Regularly using bleach linked to higher risk of fatal lung disease

Use of disinfectants once a week could increase risk of developing chronic obstructive pulmonary disease by as much as 32%, finds study

Regular use of bleach and other common disinfectants has been linked to a higher risk of developing fatal lung disease, researchers have found.
The use of disinfectants is linked to a higher risk of developing chronic obstructive pulmonary disease (COPD), according to research looking at incidence of the disease in more than 55,000 nurses in the US.
The 30-year study by Harvard University and the French National Institute of Health and Medical Research (Inserm) found that those who used the products just once a week had as high as a 32% increased chance of developing the condition.



COPD, which affects an estimated 1.2 million people in the UK, describes a group of lung conditions such as emphysema and chronic bronchitis that make it difficult to move air in and out of the lungs because the airways have been narrowed.
Nearly 25,000 people per year die from the disease in England, which is the third highest death rate in Europe.
Disinfectant use has previously been associated with an increased risk of respiratory problems such as asthma. However, the new study is thought to be the first to identify a link between COPD and specific cleaning chemicals known as quaternary ammonium compounds (quats).
“The potential adverse effects of exposure to disinfectants on COPD have received much less attention, although two recent studies in European populations showed that working as a cleaner was associated with a higher risk of COPD,” said Inserm researcher Orianne Dumas.
“To the best of our knowledge, we are the first to report a link between disinfectants and COPD among healthcare workers, and to investigate specific chemicals that may underlie this association.” 
The everyday use of bleach currently has no specific health guidelines, but the researchers hope this will be investigated.
“Some of these disinfectants, such as bleach and quats, are frequently used in ordinary households, and the potential impact of domestic use of disinfectants on COPD development is unknown,” Dumas said. “Earlier studies have found a link between asthma and exposure to cleaning products and disinfectants at home, such as bleach and sprays, so it is important to investigate this further.”
The researchers analysed data from a mass study on female US nurses commenced by Harvard in 1989. In 2009, they looked at those who were still working as nurses who had no history of COPD and tracked them until May this year. During that period, 663 were diagnosed with the condition.
The nurses’ exposure to disinfectants were evaluated via a questionnaire and other factors that could have distorted the results, such as the age, weight and ethnicity of the subjects, were taken into account.
On Monday, Dumas will tell a meeting of the European Respiratory Society International Congress in Milan that certain tasks involving frequent exposure to disinfectants, such as cleaning surfaces, as well as specific chemicals in disinfectants, were associated with a 22-32% increased risk of developing the disease.
Dumas will say: “We found that nurses who use disinfectants to clean surfaces on a regular basis – at least once a week – had a 22% increased risk of developing COPD ... There was a suggestion of a link with the weekly use of disinfectants to clean instruments but this was not statistically significant.
“In our study population, 37% of nurses used disinfectants to clean surfaces on a weekly basis and 19% used disinfectants to clean medical instruments on a weekly basis.”
She says the findings highlight the need for guidelines for cleaning and disinfection in healthcare settings such as hospitals to be updated to take the occupational health risks into account.

Cleaning the house with bleach could lead to fatal lung disease 



Using bleach and other common disinfectants to clean the house puts people at risk of fatal lung conditions, research has suggested.
A 30-year study of more than 55,000 women found those who used the products just once a week had a 32 per cent increased chance of developing chronic obstructive pulmonary disease (COPD).
The debilitating and often agonising illness, which can include bronchitis and emphysema, was linked to long-term use of quaternary ammonium compounds, known as “quats”, which are found in everyday floor and surface disinfectants.
Products containing alcohol, hydrogen peroxide and bleach were also associated with the disease, which is most commonly diagnosed in heavy smokers and those who have suffered long-term exposure to dust and pollution.
Disinfectant use has been associated with an increased risk of asthma previously. However, the new study by Harvard and the French National...

Regular use of disinfectant cleaning products has been linked to an increased risk of developing fatal lung conditions



Using products once a week found to potentially increase a person's chance of developing chronic obstructive pulmonary disease (COPD) by nearly a third

The regular use of disinfectant cleaning products such as bleach has been linked to an increased risk of developing fatal lung conditions, researchers said.
A study by Harvard University and the French National Institute of Health and Medical Research (Inserm) found that using the products just once a week could increase a person's chance of developing chronic obstructive pulmonary disease (COPD) by nearly a third.
The research involved data from more than 55,000 nurses in the US, and scientists looked at exposure to specific disinfectants, including bleach, hydrogen peroxide, alcohol and chemicals known as quaternary ammonium compounds (quats), which are often used to disinfect surfaces such as floors and furniture.
All of these were associated with an increased risk of COPD of between 24 per cent to 32 per cent in the study.
COPD is an umbrella term for a series of conditions affecting the lungs including emphysema, chronic bronchitis and chronic asthma.
The condition affects an estimated 1.2 million people in the UK, with nearly 30,000 people dying from the disease each year.
Previous studies have linked exposure to disinfectants with breathing problems such as asthma, but it is believed this is the first piece of research to identify a link between disinfectants and COPD.
Dr Orianne Dumas, a researcher at Inserm, said: “The potential adverse effects of exposure to disinfectants on COPD have received much less attention, although two recent studies in European populations showed that working as a cleaner was associated with a higher risk of COPD.
“To the best of our knowledge, we are the first to report a link between disinfectants and COPD among healthcare workers, and to investigate specific chemicals that may underlie this association.”
Dr Dumas will present the findings at the European Respiratory Society International Congress in Milan on Monday, where she will highlight that further research is needed to clarify the impact of disinfectant use in the home.
She added: “In particular, we need to investigate the impact on COPD of lifetime occupational exposure to chemicals and clarify the role of each specific disinfectant.
“Some of these disinfectants, such as bleach and quats, are frequently used in ordinary households, and the potential impact of domestic use of disinfectants on COPD development is unknown.
“Earlier studies have found a link between asthma and exposure to cleaning products and disinfectants at home, such as bleach and sprays, so it is important to investigate this further.”
As part of the research, scientists looked at 55,185 female registered nurses enrolled in the US Nurses' Health Study II, which began in 1989.
They looked at those nurses who were still in a nursing job and with no history of COPD in 2009, and then followed them for approximately eight years until May 2017.
During that time 663 nurses were diagnosed with COPD.
The nurses' exposure to disinfectants was evaluated via a questionnaire and other factors that could have distorted the results, such as the age, weight and ethnicity of the subjects, were taken into account.
