The article “How to deal with exposure to formaldehyde” (Sept 9) highlighted the dangers of formaldehyde found in furniture and building materials. However, a crucial aspect deserves further attention: It is also a significant component of cigarette smoke and e-cigarette vapour.
Cigarette smoke is a cocktail of harmful volatile organic compounds including benzene, toluene, and formaldehyde. These compounds irritate the respiratory system and can also affect the central nervous system.
Research shows cigarette smoke can contain high levels of formaldehyde, exceeding the limits recommended by the World Health Organisation for indoor air quality. This poses a serious health risk, particularly for those exposed to second-hand smoke daily.
Formaldehyde exposure from cigarettes can cause a range of health problems. Short-term exposure may lead to coughing, wheezing and shortness of breath. Chronic exposure can trigger more severe issues such as asthma, chronic bronchitis and even cancer.
Protecting public health requires a broader approach than just regulating furniture. We need to eliminate all sources of indoor air pollution, including smoking.
While good ventilation is key, residents living near smokers often have to keep windows closed to avoid second-hand smoke, creating a trap for harmful substances. Poor ventilation allows formaldehyde to accumulate over time, especially when combined with high temperatures and humidity.
Dr Jonathan Tang, who was quoted in the report, emphasised that children are particularly vulnerable because formaldehyde, being heavier than air, tends to settle closer to the ground. Furthermore, it can cling to surfaces and can be costly and difficult to remove entirely. Therefore, preventing its formation in the first place is crucial.
Given the substantial health risks, a multi-pronged approach is necessary. The Government should continue efforts to limit formaldehyde in building materials, but also address cigarette smoke.
Public awareness campaigns should educate residents about the dangers of being exposed to formaldehyde from smoking. Additionally, stricter regulations on smoking in enclosed spaces, especially multi-unit housing, are essential to protect non-smokers from second-hand smoke exposure.
By taking a comprehensive approach, we can create safer living environments and protect the public from the hidden dangers of formaldehyde, both in furniture and in the air we breathe.
