Summary: This paper introduces a novel dielectric spectroscopic technique for investigating the freshness and adulterated agents in milk. The study reveals an inverse relationship between temperature and shelf-life, as well as the real part of the complex permittivity (epsilon') of the samples at frequencies ranging from 0.1 to 3 GHz. A linear relationship is also observed between epsilon' and epsilon, storage time, and water content at 2 GHz. Furthermore, a linear relationship is found between the concentrations of five adulterants' agents and both epsilon' and epsilon parts. This technique has the potential to be used for rapid online monitoring of milk quality in milk production facilities.

Summary: Phytoremediation of metals from water and nutrient media exposed to waste metal cutting fluid was tested using Azolla imbricata. Results showed that biomass was higher in nutrient media than in water media without waste metal cutting fluid. However, growth failed when exposed to high concentrations of waste metal cutting fluid. Correlation analysis revealed that biomass was positively affected by temperature and negatively affected by humidity and metal accumulation. The average accumulations of Al, Cd, Cr, Fe, Pb, and Zn were observed and the bioconcentration factor indicated Azolla imbricata acts as a hyperaccumulator of Zn and as an accumulator or excluder of other metals. Overall, the phytoremediation performance of Azolla imbricata in multi-metal-contaminated waste metal cutting fluid was high in water media under all environmental conditions. The use of water media was determined to be an economically feasible approach for the removal of metals from waste metal cutting fluid.
