Biomonitoring of airborne metals in urban environments: new tracers of vehicle emission, in place of lead

Samples of Quercus ilex leaves and of the inhalable fraction of atmospheric particulate (PM(10)) were collected along a busy road and in a park in Florence (Italy). Quantitative comparisons and correlations of element concentrations in PM(10) collected by air samplers at two sites showed that Ba, Cu, Fe, Mn, Pb and Zn were the main metal pollutants emitted by vehicles in Florence. Very similar results were obtained by the analysis of Q. ilex leaves which were found to accumulate airborne metals as a function of the exposure time (i.e. their age). One-year-old leaves showed the highest rate of metal accumulation. Our results show that the progressive phasing-out of leaded petrol in Italy has resulted in a decrease of about 20% per year in the Pb concentrations in PM(10). Both PM(10) and Q. ilex analysis singled out Ba and Zn as valid tracers of automotive traffic instead of Pb.     

Particulate matter bio-monitoring through magnetic properties of an Indo-Burma hotspot region

Present study aimed to investigate the bio-monitoring study of particulate matter (PM) pollutants of 12 roadside plant species, in Aizawl, Mizoram, India (an Indo-Burma hot spot region). While, the second part was ascribed to the bio-magnetic monitoring stidies. Pertaining to first part of study, highest dust deposition was noted for Ramrikawn (RKN-Med) site on Ficus bengalensis (1.2?mg?cm^?2) and lowest in Bauhinia variegate (0.8?mg?cm^?2). Further, increased concentration of heavy metals (Fe, Cu and Zn) was recorded at RKN-Med site. Roadside plant leaves of F. bengalensis recorded maximum accumulation of Fe (26.1?mg?kg^?1) and Cu (19.5?mg?kg^?1) while Cassia auriculata (12.1?mg?kg^?1) showed lowest accumulation of Fe. B. variegate (1.88?mg?kg^?1) recorded lowest accumulation of Cu. Zn was recorded maximum (48.2?mg?kg^?1) in Mangifera indica while B. variegate showed lowest accumulation of 11.3?mg?kg^?1 Cu at Ramrikawn site. In relation to second part of the study, M. indica, Ficus benghalensis, Psidium guajava and Artocarpus heterophyllus were found to be efficient in bio-magnetic monitoring because all the magnetic properties (magnetic susceptibility, anhysteretic remanent magnetisation and isothermal remanent magnetisation) were high and significantly correlated with ambient PM (R²?=?0.424 to R²?=?0.998) thus may act as proxy for ambient PM.

Investigation of pH-Sensitive Swelling and Curcumin Release Behavior of Chitglc Hydrogel

Hydrogels are in use for encapsulation of curcumin for possible use in wound healing. Encapsulation helps in targeted delivery and enhanced activity of curcumin. We report here a pH sensitive hydrogel developed from chitosan. The hydrogel was prepared by reaction of chitosan and d-glucose, facilitated by the reducing agent Na-cyanoborohydride. The maximum yield of the hydrogel was obtained at pH 4.5 with the amount of chitosan, d-glucose and Na-cyanoborohydride as 0.3, 2.0 and 2.0 g respectively. A maximum curcumin loading efficiency of 74% was observed with curcumin amount in the feed at 0.15 g. The release study revealed a sustained release pattern over a period of 80 h with an initial burst release. Curcumin loaded hydrogel showed mild antibacterial activity against Proteus mirabilis and Enterobacter aerogenes.
