Hazardous Substances in Container Houses

The hazardous substances that may exist in container houses mainly include volatile organic compounds (VOCs) such as formaldehyde and benzene, as well as asbestos dust that may be present in old container houses.

Formaldehyde is one of the most common hazardous substances in container houses, primarily originating from materials such as paints, panels, and glues used, especially those containing formaldehyde and low-quality panels. Formaldehyde has a pungent odor, and long-term exposure can lead to health issues such as respiratory distress, eye irritation, skin allergies, nervous system damage, and a weakened immune system. Data shows that approximately 65% of non-standard modified container houses have formaldehyde levels exceeding standards. This indicates that if non-environmentally friendly materials are used during the construction or modification of container houses, the risk of formaldehyde exceeding standards will significantly increase, posing a serious threat to the health of occupants.

Benzene is another harmful volatile organic compound that has adverse effects on human health. The commonly used polystyrene foam insulation material in container houses continuously releases benzene and formaldehyde under high-temperature conditions. Benzene is highly volatile and tends to accumulate in indoor air. Long-term inhalation may trigger blood diseases such as leukemia.

Asbestos dust is mainly found in some old container houses that may have used asbestos insulation materials. Once inhaled, asbestos dust deposits in the lungs, causing pulmonary fibrosis, a difficult-to-cure lung disease. The International Agency for Research on Cancer has classified asbestos as a Group 1 carcinogen. Therefore, for old container houses, it is essential to be particularly vigilant about the hazards of asbestos dust and avoid long-term residence or frequent contact.

To reduce the hazards of hazardous substances in container houses, it is recommended to choose environmentally friendly materials during construction or modification to ensure that indoor air quality meets standards. At the same time, old container houses should undergo comprehensive testing and evaluation to ensure the absence of hazardous substances such as asbestos before being used.
