Characteristics: colorless, with strong pungent smell and volatile gas. ? Standard: The national standard specifies the indoor formaldehyde concentration.
2. Benzene-the second killer? Sources: Latex paint, paint, synthetic fiber, additives and diluents of various paints and coatings, solvent-based adhesives, waterproof materials. ? Characteristics: colorless or yellow oil, with special aromatic gas, volatile and flammable. ? Standard: The national standard stipulates that indoor benzene ≤0. 1 1mg/m3 toluene ≤0.2mg/m3 xylene concentration ≤0.2mg/m3 meets the standard. ? Hazards: Carcinogenic substances, mild poisoning can cause drowsiness, headache, dizziness, nausea, chest tightness, insomnia, listlessness and memory loss, while severe poisoning can cause blurred vision, shallow and rapid breathing, arrhythmia, convulsions and coma, fetal birth defects and other serious diseases. ?

Hazards: tears, sore throat, hoarseness, cough, bloodshot sputum, chest tightness, dyspnea, dizziness, headache, nausea, vomiting, fatigue, severe pulmonary edema, adult respiratory distress syndrome. ? Dietary recommendation: black bean porridge with red bean and coix seed can induce diuresis to eliminate edema and has strong detoxification ability.
4. Radon-the fourth killer? Source: radioactive elements contained in soil, concrete, brick sand cement, gypsum board, granite and stone. ? Characteristics: radioactive inert gas, colorless and odorless. ? Standard: indoor radon concentration ≤400Bq/m3 according to the national standard. ? Hazard: It is easy to enter the respiratory system, gradually destroy lung cells and tissues, and form internal irradiation, which is the second largest factor inducing lung cancer after smoking. ? Food recommendation: Mushroom soup, stewed with all kinds of common mushrooms, can be stewed with eggs or tofu. It's not greasy. It's delicious.
5. Total volatile organic compounds-the fifth biggest killer? Sources: Paint, particleboard, plywood, foam filler, interior wall coating, plastic and stone veneer. ? Characteristics: It may have odor, toxicity and irritation. ? Standard: National standard: indoor TVOC≤0.60mg/m3 as the standard. ? Hazard: The volatile liquid or solid organic substances at room temperature are collectively called TVOC, mainly radioactive substances produced by radioactive elements such as radium and thorium during the decay process. It can cause leukopenia, damage the nervous system, reproductive system and digestive system and cause cancer. ? Dietary suggestion: steamed pig blood+tofu is easy to cook, rich in plant protein to improve the body's immunity, and pig blood excretes toxins, which is a good cooking method. High nutritional value.
