Alchemists found a successful formula to turn
lead into gold.
Adults today grew up at a time when we were still putting several hundred thousand tons of
lead into gasoline each year.
Smoking any type of tobacco products on the range should be prohibited to prevent acceleration of inhaled
lead into the blood stream and ingestion of lead transferred from hands to the cigarette, cigar, etc.
The city also added calcium orthophosphate to the water supply to control corrosion in pipes which leaches
lead into drinking water and recommended running taps for one minute before using.
Metallic alloys such as brass and bronze often contain lead, so brass faucets or plumbing fittings may also release
lead into home water systems.
Other studies have shown that the intrusion of
lead into the lens of the eye may cause protein conformational changes that decrease lens transparency.
They found that women who never had children -- and therefore never shed significant bone and bone-bound lead to developing offspring -- carry far more
lead into old age than those who had been pregnant.
the skeleton), is to maximize the lead concentration gradient between these tissues and blood for prolonged periods of time, thereby favoring continued efflux of
lead into the circulation and elimination via urinary of fecal routes.
Lead solder, flux and piping have also been banned by EPA because these plumbing materials can release traces of
lead into the water.
Times of physiologic stress such as menopause can result in the release of stored
lead into the blood through demineralization, the same process that causes calcium to be released from bone.
16) suggested that disintegration caused by mechanical joint action leads to an increased release of
lead into synovial fluid.
Conversely, trabecular bone has a relatively rapid turnover and releases a good deal of
lead into the blood.
Storm water can sweep this
lead into nearby culverts and arroyos, and ultimately washes it into nearby waterways where it can adversely affect water quality and aquatic ecosystems.
Some candles made with metal wicks emit
lead into the air when burned, finds a study by environmental chemist Jerome Nriagu of the University of Michigan in Ann Arbor, scheduled for publication in an upcoming issue of Science of the Total Environment.
