    © 2018 by the author. Licensee MDPI, Basel, Switzerland. This review summarizes the findings from studies of trace element levels in marine sediment and organisms in the Gulf of Thailand. Spatial and temporal variations in trace element... concentrations were observed. Although trace element contamination levels were low, the increased urbanization and agricultural and industrial activities may adversely affect ecosystems and human health. The periodic monitoring of marine environments

    Trace elements in thai breast milk and infant formulas
    (1985-06-01) Pipop Jirapinyo; Prapa Pringsulaka; Sompool Kritalugsana; Wirapong Chatranon; Burana Chavalittamrong; Mahidol University; Department of Pediatrics
    A total of 150 breast milk samples obtained from Thai mothers of preterm and full-term infants, during the 7th to 28th day of lactation, and 60 samples of infant formulas obtained from local markets were analyzed for zinc, copper and chromium concentrations using atomic absorption spectrophotometry. The mean zinc concentration of breast milk and infant formulas were 1.9 mg/l and 2.9 mg/l respectively. The copper concentrations in breast milk and infant formulas were approximately 0.4 mg/l. The chromium concentrations were 0.08 mg/l and 0.07 mg/l from milk of mothers of full-term and preterm infants respectively, while the chromium concentration of infant formulas was only 0.05 mg/l. This study indicates that the zinc and copper content of the infant formulas are not sufficient as daily requirement for the infant's growth. © 1985 Oxford University Press.

    The nutrient value of Thai rice and bean in terms of minor and trace element content has been evaluated using INAA. Six varieties of rice and six of beans bought from three local markets in 2006-2007 were investigated under this study. Elemental... compositions were determined using the comparator technique. Precision, accuracy and detection limits of each element found were also calculated. Three minor (Ca, K, Mg) and eight trace elements (Al, As, Br, Cl, Cu, Fe, Mn, Zn) were determined in these Thai

The most prominent result was that calcium concentration in red cells increased significantly... in thalassemia subjects, particularly in splenectomized cases. These results might reflect the abnormal trace element metabolism and defects in the calcium transport system of the red cell membrane in thalassemia.
