Researchers analyzed all 30.1 million births in the United States between 1996 and 2002. They found a strong association between higher rates of birth defects among women whose last menstrual period was in April, May, June or July and elevated levels of nitrates, atrazine and other pesticides in surface water during those same months.

Microwaved water and other liquids do not always bubble when they reach the boiling point. They can actually get superheated and not bubble at all. The superheated liquid will bubble up out of the cup when it is moved or when something like a spoon or tea bag is put into it. To prevent this from happening and causing injury, do not heat any liquid for more than two minutes per cup. After heating, let the cup stand in the microwave for thirty seconds, before moving it or adding anything into it.
It is caused by a phenomenon known as super heating. It can occur anytime water is heated and will particularly occur if the vessel that the water is heated in is new, or when heating a small amount of water (less than half a cup). What happens is that the water heats faster than the vapor bubbles can form. If the cup is very new then it is unlikely to have small surface scratches inside it that provide a place for the bubbles to form. As the bubbles cannot form and release some of the heat has built up, the liquid does not boil, and the liquid continues to heat up well past its boiling point. What then usually happens is that the liquid
is bumped or jarred, which is just enough of a shock to cause the bubbles to rapidly form and expel the hot liquid. The rapid formation of bubbles is also why a carbonated beverage spews when opened after having been shaken.

Plastics have become such a pervasive part of our daily lives that it can be difficult to do without them, even when we are concerned about their safety. But most of the plastic bottles and containers we use carry a recycling symbol that can be a help in deciding how to use them.
You’ve been hearing all kinds of bad news reports about toxic chemicals leaching from plastic bottles and containers. If you heat these bottles or re-use them, you might be increasing your exposure to hormone mimics or any of a number of other chemicals. But plastic is all around us, and not all of it is hazardous to your family’s health. How do you know which types of plastics are worse, and which are not as bad? One clue is the number inside the recycling symbol on the bottom of the bottles or containers. The numbers indicate which are accepted by recyclers, but they also indicate the class of plastic and its chemical characteristics:
No. 1 PETE or PET (polyethylene terephthalate) water-disaster.pps
No. 2 HDPE (high density polyethylene) CLICK ABOVE
No. 3. V (vinyl) or PVC to watch 20 slide
No. 4. LDPE (low density polyethylene) presentation
No. 5. PP (polypropylene)
No. 6. PS (polystyrene)
No. 7. Other or miscellaneous
To sum up, if the bottle has the number 1, 2, 4, or 5 on the bottom, it’s made from one of the safer plastics.
If the number says 3, 6, or 7, there is a greater likelihood that the bottle will be leaving a chemical residue in your beverage. Category No. 3, PVC or polyvinyl chloride, is the worst, followed by No. 7, which may contain polycarbonates (bisphenol-A).
Another rule of thumb is that the softer the plastic the more likely that leaching can occur. You can also use your nose. If you sniff a hint of plastic, find another container. Of course, your best bet is to avoid plastics for food and beverage altogether, and use glass, metal, or ceramic refillable containers whenever possible.
