Particulate Pollution in Underground Restaurants Due to Prefabricated Dish Preparation
Particulate matter (PM) is recognized as a major air pollutant with significant adverse effects on human health worldwide. In underground restaurants in China, the growing reliance on prefabricated dishes has raised concerns about indoor particulate pollution. Limited natural ventilation, confined spaces, and intensive cooking activities may exacerbate the accumulation of PM, creating elevated exposure risks for both employees and customers. Understanding the levels and sources of particulate pollution in these settings is essential for developing effective health protection and pollution control strategies. Research Objective This study aims to address the existing research gap regarding particulate pollution in underground restaurants arising from the preparation of prefabricated dishes. Specifically, it seeks to systematically measure PM concentrations across different types of underground spaces and to identify the key factors influencing indoor particulate levels. By providing ...
