The use of cement and concrete to immobilise radioactive waste is complicated by the wideranging nature of inorganic cementing agents available as well as the range of service environments in which cement is used and the different functions expected of cement. For example, Portland cement based concretes are widely used as structural materials for construction of vaults and tunnels. These const...

Soil samples were collected from three different habitats at monthly intervals. Order Oribatida was the highest numerically abundant group of acrarines followed by order Mesostigmata. ANOVA indicated significant difference (p<0.05) in population density of oribatid mites among the sites. Five, eight and ten species of oribatid mites were recorded from the waste disposal site at Panga, Denguajha...

BACKGROUND Developing cities like Khulna, the third largest metropolitan city in Bangladesh, have now begun to confess the environmental and public health risks associated with uncontrolled dumping of solid wastes mainly due to the active participation of non-governmental organizations (NGOs) and community-based organizations (CBOs) in municipal solid waste (MSW) management. METHODS A survey ...

The sixth General Radioactive Waste Plan approved by the Spanish government in 2006, foresees important volumes of wastes with a very low content of radioactivity mainly coming from the dismantling of nuclear power plants, along with the occurrence of some radiological industrial incidents in the past. This fact has boosted the construction of a new disposal installation, specifically designed ...

Background: The field of medicine has improved by leaps & bounds. More & more critical patients are being treated by ever increasing number of hospitals. The need for sterility & infection control has lead to increased use of disposable consumables. Substantial waste generated is infectious and is a potential risk factor to the society if not properly disposed. This study was done with an aim t...

BACKGROUND Adequate management of healthcare waste (HCW) is a prerequisite for efficient delivery of healthcare services. In Nigeria, there are several constraints militating against proper management of HCW. This is raising some environmental concerns among stakeholders in the health sector. In this study, we analyzed the practices of HCW management and determinants of risky/safe indices of HC...

Since the world's first disposal of radioactive waste in Oak Ridge, Tennessee, in 1944, considerable experience has been acquired in the field. The first disposal site — intended for "actively contaminated broken glassware or materials not sufficiently clean to be used in other work" — was a simple trench filled with unconditioned waste located on the Oak Ridge site. Similar approaches were ado...

Aim: To determine the following among the final year students of the Lahore Medical & Dental College, Lahore: their knowledge & awareness regarding biomedical (BM) waste management policy and practices, their attitude towards biomedical waste management, and their awareness regarding needle-stick injury and its prevalence among different categories of health care providers. Methods: A cross-sec...
