China study connects ozone pollution to cardiovascular health

Green Car Congress

Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. The findings associated ozone exposure with markers of platelet activation and increased blood pressure.

Study finds that unregulated VSLS efficient at influencing climate through depletion of stratospheric ozone

Green Car Congress

Although halogens released from long-lived anthropogenic substances, such as chlorofluorocarbons (CFCs), are the principal cause of the recent depletion of stratospheric ozone, recent observations show that very short-lived substances (VSLS), with lifetimes generally under six months, are also an important source of stratospheric halogens.

UCI-led study finds California’s strict air quality regulations have helped farmers

Green Car Congress

Researchers at the University of California, Irvine and other institutions have conducted a statistical analysis of pollution exposure and yields from 1980 to 2015 on a key sector making up about 38% of the state’s total agricultural output: perennial crops such as almonds, grapes, nectarines, peaches, strawberries and walnuts.

Emissions of potent GHG HFC-23 have grown, contradicting reports of huge reductions

Green Car Congress

Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. This would have been a big win for climate. —co-author Dr Matt Rigby.

Study finds some refrigerants less damaging to ozone layer can degrade to long-lived GHG CF4

Green Car Congress

Some of the substitutes for ozone-damaging chemicals that being phased out worldwide under international agreements are themselves potent greenhouse gases and contribute to warming. This work was supported in part by NOAA’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) Program and NASA’s Atmospheric Composition Program.

New international study finds lab testing of diesel NOx emissions underestimates real-world levels by up to 50%

Green Car Congress

in collaboration with scientists at the University of York’s Stockholm Environment Institute (SEI); University of Colorado; and the International Institute for Applied Systems Analysis, assessed 30 studies of vehicle emissions under real-world driving conditions in 11 major vehicle markets representing 80% of new diesel vehicle sales in 2015.

Study: air pollution causes 800,000 extra deaths a year in Europe and 8.8 million worldwide

Green Car Congress

Using a new method of modeling the effects of various sources of outdoor air pollution on death rates, the researchers found that it caused an estimated 790,000 extra deaths in the whole of Europe in 2015 and 659,000 deaths in the 28 Member States of the European Union (EU-28). million deaths in 2015. They focused particularly on PM 2.5
