Health Risks Due to Radon in Drinking Water

Article Abstract:

Measures and standards for radiactive radon are required by the EPA. This is difficult because radon enters drinking water as an insoluble gas then escapes into the indoor atmosphere posing two sources of risk, inhalation and ingestion. Researchers have begun to create basic tools to measure radon----national average ambient radon concentration data, a transfer coefficient for the movement of radon from water to the air, mathematical models for the behavior of radon in the body. There are as of yet no quantitative studies that link radon exposure to cancer growth though it is a certainty. A multimedia approach is being suggested that will alert citizens through state agencies of the dynamics of radon in the household hopefully leading to the reduction of its concentrations. Issues remain such as the tradeoff between less domestic exposure and greater outdoor exposure. The general issue of radon in the drinking water remains. Many methodological, philosophical, policy and research issues must be addressed.

Estimating the long-term trend in the extreme values of tropospheric ozone using a multivariate approach

Article Abstract:

Data from ozone monitoring sites in Houston, Texas is analyzed for the probability, under different meteorological conditions, that ozone levels may exceed standards demanded by the United States Environmental Protection Agency. A multivariate nonparametric probit regression model is used to analyze ozone data in conjunction with weather characteristics, and the results are graphed for each monitoring site.
