The extractions were carried out by pressurized liquid extraction (Dionex, ASE-300) with n-hexane:acetone (1:1), static time 10 min at 125 °C, 4 cycles, 60% flush and 60 s. purge. The extracts were concentrated to approximately 1 mL using a Genevac Rocket Synergy Evaporator (Thermo ...
[587] padded a needle-punched nonwoven thermal linear with 5% aerogels dispersed in acetone. As the aerogels are comprised of extremely fine nanopores with 99.8% air, they enhance the insulation features of the thermal linear under radiant heat and/or flame exposures [588]. Similarly, the ...
Environmental Protection Agency (EPA) headquarters during renovations; (2) Gulf War veterans; (3) pesticide exposure among casino workers; (4) exposure to aircraft oil fumes; (5) the World Trade Center tragedy; (6) surgical implants; (7) moldy environments; and (8) tunnel workers exposed to...
while emitting half of the concentration of PM2.5 compared to three stone fire, emitted more than double the concentration (~100 µg/m3) of elemental carbon as well as the highest concentration of nitrous oxides (NOx/NO2) and acetone compared to all cookstoves tested (Fedak et al., 2019...
VOCs encompass a wide range of compounds including, but not limited to, aromatics (toluene, xylene), esters and ketones (ethyl acetate, acetone) and terpenes (pinene, limonene, camphor, menthenol), the effects of which have yet to be fully understood. Of note, knowledge on hazards ...
[3]. The toenail polish was removed with an acetone-based solution before collection. Blood Lead Level (PbB) Blood samples were analyzed by GFAAS as described by Menezes-Filho et al. [29]. The Pb concentration was determined from the calibration curve obtained by diluting a standard Pb ...
However, as seen in Figure 2, IPA and/or acetone concentrations could reach a very high level during short periods in a specific task, polluting the clean room with VOCs. TVOC concentrations, most of it as IPA, reached as high as 24 ppm for a short time due to the cleaning of hot me...
(pH 7.4), and permeabilized with ice-cold acetone. The samples were incubated with two antibodies overnight at room temperature, a rabbit monoclonal anti-cleaved caspase-3 antibody (Clone 5A1E, dilution 1:200, Cell Signaling Technology Inc., Danvers, MA, USA) that was labeled with Atto488 ...
