Hypothesis
If lead is introduced into the human body, then it will be detrimental and possibly fatal to those with the poisoning.

Background Information
• Lead is an element, so it cannot be transformed into any other material.
• Lead’s melting point is 327 C.• Lead’s specific gravity is 11.35 grams per a cubic
centimeter.• A substance with 50 ppm in soil or solid waste qualifies
the substance as a hazardous waste.• Lead is a heavy metal and therefore it is extremely toxic.• Short term exposure to major amounts of lead can make
you seriously ill.

Background Information(cont.)
• Most of the lead in the human environment is from lead paint and gasoline.
• The maximum amount of lead allowed in drinking water is 0.05 mg/liter.
• Lead can be found in leaded paint, drinking water, from lead pipes and solder, batteries, hair dyes, lead weights, incinerated products such as printing inks and paper, and leaded gasoline.

Conclusion
In conclusion, it was found out that lead can make a person seriously ill if they are in contact with large amounts of it for a short period of time. It was also discovered that if a person is in contact with large amounts of lead for a long period of time, it can impair their neurological development, damage to your brain and/or nervous system, or create kidney disease in the person.

Recommendations
• The next time lead poisoning is being tested in children, the blood of the parents of each child should be tested for lead poisoning.
• The blood level of other playgroups should have also been tested for lead poisoning so that the two playgroups can be compared.
