Facts
Robert Joiner worked as a electrician in the department of Water and Light in Thomasville, Georgia since 1973. In various article it is claimeds that their is no actual proof of Joiner being expoesed to PCB's, we do know what a tyoucal day looked for him. His day was usually fixing the city's transformers, doing that involved him having his arms and hands in the fluid, sometimes that fluid would get in his eyes and mouth. Another study that joiner brought up to court was one stating that the incidence of of lung cancer deaths among similar workers had been higher than expected.

Smoking or PCB's
Joiner was a smoker, smoking could of influenced his likelyhood of getting a cancer cell but his claim is that was because of PCB. PCB's(Polychlorinated biphenyls) has many affect on the human body and other animals on which it has been tested on. Some of the symptoms you would develop after being exposed is irritation of the nose, lung, skin and eye problems. One of the study that was taken place used mice that wre injected with PCB's. The results showed that PCB's did cause canc er cells but, not the one that was found in joiners body. The mice from the study developed a alveologenic adenomas, joiner developed a small carcinomas cell. In anthor article that ran a similar study, nine of the twwelve developed tumors as the amount of of PCB was ingested. This doesn't mean that smoking cause, the reason is because humans that have been exposed to PCB's is a very small number, most people that do get it have been exposed to ther chemicacl or have a medical condition.

Smoking can cause almost anywhere in the body, cancer is a disease in which abnormal cells multiply rapidly out of control which later invade other tissues. . Carcinoma was the type of cancer cell that was developed in joiner, that type of cancer starts in a cell that makes up the skin or the tissue lining organs (Liver or Kidney). Symptoms include a red nodule, flat sore with a scaly crust, a new sore or raised area on a scar or ulcer.

Daubert Standard
When reviewing this court case we keep in mind the parts of the Daubert standard. Robert Joiners theory can be tested and was tested, we don't know if it was subjected to peer review. We don't know the error rate since there wasn't a direct relationship, maintenance of standards controlling its operation is unclear and we also don't if it attracted a part of the scientific community.
