OBJECTIVES We assessed the extent of exposure to lead, cadmium, and mercury in the New York City (NYC) adult population. METHODS We measured blood metal concentrations in a representative sample of 1,811 NYC residents as part of the NYC Health and Nutrition Examination Survey, 2004. RESULTS The geometric mean blood mercury concentration was 2.73(More)
BACKGROUND Studies have consistently documented declines in respiratory health after 11 September 2001 (9/11) among surviving first responders and other World Trade Center (WTC) rescue, recovery, and clean-up workers. OBJECTIVES The goal of this study was to describe the risk of newly diagnosed asthma among WTC site workers and volunteers and to(More)
Pesticides are of interest in etiologic studies of breast cancer because many mimic estrogen, a known breast cancer risk factor, or cause mammary tumors in animals, but most previous studies have been limited by using one-time tissue measurements of residues of only a few pesticides long banned in the United States. As an alternative method to assess(More)
BACKGROUND Drinking water contaminated by wastewater is a potential source of exposure to mammary carcinogens and endocrine disrupting compounds from commercial products and excreted natural and pharmaceutical hormones. These contaminants are hypothesized to increase breast cancer risk. Cape Cod, Massachusetts, has a history of wastewater contamination in(More)
Objectives: To estimate the relative contribution of environmental and genetic factors disposing towards the development of melanoma. Methods: We investigated risk factors for melanoma in a case–control study conducted among 185 North American twin pairs in which one was diagnosed with melanoma and the other (the co-twin of the case) was not. We considered(More)
BACKGROUND Organophosphates and pyrethroids are the most common classes of insecticides used in the United States. Widespread use of these compounds to control building infestations in New York City (NYC) may have caused higher exposure than in less-urban settings. OBJECTIVES The objectives of our study were to estimate pesticide exposure reference values(More)
BACKGROUND Mercury is a toxic metal that has been used for centuries as a constituent of medicines and other items. OBJECTIVE We assessed exposure to inorganic mercury in the adult population of New York City (NYC). METHODS We measured mercury concentrations in spot urine specimens from a representative sample of 1,840 adult New Yorkers in the 2004 NYC(More)
PURPOSE Health is important for continued employment and therefore continued accrual of occupational exposure; furthermore, steady employment can benefit health. Consequently, bias can occur in estimates of cumulative exposure-mortality associations. This has been called the healthy worker survivor effect (HWSE). The processes associated with the HWSE tend(More)
BACKGROUND Cockroaches and mice, which are common in urban homes, are sources of allergens capable of triggering asthma symptoms. Traditional pest control involves the use of scheduled applications of pesticides by professionals as well as pesticide use by residents. In contrast, integrated pest management (IPM) involves sanitation, building maintenance,(More)
In 2004, the New York City (NYC) Health and Nutrition Examination Survey measured the highest blood mercury levels in Asian and foreign-born Chinese demographic groups. Fish consumption was the strongest predictor of exposure. The survey did not inquire about consumption of individual species, and subsequent visits to fish markets serving the Asian(More)
