science behind superstition .part 2-why is bamboo burning prohibited in *Snatan Dharma* ?

as i mentioned in my first post Science behind superstition regarding worship of peepal(FICUS RELIGIOSA) in india and prohibited to cutdown .
as in snatan dharma and shastra burning of bamboo is prohibited .it is also prohibited in HAWAN,agarbatti,cooking food and in cremation(sanskaar).this prohibition was not on theoretically,rather on deep scientific research, done by indian scientist(rishimuni) thousand years ago and modern science proved it in 21st centuary.
the scientific reason is that bamboo have Lead(Pb) and heavy metals which on burning produce lead(II) oxide(PbO) and heavy metal oxide.

2PbO2→2PbO+O2
Lead oxide is toxic if swallowed or inhaled. It causes irritation to eyes, skin and respiratory tract. It affects central nervous system, kidneys, blood, and reproductive system. lead oxide is neurotoxic as explained in a paper 2009.
Biological monitoring techniques are useful for risk assessment of toxic agents in the field of environmental health. Lead, a systemic toxicant affecting virtually every organ system, primarily affects the central nervous system, particularly the developing brain. Consequently, children are at a greater risk than adults of suffering from the neurotoxic effects of lead. The ability of lead to pass through the blood-brain barrier is due in large part to its ability to substitute for calcium ions. Within the brain, lead-induced damage in the prefrontal cerebral cortex, hippocampus, and cerebellum can lead to a variety of neurological disorders, such as brain damage, mental retardation, behavioral problems, nerve damage, and possibly Alzheimer’s disease, Parkinson’s disease, and schizophrenia. At the molecular level, lead interferes with the regulatory action of calcium on cell functions and disrupts many intracellular biological activities. Experimental studies have also shown that lead exposure may have genotoxic effects, especially in the brain, bone marrow, liver, and lung cells. This paper presents an overview of biomarkers of lead exposure and discusses the neurotoxic effects of lead with regard to children, adults, and experimental animals, updated to January 2009.

conclusion-as in sashtra ,allow and prohibition was scientific basisrather than on theoretically basis
