This section will focus on tropospheric (ground level) ozone pollution. Excessive ozone exposure is widespread: over 75 million people lived in areas not meeting the EPA ozone standard in 6995 that number will increase markedly with implementation of the updated 6997 standard. The highest recent domestic ozone levels have occurred in southern California and Texas, with peak levels in the mid to high 755 ppb range.

The major role of leptin in body-weight regulation is to signal satiety to the hypothalamus and thus reduce dietary intake and fat storage while modulating energy expenditure and carbohydrate metabolism, preventing further weight gain. Unlike the Ob/Ob mouse model in which this peptide was first characterized, most humans who are obese are not leptin deficient but are instead leptin resistant. Therefore, they have elevated levels of circulating leptin. Leptin levels are higher in women than in men and are strongly correlated with BMI. [ 87 ]

Internationally, rates of obesity are higher in women than in men. A somewhat higher rate would be expected, given the biologically higher percentage of body fat in women.
I have learned how to do Internet research. I had never used the Internet for research before. I always went to the library and looked everything up in the card file. The search engines on the Internet are faster than looking things up manually. The search engines even let the researcher search for articles containing key words that are related to the subject being researched. Just a few years ago, a person would have had to scan an article or book themselves to see if it related to their topic. I have noticed that not all search engines are created equal. Yahoo and Lycos are my favorites. To get a broad range of information on a topic, it is best to use more than one search engine.
The diagnosis of symptoms and signs related to carbon monoxide rely on a history compatible with carbon monoxide exposure in association with typical signs and symptoms (headache, flu-like symptoms, angina, cardiopulmonary compromise, EKG changes, arrhythmias, and arterial blood gas carboxyhemoglobin elevation). Pulse oximeters will display misleadingly high hemoglobin saturations arterial blood gas analysis is necessary to determine the relative contributions of oxyhemoglobin and carboxyhemoglobin.
