This article contains information on EcoSAR. EcoSAR is the advanced airborne polar metric and single pass interferometric P-band SAR instruments under development at the NASA Goddard Space Flight Center, through NASA's instrument Incubator Program (IIP). EcoSar will provide two and three-dimensional fine scale measurements of terrestrial ecosystem structure and biomass onboard the NASA P3 aircraft. These measurements directly support science requirements for the study of the carbon cycle and its relationship to climate change. To evaluate plant growth on earth from an airborne platform, both c

Abstract:

Assessing the ecotoxicity of pharmaceuticals is of urgent need due to the recognition of their possible adverse effects on nontarget organisms in the aquatic environment. The reality of ecotoxicity data scarcity promotes the development and application of quantitative structure activity relationship (QSAR) models. In the present study, we aimed to clarify whether a QSAR model of ecotoxicity specifically for pharmaceuticals is needed considering that pharmaceuticals are a class of chemicals with complex structures, multiple functional groups, and reactive properties. To this end, we conducted a

Abstract:

Abstract ECOSAR (1998), a personal computer software program available from the U.S. Environmental Protection Agency (EPA) and affiliated vendors, is used to estimate the toxicity of chemicals to aquatic organisms, particularly fish, daphnid and algae species. It relies on approximately 150 equations, each for a chemical class of substances (Clements et al. 1996), which are linear correlations (SARs) of measured toxicity values of class-representative compounds with their octanol/water partition coefficients, with the latter taken from a database or computed by a companion program.

Abstract:

Abstract Amoxicillin can have adverse effects on non-target bacteria in aquatic environments, causing disruption to the balance of aquatic ecosystems and promoting the emergence of antibiotic resistance. The Advanced Oxidation Process, namely UV/H2O2, is a promising method for the degradation of antibiotics such as amoxicillin due to its effectiveness. However, the degradation products might have ecotoxic potential and have not been studied; therefore, this study aims to evaluate the ecotoxicity of amoxicillin degradation using UV/H2O2.

The best operational conditions for alachlor (0.33 mmol L-1) degradation were obtained by a 32 factorial design, in which the factors/levels were: NaCl concentration (0.05, 0.1, and 0.15 mol L-1) and current density (10, 30, and 50 mA cm-2).

Abstract:

The presence of pharmaceuticals in water is a problem of utmost importance due to the various adverse effects that these compounds may have on aquatic organisms and also humans. Since conventional wastewater treatment plants fail to efficiently remove many of these compounds, new techniques such as heterogeneous photocatalysis have been developed that are capable of degrading them. In this study, graphitic carbon nitride (g-C3N4) was used as photocatalyst to remove metronidazole (MTZ), which is a widely prescribed antibiotic that has been reported as a potential carcinogen. The experiments wer

Abstract:

Ecological sanitation (Ecosan) by-products are inherently limited in their potential use as excreta resources. Disgust behind human excreta and derivatives continues to challenge the further use of Ecosan-by products. Although treated excreta, including Ecosan by-products, have gradually been adopted worldwide, diverse perspectives among users hinder their use in agro-practices. This study explored perceptions of the use of Ecosan-by products as relates to the disgust of human excreta among rural farmers in Burera district, Rwanda.

Abstract:

Background: The utilization of “on-site excreta decomposition technology” known as “Ecological sanitation (Ecosan)” has a rational use of human excreta. It is a resource-oriented sanitation mostly feasible in areas with rocky soil and prone to agriculture. This technology was implemented in Rwanda for more than a decade. However, little is known about Ecosan utilization in the process of scale-up in the community. Aim: The study was carried out to determine enablers and barriers associated with the utilization of Ecosan in Burera district, Rwanda. Methods: A mixed method study was surveyed in

Abstract:

Fossa Alternas and double vault urine diverting dry (DVUDD) latrines have been extensively promoted as ecological sanitation (EcoSan) latrine options in Malawi, but little is known about whether they are used properly. A qualitative study of EcoSan users was conducted in Blantyre and Chikwawa districts, Malawi. Data were collected using in-depth interviews (IDIs). Twenty-eight (28) and seventeen (17) IDIs were conducted with household heads that had Fossa Alternas and DVUDD latrines, respectively. Recorded data were transcribed verbatim and analysed thematically. Of the total 45 EcoSan users,

Abstract:

The ecological risk assessment (ERA) of chemical substances is based on the premise that the protection of the most sensitive taxon safeguards the overall community. Given the severe scarcity of ecotoxicological data concerning groundwater species, we felt urged to consider epigean model species' sensitivity data to determine the safe pesticide concentrations for obligate groundwater dwelling species. To this end, we performed the ERA of pesticide mixtures occurring in eleven Mediterranean porous aquifers (Abruzzo region; central Italy). The evaluation was based on data collected between 2010

Abstract:

‘Lessons learnt on Ecosan in Morocco’ is a short analysis of experience gained in Morocco especially in rural areas where people do not have adequate systems of evacuation of their wastewater. The rural population cannot afford conventional sanitation systems. In response to this, we have thought to promote ecological sanitation that recognises wastewater not as a waste but as a resource. The first Urine-Diversion Dehydration Toilets (UDDTs) were introduced in a rural village called ‘Dayet Ifrah’ in Morocco in December 2009. Since then, households are starting to see the advantages of UDDTs an

Abstract:

The rough scad, Trachurus lathami Nichols, 1920, is a small pelagic species distributed along the West Atlantic coast. It is most abundant in the Southern Brazil (28°30'–34°S) and in the Southeastern Brazilian Bight (SEBB, 22°–28°30'S). The rough scad is fished by purse seines, which main target is the Brazilian sardine, Sardinella brasiliensis (Steindachner, 1879). Age and growth are vital to understand the life cycle of a species, to fishery management and ecosystem modeling. This study aimed to assess the age and growth of T. lathami, to identify its age structure in the SEBB, and to evalua

In upcoming 20 years, it is estimated that a surplus of 2 billion will get migrated to urban areas, probably in developing countries, necessitating sanitation. Still greater than 90% of sewage in developing countries is discharged unprocessed polluting water bodies.

Applying different rates of sludge to spinach and carrots resulted in an increase in bacterial and helminth ova counts in crops as the quantity of sludge increased. The helminth ova content in crops was always greater in leaves than in stems, with a content varying from 2 t

Quantitative microbiological risk assessment (QMRA) was done to determine health risks associated with use of EcoSan. Pathogens considered includedEscherichia coli (E. coli),Salmonella,and soil transmitted helminths (STHs). Exponential and Beta Poisson models were used to estimate the risk from helminthic and bacterial pathogens, respectively. Main exposure pathways were through poor storage of sludge, contaminatio

Particulate matter air pollution is one of the most dangerous pollutants nowadays and an indirect cause of numerous diseases. A number of these consequences could possibly be avoided if the right information about air pollution were available at a large number of locations, especially in urban areas. Unfortunately, this is not the case today. In the whole of Europe, there are just approximately 3000 automated measuring stations for PM10, and only about 1400 stations equipped for PM2.5 measurement.
