About half of the surface oil floating on Gulf Mexico in aftermath 2010 Deepwater Horizon spill was transformed into oxygenated hydrocarbons (OxHC) within days to weeks. These OxHC persist for years oil/sand aggregates nearshore and beach environments, there is concern that these might represent a long-term source toxic compounds. However, because this fraction continuum transformation products are not well chemically characterized, it included current fate effect models. This challenges an...
Photoproducts can be formed rapidly in the initial phase of a marine oil spill. However, their toxicity is not well understood. In this study, was irradiated, chemically characterized, and tested for three copepod species (Acartia tonsa, Temora longicornis, Calanus finmarchicus). Irradiation led to depletion polycyclic aromatic hydrocarbons (PAHs) n-alkanes residues, along with an enrichment aliphatic photoproducts. Target lipid model-based calculations PAH units predicted that toxicities...
Abstract The occurrence, trends and sources of soot black carbon (BC) in coastal sediments are poorly understood, particularly during the Anthropocene. Two sediment cores, covering last ∼100 years from US East Coast, off North Carolina Florida Straits, were analyzed for organic (OC), BC fluxes sources. 0.1 g cm −2 year −1 at both sites accounted 8%–22% total OC. Carbon stable isotope values indicated OC to be marine origin, while was mostly terrestrially derived, C3‐plant material....
Abstract Boswellia serrata has been shown to reduce cerebral edema following radiation in brain tumors by Kirste et al a prospective, randomized, placebo-controlled, double-blind pilot trial. In the study dose of used was 4200mg/day, and well tolerated. We report 2 patients who took doses 10x that which recommended, after inadvertently buying much higher online. Both obtained significant reduction enhancing disease on MRI. The daily 42000mg/day tolerated well, with only mild dysphonia one...
ABSTRACT 2017-186 Oxygenated hydrocarbons (OxHC) are major and persistent hydrocarbon degradation products that formed after oil spills. However, there still knowledge gaps related to formation, fate effect of these products. The objective this study was find if the OxHCs present in weathered oils more or less toxic bioaccumulative than their parent compounds. In study, we first systematically investigated bioaccumulation potential toxicity oxygenated weathering products, using predictions...
Photoproducts can be formed rapidly in the initial phase of a marine oil spill. However, their toxicity is not well understood. In this study, was irradiated, chemically characterized, and tested for three copepod species (A. tonsa, T. longicornis, C.finmarchicus). Irradiation led to depletion polycyclic aromatic hydrocarbons (PAHs) n-alkanes residues, along with an enrichment aliphatic photoproducts. Target lipid model-based calculations PAH toxic units (TU-PAH) predicted that toxicities...
The transport of semi-volatile organic pollutants is impacted by monsoon and seasonal variations over the South China Sea (SCS). In this study, we analyzed polycyclic aromatic hydrocarbons (PAHs) basin areas (western SCS central SCS) island (Yongxing Island Yongshu Island) in 2017. Gaseous PAHs (0.17-1.4 ng m -3 ) showed spatial distinctions their composition sources among areas. terms distributions, spring concentrations were generally higher than autumn, they highest followed winter...
