Determination of Lead and Nickel Levels in Lipsticks and Potential Health Hazards to Users in Babylon, Iraq

The effect of inoculation of Trichoderma harzianum strain A-34 and immersion time in water on the germination process of common bean variety “Cul 156” was determined. A completely randomized design was used, with a 3 x 3 distributed factorial arrangement: Factor A (time of immersion in water A1, A2 and A3) and B (dose of Trichoderma B1, B2 and B3) with a concentration of 2. 109 u.f.c. Indicators evaluated: germination tests (start, maximum and cumulative), germination rates and speed, hypocotyl and radicle length and their relationship. The results showed that the use of Trichoderma with a dose of 30 g and two hours of seed immersion significantly influenced the maximum germination potential in the germination rate and speed compared to the other treatments and the highest values in the length of the hypocotyl and the radicle. And their relationship. The combination of Trichoderma with a dose of 30 g with two hours of immersion was the treatment that achieved the highest physiological response of the “Cul 156” variety during the experiment, which could constitute an advantage for the establishment of future plantations.
