Mercury is released into the atmosphere when coal is burned (Figure 1.1). But breathing the mercury is not harmful. In the atmosphere, the mercury forms small droplets that are deposited in water or sediments. Do you know why you are supposed to eat large predatory fish like tuna infrequently? It is because of the bioaccu- mulation of mercury in those species. Some pollutants remain in an organism throughout its life, a phenomenon called bioaccumulation. In this process, an organism accumulates the entire amount of a toxic compound that it consumes over its lifetime. Not all substances bioaccumulate. Can you name one that does not? Aspirin does not bioaccumulate; if it did, a person would quickly accumulate a toxic amount in her body. Compounds that bioaccumulate are usually stored in the organisms fat. In the sediments, bacteria convert the droplets to the hazardous compound methyl mercury. Bacteria and plankton store all of the mercury from all of the seawater they ingest (Figure 1.2). A small fish that eats bacteria and plankton accumulates all of the mercury from all of the tiny creatures it eats over its lifetime. A big fish accumulates all of the mercury from all of the small fish it eats over its lifetime. For a tuna at the top of the food chain, thats a lot of mercury. Historic increases of mercury in the atmo- sphere: blue is volcanic eruptions; brown, purple, and pink are human-caused. The red region shows the effect of industrial- ization on atmospheric mercury. So tuna pose a health hazard to anything that eats them because their bodies are so high in mercury. This is why the government recommends limits on the amount of tuna that people eat. Limiting intake of large predatory fish is especially important for children and pregnant women. If the mercury just stayed in a persons fat, it would not be harmful, but that fat is used when a woman is pregnant or nursing a baby. A person will also get the mercury into her system when she (or he) burns the fat while losing weight. Methyl mercury poisoning can cause nervous system or brain damage, especially in infants and children. Children may experience brain damage or developmental delays. The phrase mad as a hatter was common when Lewis Carroll wrote his Alice in Wonderland stories. It was based on symptoms suffered by hatters who were exposed to mercury and experienced mercury poisoning while using the metal to make hats (Figure 1.3). Like mercury, other metals and VOCS can bioaccumulate, causing harm to animals and people high on the food chain. Mercury, a potent neurotoxin, has been flowing into the San Francisco Bay since the Gold Rush Era. It has settled in the bays mud and made its way up the food chain, endangering wildlife and making many fish unsafe to eat. Now a multi-billion-dollar plan aims to clean it up.

mercury poisoning can drive a person to be as mad as a hatter, which is based off of this novel.

The SP790 study (ClinicalTrials.gov, NCT00136045) showed benefits of rotigotine over placebo in improving symptom severity of restless legs syndrome (RLS), also known as Willis-Ekbom disease, on the International Restless Legs Syndrome Study Group rating scale (IRLS), Clinical Global Impression item 1 (CGI-1), RLS 6-item questionnaire (RLS-6), and the RLS-quality of life questionnaire (RLS-QoL) in patients with moderate to severe idiopathic RLS. To provide clinical context for the IRLS and to guide the choice of assessment scales for RLS studies, our post hoc analysis of SP790 data evaluated associations between the IRLS and the CGI-1, IRLS and RLS-6, and the IRLS and RLS-QoL. Scale associations were analyzed at baseline and at the end of maintenance (EoM) using data from the safety set (rotigotine and placebo groups combined [n=458]). Changes from baseline to EoM in IRLS score vs comparator scale scores also were analyzed. There was a trend towards increasing IRLS severity category with increasing CGI-1, RLS-6, and RLS-QoL score. Pearson product moment correlation coefficients showed correlations between IRLS and comparator scale scores at baseline and EoM as well as correlations for change from baseline to EoM. Correlations between the IRLS and comparator scales were substantial. These data indicate that the IRLS is clinically meaningful. The IRLS and CGI-1 are generally sufficient to evaluate the overall severity and impact of RLS symptoms in clinical trials.

The movie opens with credits and title over a black background. The setting is Guayjorm, Mexico. Inside an administration building is Susan Winter (Gloria Talbott). She is asking for permission from the Governor (Vincente Padula) to fly over a restricted area of his state--the Tarahumare Mountains. She explains that she has been planning three years to rescue her fiancee, Bruce Barton, whose airplane crashed in the area. The Governor asks about her colleagues and their reasons for helping. Despite her best efforts, the Governor is adamant--the answer is no. To make sure his orders are followed he tells her he will place a police escort on the plane. As their airplane is a four place model, this means someone must stay behind.Russ Bradford (James Craig) is at a magazine stand trying to buy a sports magazine. He doesn't speak Spanish and the salesgirl (Marlene Kloss) doesn't speak English. He joins the pilot, Lee Brand (Tom Drake) and Marty Melville (Lon Chaney, Jr.) at an outdoor table for lunch. They are waiting for Susan to return from her meeting with the Governor. Susan arrives and joins them at the table. They ask how things went. She responds, "I couldn't do a thing with the Governor." Lee doesn't think there will be any problems. He has a plan for the security escort. They drive out to the landing strip and are met by a policeman (Manuel Lopez). Lee gets in the airplane and starts the engine. It would appear that Marty will stay behind as Russ and Susan board the plane. Marty lures the policeman away from the plane, a Stinson Voyager, and then decks him and boards. The prop wash wakes the policeman and he fires at the departing airplane. The tower calls the plane and orders it to return to the field. Against orders, they continue their flight towards the restricted area of the Tarahumare Mountains. During the flight, Marty explains his reason for financing part of the trip, namely Uranium exploration. Marty brought a scintillator to locate his claim. When the scintillator tops out the airplane encounters turbulence. Lee announces that they are near the area where Bruce Barton was lost. Susan tells Lee to circle the area. Unfortunately, Marty is starting to panic and slugs the pilot. He tries to take over flying, but obviously doesn't know how. Russ tries to restrain Marty as Marty has the airplane in a steep dive. Lee comes to in time to take control and safely lands in a canyon with just enough room to stop. The four pile out of the plane. Lee sizes up the location and asks, "Well she's ok, but how are we going to get out of here?"Marty starts his search for Uranium. Russ cleans out his pipe and spots a huge lizard approaching. He calls to Lee and Susan to come, but by the time they walk over the creature is gone. He dismisses it as his imagination. Marty has found his Uranium. He claims it is a very rich deposit worth millions or even billions.That evening they sit by the fire. Susan locates their position on the chart and where Bruce crashed. Russ verifies it should only take a day to hike there. Marty announces that he will not join them. He's found what he came for. They are startled by a loud roar. The next morning Russ and Susan prepare for the hike. Marty tries to convince Lee to fly him out to file his claim. Russ and Susan begin their hike. She believes it is possible that Bruce is still alive, but even Russ thinks it is a long shot at best. He also is in love with Susan and proclaims same to her while they rest. They hear a loud squeak and spot an immense rat. An even larger Eagle attacks and kills the rodent. They run back to their encampment. They hear the engine start up and suspect they are about to be abandoned. Lee sees them and shuts down. Lee explains to Susan and Russ that he was just testing the motor. Susan demands the keys as Marty feigns surprise at this
