3. Activity: Unhealthy home may include: Biological Physical Chemical hazardous Give 4 examples for each

4. 1- Biological hazardous:Dust mites • Dust mites are tiny, invisible bugs that are the biggest cause of indoor allergies. • They irritate the eyes and nose and cause asthma attacks • Dust mites live in warm, humid places filled with dust such as bed pillows, mattresses, carpets, stuffed toys, clothing, and furniture.

6. The protein substances in the dust mite feces produces antibodies in humans who are allergic when these are inhaled or touch the skin. These antibodies cause the release of histamines which causes to nasal congestion, swelling and irritation of the upper respiratory passages

7. typical symptoms of an allergy to dust mites: • Itchy, red or watery eyes • Runny nose, • Sneezing, • Asthma, difficulty in breathing, • Infantile eczema • Itchy nose • Frequent awakening • Swollen, blue-colored skin under eyes

8. They feed on the tiny flakes of human skin that shed from our bodies each day

9.

11. 2- Mold • Mold is a kind of fungus, a simple plant that grows on soil and other plants. • In the home, it grows on walls, clothing, old or spoiled foods • look like black or yellow powder, tiny threads, or white and blue fuzz

12. Molds cause breathing problems, headaches, skin irritation, and can trigger asthma attacks and allergic reactions. • To prevent and get rid of mold: • Fix leaks in walls, roofs, and pipes. • Improve ventilation. When more air passes through the home, it keeps everything drier and helps prevent mold from growing. • Wash areas where molds grow with bleach solution.

17. Scenario #1 • A mother tells you that she arrived home last Wednesday to discover that the lawn care company had sprayed. There was a strong odor, and liquid could be seen on the grass and furniture. After playing outdoors that afternoon, her child developed nausea and vomiting, with some sweating but no fever. She also had mild tremors. Her pediatrician diagnosed her child with “flu” (GI virus). However, she is asking you if you think the pesticides may have had something to do with her child’s illness.

18. Do you think that pesticide poisoning (or poisoning by other environmental toxicants) could be misdiagnosed? • If the child in this scenario did develop illness from the pesticides, why didn’t her mother get sick?

19. Principles and Concepts • Environmental health effects may mimic other conditions • Children’s behavior may increase susceptibility to environmental toxicants.

20. Pest control without chemicals • For cockroaches, mix boric acid with water to make a thick paste. Add corn flour and make little balls. Leave them around the house, • For ants, sprinkle red chili powder, dried peppermint, or crushed cinnamon where they enter. • For flies, soak crushed basil leaves in water for 24 hours. Filter and spray onto flies.
