Six sigma is a set of tools and strategies for process improvement. Our six sigma study revealed that the automobile manufacturing unit’s major focus was on customer satisfaction and quality of the product. As per six sigma concept, the emphasis was given first on environmental management which is a mandatory requirement. After our study, an ETP was installed by the unit to remove heavy metals, dyes and other chemical impurities from their waste water, so that the treated effluent meets the norms prescribed by the pollution control board. The study indicated that automobile industries may use six sigma tools to make their system environment friendly and comply with legal regulation to protect our environment.

The paper deals with some aspects of waste management, such as the current status of waste collection, transport and disposal in Bhopal, will be illustrated. Also, current situation will be evaluated, and its problems will be identified. Presently, daily amount of Municipal solid waste generated in Bhopal was about 0.45kg per person. Present and
future requirement of container were calculated and discussed based on assumption of population, different solid generation rate (0.3-0.7 kg/ cap/day) and density (300-400 kg/m3). It was found that required container was more when density was assumed as 300 kg/m3, whereas less container was required as assumed density was 400 kg/m3. Some
of physical-chemical characterization of solid waste were calculated and discussed. Average value of density and lower and higher calorific value were found to be 290 kg/m3, 2193 kcal/kg and 2376 kcal/kg respectively. Choice of disposal method should be based on the nature of the waste. Based on the sample characterization of solid waste generated in Bhopal Municipal Area, biodegradable waste generation was 370 metric tons/ day, whereas non biodegradable waste were 430 metric tons/day. The biodegradable part of the waste, if segregated at source, can be treated by composting. Composting of waste yields a soil conditioner, which can be used for farming and gardening purposes. The site should be fenced to restrict unauthorized entry and surrounded by open drains to collect surface run-off from the disposal site. The sanitary landfill site should have proper access roads for the container carriers, to avoid accessibility problems during the monsoon

Viscometric and ultrasonic studies of Glycine has been carried out in Methanol + water and Ethanol + water co-solvents at different temperatures 30, 35 and 40oC respectively. From these experimental data, derived thermodynamic parameters such as the isentropic compressibility (s), intermolecular free length (Lf), acoustic impedance (z), molar compressibility (w), molar sound velocity (R) and apparent molar compressibility (k) have been computed using the standard relations. The results have been analyzed on the basis of variations in thermodynamic parameters. The variations in Ultrasonic velocity and adiabatic compressibility with concentrations in both systems show a similar trend of increasing ultrasonic velocity and decreasing in adiabatic compressibility of the constituent electrolytes at different temperatures. This is due to complex formation and coordinate covalent bond formation between the molecules of the liquid mixtures. The results are discussed in terms of structure – making or structure – breaking effects of amino
acids in the mixture.

A highly sensitive, simpler, economical and faster visible spectrophotometric method has been established for determination of hydroquinone in some common cosmetics in Najran region. The method is based on using ammonium molybdate in acidic medium as an oxidizing agent for conversion of hydroquinone to p-benzoquinone. As a result of higher absorption of visible light by (MoV) producing from reduction of (MoVI). The effect of various parameters such as amount of oxidizing agent, temperature, and solvents has been studied upon the absorption of (MoV). Under optimum conditions, Beer’s law was obeyed in the range of 10-100ug/ml at 580nm using methanol as solvent with linear regression coefficient of 0.9999. The newly developed method has been successfully applied to diluted samples of various skin lightening creams for hydroquinone determination.

Hospital waste is highly infectious and can be a serious threat to human health if not managed scientifically in discriminated manner. Public concern over disposal and treatment of medical waste has resulted in increasing regulation and court actions. The generators include hospitals, clinics medical research facilities. Hospitals, other health care units & research facilities in our country produce million of tons of waste every year. This waste is often mixed with municipal waste, dumped in landfills where it can contribute to environmental pollution. Government & public hospitals should act as the leaders model in demonstrating safe disposal of medical waste.

The Isolation, Extraction and Transportation studies of transition metal cations (Cu2+, Co2+,Ni2+ and Zn2+) with Ionophore 1-phenylazo-2-naphthol or (S-I)were examined. The Isolation studies were performed to study the interaction between Metal ions and Ionophore in Organic solvent. These studies were focused on the capacity of the ionophore to extract metal cation from an aqueous phase into an organic phase by complexation. In the Extraction and Transportation studies chloroform is used as an Organic Phase. On comparing the results of Extraction and Transportation studies it is observed that some cations have been found selective for extraction while others are more selective for transportation with ionophore. This selectivity can be applied for ion selective electrode and other redox devices. It is also helpful for environmental studies. The results of this study will be useful for various applications in Chemistry, Biochemistry, molecular sensors and switches, liquid crystals and for artificial systems

The mixed ligand complexes of Pb (II) and T1 (I) with TDSA in aqueous with some amino acids (Glutamic Acid, Aspargine, Glycine and L-methionine) have been investigated at the dropping mercury electrode (DME) at constant ionic strength KNO3 (m=1.0m) and 303 ± 2K temperature. Triton x-100 (0.002%) was used as maximum suppressor. The reduction of Pb (II) and T1 (I) were found to be reversible and diffusion controlled, involving two electrons [Pb(II)] and one electron [T1(I)] respectively. It was found that only a single mixed ligand entity MAiXj is formed. The stability constants have been evaluated by Souchay and Faucherre’s method.

The kinetics and mechanism of Oxidation of glycollic acid with Bi(V) has been investigated in phosphoric acid medium.The order with respect to substrate and oxidant each is one. The reaction rate is independent of [H+] ion as well as [Bi (III) ]. The reaction rate decreases with increasing ionic strength indicating reactive species of opposite charge. The simple rate law explained all the experimental observations. The mode of electron transfer from the substrate to Bi(V) has been indicated is a bridged outer sphere mechanism.
