Geochemical Modeling of Trace Element Release from Biosolids
Biosolids-borne trace elements may be released to the environment when biosolids are used as fertilizers in farm land. Trace element leachate concentrations from biosolids are known to be limited by both organic and inorganic sorbent surfaces; this experimental evidence has not been previously verified with geochemical modeling of sorption reactions. In this study, pH-dependent leaching experim...
متن کاملTrace Element Analysis in Geochemical Systems by STEM/EDS
Until recently, measurement of trace elements with ppm concentrations has been inaccessible to STEM EDS. Development of fast SDD detectors with solid angles > 1/2 steradian and faster processors are now making such measurements a reality. STEM EDS measurements already have a low brehmsstrahlung background owing to thin samples. However, the combination of high beam currents required to attain s...
متن کاملThe influence of a slow-release multi-trace element ruminal bolus on trace element status, number of ovarian follicles and pregnancy outcomes in synchronized Afshari ewes
Published data on the effects of ruminal bolus on the number of ovulatory follicles in ewes does not exist. The present study determined the effects of a ruminal bolus on trace element status, follicular dynamics and reproductive performance in ewes. Eighty Afshari cycling ewes were synchronized during breeding season using CIDR for 14 days and assigned to 4 groups (n=20); group 1 received a si...

متن کاملSoil Contamination by Trace Metals: Geochemical Behaviour as an Element of Risk Assessment
Trace metals occur naturally in rocks and soils, but increasingly higher quantities of metals are being released into the environment by anthropogenic activities. Metals are chemically very reactive in the environment, which results in their mobility and bioavailability to living organisms. People can be exposed to high levels of toxic metals by breathing air, drinking water, or eating food tha...
