Reducing Health Risks Related to Environmental Lead Exposure

  • Date: Jan 01 1989
  • Policy Number: 8909

Key Words: Occupational Health And Safety

The American Public Health Association,

Recognizing that exposure to lead is universal as a result of human-caused disturbances in the natural distribution of lead, and that elevation in the body burden of lead is one of the most prevalent causes of preventable disease;1,2 and

Accepting that current lead levels in Americans are between 100 and 1,000 times those occurring in humans prior to the current technological era,3 and that new biomedical data demonstrate that lead is toxic to fetuses, children, and adults at levels of exposure which are endemic,4,5 and that existing sources of lead affect millions of Americans through contamination of air, water, food, dusts, and soils; and

Noting that toxicity has been described by the US Environmental Protection Agency and the Agency for Toxic Substances and Disease Registry at levels that are experienced by more than 16 percent of all children in the United States, and 55 percent of Black children in poverty; and

Noting that the sequelae of lead toxicity are persistent and associated with chronic diseases of the cardiovascular system6,7 and kidney,8 as well as impaired growth,9 hearing,10 learning and social development of children;11-13 and

Noting that various agencies of the federal government, including the Environmental Protection Agency, Occupational Safety and Health Administration,14 Consumer Product Safety Commission,15 Department of Housing and Urban Development,16 and Food and Drug Administration17 have taken actions to identify and reduce certain sources of lead exposure in the environment and workplace, but that these actions are uncoordinated and incomplete; and

Recognizing that the current uncoordinated approach to preventing lead toxicity has resulted in inconsistent public policy and lack of effective actions by responsible government agencies and inadequate funding for abatement programs, particularly those related to removing leaded paint from old housing; and

Recognizing that environmental lead exposure results from both historic uses of lead, and ongoing uses of lead in industry and in consumer products, many of which are replaceable or reducible; and

Recognizing that the areas of highest lead exposure are also the areas of the nation with highest unemployment and greatest need for low-cost housing; and

Recognizing that the social costs of unidentified lead exposure exceed $1.5 billion18 per year for remedial education, and that lead exposure is related to school dropout, attention deficit, and reading disability; and

Considering the enormous costs exerted by lead on public health and the inequitable distribution of these costs on American society; therefore

  1. Reaffirms the recommendations provided by APHA policy statement #8508;19 and further
  2. Recommends the establishment, periodic review, and modification by the Centers for Disease Control of health-based guidelines for prevention of lead poisoning in both adults and children. These guidelines must recognize the newest health and environmental data, and will be more stringent than current standards;
  3. Urges that the eradication of lead toxicity be a major public health goal in the US and that appropriate federal, state, and local funding be provided for this purpose;
  4. Encourages actions by the World Health Organization to achieve similar ends world-wide;
  5. Recommends coordination of the actions of federal agencies to reduce ongoing sources of lead in the environment and to facilitate the rapid abatement of lead sources associated with past uses such as lead in gasoline, lead smelters, and lead-based paint in housing;
  6. Encourages research on the potential carcinogenicity, neurotoxicity, reproductive toxicity, and potential effects of lead on aging populations;
  7. Recommends the development of training and certification programs in safe lead abatement and housing rehabilitation and requires that all workers and contractors who undertake lead abatement be properly certified; and that all lead abatement work adhere, at a minimum, to the OSHA lead standard for industry;
  8. Recommends that abatement programs where possible be designed to offer employment opportunities to residents of leaded neighborhoods; and
  9. Urges that adequate funds be appropriated to enable low and moderate income residents and property owners to undertake residential lead abatement efforts.
