Lead is a highly toxic metal and a very strong poison. Lead poisoning is a serious and sometimes fatal condition. It occurs when lead builds up in the body. Lead is found in lead-based paints, including paint on the walls of old houses and toys.
For centuries, lead toxicity has been one of the most significant preventable causes of neurologic morbidity from an environmental toxin. A heavy metal, lead is ubiquitous in our environment but has no physiologic role in biological systems. Lead toxicity is a particularly insidious hazard with the potential of causing irreversible health effects. It interferes with a number of body functions primarily affecting the central nervous, hematopoietic, hepatic and renal system producing serious disorders.
X-Ray Fluorescence instrumentation was used to analyze lead, chlorine and bromine content in avgas liquids. The tests showed avgas contains the following:
- Lead: 48 ppm
- Bromine: 42.6 ppm
- Chlorine: 605.2 ppm
Bromine is a chemical element with symbol Br and atomic number 35. It is a halogen. The element was isolated independently by two chemists, Carl Jacob Löwig and Antoine JérômeBalard.
Chlorine is a chemical element with symbol Cl and atomic number 17. It has a relative atomic mass of about 35.5. Chlorine is in the halogen group and is the second lightest halogen, following fluorine.
How much lead is being “chemtrailed” across America due to aviation fuel?
Chemtrail conspiracy theory is an unproven suspicion that long-lasting trails, so-called “chemtrails”, are left in the sky by high-flying aircraft and that they consist of chemical or biological agents deliberately sprayed for sinister purposes undisclosed to the general public. Believers in the theory argue that normal contrails dissipate relatively quickly and that contrails that do not dissipate must contain additional substances.And though many consider the streaks beautiful against a bright blue sky, others are alarmed about them. Concerns range from the idea that these streaks could exacerbate global warming to more elaborate theories that the government has secretly been dumping harmful substances on the land.
At its most bizarre extreme, conspiracy theorists believe that the contrails which form behind jet aircraft are actually streams of toxic “mind-control” chemicals, which dilute before they reach the ground, leaving a gas we breathe in that keeps the general population in check.
But there are a growing number of chemtrail believers, who claim the conspiracy is actually a secret global plot to change Earth’s climate in the hope it will reverse the effects of climate change.
Small aircraft pilots dismiss the problem
The acknowledgement by the UN that our skies are being polluted with aluminium, barium, lead, arsenic, chromium, cadmium, selenium, and silver should give weight to the claims that Chemtrails cause a whole host of health problems in the general population.
Why are there overhead luggage compartments? It’s a test plane, and for FAA certification they have to demonstrate that everything works. That includes stuff like the emergency oxygen system, and more minor things like the luggage compartments. It’s a requirement that they don’t pop open in flight – so that needs to be tested. They are also handy for stowing the engineers’ stuff.
The Institute for Health Metrics and Evaluation (IHME) has estimated that in 2013 lead exposure accounted for 853 000 deaths due to long-term effects on health, with the highest burden in low and middle income countries. IHME also estimated that lead exposure accounted for 9.3% of the global burden of idiopathic intellectual disability, 4% of the global burden of ischaemic heart disease and 6.6% of the global burden of stroke.
Everyone deserves a healthy home environment, yet lead-based paints can still be found inside and outside of homes. Paint is the most common source of lead exposure, especially in homes built prior to 1978. One in four homes has lead-based paint, which puts children at increased risk when the lead paint starts to peel and chip. Lead from peeling or flaking paint is able to get into household dust, allowing us to breathe it in. This dust from lead-based paint can cover surfaces, like the counters, windowsills and floors, where children often play.
Other sources are waste incinerators, utilities, and lead-acid battery manufacturers. The highest air concentrations of lead are usually found near lead smelters. As a result of EPA’s regulatory efforts to remove lead from motor vehicle gasoline, levels of lead in the air decreased by 89 percent between 1980 and 2010.
On August 8, 2012, the commission adopted the Collin County Attainment Demonstration SIP Revision for the 2008 Lead NAAQS and the Agreed Order between Exide and the TCEQ. The SIP revision contains a reasonably available control measure and a reasonably available control technology analysis, demonstration of attainment through air dispersion modeling, a control strategy demonstration, an emissions inventory, a demonstration of reasonable further progress, and contingency measures. The Agreed Order makes the control strategies and contingency measures included in the Collin County Attainment Demonstration SIP Revision legally enforceable.
Lead was removed from automobile gasoline by the EPA
Lead colouring agents have been used for many years in auto enamels and lacquers. The highest levels of lead are found in the orange, red and yellow tones, where concentrations of more than 20% are common.
The pigments used in these highly coloured paints are based on lead sulphochromate and molybdate lead chromate. They are opaque and can be ground into fine particles, making them ideal for the high-gloss paints used on cars. They are also durable and resistant to ultra-violet light.
For older cars, the refinish industry can only provide accurate colour matches to vehicles that currently have paint containing lead on them by using the same lead-based pigments.
The researchers examined effects of childhood lead exposure on adult IQ by extending a long-term Boston study by another two decades.
They started with data collected from the initial 1980 study that included 249 infants who were followed and checked at 6, 12, 18, 24 and 57 months. At 10 years, 148 of the original participants were checked again. Blood lead levels were determined from blood samples in each of the follow-ups. Demographics, socioeconomic factors, lifestyle and medical history were collected through questionnnaires filled out by the children’s parents.
The NIH goes on to describe the harmful effects of lead:
Young children are particularly vulnerable to the toxic effects of lead and can suffer profound and permanent adverse health effects, particularly affecting the development of the brain and nervous system. Lead also causes long-term harm in adults, including increased risk of high blood pressure and kidney damage.
When will we decide to stop poisoning ourselves?
Symptoms of lead poisoning are varied. They may affect many parts of the body. Most of the time, lead poisoning builds up slowly. It follows repeated exposures to small quantities of lead.
Lead poisoning is diagnosed with a blood lead test. This test is performed on a standard blood sample.Lead is common in the environment. The National Institute of Environmental Health Sciences reports that no amount of lead in the blood is safe. It is known that levels as low as 5 micrograms per deciliter can be associated with health problems in children.
Lead causes damage to the kidneys, liver, brain and nerves, and other organs. Exposure to lead may also lead to osteoporosis (brittle bone disease) and reproductive disorders.
Excessive exposure to lead causes seizures, mental retardation, behavioral disorders, memory problems, and mood changes. Low levels of lead damage the brain and nerves in fetuses and young children, resulting in learning deficits and lowered IQ.
Other ways lead can enter the environment are through mining practices, steel industry, crop enhancers, improperly disposed of batteries, or improperly stored metal parts such as machinery that can break and leave pieces or shavings which may leech into the environment.
