Objectives: To investigate, measure and assess the food consumption pattern of the adult population living in Beirut, Lebanon, and to identify inadequate or excessive intake of food groups particularly linked to non-communicable diseases. , with 73.6% of subjects consuming less than the recommended 2 servings of fish per week. Dairy products contributed 243.1 g day 21 or 10.9% of daily energy intake, and milk was the least consumed dairy product (56.8% of consumers). The intake of added fats and oils, excluding those in cooked recipes, was 20.4 g day 21 ; olive oil was not used in cooking but was added solely at the table and its mean intake was 5 g day 21. The consumption of butter was low (0.86 g day 21 ) and vegetable oil was the type of fat mostly used in cooking. The average intake of alcoholic beverages was low (33.6 g day 21 ), accounting for 0.7% of total energy intake. Women had significantly higher intakes of milk, dairy products, vegetables and coffee than men (P , 0.05). The percentage of women who reported the use of low-fat items was significantly higher than that of men. Younger people (25 -34 years) ate significantly more meat, sugar, alcoholic beverages and soft drinks, and consumed significantly less cooked vegetables and legumes, than older ones (P , 0.05). Conclusions: The rather high contribution of fat to daily energy intake, the low intake of fish and the relatively high percentage of people consuming less than the recommended amount of fruits and vegetables observed in this study suggest that the adult Lebanese population is at increased risk of cardiovascular diseases, obesity and other non-communicable diseases, which provides the basis for recommending increased intakes of fish, particularly fatty fish, and fruits and vegetables.

Years of unregulated mining activity have left hundreds of abandoned quarries across Lebanon. Satellite images show that the number of quarries and areas they cover increased, from 784 quarries covering 2897 ha in 1989, to 1278 quarries covering 5267 ha in 2005. This paper presents a comprehensive approach to assess the impact of quarrying activities on scarce Eastern Mediterranean natural resources. The assessment is based on the computation of spatial indicators such as rainfall, slope gradient, vegetation cover, soil erosion risk, and rock infiltration, using GIS to appraise critical impacts on the Lebanese ecosystem. Compared with the 1989 baseline, the area consumed by quarries in 2005 increased more than three times over former arable lands, one third for forest lands and doubled for pasture lands. Quarries additionally destroyed 676, 137, and 737 ha of productive lands, respectively. The comparison of quarry distribution with the land capability map revealed that quarries are found mainly on productive soils, consuming 1314 ha in 1989 and 2192 ha in 2005 of prime lands. A total of 87 per cent of studied quarries represent serious hazards to groundwater quality. In general, a total of 272 quarries have high impact, 657 quarries have moderate impact, and 349 quarries have low impact on natural ecosystems. Analyzed data revealed that around 62 per cent of the quarries are located in a highly unsuitable environment. This paper presents recent findings from the Eastern Mediterranean for territorial suitability assessment of quarries to be considered in the frame of natural resources and coastal ecosystems management.

Human exposure to toxic chemicals is suspected of being responsible for a wide range of human health disorders. This study is the first in Lebanon to evaluate the dietary exposure of an adult urban population to three heavy metals (lead, cadmium and mercury) and to radionuclides. Exposure assessment was performed by means of the total diet study approach as recommended by the Word Health Organization. Five 'total diets' were collected during 2003-04. Average and maximal consumer exposure estimates to heavy metals were calculated and compared with appropriate reference values and with intakes reported from other countries. The average dietary intakes of lead, cadmium and mercury represented 7, 17 and 5.6%, respectively, of the appropriate provisional tolerable weekly intakes (PTWI). The mean dietary intake of methylmercury represented 17.5% of the appropriate PTWI. Cs-134 and I-131 were not detected in any of the food samples. Traces of Cs-137 were only found in five food samples. The exposure assessment conducted places Lebanon among countries least exposed to heavy metals through the diet and it highlights the safety of the food supply from radioactive contamination.
