Toxicity Study of Heavy Metals Pollutants in Waste Water Effluent Samples Collected From Taloja Industrial Estate of Mumbai, India,

Abstract The present research work deals with the assessment of pollution due to toxic heavy metals in the industrial waste water effluents collected from Taloja industrial belt of Mumbai. The study reveals that dyes, paints, pharmaceutical and textile industries are some of the major industries contributing to the heavy metal pollutants in the surrounding aquatic environment. It was observed that paint manufacturing industries are the major contributors of toxic Cr, Zn and Pb amounting to 35.2, 33.1, and 31.4 mg/L respectively. It was also observed that major contribution of Cu (33.3 mg/L) was from dyes manufacturing units, while maximum Fe concentration of 12.8 mg/L was found in effluent samples released from textile industries. The concentration of Cd and Ni was found maximum in effluent samples collected from pharmaceutical industries amounting to 35.8 and 33.6 mg/L respectively. The overall results point out high concentration of toxic heavy metals in the effluent samples collected from different industries. These industrial effluents will pollute the near by water bodies affecting the growth of vegetation and aquatic life. These toxic heavy metals when released in aquatic environment will enter the food chain through bio-magnification causing various health problems in humans. The results of the present investigation point out the need to implement common objectives, compatible policies and programmes for improvement in the industrial waste water treatment methods

THERMODYNAMICS OF UNI-UNIVALENT ION EXCHANGE REACTIONS USING STRONGLY ACIDIC CATION EXCHANGE RESIN TULSION T-46

Abstract The study on thermodynamics of ion exchange equilibrium for uni-univalent H + / Na + and H + / K + reaction systems was carried out using strongly acidic cation exchange resin Tulsion T-46. The equilibrium constant K calculated for uni-univalent ion exchange reaction systems were observed to increase with rise in temperature indicating the endothermic ion exchange reactions having the enthalpy values 4.19 and 3.80 kJ /mol respectively

hospital factory for manufacturing customised patient specific 3d anatomo functional models and prostheses

The fabrication of personalised prostheses tailored on each patient is one of the major needs and key issues for the future of several surgical specialties. Moreover, the production of patient-specific anatomo-functional models for preoperative planning is an important requirement in the presence of tailored prostheses, as also the surgical treatment must be optimised for each patient. The presence of a prototyping service inside the hospital would be a benefit for the clinical activity, as its location would allow a closer interaction with clinicians, leading to significant time and cost reductions. However, at present, these services are extremely rare worldwide. Based on these considerations, we investigate enhanced methods and technologies for implementing such a service. Moreover, we analyse the sustainability of the service and, thanks to the development of two prototypes, we show the feasibility of the production inside the hospital
