Abstract Three different studies were carried out in the Department of Weed Science, The University of Agriculture Peshawar, in January 2016 to examine the impacts of polluted water from various sources, water depths and rhizome size on the resprouting ability and establishment of common cattail rhizomes fragments after mechanical control. These experiments were arranged in Completely Randomized Design (CRD), replicated thrice. The selected experimental units were pots 20 inches wide and 12 inches deep. Typha latifolia L. rhizomes were placed in each pots and covered with a little silt to avoid it’s direct contact and desiccation from sunlight. The impacts of water quality on T. latifolia rhizomes sprouting were significant. Lowest ratio of sprouted and un-sprouted buds (50.00 % each), 1st sprout length (37.33 and 40 cm), average sprout length (17.47 and 16.96 cm), average biomass (9.99 and 10.27 g) and growth rate (0.172 and 0.196 g/day) were noted for saline water and industrial acidic effluents, respectively. However, highest rhizome sprouting was recorded for tap water applied as check followed by industrial effluent alkaline. The data regarding the impact of water depth on T. latifolia rhizome sprouting showed that sprouting (44.44 %), 1st sprout length (43.33 cm), average sprout length (20.99 cm), average sprout biomass (7.84 g), average diameter of the newly formed rhizome (0.24 cm) and growth rate (0.4233 g/day) were recorded for rhizomes placed at zero level water depth, while maximum buds sprouted at 4 inches water depth. Similarly, impact of rhizome size on resprouting revealed that minimum bud sprouting (44.44%), 1st sprout length (44.86 cm), average sprout length (0.93 cm) and biomass of newly formed rhizome (4.97 g) and minimum days to emergence (9) were noted for smaller rhizome length (2 buds) compared to longer rhizomes with 10 buds. Therefore, on the basis of our findings, saline and industrial effluent acidic, no standing water (zero water surface level) and shorter rhizome size resulted in least bud sprouting and minimized the chance of further infestation in an eco-friendly and ecological way without the use of herbicides. Whereas alkaline industrial effluents, standing water up to 4 inches and longer rhizome fragments enhanced sprouting and re-establishment of the T. latifolia and these strategies can be utilized where the aim is to grow and establish a good stand of T. latifolia for passive treatment and phytoremediation of industrial effluents, before draining the polluted water into fresh water bodies like rivers and streams.

Three different activated carbons as effective adsorbents were prepared by digesting the stems of Cordia dichotoma, Albizia thompsonii and Polyalthia cerasoides plants in conc. H2SO4 for Cu2+ removal from wastewater. The sorption natures of these sorbents are optimized with respect to various physico-chemical characteristics for the maximum Cu2+ removal using simulated waters. Cordia dichotoma (CDAC), Albizia thompsonii (ATAC) and Polyalthia cerasoides (PCAC) activated carbons show good sorption capacities of values: 97.0, 76.8 and 66.7 mg/g, respectively in a wide pH ranges. Unlike that of other two activated carbons, Cordia dichotoma activated carbon is effective even in acid conditions, indicting its direct applicability to Cu-based industrial effluents which are generally acidic in nature. Interference of two fold excess of co-ions is minimal. The established extraction conditions for the removal of more than 95.0% from 10 ppm Cu2+ solution at room temperature (303 K) using CDAC as sorbent are: pH: 3-9; time of equilibration: 1 h; sorbent dosage: 0.100 g/100 mL; with ATAC: pH: 6-9; time of equilibration: 1.5 h and sorbent dosage: 0.125 g/100 mL; and with PCAC: pH: 6-9; time of equilibration: 2.0 h and sorbent dosage 0.50 g/100 mL. Spent adsorbents can be regenerated and reused until four cycles with minimal loss of adoption capacities. Thermodynamic studies revealed that the sorption is spontaneous and endothermic in nature. Further, the ΔH value for CDAC is 30.156 KJ/mol; it indicates the strong chemisorption and may be through reduction to Cu+/Cu and/or complex formation between Cu2+ and functional groups of the adsorbent. The ΔH values of other two activated carbons, ATAC and PCAC, indicated that the sorption is mainly physical with strong inclination towards chemical nature. Positive ΔS values of all the three sorbents, emphasizes the disorder or randomness at the solid-liquid interface and hence favourable conditions for more penetration of Cu2+ into the surface layers of the adsorbent and hence, more removal of Cu2+ ions. The negative ΔG values indicate that the sorption forces are good enough to cross the potential barrier at the solid-liquid interface and hence the process is spontaneous. The prepared three activated carbons were also successfully applied to industrial effluent and polluted lake samples.

Heavy metals are easily adsorbed to sediments, which can act as a sink and secondary source of these contaminants in water and aquatic biota. The study aimed to assess the potential impact of industrial effluents from Saclux Paint Industry on the recipient sediment quality of Nkoho River in Abia state. Samples were taken at the effluent discharged point, upstream and downstream of the discharge point and geo-referenced using Garmin 76CSx Global Positioning system (GPS). Results of the heavy metal concentration of the receiving water body were compared with that of the effluent. Iron (Fe), Zinc (Zn), Manganese (Mn), Cadmium (Cd), Nickel (Ni), Lead (Pb), Chromium (Cr) and Copper (Cu)) in the sediment and effluent were estimated using Atomic Absorption Spectrophotometer (AAS). The results show that Lead was higher (0.15 – 0.23 mg/kg) in the polluted water sediments than in the control water sediment (0.12 – 0.17 mg/l). In all, Manganese (Mn), Cadmium (Cd), Chromium (Cr), Copper (Cu), and Nickel (Ni) had values which were higher in the corresponding sediments.. The resulting data were subjected to Analysis of Variance (ANOVA) and it shows that there were variations in the quality characteristics of the effluent in the different sampling time (September, October and November) as well as in the quality characteristics of the river water samples at the different sampling points, the paint effluent showed significant variations in its quality over time. In conclusion, it was observed that the poor quality of the water occasioned by the further deterioration by the entrance of the paint industry effluents, confer potentials of health hazards to users of the water.

Introduction: Due to population growth and subsequent limited water resources, the use of treatment plant effluents is of particular importance. Therefore, this study was conducted to identify the environmental effects of the treatment plant and also to identify critical points or weaknesses of the treatment plant system and provide corrective action to reduce the severity of the effects.  Methods: After visiting the research institute and collecting data (during the years 2017-2018), the energy, consuming materials and output of the system were calculated using the life cycle assessment method. Finally, information on the spread of pollution and consumption was included in the list of index effects. To analyze the obtained information, Simapro software (using ILCD 2011 Midpoint V1.03 method) version 8.5.0.0. was applied. Results: Based on the research findings, the software depicted the evaluation of the effects in 13 categories and all the information entered in the software according to the impact, has participated in each category of effects, the most effective factors related to chloride, energy consumption and oil. Conclusion: The results of this study show that the main critical point identified in the treatment plant is related to electricity and the sanitary effluent is in a worse condition than the industrial effluent. However, the environmental impact of industrial effluents should not be neglected. Due to the fact that the MBR method is considered as one of the best methods of wastewater treatment, it is not recommended to change the treatment method, but with continuous monitoring and management of the system, it is possible to reduce the consumption of raw materials.

In view of understanding the impact of effluents and on the occurrence and distribution of macrobenthic organisms, an investigation has been carried out for a period of 8 months from October 2006 to May 2007 in the nearshore water of Thannirbhavi and Chitrapur receiving treated industrial effluents and Bengre coast having estuarine influences. The quality composition of benthic organism revealed the presence of hydroids such as Obeliasp,Cordylophorasp and companularia sp. Polychaetes belonging to 15 diferent families have been identified and their distribution revealed variation with respect to the type of  the effluents.  24 different types of molluscss have been identified and their occurrence and distribution was found to be related to type of sediment and the quality of the effluents. Bulks of crustaceans were formed mainly due to species of Gammarus, Caprellids and Tanaidaceans. The great abundance and diversity of benthic organisms was observed in the Thannirbhavi receiving effluents from a fertilizer industry, when compare to the Chitrapur receiving treated effluents from a dye industry and an oil refinery industry. Silty-clayey sediment harbored higher density of polychaetes where as sandy-silty sediment supported greater abundance of molluscs.

The present study evaluates the impact of industrial effluent on degradation of natural resources and threatening of food security in Gazipur, one of the most thickly industrialized district in Bangladesh. The present survey study was conducted based on pre prepared questionnaire in two locations viz, Sreepur Upzilla and Gazipur Sadar Upzilla during July to October, 2009 with sample size of 50 person. Almost 100% of the respondents identified that untreated industrial effluents degraded surface water and soil along with negative impact on crop, insect pests and animals. The health and proper growth of human, domestic animals and aquatic animals are also affected by awful effects of untreated industrial effluents. The presence of tiny part (4%) of untreated industrial effluent decreases the quality of ground water. To address this alarming sign, immediate action should be taken for saving protecting the ecosystem from unplanned and untreated discharges of industrial effluents here and there.

The biosorption of eight different metals from aqueous solutions of combined industrial effluent by live or dead cells of Phanerochaete chrysosporium was investigated. Growth rate studies of P. chrysosporium were carried out in a selected medium as well as in the effluent. The specific growth rate of the fungus was in the range of 0.089–0.102 h–1 in the medium. The biosorption of metal ions increased as the initial concentration of metal ions increased in the medium. Biosorption equilibrium was established in about 1 h and the concentration of adsorbed metal ions did not change further with time. The equilibrium was well described by Langmuir, Freundlich and Reidlich – Peterson isotherms. The dead fungal biomass was more effective than living fungus for biosorption of metals. The optimum pH for the fungal growth was at 4.5 but enhanced Biosorption was at pH 6 for maximum reduction of hexavalent chromium to trivalent.

Industrial revolutions, advancements in health care, pharmaceuticals, transportation can be attributed to advancements made in the field of science and technology. Environment and natural resources has paid a heavy cost for most of industrial development. Rapid depletion of non-renewable sources of energy eventually leading towards the energy crisis, direct or indirect release of industrial effluents into soil and natural water bodies, global warming are among major consequences of industrialization. Ever since these environmental concerns have been recognized substantial studies have been conducted to minimize, control pollution and restore environment and natural resources. Among several measures cultivation of algae on large scale stands out to be a multipurpose solution. Inherent potential of microalgae species to accumulate lipids makes algae an efficient source of biofuel. Beside this ability of algae to detoxify polluted water and industrial effluent support utilization of algae for environment management and restoration. Efficient CO2 fixation, ability to tolerate wide range of environmental conditions, minimal nutritional requirements further support commercial cultivation of algal species to achieve their widespread application. However, efforts are required to develop large scale cultivation protocols (beyond the range of photobioreactors) so as to achieve practical applicability of algae and their products. Alongwith, cultivation protocols there is simultaneous need of either selection of naturally occurring high yielding strains / species or genetic improvement. Standardization of optimum cultivation conditions along with harvesting procedure is equally important.

The article assesses the impact of various factors on the growth rate of international trade. Many experts interpreted the cross-border flows of goods decline against the backdrop of a growing global economy as an alarming sign that indicates a slowdown in the processes of globalization. To determine the reasons for the dynamics of international trade, the decompositions of its growth rate were carried out and allowed to single out the effect of the dollar exchange rate, the commodities prices and global value chains on the change in the volume of trade. As a result, it was discovered that the most part of the dynamics of international trade is due to fluctuations in the exchange rate of the dollar and prices for basic commodity groups. The negative contribution of trade within global value chains in 2014 was also revealed. During the investigated period (2000—2014), such a picture was observed only in the crisis periods, which may indicate the beginning of structural changes in the world trade.
