The efficiency of EURO 6d car particulate filters is compromised by atmospheric aging: In vitro toxicity of gasoline car exhaust.

Tailpipe emissions from road traffic contribute substantially to the burden of fine inhalable particulate matter (PM) and deteriorate air quality. Exhaust emission standards, forcing improvements in combustion and exhaust after-treatment technology, considerably decreases combustion-related PM emitted by modern cars. A549 cancerous alveolar and BEAS-2B normal bronchial epithelial cells were exposed at the air-liquid interface to the total aerosol or gas phase of either fresh or photochemically aged tailpipe emissions from a gasoline EURO 6d car equipped with a gasoline particulate filter.

Environmental exposure of humans to bromide in the Dead Sea area: Measurement of genotoxicy and apoptosis biomarkers.

Bromide (Br) is a bromine atom with a negative charge which is released mainly in the production of pesticides and flame retardants. It is also found naturally in seawater. Br¯ has been associated with many detrimental effects such as respiratory problems, gastric hemorrhages, and dermal burns.
