The 1962 London smog was a severe smog episode that affected London, England, in December 1962. It occurred ten years after the Great Smog of London, in which serious air pollution had killed as many as 12,000 people. While the 1952 smog had led to the passing of the 1956 Clean Air Act, which restricted the burning of domestic fuels in urban areas with the introduction of smokeless zones, fogs continued to be smoky in London for some years after the act as residents and operators were given time to convert from domestic fuels. The December 1962 smog is thought to have led to the deaths of up to 700 people.

Background

Serious smog events had become a common occurrence in London since the second half of the 19th century, with industrialisation causing an increase in air pollution that often killed hundreds of the city's inhabitants when it amassed in great quantities during the winter months. [1] Since the Second World War, severe smog episodes had occurred in November 1948 (causing an estimated 700 to 800 deaths), December 1952 (12,000 deaths), January 1956 (1,000 deaths), December 1957 (750 deaths) and January 1959 (over 200 deaths). [2] The 1952 Great Smog of London had forced the government to consider new anti-pollution legislation, which eventually led to the passage of the 1956 Clean Air Act that restricted the burning of domestic fuels in urban areas with the introduction of "smokeless zones". [3] [2] Despite the passing of the act, residents and operators were given time to convert from the burning of domestic fuels, and so smoky fogs continued to be a problem for some time, as they were in 1956, 1957 and 1959. [3] [2]

Event

The thick, smoky fog enveloped London between 4 and 7 December 1962. [3] [4] Visibility was reduced to a level that lighted objects could only be seen as far as 50 feet away, while the smog caused the cancellation of flights at Heathrow Airport as well as the closure of the airport itself. [4] Railway services became severely limited as train drivers could not see signals. A strong smell of sulphur and coal smoke became overwhelming, and pedestrians largely wore scarfs, surgical masks, handkerchiefs, or other makeshift filtering devices across their faces. [4] The smoke levels of the smog were about one third of those in 1952, but levels of sulphur dioxide were about the same. [4]

The Ministry of Health provided warnings to those individuals at most risk, such as sufferers of chest and heart complaints, and instructed them to "stay indoors and rest as much as possible". [3] Doctors were encouraged to prescribe masks for vulnerable patients or "do-it-yourself masks", such as thick cotton gauze or a scarf around the mouth and nose. [3] The public were also told to only use coke or other smokeless fuel, not burn rubbish or light bonfires and to keep windows closed. [3]

Driving conditions became extremely hazardous in the smog, with visibility reduced in some places to zero. [3] The level of smoke in London's atmosphere during the event was two and a half times higher than for an average winter day of that time, and the level of sulphur dioxide was seven times higher. [3]

Health effects

The smog had the effect of causing a continual metallic taste in the mouth and irritation of the nose and eyes. [4] Cases of bronchitis increased significantly during the smog episode, including in children. [4] It was estimated that in the City of London alone, the air pollution led to 133 excess deaths, with Greater London as a whole seeing an estimated 300–700 deaths in total. [4] [2]

Aftermath

In total, the smog caused an estimated 20 million pounds in damages, including in health costs. [4] The event highlighted some of the weaknesses of the 1956 Clean Air Act, in that the act had dealt with smoke emissions but had not reduced the discharge of sulphur dioxide, and this caused increasing criticism. [4] [3] The act was revised in 1968 when industries burning coal, gas or other fuels were ordered to use tall chimneys. In 1974 the first Control of Air Pollution act also introduced regulations on the composition of motor fuels. [3] Smoke Control Areas (SCA) have led to a gradual reduction in smoke pollution emitted from domestic and industrial premises in modern times. Only permitted DEFRA-UK-AIR fuels may be used in chimneys using approved appliances. Failure to adhere to the legislation leaves the user exposed to fines and other sanctions. [5]

<span class="mw-page-title-main">Smog</span> Smoke-like, fog-like air pollutions

Smog, or smoke fog, is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a portmanteau of the words smoke and fog to refer to smoky fog due to its opacity, and odor. The word was then intended to refer to what was sometimes known as pea soup fog, a familiar and serious problem in London from the 19th century to the mid-20th century, where it was commonly known as a London particular or London fog. This kind of visible air pollution is composed of nitrogen oxides, sulfur oxide, ozone, smoke and other particulates. Man-made smog is derived from coal combustion emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions.

<span class="mw-page-title-main">Smoke</span> Mass of airborne particulates and gases

Smoke is a suspension of airborne particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires, but may also be used for pest control (fumigation), communication, defensive and offensive capabilities in the military, cooking, or smoking. It is used in rituals where incense, sage, or resin is burned to produce a smell for spiritual or magical purposes. It can also be a flavoring agent and preservative.

The Great Smog of London, or Great Smog of 1952, was a severe air pollution event that affected London, England, in December 1952. A period of unusually cold weather, combined with an anticyclone and windless conditions, collected airborne pollutants—mostly arising from the use of coal—to form a thick layer of smog over the city. It lasted from Friday 5 December to Tuesday 9 December 1952, then dispersed quickly when the weather changed.

<span class="mw-page-title-main">Haze</span> Dry particulates obscuring clarity of the sky

Haze is traditionally an atmospheric phenomenon in which dust, smoke, and other dry particulates suspended in air obscure visibility and the clarity of the sky. The World Meteorological Organization manual of codes includes a classification of particulates causing horizontal obscuration into categories of fog, ice fog, steam fog, mist, haze, smoke, volcanic ash, dust, sand, and snow. Sources for particles that cause haze include farming, traffic, industry, windy weather, volcanic activity and wildfires. Seen from afar and depending on the direction of view with respect to the Sun, haze may appear brownish or bluish, while mist tends to be bluish grey instead. Whereas haze often is considered a phenomenon occurring in dry air, mist formation is a phenomenon in saturated, humid air. However, haze particles may act as condensation nuclei that leads to the subsequent vapor condensation and formation of mist droplets; such forms of haze are known as "wet haze".

<span class="mw-page-title-main">Air pollution</span> Presence of dangerous substances in the atmosphere

Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. It is also the contamination of the indoor or outdoor environment either by chemical, physical, or biological agents that alters the natural features of the atmosphere. There are many different types of air pollutants, such as gases, particulates and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and crops, and may damage the natural environment or built environment. Air pollution can be caused by both human activities and natural phenomena.

<span class="mw-page-title-main">Pea soup fog</span> Type of smog

Pea soup fog is a very thick and often yellowish, greenish or blackish fog caused by air pollution that contains soot particulates and the poisonous gas sulphur dioxide. This very thick smog occurs in cities and is derived from the smoke given off by the burning of soft coal for home heating and in industrial processes. Smog of this intensity is often lethal to vulnerable people such as the elderly, the very young (infants) and those with respiratory problems. The result of these phenomena was commonly known as a London particular or London fog; in a reversal of the idiom, "London particular" became the name for a thick pea and ham soup.

A multi-fuel stove is similar to a wood-burning stove in appearance and design. Multifuel refers to the capability of the stove to burn wood and also coal, wood pellets, or peat. Stoves that have a grate for the fire to burn on and a removable ash pan are generally considered multi-fuel stoves. If the fire simply burns on a bed of ash, it is a wood-only fuelled appliance, and cannot be used for coal or peat.

Air Pollution in Mexico City has been of concern to the city's population and health officials for decades. In the 20th century, Mexico City's population rapidly increased as industrialization brought thousands of migrants from all over the world. Such a rapid and unexpected growth led to the UN declaring Mexico City as the most polluted city in the world in 1992. This was partly due to Mexico City's high altitude, which causes its oxygen levels to be 25% lower. Carbon-based fuels also do not combust completely. Other factors include the proliferation of vehicles, rapid industrial growth, and the population boom. The Mexican government has several active plans to reduce emission levels which require citizen participation, vehicular restrictions, increase of green areas, and expanded bicycle accessibility.

Air pollution in the United Kingdom has long been considered a significant health issue, and it causes numerous other environmental problems such as damage to buildings, forests, and crops. Many areas, including major cities like London, are found to be significantly and regularly above legal and recommended pollution levels. Air pollution in the UK is a major cause of diseases such as asthma, lung disease, stroke, cancer, and heart disease, and is estimated to cause forty thousand premature deaths each year, which is about 8.3% of deaths, while costing around £40 billion each year.

<span class="mw-page-title-main">Air pollution in India</span>

Air pollution in India is a serious environmental issue. Of the 30 most polluted cities in the world, 21 were in India in 2019. As per a study based on 2016 data, at least 140 million people in India breathe air that is 10 times or more over the WHO safe limit and 13 of the world's 20 cities with the highest annual levels of air pollution are in India. 51% of the pollution is caused by industrial pollution, 27% by vehicles, 17% by crop burning and 5% by other sources. Air pollution contributes to the premature deaths of 2 million Indians every year. Emissions come from vehicles and industry, whereas in rural areas, much of the pollution stems from biomass burning for cooking and keeping warm. In autumn and spring months, large scale crop residue burning in agriculture fields – a cheaper alternative to mechanical tilling – is a major source of smoke, smog and particulate pollution. India has a low per capita emissions of greenhouse gases but the country as a whole is the third largest greenhouse gas producer after China and the United States. A 2013 study on non-smokers has found that Indians have 30% weaker lung function than Europeans.

The 2013 Eastern China smog was a severe air pollution episode that affected East China, including all or parts of the municipalities of Shanghai and Tianjin, and the provinces of Hebei, Shandong, Jiangsu, Anhui, Henan, and Zhejiang, during December 2013. A lack of cold air flow, combined with slow-moving air masses carrying industrial emissions, collected airborne pollutants to form a thick layer of smog over the region. Levels of PM2.5 particulate matter averaged over 150 micrograms per cubic metre; in some areas, they were 300 to 500 micrograms per cubic metre.

Air pollution measurement is the process of collecting and measuring the components of air pollution, notably gases and particulates. The earliest devices used to measure pollution include rain gauges, Ringelmann charts for measuring smoke, and simple soot and dust collectors known as deposit gauges. Modern air pollution measurement is largely automated and carried out using many different devices and techniques. These range from simple absorbent test tubes known as diffusion tubes through to highly sophisticated chemical and physical sensors that give almost real-time pollution measurements, which are used to generate air quality indexes.
