It appears that most of us believe that the amount of lead weights fishermen have lost to snaggy bottoms, say for the past 50 years, has not significantly increased the ppm of lead in sea water therefore seafood, ultimately our brains.
*I'm talking about tons of lead fishing weights being grinded down with each wave on sea shores along thousands of miles of the world's great fishing spots.
"In 1919 the spent lead pellets from waterfowl hunting was positively identified as a major source of deaths of bottom-feeding waterfowl." In 1991, 72 years later, the United States Fish and Wildlife Service banned lead shot in migratory waterfowl hunting. The point being, it took brilliant scientists 72 years to effectively communicate a health-significant truth,
Why did it take 72 years, but only for lead buckshot? What most don't know is that there is a difference between saying, telling, putting out, announcing, publishing, lecturing, and, communication. When communication takes place the subject is gotten it's recreated. Few scientists attend leadership-relationship communication workshops after they get their degree(s). Most sincerely believe that what they learned about communication is what it is.
For decades researchers have been measuring the lead in fish, crustaceans and the frequent sea mammal beachings; we assume that dangerous findings would be front page news. However, few researchers spend as much time studying both their specialty and their leadership-communication skills, ergo, they have yet to learn how to share significant truths/findings effectively. It's not that they haven't shared their findings, they
have been for 72+ years, just ineffectively.
Hunters eventually opted for lead-free shotgun pellets.
Perhaps in a century lead will be as valuable as gold and weekend miners will farm the sea shores.

* Per
Lenntech "Seawater contains trace amounts of lead (2-30 ppt). On average rivers contain between 3 and 30 ppb. Phytoplankton contains approximately 5-10 ppm lead (dry mass), freshwater fish approximately 0.5-1000 ppb, and oyster approximately 500 ppb.
The World Health Organization (WHO) stated a legal limit of 50 ppb for lead in 1995, which is decreased to 10 ppb in 2010."
