Is it the responsibility to rent a residential property with excessive formaldehyde?

The residential property has the responsibility. But it depends on some circumstances.

At present, national standards require that the formaldehyde concentration in indoor living environment should be less than 0. 1mg/m3. Excessive formaldehyde will cause harm to human body, and relatively minor harm may be manifested as skin itching, rash, photophobia, tears, burning sensation, conjunctivitis, keratitis and so on. Severe formaldehyde poisoning can cause bronchitis, indigestion, chest tightness, dyspnea, and even symptoms of mental nervous system. Long-term chronic formaldehyde poisoning will also affect liver and kidney function, leading to liver failure. In addition, it will also affect the function of hematopoietic system, leading to leukopenia or thrombocytopenia, and leukemia will occur in severe cases.
