Deaths from bronchitis and pneumonia increased more than sevenfold. The death rate in London’s East End increased ninefold. Initial reports estimated that about 4,000 died prematurely in the immediate aftermath of the smog.
What caused London smog in 1952 and how did it affect human health?
The smog developed primarily because of extensive burning of high-sulfur coal. The health effects were both immediate and long lasting, with a recent study revealing an increased likelihood of childhood asthma development in those exposed to the Great Smog while in utero or during their first year of life.
What were the effects of London smog?
During its duration, there was an increase in hospitalizations relating to bronchitis and pneumonia, and even cattle from Smithfield, a district in central London, reportedly choked to death. The effects of the smog were long-lasting, however, and present-day experts now put the total death toll at 12,000.
How did the London fog affect the respiratory system?
They found that there was a 19.8% increase in the chance of having childhood asthma among those exposed to the smog in the first year of their life. This group also had a slightly higher chance of developing adult asthma later in life.
How did the Great Smog of 1952 affect the environment?
A fog so thick and polluted it left thousands dead wreaked havoc on London in 1952. The smoke-like pollution was so toxic it was even reported to have choked cows to death in the fields. It was so thick it brought road, air and rail transport to a virtual standstill.
What impact does smog have on people’s health?
Ground-level ozone (a key component of smog) is associated with many health problems, such as diminished lung function, increased hospital admissions and emergency room visits for asthma, and increases in premature deaths.
How does living with smog affect people’s health?
When inhaled, smog irritates our airways, increasing our risk of serious heart and lung diseases. These health risks are why many cities monitor smog levels. On a high ozone-alert day, for example, your eyes and throat may burn, and you may cough and wheeze.
What are four effects of smog?
Types of effects smog has include: Eye, nose and throat irritation. Decreased lung function. Aggravation of respiratory or heart disease.
Who was most affected by the Great Smog?
Most of the victims were very young or elderly, or had pre-existing respiratory problems. In February 1953, Marcus Lipton suggested in the House of Commons that the fog had caused 6,000 deaths and that 25,000 more people had claimed sickness benefits in London during that period.
What is a negative effect of smog that affects the people of London England?
London’s Great Smog of 1952 resulted in thousands of premature deaths and even more people becoming ill. The five December days the smog lasted may have also resulted in thousands more cases of childhood and adult asthma.
Does fog affect oxygen levels?
The fog and haze can increase the air humidity and decrease the oxygen level.
Does fog make it harder to breathe?
“People who have a sensitivity to air pollution or have lung problems or heart problems will find breathing more difficult when the air is saturated with moisture,” Meade said. Fog and pollution combined make for an “awful time breathing,” she said.
What were some of the harmful effects of the polluted fog in Donora?
The 1948 Donora smog killed 20 people and caused respiratory problems for 6,000 of the 14,000 people living in Donora, Pennsylvania, a mill town on the Monongahela River 24 miles (39 km) southeast of Pittsburgh. The event is commemorated by the Donora Smog Museum.
How many people died smog 1952?

When did smog first become a problem for humans?
The first recognized episodes of ‘smog’ occurred in Los Angeles in the summer of 1943. Visibility was only three blocks. People suffered from burning eyes and lungs, and nausea. The phenomenon was termed a “gas attack” and blamed on a nearby butadiene plant.
What happened after the Great London smog?
Slow to act at first, the British government ultimately passed the Clean Air Act four years later, in 1956, as a direct response to the lethal fog. The act established smoke-free areas throughout the city and restricted the burning of coal in domestic fires as well as in industrial furnaces.
What types of health problems are caused when smog is high?
It can also cause other health problems including:
- Aggravated respiratory disease such as emphysema, bronchitis and asthma.
- Lung damage, even after symptoms such as coughing or a sore throat disappear.
- Wheezing, chest pain, dry throat, headache or nausea.
- Reduced resistance to infections.
- Increased fatigue.
Which organ is affected by smog?
The impact of air pollution on the respiratory tract – the nose, throat and lungs– is the most widely studied. It causes everything from breathlessness and asthma, to chronic laryngitis and lung cancer.
What are the health effects of smog on people on plants and trees?
It may reduce photosynthesis, increase precipitation, and reduce temperatures. Ozone may damage native plants and some crop plants. Ozone may slow plant growth or damage leaves. Pollutants emitted into the air cause lung and other diseases in humans.
What kind of diseases can be caused due to smog?
There is no doubt that exposure to smog or haze can cause respiratory diseases (COPD, asthma, lung cancer, and lower respiratory infections), cerebrovascular diseases, ischemic heart diseases, and other medical conditions.
Can smog damage your skin?
Irregular skin pigmentation, dullish greyish shades will start appearing. A more serious impact could be inflammation via oxidative damage, that leads to DNA mutations atopic dermatitis, psoriasis and even skin cancer. Smog pollutants stick to the skin and deplete the body of its vitamins.
