The major contributor to global warming is considered to be the high levels of greenhouse gas emissions, especially carbon dioxide (CO2), caused by the burning of fossil fuel. Thus, to mitigate CO2 emissions, renewable energy sources such as ethanol

The radiological experience has produced some sophisticated approaches to estimating the environmental risks of anthropogenic chemicals, based on well-validated models for both health effects and exposure assessment. As to exposure assessment, site-

It is shown that contact of skin with contaminated metal can facilitate the transfer of tritium, that the radioactivity absorbed onto the skin enters the body water, and that it follows the metabolic pattern of tritium entering by other modes. Tritiu

In earlier reports from this laboratory radiocalcium movement in the corn root was shown to be highly polarized basipetally, i.e., the direction of transport natural to the intact plant, was preserved in the iso,lated root segment (2). For several re

Root segments of vetch, barley, and pine were exposed to a nutrient solution containing 85Sr and 45Ca tracers. Translocation was measured from solutions containing stable ions at concentrations of 2.5 mm Ca, and at either 0.5 mm or 2.5 mm Sr. Polar t

A rapid extrusion of Na+ from Ulva, induced by light, also occurs with other cations, as evidenced by 86Rb+ and 85Sr2− tracer studies; anion movement (36Cl−, 35SO42− and [14C] acetate) is not affected by light. The Na− flux has a pH optimum o
