studies air quality, and, last June, she was one of two scientists in charge of homechem, a four-week orgy of cooking, cleaning, and emissions measurement, which brought sixty scientists and four and a half million dollars’ worth of high-tech instrumentation to a ranch house on the engineering campus of the University of Texas at Austin.

Tostar pan puede exponer a la gente a más polución que la intersección de dos avenidas

La operación de este electrodoméstico expone a más polución que el centro de Nueva York. Un nuevo estudio de la Universidad de Colorado (CU) en Boulder advirtió que las tostadoras son un factor importante de la polución del aire. Apenas se las enciende, comienzan a liberar partículas tóxicas en una cantidad mayor a la que, por ejemplo, afecta a una persona que está en la intersección […]

Cooking, boiling water can lead to high level of indoor air pollution, says study

Moreover, the airborne chemicals that originate inside a house do not stay there. The volatile organic compounds (VOCs) from products such as shampoo, perfume and cleaning solutions eventually escape outside and contribute to ozone and fine particle formation, making up an even greater source of global atmospheric air pollution than cars and trucks do, the researchers explained in the paper presented at the 2019 AAAS Annual Meeting in Washington.

How to pollution-proof your roast dinner

This week we learned that preparing a traditional roast dinner with the kitchen windows shut – something most of us do in winter – causes the pollution levels inside our homes to become worse than central London on a congested day.

Cooking, Cleaning Could Raise Air Pollution Levels In Homes, Study Says

Researchers at the University of Colorado say cooking, cleaning, and other household activities generate levels of pollution in the average home similar to that of a polluted major city. Shampoos, perfumes, and cleaning products produce airborne chemicals in our houses but at higher concentrations than previously thought.

Bringing Attention To Indoor Air Pollution

Even tasks as simple as boiling water over a stovetop flame could contribute to potentially dangerous levels of gaseous air pollutants and suspended particles. “Even the simple act of making toast raised particle levels far higher than expected,” Vance said.
