Impact of Warehouse Expansion on Ambient PM and Elemental Carbon Levels in Southern California's Disadvantaged Communities: A Two-Decade Analysis. | LitMetric

AI Article Synopsis

  • - Over the past 20 years, increased warehouse construction near seaports and low-cost land has led to higher transportation and e-commerce activities, negatively impacting air quality and health in nearby disadvantaged communities.
  • - A study from 2000 to 2019 in Southern California found that larger warehouses (measured by rentable building area, loading docks, and parking spaces) were linked to increased pollution levels of particulate matter (PM) and elemental carbon (EC).
  • - Data revealed that an increase in warehouse size and facilities led to significant rises in PM and EC concentrations, with disadvantaged populations facing higher pollution exposure and related health risks.

Article Abstract

Over the past two decades, the surge in warehouse construction near seaports and in economically lower-cost land areas has intensified product transportation and e-commerce activities, particularly affecting air quality and health in nearby socially disadvantaged communities. This study, spanning from 2000 to 2019 in Southern California, investigated the relationship between ambient concentrations of PM and elemental carbon (EC) and the proliferation of warehouses. Utilizing satellite-driven estimates of annual mean ambient pollution levels at the ZIP code level and linear mixed effect models, positive associations were found between warehouse characteristics such as rentable building area (RBA), number of loading docks (LD), and parking spaces (PS), and increases in PM and EC concentrations. After adjusting for demographic covariates, an Interquartile Range increase of the RBA, LD, and PS were associated with a 0.16 μg/m³ (95% CI = [0.13, 0.19],  < 0.001), 0.10 μg/m³ (95% CI = [0.08, 0.12],  < 0.001), and 0.21 μg/m³ (95% CI = [0.18, 0.24],  < 0.001) increase in PM, respectively. For EC concentrations, an IQR increase of RBA, LD, and PS were each associated with a 0.021 μg/m³ (95% CI = [0.019, 0.024],  < 0.001), 0.014 μg/m³ (95% CI = [0.012, 0.015],  < 0.001), and 0.021 μg/m³ (95% CI = [0.019, 0.024],  < 0.001) increase. The study also highlighted that disadvantaged populations, including racial/ethnic minorities, individuals with lower education levels, and lower-income earners, were disproportionately affected by higher pollution levels.
