Significance Despite numerous publications reporting the accumulation of petroleum hydrocarbons associated with Deepwater Horizon spill on seafloor, mechanisms their delivery to seafloor remain unclear. We demonstrate sedimentation black carbon derived from in situ burning surface oil slicks for about 2 mo following cessation while other contaminants spill, including bioactive barium drilling mud, continued sediment at least 5 after well was capped. also show that episodic sinking...
Exposure to PM2.5 is associated with hundreds of premature mortalities every year in New York City (NYC). Current air quality and health impact assessment tools provide county-wide estimates but are inadequate for assessing benefits at neighborhood scales, especially evaluating policy options related energy efficiency or climate goals. We developed a new ZIP Code-Level Air Pollution Policy Assessment (ZAPPA) tool NYC by integrating two reduced form models─Community Quality Tools (C-TOOLS)...
Differences in exposures and resources to manage personal health contribute persistent inequities air pollution burden despite vast quality improvements over the past 2–3 decades United States. These factors are, partly, linked historic racist practices, such as redlining, a discriminatory housing policy that was practiced legally between 1935 1968. Using 100 m × resolution land-use regression predicted surfaces of PM2.5 constituents (black carbon, nickel, vanadium, copper) source...
Common soil test methods were compared with 0.01 M CaCl2 extraction to determine their relative abilities extract and estimate phytoavailability of Cu Zn. In aged metal-spiked soils, all tests evaluated (Mehlich 3, diethylenetriaminepentaacetic acid [DTPA], Morgan, modified CaCl2) showed a linear relationship extractable total Zn for both types studied. The fraction extracted by aggressive DTPA) was much higher than the CaCl2, Morgan being intermediate. Although revealed be more available in...
Previous source apportionment analyses of New York City (NYC) PM2.5 have found that transported pollution can account for up to half total fine particulate matter (PM2.5) mass. In recent years, several local and federal emissions regulations on both the transportation energy sector been introduced, such as Clean Heavy-Duty Bus Truck Rule, policies related NYC Heat Program. Since implementation these regulations, there limited studies regional transport air into NYC. This paper aims quantify...
Fine particulate matter (PM2.5), levels of which are about 6 times the 2014 WHO air quality guidelines for 190 cities in China, has been found to be associated with various adverse health outcomes. In this study, personal PM2.5 exposures were monitored along a fixed routine that included 19 types non-residential micro-environments (MEs) on 4 hazy days (ambient 292 ± 70 μg m-3) and 2 non-hazy (55 16 Nanjing, China using miniaturized real-time portable sensors also collect integrated filters...
Reducing cadmium (Cd) exposure in Cd-polluted areas Asia is urgently needed given the toxic effects of Cd. The short-term and long-term benefits lowering Cd are unknown because its long half-life body. We aimed to investigate whether an intervention with low-Cd rice a contaminated area China reduced urinary (UCd) levels improved blood pressure kidney function outcomes compared no-intervention consumers high-Cd same region. 106 non-smoking subjects were divided into three treatment groups:...
Response management and damage assessment during after environmental disasters such as the Deepwater Horizon (DWH) oil spill require an ecological baseline a solid understanding of main drivers ecosystem. During DWH event, large fraction spilled was transported to depth via sinking marine snow, routing unexpected emergency response planners. Because knowledge particle export in Northern Gulf Mexico how it varies spatially temporally limited, we conducted detailed potential deep (~1400 m...
High rates of hospitalization and death disproportionately affected Black, Latino, Asian residents New York City at the beginning COVID-19 pandemic. To suppress transmission, implemented a workforce community engagement specialists (CESs) to conduct home-based contact tracing when telephone numbers were lacking or telephone-based efforts unsuccessful disseminate information sanitary supplies.We describe recruitment, training, deployment multilingual CES with diverse sociodemographic...
Using spatially- and temporally-resolved data from the New York City Community Air Survey (NYCCAS) State (NYS) Department of Environmental Conservation (DEC) network, we characterized changes in fine particulate matter (PM2.5) nitrogen dioxide (NO2) following COVID-19 shutdown NYC (3/20/20 – 6/7/20). Difference-in-difference analysis PM2.5 NO2 measured at 93 sites were used to estimate change citywide pollution attributable shutdown. We also quantified how these pollutant varied among...
Exhaled breath condensate (EBC) provides a relatively easy, non-invasive method for measuring biomarkers of inflammation and oxidative stress in the airways. However, levels these EBC are influenced, not only by their lung lining fluid but also volume water vapor that condenses during collection. For this reason, use biomarker dilution has been recommended. Urea proposed utilized as promising due to its even distribution throughout body low volatility. Current urea analytical methods either...
Although short-duration elevated exposures (peak exposures) to pollutants may trigger adverse acute effects, epidemiological studies understand their influence on different health effects are hampered by lack of methods for objectively identifying peaks. Secondhand smoke from cigarettes (SHS) in the residential environment can lead peak exposures. The aim this study was explore whether peaks continuous PM2.5 data indicate SHS exposure. A total 41 children (21 with and 20 without exposure...
This study validates the analysis of polycyclic aromatic hydrocarbons (PAHs) in microgram levels particulate matter (PM) collected on filters by two low-flow rate, real-time monitors, microPEM™ and microAeth®. Particle-associated PAHs were analyzed a coupling gas chromatograph to sensitive, atmospheric-pressure laser ionization-mass spectrometer. Air samples over course one or days living room fourth-floor apartment New York City. Three types samplers, aforementioned personal samplers...
Contact tracing is an important public health tool for curbing the spread of infectious diseases. Effective and efficient contact involves rapid identification individuals with infection their exposed contacts ensuring isolation or quarantine, respectively. Manual via telephone call digital proximity app technology have been key strategies in mitigating COVID-19. However, many people are not reached COVID-19 due to missing numbers nonresponse calls. The New York City Trace program augmented...
We assessed the timeliness of contact tracing following rapid-positive COVID-19 test result at point-of-care testing (POCT) sites in New York City (NYC).Interviewed case-patients to elicit exposed contacts and conducted exposure notifications.Twenty-two POCT NYC, 2 NYC international airports, 1 ferry terminal.Case-patients with results their named contacts.We quantified proportions interviewed individuals notified between dates interviews or notifications.In total, 11 683 were referred for...
BACKGROUND AND AIM: To inform pollution policy, we estimated air quality and health impacts attributable to source changes in New York City (NYC). METHOD: Air pollution, mortality, morbidity data were obtained from US EPA's Quality System, NYC Department of Health Mental Hygiene Vital Statistics, Statewide Planning Research Cooperative respectively. "Before" (2005-2007) "after" (2013-2015) periods compared based on policy events seasonal patterns. PM2.5 apportionment was performed using...
