London’s air pollution levels have been increasing in the last few years due to an increase in road traffic and the number of petrol cars.Polluting vehicles are the biggest contributor to air pollutants in Central London. The dirty air which people of London are thereby forced to breathe instead of the clean air leads to increased instances of premature deaths.Did you know that in 1952, the smog which covered London in December was a combination of industrial pollution and high-pressure weather conditions!In order to make available clean air to the residents of London, it is extremely important to ensure that the quantity of particulate matter in the air is within the legal levels. Wherever the concentration of these pollutants and tiny particles is around illegal levels, immediate corrective action is required to reduce the health risk for children as well as adults in Greater London.Can electric cars reduce emissions caused by regular road transport? Can the health effects of air pollution be mitigated using cleaner vehicles? Read on to know more about the pollution levels in London and what the City Hall is doing to manage the menace of polluting vehicles. Afterward, also check Los Angeles pollution facts and air pollution facts.Health Impacts of Air PollutionDepending on the time and intensity of the exposure, different effects are produced. Short-term (a few hours) exposures to high amounts of nitrogen dioxide can irritate the airways, causing intense coughing and exacerbating existing respiratory infections, which is inconvenient at best and hazardous at worst for sensitive persons (sick and older or younger people, for example).Long-term exposure can result in a variety of ailments, including asthma, pulmonary disease, and lung cancer. It has also been demonstrated to prevent children’s lungs from growing normally. This is especially concerning because one-third of London’s schools have been shown to be located near busy highways with dangerously high nitrogen dioxide levels. New research is beginning to indicate a relationship between air pollution and cognitive performance. Some American study also shows that there is a relationship between air pollution and dementia, while research on this topic is still in its early stages, and further research is needed. Poor air quality, on the other hand, is clearly harmful to human health and must be addressed as soon as possible. Low air quality is also a social issue because those who reside in low-income regions are exposed to greater amounts of pollution on average.Air Pollution Exposure In LondonAir pollution is the most serious environmental health issue in the United Kingdom, with long-term exposure estimated to cause 28,000-36,000 premature deaths each year.The most important elements are the quality of housing and the features of the surrounding environment, taking into consideration location and levels of outdoor air pollution - aspects that inhabitants have no influence over.Air pollution is linked to numerous health issues, including respiratory and cardiovascular disorders, birth deformities, pediatric asthma episodes, and unexpected newborn deaths. Long-term exposure to particulate matter (PM) has been related to adult depression, although further study is needed.Cleaning London’s AirMayors have vowed to do more to address the situation in the past. Cleaner bus fleets, for example, have helped to reduce the statistics, but London continues to violate legal air pollution levels on a regular basis.Charges for the environment: While London’s Congestion Charge originally reduced congestion, it has already returned to pre-charge levels and has done almost nothing to improve air quality in the capital. On top of the congestion charge, the current Mayor of London has introduced two environmental programs for drivers of older cars. The T-Charge went into force in October 2017, although it was replaced in 2021 by the Congestion Charge Zone’s Ultra Low Emission Zone (ULEZ).Vehicles that are cleaner: We need to transition to low- and zero-emission cars, according to both the Mayor of London and the government. With the aid of a government-backed National Vehicle Scrappage Fund, the Mayor has appealed for support for companies and drivers – particularly those on low incomes – to replace older polluting cars with cleaner alternatives.However, we do not have to wait for the government to act. Instead, as we’ve already advocated, the Mayor might lead the way by putting part of the ULEZ earnings into a London cashback scrappage program. The most polluting drivers are those that pay the most under the ULEZ, therefore targeting them will have the greatest impact on air quality. They would also be the most motivated to take part in the plan. As an incentive to adopt alternative forms of transportation, the payback offer might be in the form of mobility credits.Fewer automobiles: We need not only cleaner automobiles, but also fewer vehicles on our roads in general, to have a long-term influence on air quality. While the transition to low- and zero-emission vehicles – particularly for buses, freight, and private hire vehicles – is critical to meeting air quality goals, we must not overlook the fact that non-tailpipe particulate emissions (from brakes, tires, and roadway) have been shown to be just as harmful to public health. By 2041, the Mayor’s Transport Strategy calls for 80% of all trips in London to be undertaken on foot, by bicycle, or by public transportation (up from 63% currently). This lofty goal is something we applaud. Getting people out of their automobiles will improve air quality as well as stimulate greater physical exercise, which will help to combat obesity-related disorders.According to the mayor of London’s report, which was examined by experts, more than 2 million individuals in the city breathed toxic air in 2016, but this number reduced to 119,000 in 2019. The data reveals that nitrogen dioxide (NO2) levels along roadways in central London reduced by 44% between early 2017 and early 2020, excluding the further reductions in pollution reported after the Covid-19 lockdown began in March.Car PollutionThe single most important source of air pollution in London is automobiles. They spew microscopic rubber and metal particles into the air we breathe, which are too small to detect with the human eye. They create over half of all nitrogen oxides.Despite recent improvements in air quality, toxic air pollution in London remains the greatest environmental threat to the health of all Londoners, hurting our lungs, exacerbating chronic illnesses such as asthma, lung and heart disease, and endangering the health of our children. According to a report from Imperial College London, nearly 4,000 Londoners died in 2019 as a result of poisonous air.In the next years, cities will be in the vanguard of combating air pollution and climate change, and addressing these twin concerns will need to hasten the transition to zero-emission cars. In the interim, driving a less polluting car or van helps to lower London’s hazardous air, so we’re assisting drivers in selecting cleaner ULEZ-compliant cars that satisfy the newest Euro requirements in the lab and on the road for dangerous nitrogen oxides (NOx).Vehicles frequently emit more NOx in real-world driving than during compliance testing in labs, according to evidence, especially in congested metropolitan locations like London. According to recent data from the Environmental Defense Fund Europe, nitrogen oxide (NOx) pollution from diesel cars is substantially greater outside of central London (EDF).Air Pollution Research In LondonThe researchers used Breathe London data to estimate NOx pollution from diesel cars at 231 sites around London and discovered that NOx pollution from diesel vehicles is 23% greater outside of London’s Ultra Low Emission Zone (ULEZ).Wembley in Brent, one of London’s poorest boroughs, was one of the places with the highest pollution concentrations. EDF has pointed out that the pollution is already having an impact on residents’ health; the proportion of young people aged 10-18 who require emergency admission for asthma in Brent is 57% greater than the national average.According to the researchers, this raises a warning signal for policymakers and underscores the risk of a car-led economic recovery, which would result in increased hazardous air pollution.Within the ‘Virtual London’ geographic information system, a framework for linking air pollution, traffic, and health-related data in the population.The ways in which air pollution diffuses inside central London’s building and street geometry, extending state of the art in the way air pollution is simulated regionally.Within the street and building geometry, a preliminary investigation of the spatial impact of pollution on the health of working and resident populations.Here at Kidadl, we have carefully created lots of interesting family-friendly facts for everyone to enjoy!
