Toxic Potencies of Particulate Matter from Typical Industrial Plants Mediated with Acidity via Metal Dissolution.

Environmental Science and Technology
Acidity is an important property of particulate matter (PM) in the atmosphere, but its association with PM toxicity remains unclear. Here, this study quantitively reports the effect of the acidity level on PM toxicity via pH-control experiments and ...

Geochemistry of hot-springs at the SuSu Knolls hydrothermal field, Eastern Manus Basin: Advanced argillic alteration and vent fluid acidity

Geochimica et Cosmochimica Acta, 2019
SuSu Knolls is an area of ongoing magmatic activity and recent volcanism located in the back-arc spreading environment of the Manus Basin in the Bismarck Sea, Papua New Guinea. In 2006, hydrothermal fluids were collected from three areas of submarine hot-

Citric Acid Aerosol As a Potential Smoking Cessation Aid

Chest, 1987
We tested the ability of a citric acid aerosol to simulate the tracheal sensations produced by cigarette smoke and to satisfy smokers' desire for cigarettes. Fifteen smokers rated puffs from their own brand of cigarette, citric acid aerosol, a low tar and nicotine cigarette, and air.

Review of health effects driven by aerosol acidity: Occurrence and implications for air pollution control.

Science of the Total Environment
Acidity, generally expressed as pH, plays a crucial role in atmospheric processes and ecosystem evolution. Atmospheric acidic aerosol, triggering severe air pollution in the industrialization process (e.g., London Great Smoke in 1952), has detrimental ...

Asiatic acid inhibits pulmonary inflammation induced by cigarette smoke

International Immunopharmacology, 2016
Asiatic acid (AA) is one of the major components of Titrated extract of Centella asiatica (TECA), which has been reported to possess antioxidant and anti-inflammatory activities. The purpose of this study was to investigate the protective effect of AA on pulmonary inflammation induced by cigarette smoke (CS).

Cigarette smoking, gastric acidity and peptic ulceration

Digestive Diseases and Sciences, 1990
The influence of cigarette smoking on intragastric acidity was assessed in duodenal ulcer patients in symptomatic remission and in healthy volunteers in a retrospective study. Continuous 24-hr pH recordings in 150 nonsmokers and 174 smokers receiving placebo treatment were compared.
