BACKGROUND Approximately 40,000 rescue and recovery workers were exposed to caustic dust and toxic pollutants following the 11 September 2001 attacks on the World Trade Center (WTC). These workers included traditional first responders, such as firefighters and police, and a diverse population of construction, utility, and public sector workers. METHODS To(More)
BACKGROUND The World Trade Center (WTC) attacks exposed thousands of workers to hazardous environmental conditions and psychological trauma. In 2002, to assess the health of these workers, Congress directed the National Institute for Occupational Safety and Health to establish the WTC Medical Monitoring and Treatment Program. This program has established a(More)
BACKGROUND More than 50,000 people participated in the rescue and recovery work that followed the Sept 11, 2001 (9/11) attacks on the World Trade Center (WTC). Multiple health problems in these workers were reported in the early years after the disaster. We report incidence and prevalence rates of physical and mental health disorders during the 9 years(More)
BACKGROUND Longitudinal symptoms of post-traumatic stress disorder (PTSD) are often characterized by heterogeneous trajectories, which may have unique pre-, peri- and post-trauma risk and protective factors. To date, however, no study has evaluated the nature and determinants of predominant trajectories of PTSD symptoms in World Trade Center (WTC)(More)
BACKGROUND This study examined the prevalence, correlates, and perceived mental healthcare needs associated with subsyndromal PTSD in police involved in the World Trade Center (WTC) rescue and recovery effort. METHODS A total of 8466 police completed an interview/survey as part of the WTC Medical monitoring and Treatment Program an average of four years(More)

Recent studies show that respiratory illness and post-traumatic stress disorder (PTSD) are the hallmark health problems, but relationships between them are poorly understood. The current study(More)
It has been known for a number of years that chromium-containing mine slags were used as landfill in residential areas of Hudson County, New Jersey. Since one of the major lesions induced in intact cells by chromate is the DNA-Protein crosslink, we have used this lesion as a biomarker of biological effect of chromium (Cr) exposure. We have previously(More)
BACKGROUND World Trade Center (WTC) rescue and recovery workers were exposed to a complex mix of pollutants and carcinogens. OBJECTIVE The purpose of this investigation was to evaluate cancer incidence in responders during the first 7 years after 11 September 2001. METHODS Cancers among 20,984 consented participants in the WTC Health Program were(More)
Chromium waste slag containing potentially hazardous levels of hexavalent chromium was used as fill material at more than 160 residential, industrial, and recreational sites. Persons living or working in the vicinity of the sites may have been exposed through inhalation, ingestion, or skin contact with contaminated soils and dusts. In 1992-1993, the New(More)
