Cytotoxicity of water supply in a Palestinian refugee camp and a Syrian informal tented settlement in Lebanon.

Deficient water, sanitation, and hygiene (WASH) significantly account for a high burden of disease across the globe. Lebanon, an Eastern Mediterranean lower-middle-income country with a polluted environment, a fragmented healthcare system, and an ongoing severe economic crisis, faces serious challenges in sustaining safe water supplies, especially in vulnerable communities, while also hosting the world highest refugee population per capita. This study aimed to examine the mutagenicity, and the estrogenic and androgenic activities of water supplies, across both a Palestinian refugee camp and a Syrian informal settlement.

Feature selection approaches for predictive modelling of cadmium sources and pollution levels in water springs.

The World Health Organization lists cadmium (Cd) as one of the top ten chemicals of public health concern. Cd is toxic at relatively low exposure levels and has acute and chronic effects on both health and the environment. In this study, we investigate a suite of data-driven methods that could assist decision-makers in estimating Cd levels in water springs, and in identifying polluting sources.

Towards a renewed public health regulatory and surveillance role in water, sanitation and hygiene (Editorial).

Evidence from the burden of disease studies indicates that improving water, sanitation and hygiene (WSH) is a primary disease prevention measure. It prevents 57% of diarrheal deaths, contributes to prevention and management of neglected tropical diseases, and is the first line of defense against Cholera. Moreover, water and sanitation (W&S) services and hygiene contribute to programme initiatives including new-born, child and maternal health; infection prevention and control; universal health care; antimicrobial resistance; and health emergencies.

Assessment of toxic metals and phthalates in children's toys and clays.

Toxic metals and phthalates are introduced in the manufacturing of plastic toys and modeling clays. In Lebanon, inexpensive plastic toys and modeling clays (sold in dollar stores) are affordable and popular, and there is no legislation to monitor or regulate such toys. This study aimed to assess the quality of inexpensive plastic toys and modeling clays imported in Lebanon.

Management of microbial food safety in Arab countries.

Microbial food safety remains a major economic and public health concern in Arab countries. Over the past several years, many of these countries have attempted to revise and upgrade food quality control and surveillance programs; however, these systems vary in scope and effectiveness. This review addresses the major reported foodborne outbreaks and multidrug resistance of pathogenic microorganisms isolated from food products.

Speciation of metals in bed sediments and water of Qaraaoun Reservoir, Lebanon.

Determination of only total element in sediments does not give an accurate estimate of the likely environmental impacts. Speciation study of metals in sediment provides information on the potential availability of metals (toxic) to biota under various environmental conditions. In water, the toxic metal specie is the free hydrated metal ion.

The challenges of sustainable access to safe drinking water in rural areas of developing countries: case of Zawtar El-Charkieh, Southern Lebanon.

Adequate and safe water is important for human health and well-being, economic production, and sustainable development. Failure to ensure the safety of drinking water may expose the community to the risk of outbreaks of waterborne and infectious diseases. Although drinking water is a basic human right, many people do not have access to safe and adequate drinking water or proper sanitation facilities.

Effect of women's perceptions and household practices on children's waterborne illness in a low income community.

An ecosystem approach to human health was adopted in a community-based study carried out in Bebnine, an underserved town in Lebanon. The objective of the study is to examine the association between women's household practices and diarrhea among children in a setting where contaminated drinking water and intestinal diseases are common. A total of 280 women were randomly selected and interviewed using a structured questionnaire.

Effectiveness of wastewater management in rural areas of developing countries: a case of Al-Chouf Caza in Lebanon.

Alike many developing countries, Lebanon lacks a national wastewater management strategy that can effectively protect public health and environmental quality. This has led the local communities and municipalities to plan and implement their own arrangements for wastewater treatment systems. However, most municipalities still lack the human and financial resources, management capabilities, and environmental awareness necessary to implement wastewater management in an environmentally sound manner.

Provision of safe domestic water for the promotion and protection of public health: a case study of the city of Beirut, Lebanon.

Securing adequate safe drinking water and proper sanitation is a major challenge facing the developing world. The "Water for Life Decade" emphasizes the importance of upgrading national water quality and sanitation services. This study assessed the domestic water profile in the city of Beirut.

Assessment of domestic water quality: case study, Beirut, Lebanon.

In urban cities, the environmental services are the responsibility of the public sector, where piped water supply is the norm for urban household. Likewise, in Beirut City (capital of Lebanon) official water authorities are the main supplier of domestic water through a network of piping system that leaks in many areas. Beirut City and its suburbs are overpopulated since it is the residence of 1/3 of the Lebanese citizens.

Variation of metals in bed sediments of Qaraaoun Reservoir, Lebanon.

The Qaraaoun Reservoir (impoundment of the River Litani) is the only artificial surface water body in the country, Lebanon. Earlier study on the water quality of the Qaraaoun Reservoir identified three water quality zoning with a central distinct zone suitable for multipurpose water usage. The objective of this study was to extend the earlier work by considering the total metal content of reservoir bed sediments and hence to evaluate factors that control metal deposition or capture.

Evaluation of water quality of the Qaraaoun Reservoir, Lebanon: suitability for multipurpose usage.

The increased demand on water resources in Lebanon as a result of: progressive urbanization, socio-economic growth, agricultural activities and development of industries is, according to the national authorities, a major critical factor by the year 2010. Political difficulties in earlier years imply a dearth of pertinent data. The objective of this study was to evaluate water quality of the Qaraaoun Reservoir of the Litani River and assess its feasibility for multi-purpose usage as one of the solutions to the aggravated water problems in Lebanon.

Transboundary movement of hazardous wastes into Lebanon: Part 1. The silent trade.

This paper discusses the transboundary movement of hazardous wastes into developing countries, frequently referred to as the "silent trade," and the new efforts by the Basel Convention to control the international movement of hazardous wastes. The importation of hazardous wastes into Lebanon is examined in terms of waste trade activities (e.g.

Transboundary movement of hazardous wastes into Lebanon: Part 2. Environmental impacts and the need for remedial actions.

This paper discusses the transboundary movement of hazardous wastes (the "silent trade") into Lebanon in terms of environmental impacts and remedial actions. It highlights the projected impacts on potable-water quality, the exposure of the groundwater aquifer, and the status of quality control programs. The public responses to these problems are presented and characterized in terms of mistrust and rejection.
