16. Cultural environmental hazards Cultural (lifestyle) hazards: result from the place we live, our socioeconomic status, our occupation, our behavioral choices –Smoking, drug use, diet and nutrition, crime, mode of transportation

17. There are over 4,000 chemicals found in tobacco smoke and over 400 toxins. There are over 60 carcinogens proven to cause cancer in humans. Causes 1 in 5 deaths in U.S. Leading cause of cancer deaths Tobacco

18. Smoking Obesity (2010) - 22.7% HI (5 th lowest) Diabetes - 28.5 million U.S. (8.7%) - 100,000 in HI (8.3%) Hawaii Stats HI %US % White12.717.4 BlackNSD19.1 HispanicNSD14.1 Asian/Pacific Islander 10.28.1 American Indian/Native Alaskan NSD32.8 Other21.121.2 % of Adults who smoke by race/ethnicity 2010

19. Infectious diseases kill millions Infectious diseases kill 15 million people per year. –Half of all deaths in developing countries –Developed countries have better hygiene, access to medicine, and money. Vector: an organism that transfers pathogens to a host

20. Biological hazards Result from ecological interactions –Viruses, bacteria, and other pathogens –Infectious (communicable, or transmissible) disease E. coli HIV TB Malaria

21. Dengue fever Apr 2011 4 confirmed cases Leptospirosis

22. Environmental health hazards exist indoors Radon: a highly toxic, colorless, undetectable radioactive gas –Builds up in basements –Can cause lung cancer Lead poisoning: from lead pipes, paint –Damages organs, learning problems, behavior abnormalities, death Asbestos: insulates against heat, cold, sounds, and fire –Asbestosis: scarred lungs don’t function –Also causes a type of lung cancer Asbestos removal can also be dangerous Not a problem in Hawaii problem in Hawaii (<1978) Renovation issues

23. Endocrine Disruptors Lake Apopka alligators In 1985, alligators had bizarre reproductive problems –Non-viable eggs, depressed or elevated hormone levels The lake had high levels of agricultural chemicals and fertilizers that were disrupting the endocrine systems of alligators during development in the egg.

24. Evidence for hormone disruption Frogs also have gonadal abnormalities. –Male frogs exposed to very low levels of atrazine became feminized. –Levels were below EPA standards for human health. Tyrone Hayes U.C. Berkley

26. PCBs DDT Bioaccumulation biomagnification Pesticides, Herbicides & other organochlorines

27. Common pesticides

28. Biomagnification Toxicants can accumulate and biomagnify

29. Heavy metals resist biodegredation Natural occurrence- volcanoes Mercury (Hg) Copper (Cu) Lead (Pb) Cadmium (Cd) Toxic Metals

31. Minamata Disease (1953-1960)– Japan Industrial pollution from plastic plant; dumped mercuric chloride into bay Ingestion of Hg tainted shellfish  43 dead and 700 permanently disabled Heavy Metals

32. Cu: Tributyl tin (antifouling paint for boats) Banned in U.S. 1980s Acts as an immunosuppressor Accumulations unusually high in small whales May be associated with strandings Toxic chemicals

33. Pb: Leaded gasoline invented 1920’s Enters water from automobile exhaust, runoff and atmospheric fallout of industrial waste and landfills, mines, dumps Leaded gas banned in US in 1980’s has reduced pollution in ocean Bioaccumulation  biomagnification Toxic chemicals

34. Inquiry 1.What is an endocrine disruptor? 2.What effect does lead have on the body? 3.What is bioaccumulation and biomagnification? 4.What is an HAB and what is it caused by? 5.Distinguish between point source and nonpoint source pollution? 6.How is leptospirosis transmitted? 7.What heavy metal was involved with the Minamata disease?
