According to a research, having plants all over your house can lower your chance of getting cancer.

Researchers in Sydney, Australia, discovered that hazardous gases, including carcinogenic contaminants, may be eliminated from indoor air by houseplants.

Researchers at the University of Technology Sydney (UTS) examined plants’ capacity to remove gasoline fumes, one of the primary carcinogens present in buildings all over the world, in a groundbreaking study.

In just eight hours, the plants in the study were able to successfully remove 97 percent of the most dangerous toxins from the air.

The World Health Organization (WHO) estimates that home air pollution contributed to 3.2 million of the world’s premature deaths in 2020.

Inhaling gasoline fumes can lead to lung irritation, headaches and nausea, and long-term exposure has been linked to an increased risk of cancer, asthma and other chronic diseases, contributing to a shorter life expectancy.

While not proven, this suggests that removing these chemicals from indoor air could in turn reduce cancer risk.

The UTS researchers, who teamed up with Australian plant-scaping company Ambius for the study, claim that most people spend 90 percent of their time indoors, at home, at work or at school, so improving air quality is ‘ crucial’.

Many workplaces, homes and even some schools have garages, are on a busy road or have a gas station nearby, exposing people to gasoline-related chemicals on a daily basis, the researchers said.

For the studyAmbius created nine green walls – vertical structures to which different types of plants or other greenery are attached.

The researchers then exposed each green wall — which had four plants attached to it and sealed in Perspex chambers — to petroleum vapor.

To do this, they placed a 0.25 ml cocktail of gasoline-related chemicals in 80-degree heated baths, which were then placed in the nine perspex chambers. The scientists then waited for the fumes to turn to vapor.

Each room was tested every hour to measure how much toxic fumes had been lifted from the air by the houseplants.

It turned out that most of the fumes were removed within an eight-hour period, but the chemical levels continued to decline after this time.

Of the many gasoline-related chemicals tested, the study found that plants were best at removing pneumonia-causing compounds called alkanes — 97.9 percent of which disappeared.

Benzene, a known carcinogen, also had one of the highest removal rates (85.9 percent).

Associate professor Fraser Torpy, who led the study, said the study is the first time plants have been tested for their ability to remove gasoline-related compounds and the results are “amazing.”

“Not only can plants remove most pollutants from the air within hours, they also remove the most harmful gasoline-related pollutants from the air in the most efficient way,” he added.

Johan Hodgson, managing director of Ambius, said the research has provided new evidence for the crucial role houseplants and green walls play in cleaning the air we breathe quickly and sustainably.

He said: ‘We know that indoor air quality is often significantly more polluted than the outdoor air, which in turn affects mental and physical health.

“But the good news is that this research has shown that something as simple as planting indoors can make a huge difference.”

Mr Hodgson said the results confirmed the positive feedback his company had received after installing factories in hundreds of offices across Australia.

The type of plants used for the study were Devil’s Ivy (Scindapsus Aureus), Spider Plant (Chlorophytum), and Arrowhead Plant (Syngonium).
