Symptoms typically include sensory impairment (vision, hearing, speech), disturbed sensation and a lack of coordination. The type and degree of symptoms exhibited depend upon the individual toxin, the dose, and the method and duration of exposure.
Common symptoms include peripheral neuropathy (presenting as paresthesia or itching, burning or pain), skin discoloration (pink cheeks, fingertips and toes), edema (swelling), and desquamation (dead skin peels off in layers).
Because mercury blocks the degradation pathway of catecholamines, epinephrine excess causes hyperhidrosis (profuse sweating), tachycardia (persistently faster-than-normal heart beat), mercurial ptyalism (hypersalivation) and hypertension (high blood pressure). Mercury is thought to inactivate S-adenosyl-methionine, which is necessary for catecholamine catabolism by catechol-o-methyl transferase.
Affected children may show red cheeks and nose, erythematous lips (red lips), loss of hair, teeth, and nails, transient rashes, hypotonia (muscle weakness), and photophobia. Other symptoms may include kidney disfunction (e.g. Fanconi syndrome) or neuropsychiatric symptoms (emotional lability, memory impairment, insomnia).
Thus, the clinical presentation may resemble pheochromocytoma or Kawasaki disease.
So exactly how much mercury a 45 lb. child would ingest by eating one 6 ounce can of tuna per week, and how does that compare to the EPA's reference dose? Take a look at the following calculations:
Step 1 - DETERMINE EPA's RECOMMENDED LEVEL FOR A 45 LB CHILD
* Multiply child's body weight by EPA's reference dose.
* Convert 45 pounds to kilograms = 20.45 kilograms
* 20.45 kilograms x .1 micrograms per kilogram per day
EPA RECOMMENDED LEVEL = 2.05 micrograms per day = 14.35 micrograms per week.
Step 2 - HOW MUCH MERCURY IS IN 6 OUNCES OF CHUNK WHITE TUNA?
* Multiply amount of fish by average mercury level for chunk white albacore.
* Convert 6 ounces to grams = 170 grams 170 grams X .31 ppm (or micrograms per gram)**
MERCURY INGESTED = 52.7 micrograms per gram
Step 3 – COMPARE MERCURY INGESTED WITH EPA'S RECOMMENDED LEVEL
* Divide 52.7 micrograms by 14.35 micrograms = 3.7
BY EATING 6 OUNCES OF CHUNK WHITE TUNA A WEEK, THE CHILD IS INGESTING ALMOST FOUR TIMES EPA'S RECOMMENDED DOSE.
In December 2003, the FDA began circulating a draft advisory warning women who are pregnant, nursing, or who might become pregnant about the dangers of mercury in seafood. Critics like the Environmental Working Group objected to the advisory's vague guidance on tuna, and subsequently filed a legal challenge, charging that the advisory did not meet standards for accurate government science established by the Data Quality Act.
In February 2004, a new analysis by the Environmental Protection Agency revealed that "about 630,000 children are born each year at risk for lowered intelligence and learning problems caused by exposure to high levels of mercury in the womb," nearly double the previous EPA estimate.

dilution is the solution.
How do you get rid of a supertoxic environmental waste like mercury...or even fluoride?
You pass it on to the consumer in everything they consume.
Mercury in lightbulbs is just another scheme to rid industry of their mercury wastes. That's it. Same thing with fluoride in the water...and now just about every food item available.
Its a screwed up world, and its only going to get worse. Enjoy life now while you still can

Most modern energy saving bulbs contain around 5 milligrams, which may not sound a lot at first. BUT it is going to drastically effect the Environment, and our way of life. it is inevitable. Many people will die. many animals will. die. vast areas will become no go zones without the proper PPE.
think about this, how many of these bulbs have you got in your home? 6? 7? 10?
How many houses are on your road? 30? now how many roads are in your village/town/city? lets say 150.
Now that's about 31,500 Light bulbs for an average, size town. THATS allot of bulbs. how much mercury is that?
well 31,500 bulbs times 5 milligrams =157.5 g of Mercury...

LED bulbs are the way to go, very low energy use and they last for many years.
