Water is a multi-dimensional issue and a prerequisite for achieving human security, from the individual to the international level. The Nile River has long been a crucial component of both the identity and the vitality of Egypt. Egypt faces a rapidly increasing deterioration of its surface and groundwater due to increasing discharges of heavily pol...

The construction industry has been considered an accident prone industry. Alarming statistics indicate that the construc-tion industry accounts for 55,000 fatal injuries each year. That is because construction sites are often filled with poten-tial hazards that can lead to serious injury or death. Responsibility for these injuries may be attributed...

Over recent years, safety has become a way of life for construction and industrial workers in the US. A new safety culture has emerged. In fact, the incidence rate for all recordable nonfatal injury and illness for construction workers has decreased from 13.1% in 1992 to 5.4% in 2007 (BLS, 2002)(BLS, 2008). This decline is due to standards set fort...

In 2006 a report on the analysis for lead in 80 new residential paints from four countries in Asia revealed high levels in three of the countries (China, India and Malaysia) and low levels in a fourth country (Singapore) where a lead in paint regulation was enforced. The authors warned of the possible export of lead-painted consumer products to the...

Background:Assessment of environmental, microbiological and immunological hazards among nickel electroplating worker shop was the goal of this study as electroplating processes result in the emission of soluble nickel compounds aerosoles causing health hazard .Materials and Methods:Study of 50 workers in a nickel electoplating work shop compared to...

Galvanization is the process of coating steel or cast iron pieces with zinc, allowing complete protection against corrosion. The ultimate goal of this work was to assess the effect of occupational exposure to zinc in the galvanization process on different metals in the human body and to detect the association between zinc exposure and its effect on...

Background: It was established that morbidity with temporary loss of working capacity due to diseases of the circulatory organs showed a tendency towards increase among workers of glass industry .This study was carried out at one of glass manufacturing companies in Egypt. It aims at investigating the association between cardiovascular manifestation...

Background: An estimated 4.9 million people were newly infected with HIV around the world in 2005. The proportion of women infected by HIV worldwide has grown steadily and it is estimated that half of the people currently infected by HIV are women. Significantly higher rates of HIV infection have been documented among populations involved with sex...

Background: Pickling is a process for the removal of a scale, oxides, or other impurities from a metal surface by immersion in an inorganic acid, usually sulfuric acid, hydrochloric acid, nitric, hydrofluoric, or phosphoric acid.
