    Based on the in situ investigation at 3 industrial corporations,we studied calculating total amounts of pollutants in waste water discharges from industries by the method of manual monitoring,which was compared with the methods of automatic monitoring and pollutant discharge coefficients.The potential factors and their applications of these methods are discussed,which offers a feasible way to accurately calculate the waster water pollutant discharges from the industries.

    Pollutants are formed when oil, gas, chemical plants, etc. discharge their harmful waste materials into stream or other water bodies. In this paper, a mathematical model for water pollutants which are soluble and insoluble has been formulated as a system of non-linear ordinary differential equations. Control is applied on insoluble water pollutants to process them into soluble water pollutants. Numerical simulation has been carried out which suggest that soluble water pollutants are increasing as compared to insoluble water pollutants.

    Abstract The characterization and estimation of the manifold properties of environmental chemicals become more and more important for the protection of environment, and so of waters, too. For that reason, since 1975 the “Catalogue of Harmful Water Pollutants” has been edited by the Institute of Water Management, Berlin, GDR. Hitherto four deliveries came out, which comprise the parameters of a total of 700 substances and commercial products. The properties of the harmful water pollutants are described and assessed by 13 different criteria and measures. After the compilation of the results each pollutant is assigned to one of the following three categories: I: Very dangerous water pollutant II: Dangerous water pollutant II: Less dangerous water pollutant. By selected examples from the work of Public Water Control (Staatliche Gewässeraufsicht) the importance of the Catalogue of harmful water pollutants for the practice of the protection of waters and drinking water will be demonstrated. At present the Catalogue is used by nearly 1,200 firms, managements and institutions in the GDR as well as in 39 other states of the world. The second edition will contain an extension of the spectrum of criteria and measures as well as the result of a general revision of all the parameters.

    This review provides an up-to-date overview on silver nanoparticles-based materials suitable as optical sensors for water pollutants. The topic is really hot considering the implications for human health and environment due to water pollutants. In fact, the pollutants present in the water disturb the spontaneity of life-related mechanisms, such as the synthesis of cellular constituents and the transport of nutrients into cells, and this causes long / short-term diseases. For this reason, research continuously tends to develop always innovative, selective and efficient processes / technologies to remove pollutants from water. In this paper we will report on the silver nanoparticles synthesis, paying attention to the stabilizers and mostly used ligands, to the characterizations, to the properties and applications as colorimetric sensors for water pollutants. As water pollutants our attention will be focused on several heavy metals ions, such as Hg(II), Ni(II),Cu(II), Fe(III), Mn(II), Cr(III/V) Co(II) Cd(II), Pb(II), due to their dangerous effects on human health. In addition, several systems based on silver nanoparticles employed as pesticides colorimetric sensors in water will be also discussed. All of this with the aim to provide to readers a guide about recent advanced silver nanomaterials, used as colorimetric sensors in water.

    The removal of toxic pollutants from water is a critical environmental concern due to the potential harm they pose to human health and ecosystems. In this study, we conducted an investigation into the effectiveness of adsorption as a method for removing toxic pollutants from water. Adsorption is a widely used technique that involves the attachment of pollutants to the surface of an adsorbent material, thereby reducing their concentration in the water.
    the experiment mainly inspected the distribution of organic pollutants in the surface waters according to the list of prior pollutants of EPA of USA and also China; It also assessed the surface waters using the multi-pollutants analysis from the aspects of AS1 and AS2.

    The new requirements on the discharge of water pollutants in distilleries according to the new national standards(GB27631-2011) were interpreted thoroughly in this paper.In order to achieve successful discharge of water pollutant in compliance with the new standards,several techniques for water pollutant treatment and pollutant recycling use were introduced.
