Abstract:
... This study involves the utilisation of peanut husk for the removal of Drimarine Red HF-3D dye from aqueous solutions. Batch study experiments were conducted with native, HNO ₃-treated and Na-alginate-immobilised peanut husk biomass. Maximum dye removal (95.24 mg/g) was obtained with HNO ₃-treated biomass. The experimental data were successfully explained with a pseudo-second-order kinetic model fo ...

Abstract:
... Anthropogenic activities induce changes in a series of soil features. For example, continuous contact between soil and municipal solid waste leachates can encourage weathering processes as well as other mineral transformation reactions; consequently, the soil loses the function of environmental protection. Pollution-induced changes in the surface properties and morphology of soils have been rarely ...

Abstract:
... Rewalsar Lake, a mid-altitude, shallow and recreational water body located in the north-western Himalayas, Himachal Pradesh (India) was studied through monthly surveys in two consecutive years (March 2008 to February 2010). Forty-seven species belonging to seven groups of phytoplankton were identified from the lake. Microcystis aeruginosa and Synedra ulna exhibited a perennial habit. Ankistrodesmu ...

Abstract:
... In the northern Adriatic Sea, Mediterranean Sea, the mucilage phenomenon is usually related to the aggregation of extracellular organic matter of phytoplanktonic origin under special seasonal and trophic conditions. Environmental factors, such as temperature, salinity, nitrogen, phosphorus and N/P ratio as well as polysaccharide and monosaccharide levels in the presence and absence of mucilage wer ...

Abstract:
... The influence of energetic heterocyclic high-nitrogen salts on microbial activity in soil enrichment was investigated. 5-Aminotetrazole, a sodium salt of 5-aminotetrazole, ammonium azotetrazolate, sodium azotetrazolate, guanidinium azotetrazolate, triaminoguanidine azotetrazolate and triaminoguanidine hydrochloride were examined. Respiration tests determined the amount and rate of production of CO ...

Abstract:
... The Jiushanwai channel is located in the Lucheng district of Wenzhou City, China. Four aquatic plant species (Canna indica, Cyperus alternifolius, Myriophyllum verticillatum, and Lythrum salicaria) were planted on floating-beds constructed in a north-south layout along this channel. Five sites were sampled during spring, summer and autumn. The physiological characteristics (content of chlorophyll ...

Abstract:
... The potential translocation of heavy metals by Parthenium hysterophorus over 30 and 90 days and its effect on biomass, chlorophyll content and photosynthetic activity were studied on 0, 10, 25, 50 and 100% fly-ash-amended soil (FAS). The results showed a decrease in chlorophyll content and photosynthetic area on exposure to 50–100% FAS. Heavy metal reduction was in the order Pb>Cd>Zn>Fe>according ...

Abstract:
... Nanoparticles (NPs) contained in commercial products are released and enter into the aquatic ecosystem, posing serious possible risks to the environment and affecting the food chain. Therefore, investigating the potential toxicity of NPs on aquatic organisms has become an important issue. This study assessed the toxicity and trophic transfer of metal oxide NPs from marine microalgae (Cricosphaera ...
