Carbon monoxide in school buses.

Seats on school buses.

Biological signaling by carbon monoxide and carbon monoxide-releasing molecules.

Carbon monoxide (CO) is continuously produced in mammalian cells during the degradation of heme. It is a stable gaseous molecule that reacts selectively with transition metals in a specific redox state, and these characteristics restrict the interaction of CO with defined biological targets that transduce its signaling activity. Because of the high affinity of CO for ferrous heme, these targets...

School buses, diesel emissions, and respiratory health.

School buses contribute disproportionately to ambient air quality, pollute near schools and residential areas, and their emissions collect within passenger cabins. This paper examines the impact of school bus emissions reductions programs on health outcomes. A key contribution relative to the broader literature is that we examine localized pollution reduction programs at a fine level of aggrega...

Victim of carbon monoxide poisoning identified by carbon monoxide oximetry.

BACKGROUND Carbon monoxide (CO) is known as a leading cause of unintentional poisoning death in many countries. Diagnosis is usually made by measuring carboxyhemoglobin (COHb), but due to the non-specific symptoms, the crucial step is considering CO poisoning. A possible solution might be screening emergency department (ED) patients. A cutaneous sensor that measures oxygen and CO saturation sim...

Should School Buses Have Seat Belts?

1. I NI Of the 42,000 people killed in traffic accidents, only 6 are children on school buses. 2. I NI School buses are safe enough already. 3. I NI High-backed seats on school buses help to “package children like eggs.” 4. I NI Lap and shoulder belts reduce injuries by 45 percent. 5. I NI Padded seats are all that is needed to protect students from harm. 6. I NI Buses are seven times safer tha...
