Analytical solutions have been obtained for both conservative and non-conservative forms of one-dimensional transport and transport-dispersion equations applicable for pollution as a result of a non-conservative pollutant-disposal in an open channel with linear spatially varying transport velocity and nonlinear spatially varying dispersion coefficient on account of a steady unpolluted lateral i...

This study proposes a framework for estimating pollutant flux in an estuary. An efficient method is applied to estimate the flux of pollutants in an estuary. A gauging station network in the Danshui River estuary is established to measure the data of water quality and discharge based on the efficient method. A boat mounted with an acoustic Doppler profiler (ADP) traverses the river along a pres...

BACKGROUND Toxic substances released into the environment (to both air and water) by many types of industries might be related with the occurrence of some malignant tumours and other diseases. The publication of the EPER (European Pollutant Emission Register) Spanish data allows to investigate the presence of geographical mortality patterns related to industrial pollution. The aim of this paper...

there is no doubt that the way to gain access to religious rulings and doctrines is the sunna of the prophet and the imams, as only second to the holy qur’ān, which is reported in thousands of traditions in various tradition books. in the meantime, every theologian and ḥadīth researcher has to leave behind two stages for a proper understanding of traditions: in the first stage, he is to conside...

This paper presents a novel Neural Network application in order to estimate Air Pollutant Levels. The application considers both Pollutant concentrations and Meteorological variables. In order to compute the Air Pollutant Level the method considers three important stages. In first stage, A process to validate data information and built a threedimensional Information Feature Vector with Pollutan...

BACKGROUND Environmental pollutants are thought to be one of major triggers of atopic dermatitis (AD). OBJECTIVE We attempted to evaluate the clinical effects of environment with low indoor pollutant levels on AD management. METHODS Fifty-one children (mean age 1.7 years) with moderate to severe AD who failed to show improvement with conventional management were recruited. Disease severity ...

Air Pollution plagues urbanised areas and enhances mankind’s vulnerability to the COVID-19 virus. According W.H.O, Kolkata (India) ranks 25th amongst 1100 cities in world. Curbs on traffic movement reduced this pollution during lockdown. Resumption of activities nullified this. This study analyses trend air pollutants, their interrelationships with PM2.5, PM10, resultant National Quality Indice...

The purpose of this paper is to analyse and compare the values of a marginal change in the area of land as a pollutant sink under different decision-making contexts and objectives: international coordination versus national policies for pollutant reduction, and maximization of net benefits versus minimization of costs for pollutant reductions. The analytical results show that a coordinated poli...

Unborn children are exposed to environmental pollutants via the placenta, and there is a causal relationship between maternal intake of pollutants and fetal exposure. Placental examination is an effective way for acquiring data for estimating fetal exposure. We analyzed the concentrations of 104 congeners of persistent organic pollutants, seven organotin compounds, five heavy metals, and methyl...
