heavy metals in the surface sediments of the two coastal ecosystems of cochin, southwest india were assessed. the study intends to evaluate the degree of anthropogenic influence on heavy metal concentration in the sediments of the mangrove and adjacent estuarine stations using enrichment factor and geoaccumulation index. the inverse relationship of cd and zn with texture in the mangrove sedimen...
metal contents viz., cu, ni, co, zn and cd in sediment cores recovered from the vembanad lake, the largest estuarine-lagoonal system on the west coast of india, were analysed to understand the pollution levels and the impact on the coastal environment. of the three cores studied, vc-10 shown enrichment in all metals compared to other cores, as it is located in the vicinity of industrial area. f...
background & aims of the study: today, the environment pollution with heavy metals has increased. it is important to study various types of pollutions specially those regarding fruits. the effect of pollutions on food safety for human consumption is a global concern. this study was conducted for health assessment of heavy metals pollution (cadmium, lead, and arsenic) in citrus marketed in tehr...
Objective: Metal concentrations in 53 soil samples of Shahr-e-Babak were determined. Methods: Assessment of enrichment factor and geo-accumulation index revealed higher degree of contamination of Cd, Pb, and Cu in soil samples. Moreover, results of metal fractionation study revealed high amount of Cd and Pb are associated in weakly bounds may lead to environmental risk of these metals. Result...
Background and purpose: Osteoporosis and periodontitis are two diseases associated with bone loss and are common among postmenopausal women. There are many contradictory results on the effect of osteoporosis on periodontal tissue. This study aimed to determine the association between osteoporosis and periodontal status in postmenopausal women. Materials and methods: This cross-sectional study...
This research was conducted to evaluate drought tolerance of safflower genotypes (Carthamus tinctorius L.) at the research farm of Isfahan University of Technology, Isfahan, Iran during growing season of 2012. One hundred genotypes including 81 foreign genotypes along with 19 Iranian genotypes were evaluated under normal and moisture stress conditions according to a simple lattice design with t...
INTRODUCTION We examined the best-fit index for describing the constitutional or physical characteristics of Sasang typology for its universal application. METHODS Ponderal index (PI), body mass index (BMI), and basal metabolic rate (BMR) of the nationwide participants (n = 1663; age, 31-60 years) were calculated. We described and analyzed the usefulness of each index for maximizing the diffe...
