Are you raciest or something? Just because something came from Asia does not mean that it is infiltrated with lead, msg, or radioactive elements! When will you people learn?!
Actually seeing as how there was a rise in this issue a few years ago, this is a valid question. To answer it, there is new regulations on jewelry where those chemical components are prohibited within sales in most areas while in others it must be under a certain percentage (within safety regulation). Any jewelry with traces of lead is not allowed to be sold to children or pregnant women and must have a warning. Always ask the seller questions before buying though. Oh and not all "Tibetan Silver" sellers are Asian (for whomever answered above me).

How does arsenic from cigarettes effect the body?
Humans ingest an average of 50 milligrams of Arsenic a day, 80% of this comes from Meat, Fish, Poultry and Crop grown products; the other 20% comes from drinking water. Cigarettes contain approximately 0.8 micrograms of arsenic per pack (0.04 micrograms per cigarette). Two basic forms of arsenic exist; organic and inorganic. Inorganic arsenic is more poisonous than organic, and is present in cigarettes, drinking water and crops grown in the USA. The same amount of arsenic is present in crops as is in cigarettes. The reason behind this is that farmers used arsenic for pesticides, and the soil still contains this compound which is then filtered into drinking water supplies or into the plants themselves. Tobacco itself does not contain arsenic, it is a left over from pesticides still present in the soil. The full answer to your question (once you understand how it got there) is; Arsenic in tobacco effects you the same way as the arsenic in corn, too much will kill you (corn or tobacco).

Does tobacco contain arsenic?
In minute quantities (approx.10-30 micrograms/kg in tobacco smoke), far too small to do any -- noticeable harm when compared to the other ingredients. And far too little to do any noticeable harm when compared to the levels of arsenic in the food we eat, the water we drink and the 'fresh air' breathe. The smoke from one cigarette MAY contain UP TO 30 nanograms (billionths of a gram) of arsenic. The maximum level of arsenic allowed in drinking water is 10 parts per billion. So half a litre of water (500grams) may contain 5,000 nanograms of arsenic, equivalent to that from over 150 cigarettes or more, and still be considered 'safe'. The maximum level of arsenic in food, such as bacon and eggs, is 500 parts per billion. A 'safe' egg weighing approximately 60 grams may contain up to 30,000 nanograms of arsenic - 1,000 cigarettes-worth. P.S. Historically, some tobacco may have contained signficantly greater concentrations of arsenic. (Tobacco Control are not particular concerning the source of their 'facts'.) The insecticide lead arsenate was widely used, not only on tobacco but also on other crops, such as apples and cranberries. Its use was banned in the 1980s.

Use the foodchain to suggest how copper and arsenic get into the body of a sparrowhawk?
The earthworm would take in the copper and arsenic from the soil. The blackbird would eat it then the sparrowhawk would eat the blackbird. This may result with the sparrowhawk still having the copper and arsenic inside it. :)
What are the chemicals used in extraction of silver from x-rays?
X-rays are a form radiation, and you can't extract silver from that. But X-ray plates or slides, for those places that still use wet processing, do contain silver which can be extracted. Don't know how though.

What is rat poison called in cigarettes?
This is historical stuff. Decades ago, arsenic was used as a rat poison and also as a pesticide on tobacco and many other plants. Traces of pesticide remained on the plants and that's how it entered both the food-chain and tobacco. Although its use has been banned, traces of arsenic are absorbed by ALL plants from the environment. Drinking water contains arsenic from the same source. Government agencies set safe levels for it in drinking water. A tumbler of drinking water can contain the same amount of arsenic as hundreds of cigarettes and still be considered "safe". "Healthy" oily fish and cereals contain the more modern rat poison, Vitamin D3. Another widely used rat poison is one of the most prescribed drugs, Warfarin.
