For over sixty years, the soil in certain parts of the Swiss city of Lausanne, the country’s fourth largest city, have been intoxicated with dangerous chemicals, raising certain dire implications for many of its children.

Lausanne is known to be the capital of Olympics and sport in the country, serving as a host city for plenty of sporting events and competitions. The recently-discovered chemical pollution has come as a rather big shock to the city, having been found to be caused by an old waste incinerator that operated from 1958 to 1982.

“There are some who’ve grown vegetables in their garden for years and then we tell them 'no marrows, no cucumbers'. It obviously raises questions for them,” said a city resident and vegetable garden owner, Didier Burgi.

It’s been estimated that an area of around 20 square kilometers around the site of the old waste incinerator has been contaminated by pollutants, and a warning has been issued to all parents to keep their children from ingesting any soils. As well as this, it’s also been stated that certain homegrown vegetables in the area should no longer be eaten due to contamination fears.

The pollution had remained unnoticed for over 60 years because at no point had anybody decided to test the soils for dioxins – a group of chemically-related compounds that are known to act as environmental pollutants.

According to the World Health Organisation, dioxins are toxic, having been known to cause cancer, damage the immune system, and can even cause reproductive and developmental issues with long-term exposure.

Residents and authorities are left concerned over how many people may have been affected by the intoxication over the many years. Now that it has been noticed, evasive actions can be taken, but many are left wondering what kind of damage has already been done.

“We realise it is indeed a big problem today in Lausanne,” said a member of the Lausanne city council, Natacha Litzistorf. “But it raises the question about all other cities that had incineration plants at that time." 

 

The intoxication of the soils was only discovered earlier this year between January and May, by complete accident during a separate ecological survey. Typically, monitoring for pollution had been focused on air and water, with few considering the possibilities of polluted soil.

Soil analyses had been triggered in 126 sites across the city since the discovery, with experts trying to determine where and how the intoxication has spread. What they found was that both the levels of those dioxins, alongside the size of the affected area were much worse than they could have anticipated.

“As we did not look for dioxins, we never found them,” said Litzistorf. “We quickly suspected the cause was linked to a former incinerator.”

The old waste incinerator blamed for the pollution, called the Vallon plant, was opened in 1958 and hasn’t been open since 2005. Luckily, the damage stopped in 1982 when the plant’s filters had received sufficient environmental upgrades.

Litzistorf added that: “At the time, it was thought much better to site waste incinerators in the city centre to protect agriculture in the countryside.”
