Background: Toxicological studies have raised concerns regarding the neurotoxic effects of per- and polyfluoroalkyl substances (PFAS). However, observational evidence from human studies investigating the association between childhood PFAS and neurobehavior is limited and remains unclear. Objectives: To examine whether childhood PFAS concentrations are associated with neurobehavior in children at age 8 years and whether child sex modifies this relationship. Methods: We used data from 208 mother-child dyads in the Health Outcomes and Measures of the Environment (HOME) Study, a prospective pregnancy and birth cohort (Cincinnati, OH, USA). We quantified PFAS in child serum at 3 and 8 years. We assessed …

Evaluating And Regulating Lead In Artificial Turf, Gregory Van Ulirsch, Kevin Gleason, Shawn Gerstenberger, Deaphne B. Moffett, Glenn Pulliam, Tariq Ahmed, Jerald Fagliano

Environmental & Occupational Health Faculty Publications

Background: In 2007, a synthetic turf recreational field in Newark, New Jersey, was closed because lead was found in synthetic turf fibers and in surface dust at concentrations exceeding hazard criteria. Consequently, public health professionals across the country began testing synthetic turf to determine whether it represented a lead hazard. Currently, no standardized methods exist to test for lead in synthetic turf or to assess lead hazards.

Objectives: Our objectives were to increase awareness of potential lead exposure from synthetic turf by presenting data showing elevated lead in fibers and turf-derived dust; identify risk assessment uncertainties; recommend that federal and/or …

Lead-contaminated candies from Latin America are beginning to gain attention in the public media1,2 and in the medical literature.3–5 These candies come from a number of sources and are manufactured outside Food and Drug Administration regulatory control. In 2005, we sampled 50 imported Latin American candies sold in Southern Nevada. A total of 20 (40%) tested positive with an average lead content of 1.46  0.27 mg/kg in the candies’ wrappers and straws, based on standard Graphite Furnace Atomic Absorption Spectrophotometry methodology. Given these results, the Southern Nevada Health District issued a cease-and-desist order on February 13, 2006, to local …

The Status Of Childhood Lead Poisoning And Prevention In Nevada, Usa, Anne Rothweiler, Elena E. Cabb, Shawn Gerstenberger

Environmental & Occupational Health Faculty Publications

One of the first steps in addressing the problem of childhood lead poisoning is to identify the possible sources of exposure in specific communities and target high-risk populations with appropriate interventions. Due to several factors, such as lack of funding and lack of blood lead reporting, little information exists regarding the occurrence of childhood lead poisoning and the prevalence of potential exposure sources in the state of Nevada. Following the recent establishment of a Nevada-based Lead Poisoning Program, we compiled the most current information available on Nevadans, and use this knowledge to suggest future research objectives and outreach activities for …
