The Impact

A laboratory river model for the study of self-purification inhibition in a stream containing toxic substances is presented. It enables an engineering - technological prediction of the impact of toxic substances or wastewaters on dissolved oxygen (DO) profile in an organically polluted river downstream from the point of entry of toxic effluent thus providing rapidly and inexpensively significant design information to an environmental scientist or engineer. The method was applied to the toxicity evaluation of wastewaters from electroplating industry. The effects of copper, cyanide (representing two significant constituents of this type of wastewaters) and wastewater from electroplating industry on the biodegradation of organic municipal pollution in receiving stream were evaluated experimentally.

Sewage sludge and its management constitute one of the most important environmental problems. The introduced the Sewage Sludge Directive 86/278/EEC advocate utilization of sewage sludge in agriculture. However, this method is limited mainly by the availability of heavy metals and pathogens. An ecotoxicological assessment of sewage sludge doses applied to soil, recommended in the Polish Regulation of the Minister of Environment of 6th February 2015 on municipial sewage sludge, was carried out. The sewage sludge was added to soil in the amounts of 3, 6, 9, and 15 Mg/ha. The produced mixtures were subjected to physicochemical and ecotoxicological tests, involving the biomass and mortality tests of Eisenia fetida earthworms. The sewage sludge had a statistically significant impact on the increase in: electrical conductivity, total exchangeable cations, organic matter content, organic carbon, nitrogen and heavy metals of the considered soil. The impact on the biomass of earthworms was different; after 7 days in the mixtures with 3 Mg/ha and 6 Mg/ha sewage sludge addition, the biomass increased approximately by 1.3-fold, in comparison to non-modified soil. At 9 Mg/ha, it reduced by 1.3-fold, whereas at 15 Mg/ha – by 16-fold, in relation to the initial value. The studies indicated that the ecotoxicological assessment of wastes may be employed as environmental safety control measure of the sewage sludge application in agriculture.

The Impact

Gomati River originate from Madhoganj Tanda village in Pilibhit district, U.P. it passes through the district of Shahjahanpur, kheri, Hardoi, Sitapur, Janpur and ultimately merge in Ganga. River water is significant for every living organism as well as aquatic life. Water pollution is a major global problem. Modernization and urbanization have polluted the river water and degraded the status. All over the world we are seeing that drain is the main source of water pollution especially for rivers flowing within the city. This drain generally carries industrial effluent, domestic waste, sewage and medicinal waste resulting in poor water quality. Gomati River receives industrial as well as domestic waste from various drains of Lucknow city. As Gomati river is the only source of surface water near the communities. A total 20 parameters namely Temperature, pH, Turbidity, Conductivity, Total dissolved solids (TDS), Total suspended solids (TSS), Total solids (TS), Dissolved oxygen (DO), Biological oxygen demand (BOD) Chemical oxygen demand (COD), Alkalinity, Total hardness, Calcium as ca, Magnesium as Mg, Chloride, Fluoride, Sulphate as So4, Nickel as Ni, Lead as Pb, and Zinc as Zn where analysed and their variation is discussed to obtain the impact of effluents on water quality. From the result it was found higher than the permissible limit of WHO and BIS.

ABSTRACTResident microbes (microbiota) can shape host organismal function and adaptation in the face of environmental change. Invasion of new habitats exposes hosts to novel selection pressures, but little is known about the impact of invasion on microbiota and the host-microbiome relationship after this transition (e.g., how rapidly symbioses are formed, whether microbes influence invasion success). We used high-throughput 16S rRNA sequencing of New Zealand (native) and European (invasive) populations of the freshwater snail Potamopyrgus antipodarum and found that while invaders do carry over some core microbial taxa from New Zealand, most of their microbial community is distinct. This finding highlights that invasions can result in the formation of novel symbioses. We further show that the native microbiome is composed of fewer core microbes than the microbiome of invasive snails, suggesting that the microbiota is streamlined to essential members. Together, our findings demonstrate that microbiota comparisons across native and invasive populations can reveal the impact of a long coevolutionary history and specialization of microbes in the native host range, as well as new associations occurring after invasion. We lay essential groundwork for understanding how microbial relationships affect invasion success and how microbes may be utilized in the control of invasive hosts.

The impact of detergent effluent on the growth, yield and foliar epidermal characters of tomato (Solanum lycopersicum L.) was investigated. The variety of tomato ((ROMA VF) was grown on soil contaminated with different concentrations (5%, 10%, 15%, 20% and 25%) of the effluent. It was observed that the effluent affected the time of germination, flowering and fruiting of the tomato plant. The number and weight of fruits produced were also affected although the extent varied with concentrations. There were significant variations in the plant height, stem girth, number of leaves, number of fruits and weight of fruits among the different treatments at 0.05 level of probability. At lower effluent concentrations, it was observed that the growth and number of fruits were relatively higher than the control (plants not treated with the effluent). The foliar anatomical study on the tomato showed that the effluent affected the structures of the plants. Significant reductions were observed in the stomata density, trichome frequency and number of epidermal cells on both the adaxial and abaxial surfaces as the concentration increases. This study revealed that detergent effluent had significant effect on the growth, yield and the foliar anatomy of Solanum lycopersicum especially at higher concentration (25%).

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.

The Impact

Aim: This research work aimed to determine the impact of industrial effluent discharge on the physicochemical properties of Aleto Stream, Eleme and Rivers State. Study Design: Random sampling technique was applied in this study. The study area was divided into three sites; upstream, downstream all of Aleto Stream and Agbonchia Stream which serves for the control experiment. Water samples for eleven physical and six chemical parameters were collected in a Completely Randomized Design. Place and Duration of Study: This study was carried out on Aleto and Agbonchia streams at Eleme, Rivers State, Nigeria from 2017 to 2018. Methodology: Two samples were collected; one sample at the Aleto stream where the industrial effluent is being channelled into the stream and the other sample was collected from Agbonchia stream, which was used as a control. In the Aleto Stream, sampling was made at two points; point A (upstream) point B (downstream) and each of these points had their Physico-chemical properties tested while only one sample was collected from the Agbonchia Stream. Physico-chemical properties were analyzed in the samples using pH meter for pH, Turbidity meter for turbidity, Conductivity meter for electrical conductivity, phosphate by colourimetric method, total dissolved solids (TDS) and total suspended solids (TSS) by gravimetric method, biochemical oxygen demand (BOD) and chemical oxygen demand (COD) by standard method, chloride, alkalinity, dissolved oxygen (DO), calcium hardness, total hardness by titrimetric method, colour, odour and taste by sensory method. Results: Results obtained on the Physico-chemical properties had varying concentrations of Temperature, Total hardness, Chloride, Alkalinity, DO and Phosphate that were within world health organization (24)  and Federal Ministry of Environment (1991) permissible limits on both upstream and downstream with values ranging from 29.0-23.7oC, 360-125 mg/l, 120-100 mg/l, 36-30 mg/l, 4.9-4.4 mg/l, 1.92-1.2 mg/l respectively while Electrical conductivity, Turbidity, TSS, TDS, Calcium hardness, COD, BOD, Colour, Taste and Odour were above permissible limits on both upstream and downstream with values ranging from 1660-1700 mg/l, 83-112NTU, 82-80 mg/l, 910-914 mg/l, 1590-1900 mg/l, 100-165 mg/l, 4.36-3.88 mg/l respectively. The pH values ranged from 9.0-6.3 mg/l showing a result on the upstream to be alkaline while the downstream was slightly acidic. The increase in the above parameters above their permissible limits is as a result of the impact of industrial effluent discharges drained into the stream. This indicates that the stream is unfit for both human and aquatic inmates. Conclusion: Therefore, proper management of this effluent should be ensured and an acute test with lethal concentration (LC50) as the endpoint is recommended to determine the degree of toxicity of the effluent waste.
