Opis:
Air pollution arises mainly from automobiles and industries is well known fact. Monitoring and detection by instrument cannot be possible everywhere however, indication from plant species by their alterations in leaf morphology and anatomy may be a suitable easy screening measurement. The present study aims to detect morphological features with special reference to gall quantification and anatomy of leaves of Alstonia scholaris R. Br., found in eastern Indian urban and suburban area that are exposed to vehicular emission. The results indicated alterations of leaf morphology along with length (L), breadth (B), L/B ratio and significantly increased (P < 0.001, 0.01 and 0.05) Air Pollution Index (API). It is concluded that vehicular emission can be monitored as an early indication through increased API in A. scholaris. Further research would be needed in relation to secondary metabolites alteration, biochemical and genetic parameters to know pollutant susceptibility as an indicator. In addition, anatomical abnormalities in gall formation as well as numbers were also pronounced in leaves exposed to various load of air pollution.

Predictive toxicity and mutagenicity
Opis:
In globe, Pyllanthus niruri is a well-established medicinal herb studied by many researchers, grown widely in many parts of West Bengal. The present study was aimed to predict the acute toxicity as LC50 in Daphnia magna and Pimephales promelas and rat oral LD50 value as well as Ames mutagenicity by using QSAR modeling software, T.E.S.T. (Toxicity Estimation Software Tool) for commonly found phytochemicals in Pyllanthus niruri. In present works, the data were obtained for LC50, few phytochemicals were toxic to D. magna and P. promelas and also mutagenic but rat oral LD50 determined less toxic. The present QSAR modeling work is suggesting that more researches should be required through experimental as well as predictive study with other prescribed software to know the mechanisms of toxicity and mutagenicity for these combined form of phytochemicals after separating each natural chemical from extract prior to drugs development for therapeutic usage.
