An environmental risk assessment for a DDX-contaminated agricultural area in Turkey: soil vs. plant or human vs. animal.

This study is the first research attempt to assess the environmental risks of an agricultural area contaminated with the p,p'-DDT and its metabolites (DDX) on human and terrestrial species through exposure to soil and agricultural products, simultaneously. The study was carried out for a DDX-contaminated agricultural area in Turkey. Soil samples obtained in two different harvest applications were analyzed in terms of DDX levels.

A mixed integer linear programming model for long-term planning of municipal solid waste management systems: Against restricted mass balances.

Long-term planning of municipal solid waste management systems is a complex decision making problem which includes a large number of decision layers. Since all different waste treatment and disposal processes will show different responses to each municipal solid waste component, it is necessary to separately evaluate all waste components for all processes. This obligation creates an obstacle in the programming of mass balances for long-term planning of municipal solid waste management systems.

Spinal Epidural Venous Angioma Presenting Symtomps of Lumbar Disc Herniation: A Case Report.

Spinal epidural venous angiomas are extremely rare. We report the case of a 60-year-old man who presented with disc herniation symptoms, complaining of pain in his left leg and numbness, especially at the base of the knee. On physical examination, the Lasègue test was positive at 45 degrees on the left side and no neurological deficit was detected on the lower extremity.

PCDD/F contamination on surface soil in the vicinity of a hazardous waste incinerator: is it possible a different trend?

This study is the first to investigate the contamination of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) on surface soils in the vicinity of the first hazardous waste incinerator of Turkey. In the study, 24 soil samples were taken from a 1625-m-radius circle whose center is the stack of the incinerator. This process was repeated 1 year later.
