How One Commonly Used Asthma Inhaler is Damaging the Planet

If there is any field of science that understands the doctrine of unintended consequences, it’s medicine. We rely on antibiotics to wipe out infections, and in the process breed a class of superbugs resistant to the drugs. We develop powerful medications that can control chronic pain, and in the U.S., have a nationwide addiction crisis to show for that breakthrough. Now, it appears, we can add asthma control to the list pharmaceutical blowbacks we didn’t see coming. According to a new study published in BMJ Open, the familiar lightweight, pocket-sized aerosolized inhalers that make breathing easier for so many of the 235 million people worldwide who suffer from asthma may be choking the planet on a powerful greenhouse gas they release in the process. The study, led by Dr. Alexander JK Wilkinson, a respiratory specialist with Britain’s National Health Service, focused on the 4.67 million people diagnosed with asthma in the United Kingdom, but it has implications for treatment worldwide, including in the U.S., where 22.6 million people (6.1 million of them children) are afflicted with the condition. The researcher compared the greenhouse gas emissions of aerosol pumps—known as metered dose inhalers (MDI)—with dry powder inhalers (DPI), which are shaped something like a hockey puck and are activated simply by inhaling. The two weren’t even close. The problem with MDIs is not carbon dioxide (the most common greenhouse gas), but rather methane...

CONCLUSIONS: The device, which combined 20 g of CELOX particles and 20 pieces of CELOX (8 g) sponge tablets with 50-mmHg intra-abdominal compression for 10 minutes, prolonged the ST by an average of 30 minutes with less BL. It was not markedly different from the full four quadrants gauze packing of liver in hemostatic effect, with no CELOX clot formation in other organs.

ConclusionThe acute toxicity associated with oral selenium ingestion and the blood and urinary levels of selenium in different cases of poisonings were reviewed. Mortality is a risk of acute selenium poisoning. Concentrations of selenium in blood and urine samples in non-fatal cases are close to those observed in fatal cases.
