Summary
This summary is machine-generated.Cleaner diesel trucks under Port Drayage Truck Replacement Programs (TRPs) had mixed air quality impacts. Black communities near ports saw worsening NO2 levels, while Hispanic communities experienced improvements.
Area Of Science
- Environmental Science
- Public Health
- Urban Planning
Background
- Port operations significantly contribute to local air pollution.
- Disadvantaged communities often bear a disproportionate burden of environmental hazards.
- The Port Drayage Truck Replacement Programs (TRPs) aimed to mitigate pollution from diesel trucks.
Purpose Of The Study
- To evaluate the impact of TRPs on local air quality in disadvantaged neighborhoods near ports.
- To assess differential effects of TRPs on Black/African American and Hispanic/Latino communities.
- To identify policy recommendations for reducing environmental health disparities.
Main Methods
- Utilized annual air pollutant data and census demographics at the tract level.
- Employed a Difference-in-Differences-in-Differences (DDD) model to estimate air quality changes.
- Compared air quality trends in near-port areas with Greater New York (GNY) as a control.
Main Results
- TRPs had mixed effects: Black communities near ports experienced higher NO2 levels (6.4% more than GNY Black tracts), while Hispanic communities saw improvements.
- Within near-port areas, Black-majority tracts had 2.7% higher NO2 than non-Black-majority tracts.
- The relative NO2 gap widened for Black populations but narrowed for Hispanic populations compared to GNY.
Conclusions
- TRPs created disparities, with Black communities experiencing negative outcomes and Hispanic communities benefiting.
- Targeted interventions and an integrated policy approach are crucial for environmental justice.
- Recommendations include standardized truck regulations, stricter emission controls, and accelerated adoption of electric/hydrogen vehicles.

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
Agricultural Bioremediation
Bioremediation is a useful process in which microbes and bacteria are used to remove toxins and pollutants from the environment. In agricultural practices, the use of fertilizers and pesticides can result in leaching of...
Concrete in large quantities can be pumped across long distances for placing in inaccessible sites. This system comprises a hopper that receives concrete from a mixer, a pump to propel the concrete, and pipelines that facilitate its delivery.
For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...
