Abstract: Vegetables are an excellent source of most of nutrients and essential source of vitamins and minerals that play a vital role in ameliorating food deficit and overcoming nutritional problem.The present study was carried out to assess minerals and heavy metals content of some non-conventional wild vegetables, commonly edible vegetables from fresh water cultivated unknown sources and waste water irrigated vegetables available in Dhaka city, Bangladesh. In total of 16 vegetables samples were analyzed by using standard analytical methods of AOAC (2005), atomic absorption spectrophotometer, UV spectrophotometer and flame emission spectrophotometer.

Abstract: Elephant foot yam or Amorphophallus paeoniifolius is a tuber having extensive curative and digestive properties which belongs to the family Araceae, cultivated in western and southern states of India. Scientific evidence has suggested that elephant foot yam has high amount of dietary fiber, starch, carbohydrate, protein, and minute amounts of sugars. It also has significant amount of calcium and adequate amounts of sodium, potassium and vitamin C. The study of elephant foot yam becomes very significant as it has several medicinal benefits and is widely used in Indian medicine including Ayurveda. It has been found to contain anti-diabetic, analgesic, anti-bacterial, antifungal, anthelmintic properties , besides it has also found to have anticancerous properties. The corm is prescribed in bronchitis, asthma, abdominal pain, dysentery, splenomegaly, piles, elephantiasis, rheumatic swellings.

Abstract: Manzalah Lake is still the largest coastal lake in Egypt; it is situated along the Mediterranean Sea coast between the Damietta branch of River Nile in the west and Suez Canal in the east. It receives daily enormous quantities of industrial and agricultural wastes from different sources of drainage water from Bahr el-Bakar, Hados, Ramses and El Sirew drains. Samples of Oreochromis niloticus were seasonally collected from different areas namely; Ginka, Beshtier and Deshdy. The present work investigates the effect of the environment fluctuations and different pollutants that cause the abnormality in blood picture, hemolysis, deformed and damage of erythrocytes in the peripheral blood and leucocyte cells. The study revealed that Deshdy station was less polluted than the other two studied stations, Beshtier and Ginka.

Abstract: Municipal Solid Waste management is becoming a critical problem in most of the megacities of the world as waste volume continues to rise, which leads to the loss of resources and increased environmental risks. Municipal Solid Waste consists of more than 40 percent of organic waste, so composting most of this waste would be the best way to reduce the quantity to one fourth resulting in nutrient rich soil amendment. Composting is an age old practice for the biological conversion of organic waste to humus like substance which can enhance physical, chemical and biological soil properties. For the assurance of an effective solid waste management, implementations of appropriate solid waste treatment strategies are vital. This can be enhanced through the utilization of technologies that are most economically efficient, sustainable and ecofriendly.
