Abstract: This study was conducted to find out the effect of physical factors such as temperature and humidity on the black seed, based on folk medicine accounts that recommend chewing the black seed and moistening it with saliva. to take advantage of its nutritional properties [1]. Laser induesd breakdown spectroscopy technique were used to analyze black seed components that were exposed to heat and humidity to varying degrees and at different times and were purchased in the local market for the 2019 harvest. Using a laser (Nd: YAG) with a wavelength of 1064 nm with a pulse energy of 120 mJ, a width of 10 ns and a frequency of 10 Hz, the plasma used in the system was generated in a quasi-experimental method based on the idea that the plasma is homogeneous. Electron density and plasma temperature was calculated applying Saha-Boltzmann equation and Boltzmann plot method. The generated plasma was concentrated on the surface of the black seed powder and paste and the essential micronutrients were determined in the carbon black seeds. spectroscopic study was performed using calibration free LIBS procedure. The relative concentration for (Ca) in black seeds were obtained. The results showed that the black seed was not affected by humidity and temperature factors due to the stability of the presence of elements in it with the difference of the relative concentration of some elements. In black seed kernels, Ca is more, but Na is less. With different macronutrient ratio of potassium, iron, sulfur and sodium.
