As geographical information systems (GIS) are increasingly being applied to surface and subsurface flow and transport modeling issues, it becomes important to more clearly define potential advantages and achievable objectives with this technology. This chapter describes an integrated conceptual framework for predicting basin-scale solute loading rates through and from the vadose zone. The appro...

Blood is a rich source of iron and proteins of high nutritional and functional quality. Because of the high protein content of blood, generally about 18% [1], it is sometimes referred to as “liquid protein” [2]. It has been estimated that the approximately 1,500,000 tons of porcine blood produced yearly in China has a protein content equivalent to that of 2,000,000 tons of meat or 2,500,000 ton...

the recently published articles in the iranian journal ofbiotechnology inspired us to write this short communication on nitrogen dioxide no2-philic plants (1).to cope with environmental pollution, we thought(still think) that development of methods that mitigatepollution is an urgent issue, and that no2-philic plantsthat can grow with no2 as the sole nitrogen source areinstrumental for the impl...

Kriging is an interpolation technique that is used to estimate a variable at an unmeasured location from observed values at nearer locations. In this study, it is used to analyze the spatial distributions of the health risk of indoor air pollution. The study case is an air-conditioned office building that has 16 floors, located in Taipei, Taiwan. The Kriging method is used in drawing health ris...

twenty samples of the recent sediments were collected from the tigris river and some of its tributaries of northern iraq and twelve samples from the miocene and quaternary sediments. the study is conducted to define and assess the paleoenvironmental pollution by some heavy metals in these sediments in order to elucidate the probable source rocks and the main mineral phases suggested to be a sou...

We analyze the transport of pollution across the Pacific during the NASA INTEX-B (Intercontinental Chemical Transport Experiment Part B) campaign in spring 2006 and examine how this year compares to the time period for 2000 through 2006. In addition to aircraft measurements of carbon monoxide (CO) collected during INTEX-B, we include in this study multi-year satellite retrievals of CO from the ...

A primary objective of current air pollution research is the assessment of health effects related to specific sources of air particles or particulate matter (PM). Quantifying source-specific risk is a challenge because most PM health studies do not directly observe the contributions of the pollution sources themselves. Instead, given knowledge of the chemical characteristics of known sources, i...

Thank you Admiral Watkins and commission members for allowing me this opportunity to draw your attention to two recent reports of the National Academies that address what are arguably two of the most significant challenges to coastal and marine environmental quality: oil pollution and nutrient pollution. A decade ago public concerns about marine pollution were driven by the dramatic footage fro...

INTRODUCTION Indoor air pollution from biomass fuel use has been found to be responsible for more than 1.6 million annual deaths and 2.7% of the global burden of disease. This makes it the second biggest environmental contributor to ill health, behind unsafe water and sanitation. METHODS The main objective of this study was to investigate if there was any association between use of bio-fuels ...
