We describe the use of catalytically self-propelled microjets (dubbed micromotors) for degrading organic pollutants in water via the Fenton oxidation process. The tubular micromotors are composed of rolled-up functional nanomembranes consisting of Fe/Pt bilayers. The micromotors contain double functionality within their architecture, i.e., the inner Pt for the self-propulsion and the outer Fe f...
In the study, multivariate statistical methods including factor, principal component and cluster analysis were applied to analyze surface water quality data sets obtained from Xiangjiang watershed, and generated during 7 years (1994-2000) monitoring of 12 parameters at 34 different profiles. Hierarchical cluster analysis grouped 34 sampling sites into three clusters, including relatively less p...
In the present study, heavy metal pollution and accumulation was investigated in an important mangrove plant, Avicennia officinalis grown in the polluted sites of Kanjurmarg creek, Mumbai. This creek is a location of discharge of influent and waste of some domestic industries. The analysis was done in leaves and stem of the plant as well as in water and soil for the heavy metals like Zinc ( Zn)...
In polluted environments, when microbial aerosols originate locally, species composition of the aerosols should reflect the polluted source. To test the connection between local environmental pollution and microbial aerosols near an urban waterfront, we characterized bacterial aerosols at Newtown Creek (NTC), a public waterway and Superfund site in a densely populated area of New York, NY, USA....
The efficacy of two rhizobacteria (Sphingobium fuliginis TIK1 and Sphingobium sp. IT4) of Phragmites australis for the sustainable treatment of water polluted with phenolic endocrine-disrupting chemicals (EDCs) was investigated. Strains TIK1 and IT4 have recently been isolated from Phragmites rhizosphere and shown to degrade various 4-alkylphenols-TIK1 via phenolic ring hydroxylation and meta-c...
Mussels maintained in sea water heavily polluted with domestic raw sewage have been found to harbor human enteroviruses.
Multivariate statistical techniques such as factor analysis (FA) and cluster analysis (CA) were applied for the evaluation of spatial variations and the interpretation of a large complex water quality data set of Chrompet in Chennai, Tamil Nadu. 11 parameters of water samples collected from 16 different sampling stations of city was determined. Factor analysis indicates three factors in pre mon...
Disease development in flounder (Platichthys flesus) was studied over a period of 3 years in three large mesocosms (40 m x 40 m x 3 m). Two of the mesocosms contained clean sand and the third, sharing a common water circulation with one of the clean-sand mesocosms, was stocked with contaminated dredged spoil. In this way, one of the clean-sand mesocosms was indirectly polluted via the water pha...
