In this study, three popular, regionally grown rice varieties (Bario, brown and white) were compared with three of the most popular and highly marketed imported rice varieties (black, glutinous and basmati rice) in Penang region of Malaysia. Rice samples were evaluated for amino acids, fatty acids, minerals, heavy metals and dietary fiber composition. Overall, amino acids content among all the ...

The apparent impacts of overgrowth of population are many. It has direct impact on natural surroundings, i.e. land, water air and natural resources. Lead is found naturally in a variety of minerals. It is most ancient poison known to man. Environmental levels of lead have increased more than 1,000-fold over the past three centuries as a result of human activity. Leafy fresh vegetables grown in ...

Consumers expect organic products to be healthier. However, limited research has been performed to study the effect of organic food on health. The present study aimed to identify biomarkers of health to enable future studies in human subjects. A feeding experiment was performed in two generations of three groups of chickens differing in immune responsiveness, which were fed identically composed...

The nature of trace element carriers contained in sewage and combined sewer overflow (CSO) was investigated by TEM-EDX-Electron diffraction and SEM-EDX. During dry weather, chalcophile elements were found to accumulate in sewer sediments as early diagenetic sulfide phases. The sulfurization of some metal alloys was also evidenced. Other heavy metal carriers detected in sewage include metal allo...

The nutritional composition of the dried seaweed Ulva lactuca from Pameungpeuk waters, including proximate, vitamins, minerals, dietary fibre and heavy metal has been carried out. The objective of this present study is to know the nutritional composition of the dried seaweed U. lactuca for utilisation in human nutrition in the future. Results show that carbohydrate was the major component in th...

Chhatrapur beach placer deposit, situated in a part of the eastern coast of Orissa, is a newly discovered high natural background radiation area (HBRA) in India. The sand samples containing heavy minerals, were collected from Chhatrapur region by the grab sampling method at an interval of ~ 1 Km. Radon exhalation rates were measured by "Sealed Can Technique" using LR-115 type type II in the san...

Introduction: Application of point-of-use (POU) drinking water treatment units is expanding across the world due to the increased concerns about the adverse health effects of water pollution. The main treatment systems of these devices are mostly activated carbon and nano-filter or reverse osmosis. Materials and Methods: This study was conducted to evaluate the effect of using POU units on phy...

abstract mine excavation, concentration and transportation of minerals make southern esfahan municipality and suburb of sepahanshahr vulnerable to pollution and endanger their people by heavy metals. nowadays, spectrophotometers and spectral reflectance of soils in different parts of spectrum are applied for estimating soil characteristics and pollutants. this research was conducted to study th...

introduction: pollution of soil and water environment by release of heavy metals is of great concerns of the last decades. sorption of heavy metals by low cost materials is considered as an inexpensive and efficient method used for removal of heavy metals from soil-water systems. the presence of different ligands with various complexing abilities can change the sorption properties of heavy meta...
