Green synthesis of nanoparticles makes use of environmental friendly, non-toxic and safe reagents. In this study, we synthesised CoFe2O4 in a green approach, using leaf extract of Chenopodium album. The structure of the synthesised sample were analyzed by X-ray diffraction methods. The synthesised Photocatalyst was applied for photo degradation of methy orange as a reliable model pollutant. The...

S-Metolachlor is a promising alternative to metolachlor; however, there are concerns about its environmental fate following soil application. The present study was conducted to investigate the effects of several environmental factors on the degradation rate of S-metolachlor in soil. The rate of S-metolachlor degradation in soil under different conditions was determined by extracting and detecti...

Concerns about global warming, degradation of fragile ecosystems, and environmental and societal collapse have increased interest for lessons and/or solutions for today's environmental issues. Popular writers have turned to a classic degradation thesis of deforestation and presumed desertification within the Eastern Mediterranean as a cautionary tale of how past societies have committed ecologi...

This paper advances two hypotheses. First, the extent of an environmentally degrading economic activity is a function of the balance of power between the winners, who derive net benefits from the activity, and the losers, who bear net costs. Second, greater inequalities of power and wealth lead, all else equal, to more environmental degradation. “We can't see how the authorities can say they de...

The present paper examined the relationship of population to the environment and with growing population, poverty and urbanization the environment is degrading. Conducted an analysis of changes and trends over last fifty years. The study reveals that the country's population growth is imposing an increasing burden on the country's limited and continually degrading natural resource base. The nat...

Prediction of the fate of pesticides in soil is of interest from an environmental (pollution) as well as an agricultural (efficacy, carryover) viewpoint. Two environmental parameters that control microbial degradation of pesticides in soil are moisture and temperature. This study was designed to quantify the impact of soil water content and temperature on microbial degradation rates of the inse...

This paper examines the resultant impact of environmental degradation on the temporal dynamics in between 2001 and 2006. Data for the study are from both primary and secondary sources. The primary source is the survey of selected settlements and heads of households in which a questionnaire was administered. A multi technique was employed in the selection of sample. This involves a systematic ra...
