Background: Medical laboratory workers are frequently exposed to a wide range of chemicals. This exposure can have adverse effects on their health. Furthermore, a knowledge lack of the chemical risk increases the likelihood of exposure. The chemical risk assessment reduces the risk of exposure to hazardous chemicals and therefore, guarantees health and safety of the workers. Method: The chemical risk assessment was conducted using a modified INRS method, according to the new CLP Regulation, of 11 unit laboratories in a Moroccan medical laboratory. Observation of each workstation and analysis of safety data sheets are key tools in this study. Results: A total of 144 substances and reagents that could affect the health of the analytical technicians were identified. Among these products, 17% are concerned by the low priority risk score, with 55% concerned by the average priority risk score and 28% concerned by the high priority risk score. This study also enabled to better identify the chemical agents that have restrictive occupational exposure limit value and controls were conducted to this effect. On the basis of the results obtained, several corrective and preventive measures have been proposed and implemented. Conclusion: Risk assessment is essential to ensure the health and safety of workers and to meet regulatory requirements. It enables to identify all the risky manipulations and to adopt appropriate preventive measures. However, it is not a one-time activity but it must be continuous in order to master the changes and thus ensure the best safety of all.

Therapy combination is known for less side effects and higher efficacy. Essential oils (EOs) and mixture from two wellknown plants (Syzygium aromaticum and Pelargonium graveolens) were tested for in vivo antioxidant and anti-inflammatory activities. The chemical analysis of the investigated Oils has lead to the identification of Eugenol (74.06%), Caryophyllene (11.52%) and Carvacrol acetate (7.82%) as the major element in S. aromaticum; while P. graveolens was much higher in Citronellol (30.77%), 10-epi-γ-Eudesmol (22.59%), and Geraniol (13.95%). In our pharmacological screening, both EOs demonstrated good antioxidant effects; especially S. aromaticum activity was much higher. In contrast, the in vivo investigation of the antioxidant activity using antioxidant enzymes (MDA, SOD and CAT) in the protozoa model (Tetrahemena pyriformis) demonstrated a higher protective effect of P. graveolens and EOs mixture. On the other hand, EOs demonstrated anti-inflammatory effect on the two phases of inflammation in the carrageenan induced edema model. Results from this study indicate that EOs from S. aromaticum and P. Graveolens can be used as a multitarget therapy.
