Persistent toxic substances including persistent organic pollutants and heavy metals have been released in high quantities surface waters by industrial activities. Their presence environmental compartments is causing harmful effects both on the environment human health. It was shown that their removal from wastewaters using conventional methods adsorbents not always a sustainable process. In this circumstance, use of microorganisms for uptake can be seen as being an environmentally-friendly...

The environmental pollution that occurs in direct response to the widespread use of man-made/conventional pesticides results from many chemicals require a long period time, often decades, degrade. synthetic nature also harms animals, beneficial insects, microorganisms, and plants, as well humans. Fortunately, however, there are natural pesticides, so-called biopesticides, effective against pests more importantly, do not interfere with well-being ecosystems. Consequently, most biopesticides...

Environmental threats posed in the environment by plastic production and wastes continue to be a major problem today, closely connected with increase of plastics consumption population.Moreover, little efforts are involved some parts world associated waste collection, recycling reuse.Considering all these prerequisites, identification discussion risks generated performed this paper measures for reduction were proposed.Although polymers not considered toxic, residual monomers contained...

The sorption of metal ions from aqueous solution plays an important role in water pollution control and recent years there has been considerable interest the use low-cost adsorbents.Many researchers have tried to exploit naturally occurring materials as adsorbents, for removing heavy metals.In this article removal performance various adsorbents derived agricultural waste or natural material is evaluated.The adsorption capacities low cost presented vary, depending on characteristics...

Emerging pollutants such as pharmaceutical active compounds were detected worldwide in different environmental compartments.Nowadays, multiple studies are focused on the investigation of their fate, well to find new, efficient and sustainable removal technologies.Several demonstrated that heterogeneous photocatalysis is one most promising techniques used for water purification.Thus, aim our work was evaluate photodegradation efficiency a refractory emergent compound, named clofibric acid,...

This study is focused on the assessment of risks caused by pesticide residues to Romanian and other European populations, modelling acute chronic considering short- long-term exposures in specific fruits vegetables from different regions. Data were obtained 2016 official monitoring programme. For assessing dietary risk, we used Pesticide Residue Intake model—PRIMo. According data, it was found that 50.44% fruit samples 28.25% vegetable contaminated with pesticides. Our (in a maximalist...

Bioplastics are biobased materials, usually easy biodegradable, derived from renewable resources.Evolution of bioplastics production is related to: bio starch and mixtures (74.5%); bioplastic products fermentation (13%), petrochemicals materials (12.5%).They seen as a viable solution to avoid some environmental impacts caused by the use fossil-based conventional plastics.In this context, general objectives study entail analysis selection optimal alternative able be used for packaging...

The practice of organic agriculture represents an essential requirement for conserving natural resources and providing the food necessary a growing population, on sustainable basis. Tomatoes are considered to be one most important crops worldwide. In this context, production tomatoes should taken into more consideration. use microorganisms-based commercial products is alternative chemical fertilizers. Anyway, results their still variable because various factors. aim study was test effect...

The potential of the model crop Brassica napus L. (rapeseed) for phytoremediation soils polluted with metals was investigated at laboratory scale. first step consists in evaluation seed germination and growth plant a controlled environment, followed by determination photosynthetic pigments content represented chlorophyll b carotenoids. degree metal accumulation rapeseed has been evaluated bioaccumulation factor (BAC), bioconcentration (BCF) translocation (TF). Phytotoxicity tests were...

Environmental contamination with heavy metals, especially of soils and water, became a significant problem because most them are toxic to the living organisms, non-degradable persistent in contaminated media. Physico-chemical methods, such as chemical precipitation, electrochemical treatment, filtration, ion exchange, evaporation, reverse osmosis membrane technologies currently used methods remove metal ions from wastewaters. Bioremediation technologies, which known be environmentally sound...

Abstract This study compares the capacity of Rhodotorula sp. and Bacillus megaterium for Cd(II) removal considering influence operating parameters (pH, biosorbent dosage, contact time, temperature, initial metal concentration in solution). The highest uptake 14.2 mg/g by was exhibited at 30°C, when working pH 6 with 5 g/l after 48 h time. In these conditions, a efficiency 85% obtained. Similar outcomes were obtained B. (15.1 mg/g, 90%) 35°C, 4 3 considered as optimum set parameters,...

This work demonstrates new evidence of the efficient destruction and mineralization an emergent organic pollutant using UV-A titanium nanosized catalysts. The target compound considered in this is primary metabolite a lipid regulator drug, clofibrate, identified many studies as refractory during conventional wastewater treatment. photocatalytic performance study was carried out batch mode at laboratory scale, aqueous suspension. Kinetic data showed that dioxide P25 Aeroxide® exhibits highest...

The individual physical, chemical, and biological interactions that determine the exposure of plants animals to chemicals associated with soils are great importance in assessment contaminants bioavailability.Understanding bioavailability processes is at last needed improve scientific basis risk purpose present research.Since embedded within existing human health ecological frameworks, sorption efficiency assumed as factor used an adjustment applied dose.Various (dyes, refractory organics,...

Given the current highest demand in history for raw materials, there is a growing recovery of key metals from secondary sources, order to prevent metal depletion and reduce risk toxic discharges into environment. This paper focuses on nature-based solutions (i.e., biomining bioleaching) applied resource (metals) solid matrices. Biomining exploits potential microorganisms facilitate extraction wide range waste materials as an interesting alternative, replacing primary with material resources...
