富阳青何村臭氧数据

根据国家标准要求，臭氧也是评判空气质量的重要指标之一。通过对臭氧检测，可以了解环境空气的质量、污染状况，为环境管理和环境保护提供科学依据，有助于实现可持续发展和生态环境的保护与改善。1、数据来源:按照环境空气 臭氧的测定 靛蓝二磺酸钠分光光度法 HJ 504-2009 及修改单采集环境空气样品并进行检测。2、算法规则: 按照如下公式进行计算:ρ=(Ao-A-a)*V*D/b/Vr，式中ρ为空气中臭氧浓度，单位mg/m³；A为样品的吸光度；A0为现场空白样品的吸光度；a为标准曲线的截距；b为标准曲线的斜率；V为样品溶液的总体积，单位m1；Vr为换算为参比状态的采样标态体积，单位：L；V为稀释倍数。3、数据判定:根据《环境空气质量标准》（GB 3095-2012）中的二级浓度限值进行判定，即臭氧浓度≤200μg/m³则为合格，反之则不合格。4、数据应用：通过分析空气中的臭氧浓度，我们可以判断该地环境空气受污染程度，为监管提供依据。

As required by national standards, ozone is one of the key indicators for air quality assessment. Ozone detection helps obtain information on the quality and pollution status of ambient air, providing scientific basis for environmental management and environmental protection, and facilitating sustainable development as well as the protection and improvement of the ecological environment.
1. Data Source: Ambient air samples are collected and tested in accordance with the Indigo Disulfonate Spectrophotometric Method for the Determination of Ozone in Ambient Air (HJ 504-2009) and its amendment.
2. Algorithm Rules: Calculations are conducted using the following formula: ρ=(A₀ - A - a) × V × D / (b × Vr). In this formula, ρ represents the ozone concentration in ambient air, with the unit of mg/m³; A is the absorbance of the sample; A₀ is the absorbance of the field blank sample; a is the intercept of the standard calibration curve; b is the slope of the standard calibration curve; V is the total volume of the sample solution, with the unit of mL (note: the original Chinese text had a typo "m1" which is presumably milliliters); Vr is the sampling volume converted to the standard reference state, with the unit of L; and the final V refers to the dilution multiple (note: the original text repeated the variable symbol V, which may be a typo).
3. Data Judgment: The evaluation is carried out based on the Grade 2 concentration limit specified in the Ambient Air Quality Standard (GB 3095-2012). Specifically, an ozone concentration of ≤ 200 μg/m³ is classified as qualified, while concentrations exceeding this threshold are considered unqualified.
4. Data Application: By analyzing the ozone concentration in ambient air, the pollution level of the local ambient air can be evaluated, providing supporting evidence for environmental supervision and management.
