- 1. Lead Chromate
- [A yellow, orange or red colored, crystalline, inorganic compound that emits toxic chromium fumes upon heating. Lead chromate is highly corrosive and is a strong oxidizing agent. This substance is used in printing inks, paints and to color vinyl, rubber and paper. Lead chromate primarily affects the lungs causing shortness of breath, bronchitis, pneumonia and asthma but can also affect the gastrointestinal tract, liver, kidneys and immune system. This substance is a known human carcinogen and is associated with an increased risk of developing lung cancer and cancer of the sinonasal cavity.

| - 10. learned helplessness
- [exposure to adverse and uncontrollable events often causes the reaction of helplessness; symptoms include: difficulty in learning behavior patterns in reaction to controllable adversities, reduced motivation in initiating coping responses, and emotional reactions of sadness or depression.

- 2. Lead Compound
- [An inorganic or organic substance that contains the metallic element lead either in its positive-2 or 4 valence state. Lead compounds have a wide variety of applications in industry. Exposure to lead compounds affects the lungs, central nervous system and kidneys. Lead compounds are possible mutagens and are reasonably anticipated to be human carcinogens. The substance may be associated with an increased risk of developing lung and stomach cancer. (NCI05) ( NCI )] (UMLS (NCI) C0303231) =Chemical Viewed Structurally
