Saliva is composed of 99% water and 1% electrolytes and enzymes There are three pairs: parotid, sublingual, and submandibular Remember, these fun facts aren't just fun-they're facts. So the next time someone says you're being lazy, fire back with “My eye muscles are working out more than you do any day at the gym.” In your lifetime, you will produce enough to fill almost three 16 ft (5 m) swimming pools. You produce 0.4 gallons (1.5 liters) of saliva every day. Hungry for one more? Good! Besides being the start of the digestion process, your saliva also prevents tooth decay and stops the tissues of your throat from desiccating. Forget running on a treadmill-that's what I call a workout!Īny tennis players reading this? Take a deep breath, because this might shock you: your lungs may seem small in your chest, but their combined surface area is a whopping 70 m²! That's the size of a singles tennis court! Your body is constantly in motion thanks to your muscles, but your extraocular muscles are the busiest skeletal muscles you have! They move over 100,000 times a day. I can't even come up with an comparison for that kind of storage! Some people refer to the brain as the body's computer, and they're not too far off the mark! In terms of memory storage, your brain holds approximately 256 exabytes. Your heart is known for pumping blood through your body at an incredible rate, but did you know that your kidneys process over 50 gallons (189.2 liters) of blood every day? That's nearly double the amount the heart receives each day. In fact, your body is so cool that I decided to dedicate a post to some of its most amazing aspects. Antimony is considered to be one of the most toxic of the heavy metals, and therefore has lower limits than other metals except cadmium (Cd) and mercury (Hg).Did you know there isn't a moment that your body isn't doing something cool? It's true! Your body is a well-oiled machine that works to keep you going each day. Is antimony a heavy metal?ĪNZECC drinking water and sediment limits for some “heavy metals”. Antimony oxide is an antimony compound that is added to textiles and plastics to prevent them from catching fire. What products contain antimony?Īntimony ores are mined and then mixed with other metals to form antimony alloys, which are used in lead storage batteries, solder, sheet and pipe metal, bearings, castings, and pewter. Generally speaking, the main end-of-life recycling option is from spent lead-acid batteries, where antimony is directly recovered as a lead-antimony alloy. China currently controls 92% of the world supply of antimony products. Government considers it to be critical and strategic due its military applications. This includes things like copper, aluminum and iron, but also less well-known materials, like the “rare earth elements”, what the Japanese refer to as “the seeds of technology”.Īlthough antimony is not a rare earth, the U.S. Metals are considered non-renewable due to their nature. If we continue to use certain materials, including metals, without finding a way to replenish them, then those materials will run out. Non-renewable resources are natural materials that can’t be replenished at the same rate they’re consumed. The world will run out of minable gold, though exactly when is unknown. While there is no way to know exactly how much gold remains to be mined, experts agree that there are few remaining, untouched gold deposits. Will we run out of gold?īecause of this, the amount of gold on earth is finite. It is mined in China, Bolivia, South Africa and Mexico. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Antimony is sometimes found in pure form.
