introduction due to the proximity to the sea, beaches always attracted tourists. on the other hand the coastal ecosystems are the most important and sensitive dual nature (land, naval), and variety of animal species are within themselves. the most important (and also longest) coastal area in iran are persian gulf and gulf of oman in south with about 2530km long and caspian sea in north with abo...

a new, local agro-industrial waste was valorized by chemical treatment and tested for its ability to remove cationic dye from aqueous solution. tendu (diospyros melanoxylon) leaves refuse, a solid waste from bidi industry which caused disposal problem, was studied as a biosorbent. raw tendu waste (tlr), along with sulfuric acid carbonized tendu waste (tlr-cm) and tendu waste treated with dilute...

Most of the tertiary care hospitals use radioisotopes for diagnostic and therapeutic applications. Safe disposal of the radioactive waste is a vital component of the overall management of the hospital waste. An important objective in radioactive waste management is to ensure that the radiation exposure to an individual (Public, Radiation worker, Patient) and the environment does not exceed the ...

Laboratory scale studies were conducted to investigate the feasibility of Industrial by-products as potential alternative medium to conventional gravel in the drainage layer of leachate collection system as permeable reactive barriers (PRBs) for landfill leachate treatment. Industrial by-products were used to treat effectively the landfill leachate, which is an innovative in-situ remediation te...

As the premier material in construction industry across the world, concrete has major role in the effects of construction to our environment. Consumption of concrete is very high due to extensive use of concrete in many structural applications. The rapid infrastructural growth in developing countries and production of many by-product as waste material making high role to concrete producers in i...

By analogy with natural ecosystems, an industrial ecology system, in addition to minimizing waste production in processes, would maximize the economical use of waste materials and of products at the ends of their lives as inputs to other processes and industries. This possibility can be made real only if a number of potential problems can be solved. These include the design of wastes along with...

Nuclear power provides a significant portion of our current energy demand and is likely to become more wide spread with growing world population. However, the radioactive waste generated in these power plants must be stored for around 60 years in underwater storage pools before permanent disposal. These underwater storage environments must be carefully monitored and controlled to avoid an envir...

in vietnam, municipal solid waste (msw) has being become increasing complex due to variety of reasons as the increasing quantity, changing composition of msw, rising public awareness and municipal administration policies among different cities and surrounding communities. there is not currently an efficient management system in place for facilities such as storage, collection, transfer, transpo...

Objective: To assess the biomedical waste management system in two major tertiary care hospitals and to look for the alternative measures which are costeffective and reliable. Study design: A comparative study Place and duration: The study was conducted at two tertiary care teaching hospitals of Rawalpindi and Islamabad city from 27 th April 2014 to 16 th May 2014. Methodology: The data was col...
