This study features an analysis of the influences and effects of different postures performed within tasks of waste collection. Four men, ages 30, 46, 60 and 65, and two women, ages 38 and 48, took part in this study. The assessment makes use of a 3D Static Strength Prediction Program (3DSSPP™) to...

Activated sludge is a biological floc composed of microorganisms, organics, and inorganics and plays an important role in wastewater treatment. The pH of an activated sludge suspension determines the acid – base behaviour and the charge of the microorganisms in water. In the present study, the...

The best method to treat seawater is known to be the use of reverse osmosis (RO) systems. The cost factor becomes the most important issue when using RO systems. Although quite costly, RO systems are essential systems for ships. As known very well, water is a critical resource on ships, especially...

This study examined the trends in anthropogenic chemical contaminants in groundwater samples in rural areas of Ebonyi State, South-eastern Nigeria. Groundwater samples were collected from Ezza North (a quarry mining area) and Ezza South (an agricultural/commercial area) and were analysed using...

Nitrate is a common groundwater pollutant all over the world. In some regions of Iran, its levels are high enough to cause serious problems to human health and the environment . The objectives of this work were to evaluate the efficiency of Fe-doped TiO 2 nanoparticles at removing nitrate from...

The present study has been carried out for the trans-boundary Subansiri sub-basin of Brahmaputra river basin. Subansiri is the largest tributary of Brahmaputra within India and the river system has its practical importance as it holds a high water resources as well as hydropower potential for the...

The carbonate and physicochemical characteristics of the surface microlayer and upper mixed layer of a tropical coastal lagoon were investigated. Data on the physicochemical parameters generally indicated a moderately polluted ecosystem. The influence of the ocean environment over the Lagoon system...

Proper Hospital healthcare Waste Management (HCWM) is imperative for ensuring public health and environmental protection. In this context, three Prefectural hospitals of Mytilene, Agrinio, and Messolonghi, were studied with respect to planning and management of infectious wastes, cost, training of...
