In addition to the largest existing expanse of tropical forests, Brazilian Amazon has among area mangroves in world. While recognized as important global carbon sinks that, when disturbed, are significant sources greenhouse gases, no studies have quantified stocks these vast mangrove forests. this paper, we total ecosystem and salt marshes east mouth River, Brazil. Mean were 257 Mg C ha −1 while those ranged from 361 746 . Although aboveground mass was high relative many other forests (145...
Abstract Surface mining is inherently linked to climate change, but more precise monitoring of carbon dioxide (CO 2 ) emissions necessary. Here we combined the geolocation mine sites and stock datasets show that if all legal active in Brazil are exploited over next decades, 2.55 Gt CO equivalent eq) will be emitted due loss vegetation (0.87 soil (1.68 eq). To offset these emissions, propose constructing soils (Technosols) from other wastes for reclamation. We this strategy could potentially...
Technosols created to reclaim degraded soils is a promising solution that needs further research. The objectives of the study were: i) create Technosol with very high capacity immobilize copper from mining, ii) assess after planting two tropical native tree species, and iii) analyse trees for extracting polluted soils. Myracrodruon urundeuva (aroeira) Cedrela fissilis (pink cedar) were planted in pots spiked at concentrations 125, 1525 3050 mg Cu kg−1. Height stem diameter measured over 90...
This study was based on the premise that Technosols constructed under tropical conditions are a valuable tool for inexpensive mine reclamation programs. These anthropogenic soils still poorly studied in Brazil and not recognized by Brazilian Soil Classification System. Given importance of mining to economy (the sector accounts 20% all products exported 5% gross domestic product), there is an urgency properly manage large amount waste produced. For this purpose, we suggest use as strategy...
Abstract The behavior of LAS (linear alkylbenzene sulfonate) in different environmental compartments was studied through wastewater treatment process steps sewage plants Alicante and Benidorm (activated sludge type) as well Guardamar (lagoons). fate LAS, using a specific HPLC method, monitored during compostage soil amendment operations. Finally, the marine sediments close to submarine sewer outfall were analyzed. results show significant differences between distribution homologs water...
Consistent vapor−liquid (VLE) and vapor−liquid−liquid equilibrium (VLLE) data for the ternary system water + ethanol isooctane (2,2,4-trimethylpentane) are reported at 101.3 kPa temperatures in range of 341−352 K. An all-glass, dynamic recirculating still equipped with an ultrasonic homogenizer has been used determination VLLE. The experimental obtained demonstrates existence a heterogeneous azeotrope 68.7 °C composition 0.198, 0.436, 0.366 mole fractions water, ethanol, isooctane,...
Abstract Mangroves are coastal hotspots for carbon storage and yet face multiple threats from anthropogenic activities. Here we explore the role of iron-mediated organomineral interactions (FeOMIs) in soil organic (SOC) stabilization their sensitivity to land use change (LUC) Amazonian mangroves. We show that Fe oxides protect more labile SOC fractions, which would otherwise be vulnerable biological degradation, with poorly crystalline being most effective phase retention. Despite fragile...
Due to the limited number of studies on phytoremediation using native tree species in tropical soils, aim was identify new phytoremediator from climate with purpose promoting an increase diversity trees used projects. Seven Brazil were selected: Cedrela fissilis, Handroanthus serratifolius, Copaifera langsdorffii, Hymenaea courbaril, Mimosa caesalpiniifolia, Cecropia sp. and Myracrodruon urundeuva. Seedlings these planted pots unpolluted Arenosol, then spiked 60, 100 500 mg kg−1 Cu. Height...

ABSTRACT Brazil faces urgent environmental challenges due to large waste production from mining and construction activities particularly regarding the disposal management of solid generated by these activities. The extraction iron ore storage tailings in dams, most which are at imminent risk rupture, represent foretold disasters. Additionally, raises concerns decreasing vailability inert landfill space. To address challenges, we evaluated potential Technosols made demolition (CDW) tailing...
