Study of ultrasound-assisted sequential extraction procedure for potentially toxic element content of soils and sediments. Contaminated dredged sediments are usually fine texture, and some are low nutrient content or high salinity [, Bioleaching is the application of acidophilic microorganisms capable of Fe/S oxidative metabolism to promote metal dissolution in solid substrates, which is normally conducted as a sediment/soil slurry bioreactor [, S/S technology is used to immobilize contaminants both physically and chemically, which is evidently the most suitable for treatment of metal wastes [, OPC is a hydraulic binder mainly comprised of alite, belite, aluminate, and ferrite [, When OPC blends with supplementary cementitious materials (e.g., fly ash, kiln dust, or silica fume), they would have pozzolanic reactions during hydration. However, there are a number of issues associated with the use of planting that raise questions on public and private lands, including cost, quality of genetic stock, and the speed with which restored habitat can be obtained. JSTOR is a digital library for scholars, researchers, and students. Despite being less than 10% of the world's landmass, rainforests are unequivocally at the heart of the battle against climate change. Beneficial use of dredged sediment as a sustainable practice forrestoring coastal marsh habitat. For a period of two to three years, the site is monitored, watered, and weeded, to give the nascent forest every chance to establish itself. But despite their critical roles in sustaining life and slowing climate change, nearly all are at risk. 195, No. Never in the history of the evolution of the world has one species driven a mass extinction; without reversing course, we will surely seal our own fate of extinction.. 15 (1 August 2016), pp. 4, No. Yi, Y.M.

Deforestation takes place to turn forests into agricultural land for the production of commodities like palm oil and cattle, for mining, or to make way for new infrastructures like roads and dams. The true challenge is if the willingness to overcome greed and commit to our collective survival is great enough and swift enough to course correct in time. US, Get updates on exponential tech and culture. 2010; Rands et al.
