  4. 4. Triage inquiries related to exposure to environmental contaminants at Superfund and other hazardous waste sites Evaluate potential human exposure to environmental contaminants Evaluate suspected elevations in diseases thought to be related to the environment 4 Medford Public Housing: Lead in Soil Community Assessment Program
  5. 5. Cancer Facts & Figures According to the American Cancer Society, 1 in 3 women and 1 in 2 men will be diagnosed with cancer at some point in their lifetime Over the past 40 years, the dramatic rise in the number of cancer cases reflects in part the increase in the population, particularly in older age groups, and improved diagnostic capabilities to identify cancers at earlier stages 5
  6. 6. Cancer Risk Factors Examples of different types of risk factors include:  Personal risk factors such as smoking, lack of crude fiber in the diet, high fat consumption, alcohol abuse, and reproductive history have been linked to the development of some cancers.  Heredity and family history are important risk factors for several cancers  Occupational exposures (such as inhalation of asbestos fibers) and environmental contamination have been associated with some types of cancer 6
  7. 7. Cancer Clusters A large number of cases of one type of cancer diagnosed in a relatively short period of time rather than several different types diagnosed over a long period of time A rare type of cancer rather than a common type An increased number of cases of a certain type of cancer in an age group not usually affected by that type of cancer 7

  9. 9. Investigative Approach Step-wise Process:  Phase I – preliminary review (often handled with a phone call)  Phase II – descriptive study (letter or report)  Phase III – analytical study (e.g., Woburn childhood leukemia study) 9
  10. 10. Links to Massachusetts Cancer Registry database allow for: Risk factor analysis Determining if age, gender, histology, or tobacco history patterns differ from what would be expected Looking at date of diagnosis to assess temporal clustering Looking at residence at diagnosis to assess spatial distribution (using population density overlays) 10

  12. 12. Sources of Environmental Contaminants Point of Chemical Release (e.g., leak or spill) Environmental Pathways  Air  Water  Soil  Food 12
  13. 13. Exposure occurs when a chemical enters the body through:  Inhalation  Ingestion  Drinking water  Food sources (e.g. fish)  Inadvertent ingestion (e.g. soil)  Dermal contact No exposure = No health risk How Chemical Exposures Happen 13
  14. 14. Exposure Assessment Methods Exposure Assessment – evaluation of available environmental data and human behavior information to estimate external dose exposure (air, water, soil, food). Biomonitoring – analysis of biological samples (e.g., urine, blood serum) to assess internal dose exposure to a specific contaminant 14

  16. 16. Historical Operations Main Plating Room circa 2005Main Plating Room circa 1944 • Operated from 1940 - 2007 • Industrial plating facility, specializing in chrome plating very large objects (e.g., pistons for large hydraulic equipment, rollers for paper mills) 16

  23. 23. Massachusetts Environmental Public Health Tracking Portal  Make tables, charts, and maps of health and environmental data for communities.  Provides information on datasets www.mass.govdphmatracking 23
  24. 24. Reducing Exposure to Environmental Chemicals Examples of Common Sense Steps: Wash hands often, particularly before eating and after gardening Wash fruits and vegetables before consumption Read labels and follow directions when using household chemicals (e.g., pesticides, cleaning products) Keep home well ventilated Be aware of environmental concerns in your community Avoid cigarette smoke Follow fish consumption advisories If use a private well for drinking water, have it tested Have home tested for radon 24
