The study, which was carried out for Transport for London by Kings College London’s Environmental Research Group, attributes these premature deaths to two main pollutants: fine particulates known as PM2. 5 and the toxic gas nitrogen dioxide (NO2).
What is the main pollutant in London smog?
According to the UK’s Met Office, the following pollutants were emitted each day during the smoggy period: 1,000 tonnes of smoke particles, 140 tonnes of hydrochloric acid, 14 tonnes of fluorine compounds and 370 tonnes of sulphur dioxide which may have been converted to 800 tonnes of sulphuric acid.
What was the cause of the London smog disasters?
Great Smog of London, lethal smog that covered the city of London for five days (December 5–9) in 1952, caused by a combination of industrial pollution and high-pressure weather conditions. This combination of smoke and fog brought the city to a near standstill and resulted in thousands of deaths.
What chemicals were in the London smog?
Burning coal releases sulfur dioxide and nitrogen dioxide, which interacted in the water droplets common in the London skies. Initially, the water particles in the fog were large enough to dilute the acid, forming a near neutral fog.
What fuel was most responsible for producing the Great Smog of London in December 1952?
How the smog of 1952 formed. The weather in November and early December 1952 had been very cold, with heavy snowfalls across the region. To keep warm, the people of London were burning large quantities of coal in their homes. Smoke was pouring from the chimneys of their houses.
What is the biggest polluter in London?
Most pollution in London is caused by road transport and domestic and commercial heating systems. The UK Air Quality Standards Regulations 2010 sets standards for a number of pollutants than can harm human health and the environment. These are based on EU limit values and include: sulphur dioxide (SO2)
What is the co2 emissions for London?
In 2019, London’s CO2e emissions were 31.4 million tonnes, down from 32.8 in 2018. This is a 31 per cent reduction on 1990 levels and a 39 per cent reduction since peak emissions in 2000.
How is smog formed in London?
A period of cold weather, combined with an anticyclone and windless conditions, collected airborne pollutants mostly from the use of coal to form a thick layer of smog over the city. It lasted from Friday 5 to Tuesday 9 December 1952 and then dispersed quickly after a change of weather.
What is the main cause of pollution in the UK?
Domestic burning is the UK’s largest source of particulate matter air pollution.
Why is London smog called reducing smog?
This smog is formed by the mixture of smoke, fog, and sulfur dioxide. This smog also acts as a reducing agent in atmospheric pollution. Therefore, it is also known as reducing smog.
Why is it called London fog?
As the warm milk hit the black Earl Grey tea it created a cloudy plume, turning the colour of the fog-laden London afternoon and thus the name was born.
How did the Great Smog of London end?
After five days of living in a sulfurous hell, the Great Smog finally lifted on December 9, when a brisk wind from the west swept the toxic cloud away from London and out to the North Sea.
When was the last smog in London?
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.

What fuel source was behind the Great Smog in London in 1952 what fuel is now used in its place?
What fuel source was behind the Great Smog in London in 1952? What fuel is now used in its place? A softer, more polluting form of coal. Methane gas (natural gas) is now used in its place in many developed countries.
What types of pollution does London have?
The main pollutants of concern in London are fine particulate matter (PM2. 5) and nitrogen dioxide (NO2), which are generated in London from urban transport and heating of homes, among other sources.
Why does London have a pollution problem?
London suffers from traffic related pollution in a similar way to most UK cities, but the sheer size of the city, along with a dense road network and high buildings, means that central London tends to be one of the most polluted places in the UK.
How is London’s air pollution?
5 level of 11.4µg/m3. While this correlates to a London AQI indicator of “1, Low” on the UK’s Daily London Air Quality Index, this is still is 14% above the WHO recommendation.
What is the biggest CO2 emitter in UK?
In 2020, 24% of net greenhouse gas emissions in the UK were estimated to be from the transport sector, 21% from energy supply, 18% from business, 16% from the residential sector and 11% from agriculture.
What is the biggest producer of CO2 in UK?
RWE produced 12.7 million metric tons of carbon dioxide (MtCO2) that year, which was twice the amount produced by the UK’s second-largest carbon polluter – Tata Steel.

What is the biggest contributor to carbon emissions UK?
Burning fossil fuels to make electricity is the biggest source of carbon emissions in the UK, which makes it vital that we phase out fossil fuels as quickly as possible, moving towards a 100% renewable future by 2050.
Is London smog a secondary pollutant?
Examples of a secondary pollutant include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides (NOx) combine in the presence of sunlight; NO2, which is formed as NO combines with oxygen in the air; and acid rain, which is formed when sulfur dioxide or nitrogen oxides react with water.
