Which of the following can lead to indoor air quality issues in a home?

Smoking indoors is a significant contributor to indoor air quality issues in a home. When tobacco is smoked, it releases a complex mixture of harmful chemicals into the air, including nicotine, tar, and various carcinogens. This not only affects the smoker but also poses serious health risks to non-smokers who may be exposed to secondhand smoke. The particles and gases from cigarette smoke can linger in the air and settle on surfaces, resulting in persistent odor and potential respiratory problems for everyone in the household.

In contrast, eco-friendly cleaning products are designed to minimize harmful emissions and environmental impact, making them less likely to compromise indoor air quality. Regular ventilation helps to improve air circulation and reduce the concentration of indoor pollutants. Limiting clutter can also contribute to better airflow and reduce dust accumulation, which further mitigates IAQ issues.
