Real-time Monitoring and early detection system which measures the quality standard of waste in Musi River, Palembang, Indonesia is a system for determining air and water pollution level. This system was designed in order to create an integrated monitoring system and provide real time information that can be read. It is designed to measure acidity and water turbidity polluted by industrial wast...
In this article, the Environmental pollution in Iraq was studied by using the remote sensing techniques for the period (2010-2014). In general, the environmental pollution can be divided into three major parts: Air, Water, and soil pollutions. To overcome the problem, multi-satellite images with different resolution and bands at different dates were used to detect and quantize the source of pol...
A recent survey has suggested that up to 25 OOO km of UK sewerage networks may be affected by inpipe sediment deposits. Field evidence indicates that, typically, up to 90% of the pollution load discharged from storm sewage overflows may be derived from the erosion of accumulated in-system sediment, commonly referred to as silt. A sewer flow quality simulation model is being developed under the ...
To design and implement policy to manage water quality, it is important to investigate land use and possible sources of pollution. In this study, using Pearson regression analysis, redundancy analysis and multiple regression analysis, we assess the influence of land use and point sources on water quality in the river system in Shunde district in 2000 and 2010. The results show that water qualit...
—The diatom flora of selected sites in the Animas River Watershed, San Juan County, Colorado, was studied. Eighty diatom taxa were identified from 10 sites: 8 sites on the Animas River and 1 site each on the Cement and Cascade tributaries. The sample diatom abundance was dominated by Achnanthidium minutissimum, Encyonema silesiacum, Aulacoseira distans, Hannaea arcus, and Diatoma mesodon. The p...
To provide the reasonable basis for scientific management of water resources and certain directive significance for sustaining health of Gufu River and even maintaining the stability of water ecosystem of the ThreeGorge Reservoir of Yangtze River, central China, multiple statistical methods including Cluster Analysis (CA), Discriminant Analysis (DA) and Principal Component Analysis (PCA) were p...
The present study deals with the assessment of Langat River water quality with some chemometrics approaches such as cluster and discriminant analysis coupled with an artificial neural network (ANN). The data used in this study were collected from seven monitoring stations under the river water quality monitoring program by the Department of Environment (DOE) from 1995 to 2002. Twenty three phys...
Since ancient times, Japan has been blessed with pure, fresh water. For this reason, Japanese people believe that city water is clean and safe and do not hesitate to drink it without boiling. Drinking fresh, unboiled water has been a part of the Japanese way of life. However, in recent years, pollution of river water and groundwater has increased in this country, making that water neither clean...
An attempt has been made in this present work, to study the seasonal variations of water quality of River Godavari for the period of 2004-2012 at Rajahmundry and Dhawaleswaram located on the banks of River Godavari in Andhra Pradesh. This water quality modelling is done with the help of Water Quality Indices (WQI) computed using NSFWQI and WAIWQI methods. Multivariate statistical techniques nam...
The Itai-Itai disease case is one of four major pollution-related lawsuits occurring in Japan after World War H. This paper, which is based on investigations of the pollution source, the Kamioka mine, considers (1) the history of the disturbances to the environment caused by the Kamioka mine; (2) the Itai-Itai disease suit; (3) the pollution nprevention measures and methods of the Kamioka mine ...
