RECENT DEVELOPMENTS IN METAL BASED PHOTOCATALYSTS – A REVIEW
The problem of fresh water scarcity is growing all around the world due to the over utilization and pollution. Discharge of pollutants especially dye bearing wastewater drastically affects the life of flora and fauna. Finding a suitable technology for the treatment of wastewater is highly warranted in the present context. Photocatalytic degradation using metal and metal oxide composite has lot of advantages like negligible by-products, simple to operate and economically very cheap. This manuscript reviews the potential photocatalytic applications of Ti, V, Mn, Co, Cu, Zn, Ga, Zr, Pd, Sn and inner transition metal doped catalysts.
QUALITY ASSESSMENT OF DRINKING WATER WITH REFERENCE TO HEAVY METALS IN MORENA CITY, MADHYA PRADESH, INDIA
Heavy metals in drinking water cause a serious threat to human health. Urban population is exposed to heavy metals primarily through water consumption and some heavy metals can bio accumulates in the human body and may induce cancer and other risks. The general objective of the study is to analyze the heavy metals in drinking water. The results revealed that Pb, Fe, Zn, and Asare present in the drinking water of Morena and may cause health risks to the residents. According to the indices, the city drinking water quality is good in terms of heavy metals.Continuous monitoring of drinking water quality is essential in terms of heavy metals and toxic substances.
DI-ISONONYL PHTHALATE (DINP) AND DI-(2-ETHYLHEXYL)-PHTHALATE (DEHP) DISRUPTS ENDOCRINE FUNCTIONS IN THE FRESHWATER FISH, OREOCHROMIS MOSSAMBICUS (PETERS, 1852)
Endocrine disrupting effects of two phthalate plasticizers namely di-isononyl-phthalate (DINP) and di-(2-ethylhexyl)-phthalate (DEHP) were evaluated in the freshwater fish, Oreochromis mossambicus. Male and female fishes were grouped separately and exposed to sublethal concentration of DINP (300 ppm) and DEHP (60 ppm) for 4, 7, 14, 30 and 60 days. At the end of every exposure period, blood serum was collected to determine the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid stimulating hormone (TSH), cortisol, testosterone and estradiol, and was compared with the respective control groups. The main findings of the study indicated that the levels of FSH and LH initially increased significantly (P<0.05) after the phthalates exposure, and decreased after 7 days onwards in both male and female fishes when compared to the corresponding control groups. DINP and DEHP treatment caused significant (P<0.05) decrease in the levels of TSH, cortisol and testosterone in time-dependent manner whereas the level of estradiol showed significant (P<0.05) reduction after 14 days of exposure in female fish without any significant changes in the male fish. The results suggest that exposure to phthalate plasticizers disrupts the hypothalamo-pituitary endocrine functions and this could be related to abnormal reproductive functions in the fish.
POLLINIA MORPHOLOGY OF SOME PLANTS OF ASCLEPIADACEAE IN LOWER COASTAL PLAIN OF WEST BENGAL: A SYSTEMATIC APPROACH
The morphological diversity of pollinia of 8 plants belong to Asclepiadaceae were examined under LM in corresponds to their size (length, breadth), shape of pollinia sac, translator and corpusculum as well as colour and translator attachment to the pollinia sac. The investigated plants were Calotropis gigantea(L.) Dryand, Calotropis procera (Aiton) W. T. Aiton, Dregea volubilis (L.f.) Benth. Ex Hook. f., Gymnema sylvestreR. Br., Hemidesmus indicus (L.) R.Br., Hoya obscura (Major), Pergularia daemia(Forssk.) Chiov., Tylophora indica R.Br. Out of the 8 plants there are largest pollinia sac (length-1485µm, breadth-576 µm), translator (length-408, breadth-74), corpusculum( length-594, breadth-259) in Calotropis gigantea and smallest pollinia sac (length- 153 µm, breadth- 77 µm), translator (length-79 µm, breadth-23 µm), corpusculum ( length- 109 µm, breadth-55 µm ) in Gymnema sylvestris. As a unit of flower Pollinia as well as pollen are an important tool to arrange and identify plant taxa.
INVASIVE ALIEN PLANTS: A THREAT TO THE TRADITIONALLY CONSERVED BIODIVERSITY OF THE SACRED GROVES OF BANKURA DISTRICT, WEST BENGAL, INDIA
Invasive alien species (IAS) are marked as the second largest cause of biodiversity loss in the world. On the other hand, sacred groves (SGs) are the traditionally conserved forest pockets, maintained by indigenous people, serve as the in-situ conservation sites for local biodiversity. This paper highlights the diversity and status of the IAS in 5 sacred groves of Bankura district, West Bengal. This type of study was never done before in West Bengal, which focuses only on the invasive flora of the sacred groves. In this study we have found 27 invasive alien plants under 26 genera, belonging to 17 families of dicot angiosperms. Out of the 27 plant species, most of them (20 sp.,74%) are herbs. Moreover, maximum number (8 sp.) of the plants belong to the family Asteraceae. The major effects of the IAS are also mentioned. The nativity of the IAS were recorded and the ‘Tropical America’ is found to be the native place of maximum number of invasive plants (15 sp.), whereas Parthenium hysterophorus and Croton bonplandianum (F = 100%) are the most frequent species. The Sonamela Bograsini Than (Sl.-3) possesses maximum number of invasive plants (17 sp.), whereas Kadmaghati Maa Khayraburir Than (Sl.-1) has the least number (7 sp.). Moreover, the areas of the SGs are negatively correlated (r= -0.967) to the number of IAS found in that sacred grove, that means the small sacred groves are in more threat of invasion. Along with IAS, the other threats to the sacred groves are also mentioned and the authors recommend to imply proper control methods for the IAS and a strict government policy on the maintenance of the sacred groves.
CORRELATION ANALYSIS BETWEEN LONGEVITY OF ADULT MOTHS AND ECONOMIC TRAITS IN FEW PURE RACES OF MULTIVOLTINE SILKWORM BOMBYX MORI (L)
In silkworm breeding, numerous traits are considered as important for improving them to increase the benefits to silk producers. An attempt was made to correlate the lifespan of adult stage of silkworm Bombyx mori multivoltine races with the few yield parameters are found to be significant in deciding the next generation yield. The adult life span was correlated with larval weight, cocoon weight, shell weight, shell percentage and filament length in the six multivoltines. Based on the Pearson correlation co-efficient estimations, there is correlation between adult longevity and larval weight. There is strong correlation between adult longevity and three cocoon characters namely cocoon weight, shell weight and shell percentage. Insignificant correlations were observed among six races selected between adult life span and filament length. But the R2 values are on the lower side in the multivoltine. Three groups were identified among six multivoltines from the correlation studies. I group involves pre and npnd races with less R2 values where as II group includes C.nichi, Nistari and PM with moderate R2 values. However, Daizo race recorded highest R2 values. The results obtained in the present studies clearly demonstrates that there is significant correlation between adult longevity and four economic traits, larval weight, cocoon weight, shell weight, shell percentage. However for the trait filament length such correlation could be possible only among selected breeds/hybrids.
PHYTOCHEMICAL AND PROXIMATE ANALYSIS OF SEED OF BAUHINIA RACEMOSA LAM
Bauhinia racemosa Lam. belongs to Family Fabaceae. It is a small tree commonly known as Apta which is found in India, Ceylon, and China. The Bauhinia racemosa Lam. is popular in India as tribal pulses. Roasted seeds are eaten by tribal people. The aim of the present study is to carry out the phytochemical study of immature seeds while proximate analysis of immature and mature seeds. Ash value was determined by the method of AOAC (1990). Crude fat, crude fiber contents were accomplished by a method of Sadasivam and Manickam (1992). Moisture content (69.5 ± 0.5 %) and crude fibre content (5.4 ± 0.31%) of the seed was higher in the immature stage. Powder behavior revealed the presence of alkaloid, tannin, cysteine, anthraquinone glycoside, xanthoprotein; steroids etc. The results obtained show the study is helpful for identification and authentication. Proximate analysis determining the nutritional value of seeds of B. racemosa Lam.
