Deadly air in our cities: the invisible killer | Environment

In the winter you can taste and smell the pollution,” says Kylie ap Garth, drinking coffee in a cafe in Hackney, east London. “My eldest is eight and he has asthma. Being outside, he would have a tight chest and cough. I just assumed it was the cold weather. I didn’t realise there was a link to the cars.”She is not exaggerating. The main road from Bethnal Green tube station is clogged with traffic, the smell of diesel fumes mixing with smoke from barbecue grill restaurants and construction dust. Anyone trying to escape from the roadside to the canal towpath finds only that the fumes are swapped with coal smoke from the canal boats.“I hadn’t made the connection before either,” says Shazia Ali. “I’m from Birmingham and have lived near main roads all my life. It was leaded petrol that was supposed to be the major thing. I can’t remember people talking about diesel fumes. Then, in 2015, I became pregnant with my third child … my husband and oldest child were diagnosed with asthma, and I read about the Exhale study. Suddenly air pollution came onto my family’s radar.”The Exhale (Exploration of Health and Lungs in the Environment) study tested the lung volume of eight and nine-year-old children in more than 25 schools in east London, and the findings were shocking. As a result of the high levels of traffic pollution, the children’s lung capacity had been stunted. Dr Ian Mudway, a respiratory toxicologist at King’s College London, said at the time: “The data show that traffic pollution stops children’s lungs growing properly … by eight-to-nine-years-old, children from the most polluted areas have 5-10% less lung capacity and they may never get that back.”In fact, that research was merely the latest in a long line of studies around the world that had reached the same conclusion: children living near busy roads grew up with stunted lungs. The Californian Children’s Health Study, ongoing since 1993, measures the lung function of thousands of schoolchildren over five-to-seven-year periods. Living within a third of a mile from a motorway was associated with a 2% reduction in lung capacity. In particular, exposure to NO₂ (nitrogen dioxide, a gas that comes from vehicle fumes and boilers) and PM2.5 (tiny particles suspended in the air) damages our lungs and can even enter our bloodstream.The effects can be devastating, and we are only just beginning to discover their true extent. Last week scientists put the number of early deaths caused worldwide by air pollution at double previous estimates: 8.8 million a year, according to research published in the European Heart Journal, meaning toxic air is killing more people than tobacco smoking.FacebookTwitterPinterest Children wear protective masks during a polluted day in Beijing, China. Photograph: Roman Pilipey/EPA In 2014, like Kylie and Shazia, I didn’t know much about air pollution. I had just become a father when, living in London at the time, an Evening Standard headline caught my eye: Oxford Street had the worst diesel pollution in the world. This came as a surprise: the shopping street where I took my daughter to pick out her first pram had some of the most polluted air on Earth.Where were the health warnings, the public information signs, the protesters marching? All I could see were happy, oblivious shoppers. Weeks later came another headline: “Oxford Street pollution levels breached EU annual limit just four days into 2015.”We had sleepwalked into a public health crisis. And not just in the UK, but across the world. The 2015 smog in Beijing was so bad that it was dubbed the “Airpocalypse”. Pictures circulated on social media of Beijing students sitting their exams so couched in smog that they could barely see the neighbouring table. The toxic smog that covers Delhi every Diwali now lasts for months at a time.Eventually, in the summer of 2016, my young family and I left London and moved to semi-rural Oxfordshire. I felt the relief of escape. I could breathe easy. The first time my daughter went out into our new garden at night, she asked what all the lights in the sky were. Twinkle Twinkle Little Star was no longer an abstract concept. But I also felt a sense of defeat. Had I taken the easy way out? Shouldn’t I have stayed and fought for change?Parents who did just that include Jemima Hartshorn and Phoebe Quayle. In April 2017 Hartshorn founded a group called Mums for Lungs while she was on maternity leave and living in Brixton. She formed a core group of 10 volunteers, including Quayle, plus a legion of footsoldiers handing out flyers across London.Mums for Lungs campaigned for the Ultra Low Emission Zone (the ULEZ, which will begin on 8 April), to replace diesel buses with hybrid or EV, to improve walking and cycling infrastructure, and spread awareness – not just about traffic but household log burners, too.FacebookTwitterPinterest Traffic in Madrid, where the city council has recently banned all but zero-emissions vehicles from central areas.

They have a stove that they rarely use, so they lit it for an experiment … the monitor went mental, and it wasn’t even in the same room … But people get defensive, like ‘how dare you say I can’t have a wood-burning stove?’”She feels that the enforcement of existing clean air laws is sorely lacking. “It’s kind of outrageous that it takes a small group of campaigning mums to be left to tell residents about this … We need a massive public health campaign.”In Hackney, ap Garth and Ali have also been taking matters into their own hands. Ali runs a volunteer organisation called I Like Clean Air, while ap Garth campaigns for safer streets around the schools in her area. Last summer, as a result of her work, her son’s primary school became one of five to pilot...
