This study aimed to characterize spatial/temporal variations of ambient volatile organic compounds (VOCs) using a community-scale monitoring approach and identify the main sources of concern in Paterson, NJ, an urban area with mixed sources of VOCs. VOC samples were simultaneously collected from three local source-dominated (i.e., commercial, industrial, and mobile) sites in Paterson and one ba...

Volatile aroma compounds were evaluated in USDA Top Choice and Select beef top loin steaks cut 1.3 cm (THIN) or 3.8 (THICK) cooked on a commercial flat grill at 177°C (LOW) 232°C (HIGH) surface temperature. Gas chromatography/mass spectrophotometry was used to evaluate volatile compounds. had more 2-octene less trimethyl pyrazine (P < 0.05) THIN than THICK steaks, whereas unaffected by s...

Quality control of liquid raw materials arriving on an industrial manufacturing site is typically performed in a dedicated laboratory using time- and chemicals-consuming analytical methods. Herein, we report the successful development handheld near-infrared spectroscopy method for rapid, low-cost testing organic solvents. Our methodology enables classification solvents with 100% accuracy quanti...
