Water is one of the most crucial substances for life. In order to maintain their public health, each and every country has defined standards of drinking water quality, beyond which the water is considered harmful for human health. The current study compares physical, chemical, and biological standards of drinking water quality for the USA, EU, Japan, India, and Bangladesh, considering 4 physica...

the quality of surface water within a region is mainly influenced by natural processes such as precipitation, soil erosion and weathering, geology, vegetation and anthropogenic activities. the most important factor is geological formation in watershed and water flow path. in this study, the spatial variations of physical and chemical parameters of surface water including ec, sar, cl and tds and...

Drinkability of water is determined based on its physical, chemical, and microbial properties. Undesirable changes in these parameters could threaten the health of consumers. The present study aimed to assess the physical, chemical, and microbial parameters of the drinking water sources in Sanandaj, Iran and compare them with the national standard values. This descriptive, cross-sectional study...

sulforaphane, an isothiocyanate found in broccoli and other cruciferous vegetables. it is an antioxidantand anti-cancer agent, and reduces blood pressure, and also has anti-allergic effects.in this article, six theoretical methods have been used for calculation of physical parameters insolforaphane and several similar compounds. we calculated physical parameters like atomic charges.energy (ae) ...

The objective of this study was to evaluate the physico-chemical quality of honeys samples of stingless bee (Meliponinae). Physico-chemical analyses were: moisture, color, pH, acidity, electrical conductivity, hydroxymethylfurfural, ashes, diastasic activity, reducing sugars, and sucrose. For the parameters hydroxymethylfurfural, ashes, reducing sugars and sucrose, the samples complied with the...
