How much should be the VOC in materials:
Let us see what the Indore Environmental Quality says about VOC:
Lead is a naturally occurring metal found deep within the ground. It occurs in small amounts in ore, along with other elements such as silver, zinc or copper. Even though it's found in small amounts, there is an abundant supply of lead throughout the earth. Because it is widespread, easy to extract and easy to work with, lead has been used in a wide variety of products including:
Paint
Ceramics
Pipes
Solders
Gasoline
Batteries
Cosmetics
However, the most common sources of lead exposure in the United States are:
Lead-based paint in older homes
Contaminated soil
Household dust
Drinking water
Lead crystal
Lead-glazed pottery
Some of the health effects associated with lead exposure: The 2012 National Toxicology Program (NTP) literature-based monograph on health effects of low-level lead provides this information on health effects: Health Effects of Low-Level Lead.
Testing of VOLATILE ORGANIC COMPOUND:

| Blood Lead Level | Health Effects |
|---|---|
| Blood lead levels below 5µg/dL |
Children: Decreased academic achievement, decreased IQ, and decreases in specific cognitive measures, increased incidence of attention-related behaviors and problem behaviors
Adults: Decreased kidney function, maternal blood lead associated with reduced fetal growth
|
| Blood lead levels below 10µg/dL |
Children: Delayed puberty, reduced postnatal growth, decreased IQ and decreased hearing
Adults: Increased blood pressure, increased risk of hypertension, and increased incidence of essential tremor
