為降低新裝修居室內污染氣體對人體健康的影響，針對新裝修居室內空氣污染特征展開分析。通過實際監(jiān)測，獲得裝修后居室內甲醛、苯、甲苯和總揮發(fā)性有機物的濃度，并從時間分布、空間分布、時間角度分析空氣污染特征和衰減變化。根據特征分析結果，選擇空氣凈化器處理與室內通風相結合的凈化措施，降低空氣污染濃度。由實際監(jiān)測結果可以看出，隨著空氣凈化器運行次數的增加，新裝修的居室內甲醛、苯系物和揮發(fā)性有機物的濃度都有所下降，隨著污染物清潔率的提高，居室內空氣清潔率也明顯提高，說明上述提出的凈化措施有效。

To reduce the impact of polluted gases on human health in newly renovated homes, an analysis is conducted on the characteristics of air pollution in newly renovated homes. Through actual monitoring, the concentrations of formaldehyde, benzene, toluene, and total volatile organic compounds in the decorated living room are obtained, and the characteristics and attenuation changes of air pollution are analyzed from the perspectives of time distribution, spatial distribution, and time. Based on the results of feature analysis, choose a purification measure that combines air purifier treatment with indoor ventilation to reduce air pollution concentration. From the actual monitoring results, it can be seen that with the increase of the operation frequency of the air purifier, the concentrations of formaldehyde, benzene derivatives, and volatile organic compounds in newly renovated rooms have decreased. With the improvement of pollutant cleaning rate, the air cleanliness rate in the room has also significantly increased, indicating that the purification measures proposed above are effective.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a method for determining benzene derivatives in ambient air using Tenax composite solid adsorption/thermal desorption combined with gas chromatography; The calibration curve of this method has good linearity. When the sampling volume is 1 L, the detection limit of each component is 2.9 × 10-4~4.9 × 10-4mg/m3; This method has high sensitivity, accuracy and reliability, and is easy to operate, suitable for the determination of benzene derivatives in ambient air.
