Lead Exposure: Steps to Protect Your Family

Lead is
Lead (Pb) is an element found in Pb ore deposits that are broadly spread throughout on the planet.

Some history
In the U.S. environment, a source of Pb has historically been - air emissions from the combustion of leaded gasoline, which was decommissioned after 1973 and later banned in 1995.

The shedding of lead-based paints from weathered surfaces (highly concentrated lead shavings and dust) in older buildings (before the Pb was banned in 1978) remains a source of childhood lead poisoning in the US.

Despite the ban on the use, years before the ban left a bright lead deposit on the present life of American society.
Lead powder, one of the chemical forms
Lead (Pb) does and does not:
Pb does not decompose in the environment although it can exist in multiple chemical forms.
Particulate matter (PM) contaminated with Pb can spread through the air, water, and soil. Precipitation is the main source of Pb found in soils that are not affected by other sources (for example, dust from deteriorating lead-based paint).
Pb is strongly adsorbed on most soils, which limits the leaching rate. A high chloride content (if we talk about nature and soil) is the main requirement that develops lead mobility.
Pb is continuously transferred between air, water and soil by natural chemical and physical processes as weathering, runoff, precipitation, dry dust deposition, and stream flow; however, soil and sediment appear to be important lead sinks.
We are exposed to lead every day. It's in the air we breathe, in the products we buy (we don't know what soil or pesticides been used to grow these veggies), in the tap water we drink (even if it was boiled), in the soil that we bring into the house on the soles, and dust that settles on everything.
Lead sources
Lead can be found in rechargeable batteries, ceramic glaze (that utensil with a gold edging that cannot be used in the microwave), cosmetics, hair dyes, jewellery, fishing tackle, imported children's toys from Asia, candy and food packaging.

For all-over 16 years of age, exposure to lead above normal is associated with professional activities: working in the field of high metal contact or living in an area where many factories and industries are located.

For children, the main source of exposure to lead is dust carrying lead collected from various sources, such as shavings of old lead-based paint.

"Natural Pb", because of the higher activity due to age, has a strong effect on children. Kids, unlike adults, acknowledge the world around them, touching everything with their hands and immediately pulling hands to their faces. That is when metals accumulated within dust particles and soil leads get closer to the respiratory system, receiving "a ticket" to the developing body of the child.
How to prevent or escape lead poisoning
Keep your home clean and dust-free
Get rid of household dust from deteriorating lead-based paint or contaminated soil
Mist areas before sanding, scraping, dusting and cutting to
keep the dust down (except within 1 foot of live electrical outlets).

Let the water run to flush the tap, for coking use only cold water
Use a water filter
