Contribution to the knowledge of Teloganodidae (Ephemeroptera, Ephemerelloidea) of India.

Two new species of Dudgeodes Sartori, 2008 and a new species of Teloganodes Eaton, 1882 are described from India; they are Dudgeodesselvakumari Martynov & Palatov, sp. nov. from Himalayan region (Uttarakhand), Dudgeodesmolinerii Sivaruban, Martynov, Srinivasan, Barathy & Isack, sp. nov., and Teloganodesbarathyae Sivaruban, Martynov, Srinivasan & Isack, sp. nov. from the Tamil Nadu part of the Western Ghats. Thus, for now, the Teloganodidae fauna of India includes 11 species. Dudgeodesselvakumari sp. nov. appears to be significantly extend northward the known distribution of Dudgeodes. Partial COI sequences were used as an initial clustering method to show the relationships of D.selvakumari sp. nov. with other sequenced operational taxonomic units (OTU) of the genus

A DETAL STUDY ON DRINKING WATER QUALITY AND DENTAL FLUOROSIS IN MELUR

In this study groundwater quality with reference to fluoride and other chemical parameters such as pH, total alkalinity, hardness, calcium and salinity was tested in Samples collected from Melur, a dental fluorosis prone area. Nineteen water samples from various sources viz., well, bore well and hand pump collected in different sites of the study area were examined. The study reveals that all the parameters except salinity are within standard limits in municipal water. Six ground water samples were found to have high fluoride levels above the Indian standard for potable water (1.0 mg/l). The study shows that elevated fluoride level is associated with lowering of hardness and calcium levels in water. The present investigation suggests that people of Melur should be advised to consume only municipal water. Ground water can be used for potable purpose only after its treatment for fluoride. Awareness on the consequences of excessive fluoride intake and its preventive Strategies must be given

EFFECT OF PHENOLIC COMPOUND DRUGS ONCERTAIN METABOLITES OF LIVER IN OREOCHROMIS MOSSAMBICUS

Some common analgesic and antipyretic drugs are known to be phenolic compounds. Examples are calpol, metacin and coSavil which contain paracetamol. Liver as the detoxifying organ is known to degrade any phenolic drugs that are orally administered. Such degradative intermediates, sometimes even have carcinogenic effect. In the present study, two paracetamol drugs, calpol and flexam (the later containing an additional phenolic derivative) were orally fed to Oreochromis mossambicus on long term basis. Free amino acids, proteins, lipids in the liver have been estimated. The accumulation of phenolic compounds has not been studied as such analysis demands finer sensitive techniques. Only the possible side effects of the drugs are studied. All three major biomolecules show a general decline, the significance of which is discussed. &nbsp

CONTAMINATION OF HEAVY METALS IN TANNERY EFFLUENT AND SOIL

This paper analyzes the determination of heavy metals like Chromium, Còpper, Lead and Cadmium deposited in soil as well as in the effluent in the tanneries at Dindigul. The tanneries discharge untreated tannery effluents which get mixed with the soil, water of rivers and canals in this area. The physico-chemical parameters were analysed and heavy metal analysis was conducted by using Atomic absorption spectrometer (AAS). The results showed that all metals such as Cr, Pb and Cd exceeded the standard limits in effluents and soil. Copper concentration was found lower than the permissible limit. All the physico-chemical parameters were present in significant quantities

Contribution to the knowledge of Teloganodidae (Ephemeroptera, Ephemerelloidea) of India

Two new species of Dudgeodes Sartori, 2008 and a new species of Teloganodes Eaton, 1882 are described from India; they are Dudgeodes selvakumari Martynov & Palatov, sp. nov. from Himalayan region (Uttarakhand), Dudgeodes molinerii Sivaruban, Martynov, Srinivasan, Barathy & Isack, sp. nov., and Teloganodes barathyae Sivaruban, Martynov, Srinivasan & Isack, sp. nov. from the Tamil Nadu part of the Western Ghats. Thus, for now, the Teloganodidae fauna of India includes 11 species. Dudgeodes selvakumari sp. nov. appears to be significantly extend northward the known distribution of Dudgeodes. Partial COI sequences were used as an initial clustering method to show the relationships of D. selvakumari sp. nov. with other sequenced operational taxonomic units (OTU) of the genus

Life cycle studies of Heptageniidae (Insecta: Ephemeroptera) in Kumbbakarai Stream of Western Ghats,Tamil Nadu, India

Life cycle studies of Epeorus sp., Afronurus kumbbakkaraiensis and Thalerosphyrus flowersi of the family Heptageniidae were conducted in the Kumbbakarai stream of Western Ghats, southern India. Epeorus sp. may have more than one univoltine brood since part of the eggs hatch in northeast monsoon period and the rest in the following summer. Life cycle of Afronurus kumbbakkaraiensis and Thalerosphyrus flowersi is basically multivoltine with asynchronous, overlapping genera. However, this study reveals the possible influence of summer in numerical reduction of Afronurus kumbbakkaraiensis and Thalerosphyrus flowersi
