Context
- Industrial parks are significant sources of volatile organic compounds (VOCs).
- Accurate estimation of VOC emission strengths at an industrial park scale is crucial for effective pollution control.
- Existing methods may lack the precision needed for targeted emission reduction strategies.
Purpose
- To establish a robust method for estimating volatile organic compound (VOC) emission strengths from enterprises within an industrial park.
- To utilize small-scale air quality modeling (ADMS) combined with mobile monitoring data for source apportionment.
- To provide hourly emission strength data for key enterprises in a real-world industrial zone.
Summary
- A novel VOC source estimation method was developed using ADMS and mobile monitoring data, incorporating hourly meteorological data to identify emission sources based on wind direction.
- Simulation results from ADMS were compared with observed concentrations to quantify VOC source strengths, with inversion experiments conducted using data from Shenyang Economic Development Zone.
- The study identified peak VOC emission periods and sources, particularly from furniture manufacturing, and found emissions exceeding 100 g·s⁻¹ in three enterprises. Model validation showed good correlation between simulated and observed values.
Impact
- Provides a novel and scientifically validated approach for quantifying VOC emission strengths in industrial parks.

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:
Conducting Experiments:
The first step is to conduct experiments by systematically varying the input variables. This is typically done using a specific experimental design, such as a factorial...
Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...
Individual molecules in a gas move in random directions, but a gas containing numerous molecules has a predictable distribution of molecular speeds, which is known as the Maxwell-Boltzmann distribution, f(v).
This distribution function f(v) is defined by saying that the expected number N (v1,v2) of particles with speeds between v1 and v2 is given by
Since N is dimensionless and the unit of f(v) is seconds per meter, the equation can be conveniently modified into a...
Atomic absorption spectroscopy (AAS) relies on the Beer-Lambert law, which requires that the radiation source emits a narrow range of wavelengths to match the absorption characteristics of the analyte atom. The primary criteria for choosing an appropriate radiation source in AAS is to provide a precise and intense emission at specific wavelengths that will allow accurate detection of the analyte.
Two common narrow-range 'line' sources used in AAS are hollow-cathode lamps (HCLs) and...
AES is a powerful analytical technique, especially effective when used with plasma sources, producing abundant spectra in characteristic emission lines. The Inductively Coupled Plasma (ICP), in particular, yields superior quantitative analytical data due to its high stability, low noise, low background, and minimal interferences under optimal experimental conditions. However, newer air-operated microwave sources are emerging as promising alternatives that could be more cost-effective than...
Air content measurement in concrete is critical for ensuring structural integrity and durability of concrete structures, especially in environments prone to severe weather conditions. Accurate air content analysis optimizes concrete's resistance to freeze-thaw cycles and enhances its workability and strength. Several methods are standardized under ASTM guidelines to measure the air content in fresh concrete, each suitable for different concrete types and conditions.
The pressure method,...
