The effect of different educational interventions on schoolchildren's knowledge of earthquake protective behaviour in Israel

Knowledge of appropriate behaviour during an earthquake is crucial for prevention of injury and loss of life. The Israeli Home Front Command conducts a yearly earthquake education programme in all Israeli schools, using three types of educational interventions: lectures, drills and a combination of the two. The aim of this study was to evaluate the effectiveness of these interventions in providing students with knowledge. We distributed a questionnaire to 2,648 children from the 5th and 6th grades in 120 schools nationwide. Knowledge scores for both 5th and 6th grades were increased, regardless of type of intervention, compared to the non-exposure group. A combined intervention of lectures and drills resulted in the highest knowledge scores. Our findings suggest that for the age group studied a combination of lectures and drills will likely prepare students best for how to behave in the event of an earthquake.     

The effects of pesticides on greenhouse workers and their produced products

Pesticides are chemicals used in agriculture but are known to produce adverse effects on humans. In this study, blood activities of superoxide dismutase (SOD), catalase (CAT), aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transaminase, lactate dehydrogenase (LDH), and levels of malondialdhyde (MDA) were determined in 44 greenhouse workers (24 tomato workers, 20 clove workers) and in tomato (24 samples) and clove (20 samples) products. At the end of this study, blood MDA levels and activities of ALT, AST, and LDH levels in greenhouse workers were significantly increased while SOD and CAT activity levels fell significantly. Pesticide residues were not found in agricultural worker blood. Malathion residues (average 0.8?ppm) were detected in tomatoes (8 samples) in these greenhouses. Data suggest that the health of the greenhouse workers may be adversely affected by pesticides.
