Aluminium Water is it ok to use aluminium water cans?
Aluminium is soft metal - so it does dispens in the content expecily it is acrid or acidic in nature the oxydation is faster - when u clean ie wash the vessel u can see how fast - it errode when u eat or drink the content - contaned in and aluminium vessel sure - u also get a good amount of alumin in ur food and drink - - it has long term and short term effect in body

Aluminum causes an oxidative stress within brain tissue. Since the elimination half life of aluminum from the human brain is 7 years, this can result in cumulative damage via the element's interference with neurofilament axonal transport and neurofilament assembly. Some experts feel it plays a role in leading to the formation of Alzheimerlike neurofibrillary tangles.
Aluminum also has a direct effect on hematopoiesis. Excess aluminum has been shown to induce microcytic anemia. Daily injections of aluminum into rabbits produced severe anemia within 2-3 weeks. The findings were very similar to those found in patients suffering from lead poisoning.
Aluminum may cause anemia through decreased heme synthesis, decreased globulin synthesis, and increased hemolysis. Aluminum may also have a direct effect on iron metabolism: it influences absorption of iron via the intestine, it hinders iron's transport in the serum, and it displaces iron's binding to transferrin. Patients with anemia from aluminum toxicity often have increased reticulocyte counts, decreased mean corpuscular volume, and mean corpuscular hemoglobin.
Physics help : Question about water heated in an aluminium saucepan?
a) Describe how heat energy is transferred from the flames to the surface of the water in the saucepan.
b) Explain why the handle is made of plastic rather than aluminium
c) Describe how heat is lost by convection from the surface of the water.
a) energy is transported through convection, conduction, and radiation The flame is produced from a chemical reaction. Energy is released from this reaction as kinetic energy and radiation. Kinetic energy is the energy of motion. Things that are moving faster (on the molecular level) are hotter. So the particles leaving the reaction are moving faster (on average) than when they entered. radiation means electromagnetic waves the flames you see are electromagnetic radiation so when those waves hit the pan the pan gains energy. convection is the transfer of heat through moving particles. Air gets heated by the transfer of kinetic energy from the fast moving particles leaving the reaction. This warm air then flows up to the pan and heats it. Conduction transfers heat from particles to adjacent particles. So when the warm air from convection reaches the pan conduction happens. Then in the pan itself heat is transfered from the bottom to the top and then to the water through conduction.
b) The pan gets quite hot when you heat it. I'm sure you have brought your hand close to a hot pan before and chose not to touch it or touched it and regretted it. If you touch the handle of the pan it never seems as hot. That is because plastic does not conduct heat nearly as well as aluminum. So conduction makes the pan and water warm, but the hot pan has trouble transfers heat to the handle so it heats up much slower. Of course, after some time this would mean the plastic is too warm to touch as well, but unless the pan is very hot the plastic will lose the added energy through radiation fast enough to keep the handle cool. (This radiation is just like the radiation you see from the flame but not as hot.)
c) Heat is lost from the pan and water just like it is gained so this is just like what I wrote above except the water is transferring energy to the colder air above.
note: heat is transferred between from hot things to cold things and cold things to hot things, but because the hot things have more energy they transfer more until everything is at an equal temperature (temperature is the measure of kinetic energy (at the molecular level). That is why the cooler pan and water heat up from the flame. This is also why the water heats up the air above it.
One way to think of this concept is: two people have marble Jim has 5 Jill has 50. They run into each other and their piles are mixed. They both grab for the marbles Jim grabs 20 Jill grabs 35. They did not grab equal amounts because most of the marbles were closer to Jill because she started with most of them. Eventually they end up sharing equally. To use this same thing to describe of the plastic heats up slower. Jim is plastic and has 5 marbles. Jill is aluminum and has 50 and Ben is water and has 5. Jill and Ben hit there marbles are mixed Jill grabs 40 and Ben 15. When Jill and Jim hit, Jim who holds on to his marbles more tightly does not drop as many but also cannot pick up as many because he is busy tightly holding his marbles. So Jill can grab more of her marbles since Jim is slow to grab new ones.
Hope this helps the explanation with Jim and Jill is a little weird but it kind of works.

Great post, Boo. I have come to the conclusion, from the experience here in the office, that it's sheer laziness that keeps people pulling a bottle rather than taking a moment to fill one. We have clean glasses, filtered cold water and filtered water-made ice… and still the guys pull out a cold bottle of water, rather than take a moment (literally a moment) to fill a glass, or an aluminium water bottle. The average American will say, it doesn't matter. The earth is going to hell in a handbasket anyway, so me and my “footprint” is small in the scheme of things. It amazes me that those same people feel so “large” when they want something; their personal signifigance is based only on what they choose to find important.
I applaud you and the steps you take to leave a world for our future generations. We used to look forward to leaving a “Better” world behind us… now we have to look at, will we leave a recognizable world behind at al.
