USC study associates PM2.5 air pollution with poor survival in liver cancer patients

Green Car Congress

A study by researchers at the University of Southern California (USC) has significantly associated exposure to particulate air pollution after being diagnosed with liver cancer with an increased risk of premature death. exposure after diagnosis was statistically significantly associated with HCC survival. —Deng et al.

Study: traffic density, wind and air stratification influence concentrations of NO2

Green Car Congress

In connection with the effects of the COVID-19 pandemic, satellite measurements made headlines showing how much the air pollutant nitrogen dioxide (NO 2 ) had decreased in China and northern Italy. The statistical analysis has also enabled the researchers to remove the influence of the weather from the time series of pollutant concentrations.

Study finds significant slowdown in decrease of NOx emissions in US; implications for air quality management

Green Car Congress

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. We were surprised by the discrepancy between the estimates of emissions and the actual measurements of pollutants in the atmosphere.

Fujitsu verifies AI technology for predicting vessel collision risks in marine traffic control

Green Car Congress

According to a report by the Japan Transport Safety Board, there were 2,863 marine collision accidents in Japan alone between 2009 and 2019, with an average of 286 accidents per year. Collisions involving large vessels can have a major impact on society, in terms of crew safety, damage to vessels, and marine pollution.

Opinion: Reinventing fuel-based power for a more secure and resilient grid

Green Car Congress

It is argued, therefore, that with this power potential, we can create enough excess in wind and solar power that the statistical likelihood of not having the power supply to match demand is effectively zero. European Environment Agency, 2009. [ 2 ] Swart, R.

Study Finds Damage, Pollution from Western Wildfires Could Surge With Moderate Global Warming

Green Car Congress

This potential leap in destructiveness and pollution—mainly from an increase in wildfire frequency—is forecast by computer models calculating impacts of moderate global warming on western US wildfire patterns and atmospheric chemistry. Jennifer Logan. Their new work could help policymakers gauge how severe that penalty might become.

CRC study finds some adverse results from use of mid-level ethanol blends in MY 2001-2009 engines; DOE and ethanol industry say study significantly flawed

Green Car Congress

Growth Energy, an ethanol industry trade group, petitioned the EPA in March 2009 to raise the limit on ethanol in gasoline from 10 to 15 percent. EPA’s decision was based largely on a DOE study of the effects of E15 on durability of catalytic converters, the primary pollution control system in a vehicle. Background. Earlier post.)
