Major business groups representing the food industry, including the U.S. Chamber of Commerce, say they will not support long-awaited food safety legislation if it includes an amendment banning bisphenol-A (BPA), a chemical found in thousands of everyday plastics.

The comprehensive bill, which easily passed the U.S House of Representatives with bipartisan support and is expected to come before the Senate in the next month, would give the U.S. Food and Drug Administration more authority over food production and place more responsibility on manufacturers and farmers to reduce contamination in their products.

An amendment by U.S. Sen. Dianne Feinstein, D-Calif., would ban BPA, the primary component of hard and clear polycarbonate plastics — including water bottles, baby bottles, and the linings of canned foods.

“We will not support food safety legislation that bans or phases out BPA from any food and beverage container,” said Scott Faber, vice president for federal affairs for the Grocery Manufacturers Association. (more…)

Many areas of the US have high background radon level in the ground. When radon gets into a home it can increase the resident’s cancer risk. How does radon get into a home?

The most common way is through cracks in basement floors, walls, and sump pump sumps. In the winter, if a furnace or boiler is in the basement, the chimney can act as a depressurization device since combustion air is vented to the outdoors. If the basement is tight, and there is no source of combustion air, the heating system (and water heater too) can depressurize the basement. If there is radon in the soil gas below the house, this depressurization will increase radon infiltration through cracks and sumps.

Another infiltration route is through groundwater. In areas with elevated radon in rock formations, and in homes using on-site wells for water, the water carries radon into the shower where it vaporizes to gaseous radon.
