Abstract:

Plastic pollution is considered one of today’s main environmental problem and pollutants in natural environments. Polystyrene (PS), one of the representative plastics, is an environmental concern. However, an assessment of the transport of styrene oligomers (SOs) from land to ocean has yet to be performed. Here, we show that anthropogenic SOs, an indicator of PS contamination in the environment, can migrate from land to sea by runoff and weather events such as rain and typhoon. All samples of sand and seawater taken from the coastline of the Tokyo Bay were found to contain SOs such as styrene monomer (SM), styrene dimers (SD), and styrene trimer (ST), in which these concentration distribution was in the order of ST>SD>SM. In particular, the pollution of SOs along the Tokyo Bay was relatively severer than those in other regions. The Tokyo Bay seems be considered as transporting high SOs through weather events, i.e., rain and runoff, which can reflect a heavily populated area and various land-based SOs sources connected with estuary. These findings are of interest from both the extent of PS plastic pollution and the transportation of SOs. Our results suggest that SOs pollutants are originating from the land-based sources to be present in the ocean, and along coasts from the land.

Abstract:

Atlantic and Mediterranean warming-related diseases outbreaks and species shifts recently have been documented. Evaluated tools of short-term effects on the health or organisms resistance are necessary to assess and understand mechanisms affecting marine biodiversity. Until now, climate warming has been studied at the population or community level. Here we offer a better understanding of such phenomena at the individual organism level, using anatomic-morphological approaches to interpret effects of natural physical stressors, according to behavioral patterns. The goal of this work was to evaluate the sea anemones behavior with temperature variance. This study takes a method of behavioral observations (morphological and anatomic parameters, with physiological implications) to identify changes in behavior, after exposure to the physical stressors temperature (10, 15, 20, 25 and 30) on temperate sea anemone Actinia equina over 96 h of exposure. Other endpoints as condition index and reproduction also assessed. Behavioral patterns analysis placed the differentially ecological functions in a wide range of categories including tentacle flexion, tentacle retraction, column cavitation, peristome depression and oral disc flexion. These parameters suggest that the early stress response (before result on individual death) to elevated temperature involves essentially all aspects of same chemical reactions. In this case we observed receptors functioning and the frequency of open-close oral sea anemones, tentacles and columns anatomic alterations to detect earlier the effects of physical stress induction. The superiority of results tested was that the key species reacted to different temperature ranges in order to demonstrate that species from different climatic zones could have the same behavioral pattern but have intrinsic adaptations on each climatic zone. Also some collections of parameters such as: water nutrients availability, reproductions rate (number of polyps), survival (condition index) and temperature variations were significant on behavioral answers.

Abstract:

In organic chemistry, due to their many applications, derivatives of thiophene stand out among biomolecules used in trials to determine biological activity. They are present in natural products and are frequently incorporated into agrochemicals, dyes, and drugs in general. Various thiophene derivatives are produced by molecular modifications through varied synthesis routes that result in increases in specificity and thus safety profiles. Within the thiophenic family, the 2-amino-thiophenes have been well reported. In new drugs investigations they occupy a special position due to innovations in their synthesis (Gewald reaction), availability, stability, and structural simplicity that allow them to be important scaffolds in chemical and therapeutic products; like the top selling drugs olanzapine and tinoridine. In addition, they present a large spectrum of biological properties that include antimicrobial, anti-inflammatory antioxidant and antiplatelet activities. In the present work we demonstrated the uses of cyclohexane-1,3-dione and cyclohexane-1,4-dione for the synthesis of thiophene, pyrazole and pyran derivatives.

Abstract:

Statement of the Problem:

In the era of rapidly changing global environment, research attempts have been made to replace fossil fuels for the control of greenhouse gases emissions and environmental pollution. Ionic liquids (ILs) have received widespread attention as an eco-friendly reaction medium for various processes involved in industries. Due to their unique properties (negligible vapor pressure, non-flammability, excellent solubility, non-volatility, reusability, high thermal and electrochemical stability), ILs can be considered as safer and more sustainable alternative to volatile organic compounds (VOCs) used in industries. Experimental density, speeds of sound and their derived properties, excess molar volumes, V^E    data of ILs and their mixtures with organic solvents may be of great importance in mass and heat transfer processes of working fluids and thus can be utilized for designing and engineering of such processes.

 Methodology and theoretical orientation:

  The densities, ρ_ijk and speeds of sound, u_ijk data of ternary {1-butyl-3-methylimidazolium tetrafluoroborate (i) + 1-ethyl-3-methylimidazolium tetrafluoroborate (j) + cyclopentanone or cyclohexanone (k) mixtures have been measured at 293.15 K and 298.15 K using a digital densimeter and speed of sound analyser.  The  observed  ρijk  and uijk data  have  been  employed  to  determine  (VE )ijk  and   respectively. The (VE )ijk and    data have been fitted to Redlich-Kister equation  to see whether the observed data is of required accuracy to be utilized in various industrial processes or not ? The topology of the constituent molecules has been utilized (Graph theory) to obtain information about the state of the components in pure state and also regarding the various processes involved in the mixture formation.

 Conclusion and significance:

The (V^E )_ijk  and   data predicted by Graph theory compare well with their experimental data. Further the measured data are of required accuracy and can be utilized for designing various processes involving fluid in industries.

Abstract:

In the last few decades, humankind is facing water pollution and its scarcity. In this regards, great attention is being given to the removal of organic pollutants from wastewater by advanced oxidation processes (AOPs) that are based on generation of highly reactive species, especially hydroxyl radicals. Fenton processes are attractive alternatives in effluent treatment, especially when applied to recalcitrant compounds. Leather tannery wastewater treatment represents a difficult technological problem. Unfortunately, it is one of the most serious industries which generates large amounts of hazardous wastes and is a source of severe environmental impacts as well as health risks. In particular, the dehairing stage generates an alkaline wastewater (high pH) with high concentrations of organic matter, sulphides, suspended solids, and salts, which shows significant toxicity. Also, chrome has well known adverse effects because it is highly toxic, highly persistent in the environment and not biodegradable. Conventional treatment methods of this effluent are inefficient to meet the required limits. The objective of this work was to evaluate the efficiency Fenton's reaction as an advanced oxidation for the treatment of lime/de-hair and chrome effluents, investigating the reduction of COD, ammoniac nitrogen and chromium concentrations as well as toxicity in treated wastewaters. The different operational conditions as variable doses of hydrogen peroxide (H₂O₂) and iron sulfate (Fe²⁺), pH, time and different mass ratios of Fe²⁺/H₂O₂ were investigated to determine the optimum operating conditions for the elimination of chrome, chemical oxygen demand (COD), biological oxygen demand (BOD), sulfide, total kjeldahl nitrogen (TKN), total suspended solids (TSS) and oil & grease. The experimental results show that COD, sulphide and oil-grease was removed effectively and the treated effluent has a good quality. Residual concentrations of COD, BOD, TSS and chrome were 974, 533, 19 and 485 mg/l, respectively. The sulfides concentration was highly reduced from 3695 to 1.4 mg/l. The overall COD, sulphide, oil-grease and chrome removal efficiencies reached 82%, 90%, 96% and 95% respectively. The treated effluent could meet the national regulatory standard for discharge into the sewerage systems with respect to the studied parameters.

Abstract:

Following the dawn of the environmental epoch in Africa almost four decades ago, a plethora of studies have been conducted in the continent’s major urban centers to determine the effect of multiple sources of contamination and pollution of the air, water and soil environment, and how these are accentuated by climate change. Toxic metal contamination, organic pollution, smog, acid mine drainage (AMD), acid rain, greenhouse gas accumulation and release of teratogens (e.g. ionizing radiation) are the most widespread legacies of an often uncontrolled growth that has deeply changed the geochemical character of these urban environments. For the megacities of Cairo, Lagos and Kinshasa, we have assembled a mass of data on the migration pathways, uptake dynamics and health impacts on humans of geochemical emitted through mining and ore processing, burning of fossil fuels, industrial and manufacturing activities, human and industrial waste disposal practices, and vehicular traffic emissions. In this presentation, we examine the effect of climate change on these processes and activities. Finally, we illustrate the role of urban geochemistry in mitigating the damages, by systematizing and analysing the assembled data (such as the nature of soils, stratigraphy, groundwater flow and patterns of atmospheric circulation) for use in designing appropriate measures for clean-up and monitoring of the polluted areas.
