this fertility experiment was carried out using split plots based on a randomized complete block design of three replications in 2006 at sari agricultural sciences and natural resources university. the aim of the experiment was to investigate some macronutrient and micronutrient accumulation in leaves of different soybean cultivars as influenced by some organic fertilizer types and levels. main...

The plasma gasification process has been demonstrated in many of the most recent studies as one of the most effective and environmentally friendly methods for solid waste treatment and energy utilization. This method is applied here to the treatment of sewage sludge. Results are presented for a case study concerning the Athens’ Central Wastewater Treatment Plant, at Psittalia Island. An integra...

Particle-associated pollutants (totaling 10(7) metric tons per year) are introduced into the New York Bight by ocean dumping, estuarine discharge, sewage outfalls, eolian transport, and shipping waste and spillage. Oceanic and estuarine circulation processes dilute and transport the particles by a natural dispersal system that also tends to be highly distributive; particle-associated pollutants...

sewage sludge with having the organic matter is considered as a source of micro and macro elements. in order to investigate the effect of different levels and period of application of sewage sludge (ss) on organic matter, respiration, and acid and alkaline phosphatase activity, factorial design were studied, in 3 replications. sewage sludge at five levels, (20 and 40 tons of sewage sludge, 20 a...

It is generally presumed that penetrating injuries of the orbit are associated with direct optic nerve injury. The incidence of TON after craniofacial trauma has been reported to be 0.5-1.5 % in older series. However, recent surveys report a higher figure; 2-5 % . This increased incidence may represent the diagnosis of subtle forms of TON closer to the time of injury. These types of cases appea...

During the Persian Gulf war in 1991 around eight million barrels of crude oil were spilled into water. This caused a large volume of contaminated water has to move to land in particular, Khuzestan's soil. A real danger of oil pollution would be an environmental calamity, and therefore, reclamation practice on the spoil soil area to expel the oil is essential. Bioremediation methods will be surv...

Problem statement: The chemical pollution of soil has become a major source of concern and has posed serious health problems within the last few years in many developed nations. A variety of organic and inorganic pollutants, including heavy metals, are being mixed in with the cultivated soil and water. Sewage sludge was one of the major sources of enrichment of heavy metals. These pollutants ar...
