Abstract
Now a day's pollution increases day by day due to industrialization, population explosion, deforestation, and vehicular exhaust & by using fossils fuels which contains nitrogen, Sulphur, carbon. Out of these three N 2, S does not under goes complete combustion which evolved in to atmosphere so the concentration of oxides of nitrogen, oxide of sulphur increases in atmosphere which cause pollution. Due to pollution climate changes, Global warming and Depletion of ozone takes place. Due to global warming if the temperature of earth increases by one degree then water level in the sea will increase by fifty centimeters which causes adverse effects on human beings. The countries like Netherland, Bangladesh, Maldives, shanghai in china, Mumbai and Goa in India will submerge under the sea water. Due to global warming the rate of evaporation of water from the seas, rivers, ponds will increases and this leads to untimely rains cyclones and hurricanes. Agriculture sector will be badly affected. Due to fast evaporation of surface water there will be a shortage of water for agriculture purposes. A slight increase in the global temperature adversely affects the world food production. Due to acid rain toxic effect to fresh aquatic life, damage to plants leaves, change in rate of photosynthesis in the plants and it also extensive damage to historical structural building, the PH of the soil changes which affect its fertility therefore it is necessary to control pollution and to control the pollution it is necessary to know whether observation zone is polluted or not. In the present work Author proved weather observed zone is polluted or not by simple analysis of rain water by using PH-meter and conductivity meter TDS-Meter by the measurement of PH, Conductivity, TDS of rain water we can predict weather studied zone is polluted or not.

  • ... Sulfur, nitrogen , and carbon do not undergo complete combustion, but evolve in the atmosphere by reacting with atmospheric oxygen to form oxides of nitrogen, sulfur, and carbon (NO x , SO x , CO x ). This results in an increase in the concentration of these gases in the atmosphere [15,16]. Consequently, the acid rain conditions developed in a polluted atmosphere lead to the deterioration of metals and alloys subjected to such environments. ...

    The corrosion behavior of aluminum 6060 and 6082 alloys was examined by scanning electron microscopy (SEM), atomic force microscopy (AFM) and dynamic electrochemical impedance spectroscopy (DEIS) after exposure to simulated acid rain for 1, 5, 24 and 48 h. The electrochemical parameters obtained from DEIS were compared with the AFM and SEM studies. Results showed that DEIS is a sensitive technique detecting even very moderate changes in charge-transfer resistance (Rct); it exhibits a very good correlation with surface morphological changes in relation to exposure time. This research also demonstrated the importance of performing corrosion measurements after a longer time period.

    Developments in science and technology have brought improved standard of living, but have also unwittingly introduced some pollution into our environment. The growing trend of industrialization has marked impact on the atmospheric chemistry around the globe. Such impacts are also predicted for developing countries like India. In most industrialized urban areas, the atmosphere has been polluted to such a degree that rainwater is considered unsafe to drink. Rainwater quality analysis is done to mitigate the problems of water pollution and water scarcity through the system of rainwater harvesting. Rainwater may provide the best source of domestic water in areas affected by salinity, high fluoride or pollution from various sources. This is a matter of concern as it is estimated that by 2025, about two thirds of the world’s population - about 5.5 billion people – will live in areas facing moderate to high water stress. So in order to cope with the water scarcity rainwater quality analysis is needed in order to use rainwater as an alternative water supply for human consumption. Rainwater is an important source of fresh water especially for those who live in rural areas, where water use is limited due to scarcity or where surface and underground water quality is poor. Rainwater quality analysis is, therefore, carried out to understand the problems of rainwater contamination with various pollutants. A good knowledge of the chemical qualities of rainwater through regular physico-chemical analysis is necessary so that rainwater can be used as an alternative source of water in future. Hence this study intends to examine the quality of rainwater from selected industrialized areas of Eastern and Northeastern India. 2 | P a g e In the present study, physico-chemical and heavy metal analysis of both direct collection and roof collection rainwater was carried out from selected areas of Eastern and Northeastern India comprising urban, semi-urban and industrial areas. Samples of rainwater were collected from seven different locations which include Irongmara, Badarpur, Bongaigaon, Dolaigaon, BGR Township, Kolkata and Kharagpur. These locations are industrialized and partially industrialized. The sampling sites were selected in such a way as to cover areas representing the semi-urban at the outskirts of the town, highly populated in the old congested city and industrial zones.

    The accelerated corrosion performance of AISI type 316L stainless steel in solutions simulating concrete exposed to acid rain with the use of fly ash as corrosion inhibitor was studied by means of cyclic polarization. Fly ash was added to concrete simulating solutions at proportions of 0–25 wt%. Although 316L showed susceptibility to localized corrosion, the positive effect of fly ash on the cyclic potentiodynamic polarization behavior of 316L is clearly manifested. Fly ash content of 20 wt% in the electrolyte led to the highest corrosion resistance.

    The river Gomati is popularly known as "Aadi-Ganga". Gomati River is an important tributary of river Ganga and perennial river of Awadh plains. The river Gomati originates from Gomat Taal near Madhoganj Tanda village in Pilibhit district (U.P.), run across the major part of U.P. covering nine districts of Shahjahanpur, Lakhimpurkheri, Hardoi, Sitapur, Lucknow, Barabanki, Sultanpur, Jaunpur and ultimately merges in Ganga river, near Saidpur Kaithi in Varanasi. The world is facing problems with a wide variety of pollutants both inorganic and organic in nature. Healthy soil, clean water and air are the soul of life. Often soil, water and air are no longer clean and pure, but pose human health risks. The river Gomati receives huge quantities of untreated sewage agricultural runoff, brings a lot of pesticides, fertilizer, street washouts bringing oil, asphalt, sediment and many types of heavy metals. From industrial effluents to domestic discharge, the river becomes more of a flowing dumping yard. The physico-chemical parameters in water of river Gomati were assessed to know about the water quality in its catchment area. Total of four sampling sites were selected between Gokul ghat upstream and Ramghat downstream. Physico-chemical parameters like pH, Temperature, Total dissolved solid (TDS), Total suspended solid (TSS), Hardness, Dissolved oxygen (DO), Nitrate, Nitrite, Chloride, Total Coliforms and some heavy metals were determined. Changes in water quality of river Gomati due to variations in quantity of parameters were found. Heavy metals mainly Copper, Iron, Zinc, Lead, Arsenic, Cadmium and Nickel were noticed.

    Pollution increases day-by-day due to the population explosion, vehicular exhaust, industrialization, burning of fossil fuels which contain gases like nitrogen, sulphur, carbon and many other, leads to the formation of acidity in the atmosphere, resulting in the form of acid rains. Acid rain is a serious environmental predicament that affects human, aquatic, vegetation, animal life and historical constructions of the world. The present research, presents a methodology for estimating the happening of acid rains using satellite imagery of water vapor and Nitrogen Dioxide (NO2). Initially, the proposed methodology applies k-means clustering method followed by Haar wavelet transform in order to compute normality for water vapor and NO2 satellite imagery. Based on the value of normality, pH value is estimated and if the value lies in the range of 1 ≤ pH ≤ 5, it is detected as acid rain. The proposed methodology in the detection of acid rains is addressed for the first time using clustering and wavelet transformation techniques. The resulted outcome indicates that the amount of rainfall with the concentration of NO2 have a strong influence on the occurrence of acid rains.

    The present study deals with hydrochemical trend of ground water and pollution in Rajapalayam. Water samples were collected from five different region of Rajapalayam town and analyzed for various physicochemical parameters, such as pH, electrical conductivity (EC), total dissolved solids (TDS), total alkalinity (TA), total hardness (TH), Cl-, SO42-, Ca2+, Mg2+, Na+, K+, dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD) were examined through water analysis. The results were compared with standard values as prescribed by the Bureau of Indian Standard (BIS) and World Health Organization (WHO).The results indicate that the ground water samples in the residential area and as well as nearby industrial areas all have high water quality parameters. The persistence of dissolved oxygen (DO) deficit and very high BOD and COD values suggest the deoxygenation rate of ground water which is much higher than reoxygenation and attributed to the mixing of organic wastes, decomposition of plants and animals excretory to overall water quality. Heavy metal content values were present within the permissible limit as prescribed by BIS and WHO. The study samples have TDS values much higher than the maximum permissible level as stipulated by BIS and WHO. The high values of these parameters may have health implication and, therefore, these need attention.

    Acid rain is a major provincial ecological problem around the globe. To control acid rain pollution and to protect the ecological environment, it is a major need to identify the happening of acid rains. This paper presents a methodology for identifying the occurrence of acid rains using satellite imagery of precipitation and SO2. The present analysis applies k-means clustering followed by Haar wavelet transform on the satellite imagery in order to compute normality for precipitation and SO2. By using normality, pH value is computed and if the value lies in the range of 1 ≤ pH ≤ 5, it is identified as acid rain. The proposed methodology is addressed for the first time using data mining and image processing. The resulted outcome indicates that the amount of rainfall with the concentration of SO2 have a strong influence on the occurrence of acid rains.

    Organosulphur compounds were determined in seawater samples by gas chromatography using a pulse flame detection method. The analytical method involved the use of octyl-diol mesoporous silica as a replacement for organic solvents in the extraction and pre-concentration of organosulphur compounds from seawater samples based on the solid phase dispersion extraction technique. The detection limits were in the range 0.6–2 ng S/L, while the repeatability and reproducibility were 7–12% and 13–16% respectively. Relative standard deviations (%) for recovery of n-ethanthiol (n-EtSH), di-n-ethyl sulphide (n-Et2S) and di-n-ethyl disulphide (n-Et2S2) in spiked water samples were in the range 2.2–6.6% (at 0.5 μg/L level). Under the experimental conditions used, quantitative extraction of n-EtSH, n-Et2S and n-Et2S2 was achieved with recoveries ranging from 93% to 99%. The procedure has been successfully applied to organosulphur determination in seawater samples collected from Jeddah beach (West of Saudi Arabia).

    We have repeated a survey of soil pH and native herbaceous vegetation conducted in 1922 by E. T. Wherry, at a site on Long Island, New York. There has been a dramatic decline in surface soil pH. Ridgetops currently have an average pH of 3.8, slopes 3.9, and bottomlands 4.1; bottomlands are today more acidic than ridgetops were in 1922. There has also been a simplification of dominant flora and a dramatic shift to dominance in all habitats of the site by acid-tolerant taxa such as Maianthemum canadense, Viburnum acerifolium, and Aster divaricatus, and a loss of such taxa as Geranium maculatum, Sanguinaria canadensis, and Medeola virginiana. The influence of acidic precipitation on these changes cannot be demonstrated, but remains the most plausible explanation.

    Water is a natural resource. Water quality information is used to protect human health, to preserve and restore healthy ecological conditions, and to sustain a viable economy. The strategy is intended to achieve a better return on public and private investments in monitoring, environmental protection and natural resources management. Geographic information system (GIS) is a very effective technology for environmental management. It is possible to produce solutions in the management studies with many alternatives by using its analytic ability. The objective of this study was to monitor and evaluate spatial and temporal changes in various water quality parameters of Troia water resources, Çanakkale-Turkey. By this aim pH, Dissolved Oxygen (DO), Conductivity, Total Dissolved Solids (TDS), Oxidation and Reduction Potential (ORP) data and Arcview 3.2 software's were used. A total of 25 water samples including springs, river, drainage canal and well water, were collected at eight different times from December 2002 to September 2003 and were tested for pH, DO, EC, TDS and ORP. Global positioning system (GPS) was used to determine the coordinates of sampling points. Employing Arcview 3.2 software and Spatial Analyst, the maps of some water quality indicators were developed to determine the spatial and temporal changes. Results show that surface water conductivity was increased from January to May and it was attributed to the Aegean Sea spray. pH, DO, EC, TDS and ORP value varied from 6.44 to 8.88, 1.77 mg l-1 to 12.08 mg l-1, 0.35 dS m-1 to 6.9 dS m-1, 0.23 mg l-1 to 4.5 mg l-1 and 4.1 mV to 139.7 mV, respectively. DO and ORP values were high in the surface water whereas they were low in the well waters. These changes were attributed to land use types, crop growing periods and domestic sewage in the area.

    Effects of simulated acidic precipitation on food utilization, growth, development, and herbivory of black cutworms (Agrotis ipsilon) on corn (Zea mays L.) in the most economically important life-history combinations of plant and insect were investigated in a series of laboratory and greenhouse experiments. A nutritional-index technique was used in petri-dish experiments with fourth, fifth, and sixth instar black cutworms to determined if acid precipitation could affect the amount of food consumed via affects on insect physiological parameters. Larvae were fed corn plants that were watered two times weekly with simulated precipitation (pH 2.8, 4.2, and 5.6) until the larvae pupated (total deposition of 8-10 cm of precipitation). The inverse relationship between the index of approximate digestibility (AD), which was higher in the pH 2.8 and 5.6 treatments, and the efficiency of conversion of digested food indices (ECD), which was lowest in the pH 2.8 treatment, suggested a stress effect of high acidity. A series of six greenhouse pot experiments was conducted to assess effects of acid precipitation on black cutworms and their interactions with growing corn plants. Fourth, fifth and sixth instar larvae were placed in pots containing soil and corn plants, which were initially in the first or second leaf stage, and simulated acid precipitation (pH 2.8, 4.2, and 5.6) was applied two times per week until the larvae pupated (8-16 cm total deposition). Significant treatment effects were observed in the sixth instar larvae on two-leaf corn experiment, where the larvae grew larger and developed faster in the pH 2.8 and 4.2 treatment. Acid precipitation treatments did not significantly affect black cutworm damage to corn plants in any of these experiments.

    Laboratory simulation of acid stress to a common cladoceran, Daphnia pulex, was conducted in pond water of varying acidity due to addition of H2SO4. An acute test using exposure times of 1 to 96 h and pH levels of 3.7 and 6.5 revealed virtually no effect at 4.3 and higher, while 4.2 and lower severely reduced survivorship. Very short (3-h) exposures caused nearly complete mortality at pH 3.7, while > 12 h exposure caused high mortality at pH of 4.0–4.2. A chronic 21-d life table test indicated a gradually increasing impairment of population growth rate potential (r) at pH 5.0 and below. This was due primarily to reduced survivorship and delayed onset of reproductive maturity. Those individuals which survived at lower pH levels produced broods equivalent to unstressed daphnids. While the tolerance of D. pulex to low pH does not appear to have been reported from field surveys, our results are in close agreement with the observed effects of increasing acidity on the distribution of other zooplankton species.

    Development, reproduction and acaricide susceptibility of Tetranychus cinnabarinus (Boisduvals) (Acari: Tetranychidae) were investigated after long-term (about 40 generations) exposure to various levels of acid rain; pH 2.5, 3.0, 4.0, and 5.6. Deionized water (pH 6.8) served as a control. The mites were reared on eggplant leaves at 28 degrees C, 80%RH and a photoperiod of 14:10 (L:D) in the laboratory. The results showed that the duration of the immature stage was significantly affected by acid rain exposure. The shortest duration (8.90 days) was recorded for populations exposed to pH 5.6 acid rain, while the longest duration (9.37 days) occurred after exposure to pH 2.5 acid rain. Compared with the control population, adult longevity was shortened with an increase in acidity. Similarly, the oviposition duration was also shortened by an increase in acidity. Statistically, female fecundity did not differ significantly between pH 5.6, pH 4.0 and control populations, but did differ significantly between the control population and those exposed to pH 2.5 and pH 3.0 acid rain. This suggested that the mite suffered reproductive defects after long-term exposure to acid rain with higher acidity (pH 2.5 and 3.0). The intrinsic rate of increase among different populations was not significantly affected, but the net reproductive rate of populations exposed to pH 2.5 and 3.0 acid rain was significantly less than pH 4.0, 5.6, and control populations. Bioassay results showed that after long-term exposure to acid rain, susceptibility of the mites to two acaricides, dichlorvos and fenpropathrin, did not change significantly.
