Lead (Pb), unlike some other heavy metals, is not essential for higher plants and other organisms. Even at moderate concentrations, lead is highly toxic to man, animals and plants that is why it is considered a dangerous pollutant. In order to quantitatively decipher the effect of the concentrations of lead on the germination and growth of seedling of black gram (Vigna mungo), seed germination parameters were observed using fresh seeds treated with various concentrations of lead nitrate. The study was planned to delve into understanding the possible toxicity effects on seeds upon exposure to lead pollution. Seeds of this plant were exposed to four different concentrations of the metal (e.g. 0.001%, 0.01%, 0.1%, and 1%, w/v). From the results of germination experiments, a decrease in the seed germination parameters with concomitant increase in the heavy metal concentration was observed, and the inhibitions of seedling growth were clearly noticeable above certain acute concentrations (e.g. 1% of lead ion concentration). The results of the study revealed that lead unfavorably influenced the growth parameters as well as biochemical elements of seedling on increasing the metal ion concentration.
The anoxygenic photosynthetic purple non sulphur bacteria are versatile in their habitats and were reported to degrade and remove toxic chemicals in polluted waters. In the present study, 5 photosynthetic purple non sulphur bacteria were isolated from fresh water, Rice fields and Effluents of boiled rice industry from different places of Mahabubnagar and surrounding areas. The isolates were named as KSL-1, KSG-1, BKL-2, KRM-3 and BKG-2 based on the type of the sample, place of isolation and the carbon source utilized. Out of these, KSL-1, KSG-1 and BKL-2 independently, and a mixture of these 3 isolates were used for bioremediation of Agricultural runoff and Domestic sewage. Physical parameters like temperature and pH of the wastes were recorded which varied from 290C - 390C and 6.0 - 8.0 respectively in untreated and treated samples. Chemical parameters like BOD, COD, TDS, TSS, chlorides and sulphates were estimated in untreated samples and samples incubated with the bacteria for 3, 5, 7 and 9 days of incubation. Treatment of Agricultural runoff with these bacteria resulted in overall reduction of BOD 27.4 – 33.5%, COD 13.13 – 46.92%, TDS 16.67 - 50%, TSS 12.5 - 75%, chlorides 16.43 – 46.61% and sulphates 5.47 – 11.64% by 9th day of incubation. Similarly, treatment of Domestic sewage with these bacteria resulted in reduction of BOD 21.1 - 60.2%, COD 16.69 – 63.89%, TDS 33.33 - 48.33%, TSS 47.4 – 80.25%, chlorides 19.34 – 39.62% and sulphates 2.93 – 17.11%. A combination of the three cultures was more effective in reducing the concentration of wastes.
Simple, sensitive and selective methods are developed for the indirect and oxidative spectrophotometric determination of drugs, viz., Phenylephrine Hydrochloride, Ramipril Hydrochloride, Sumatriptan Succinate, Tramadol hydrochloride and Trimetazidine is based on their reactivity towards Chloramine-T (ChL-T).

Corrosion resistance of orthodontic wires of Ni-Cr and Ni-Ti alloys immersed in artificial saliva in the absence and presence of Erythromycin tablets 500 mg has been evaluated by electrochemical studies of polarization and AC impedance Spectra. From polarization study and AC impedance Spectra, it reveals that in presence of Erythromycin tablet in artificial saliva corrosion resistance of Ni-Cr alloy decreases. This is revealed by the decrease in Linear Polarization Resistance (LPR) and the increase in corrosion current (Icorr) value of polarization study and the decrease in charge transfer resistance (Rct) and the increases in double layer capacitance (Cdl) of AC impedance Spectra.These studies reveal that corrosion resistance of Ni-Cr alloy decreases in the order: Artificial Saliva > Artificial Saliva + Erythromycin, Hence, people clipped with orthodontic wire made of Ni-Cr alloy should avoid taking Erythromycin tablet orally. For Ni-Ti alloy, corrosion resistance decreases in the order: Artificial Saliva + Erythromycin > Artificial Saliva. Hence, people clipped with orthodontic wire made of Ni-Ti alloy can take Erythromycin tablet orally without any hesitation. Among these two, Ni-Ti alloy is the best candidate for using orthodontic wire while taking Erythromycin tablet orally.
Chlorpyrifos is an organophosphate pesticide widely used insecticide in agriculture sector to control the varieties of pests and ectoparasites. The present study was under taken to analyze the effect of chlorpyrifos on biochemical constituents of fresh water cat fish H. fossilis. The fish were exposed to sub lethal concentrations of the toxicant chlorpyrifos and the variations were observed in different tissues like gill, liver, intestine, brain and muscle. The biochemical variations were observed in proteins, carbohydrates and ninhydrine positive substances at different time intervals i.e. 24, 48, 72 and 96hrs of exposures. The results revealed that the components of proteins, carbohydrates and ninhydrine positive substances were found to be declined significantly at 72 and 96 hrs compared to 24 hrs and 48 hrs time interval in different tissues of fish H. fossilis on exposure to Chlorpyrifos compared to control. The biochemical levels were found to be declined in all the tissues maybe due to the effect of insecticide Chlorpyrifos.
