Atmosphere|Free Full-Text|Minimizing Contamination

Palmitic acid (C16:0) and stearic acid (C18:0) are among the most abundant products in cooking emission,and thus could serve as potential molecular tracers in estimating the contributions of cooking emission to particulate matter (PM2.5) pollution in the atmosphere. Organic tracer analysis in filter-based samples generally involves extraction by organic solvents,followed by filtration. In

Distribution of normalized water‐leaving radiances at UV

1. Introduction [2] Normalized water‐leaving radiance (nL w (λ) in μW cm −2 sr −1,where λ refers to wavelength in nm) is defined as the radiance that would emerge from the ocean in the absence of atmosphere,with the Sun at zenith,at the mean Earth‐Sun distance [Gordon and Clark,1981; Gordon,2005].Belonging to apparent optical properties (AOPs),nL w (λ) is dependent on both

Collecting and Processing Stream Water Samples

Samples collected for chorophenoxy-acid herbicides and carbamates (NWQL schedules 2050 and 2051) use the high-pressure liquid-chromatography (HPLC) method. These synthetic-organic compounds in stream water interact with sediment particles through sorptive processes; therefore,it is important to separate the solid phase from the sample as soon
