Don't Bite the Dust - main dishes in spain restaurants

Last week, including a report, some cat food, especially fish
A seasoned canned main course that provides a large amount of Bromo flame retardant for a pet's diet.
This finding helps explain why the blood concentration of these ubiquitous chemicals
Called polymethyl bromide (PBDEs )-
Cats are often much higher than people in the United States.
However, this is not to say that people are only exposed slightly.
Some studies have shown that both children and adults can accumulate a large amount of these hormones.
Disrupting Agents
Certain foods, especially fish, chicken liver and certain sausages, can provide a large amount of food.
In addition, recent studies have found that mothers usually pass PBDEs to their children --
Both in the uterus and during lactation.
In general, manufacturers add PBDEs to plastic and foam products to reduce their chances of catching fire.
However, treated products can discharge chemicals into air, water and dust.
By still some rough exposure routes, PBDEs have entered the United StatesS. food supply.
As a significantly larger source of human contact, what is emerging is the intake of PBDE-
Dust of the house.
This gives toddlers the greatest risk of accumulating chemicals because of the time they spend on carpets, Mouse toys and other indoor items --dust magnets.
In fact, the authors of the new cat study raised objections in the report.
The 15 th issue of "home cat" can be used as a sentinel to better assess human exposure and poor health outcomes associated with low weight
But exposure to PBDE for a long time.
"Studies have shown that short early PBDE exposure, at least in young animals, can slightly damage learning and lower the thyroid gland --
Hormone concentration in the blood.
Late-life exposure delays puberty in male rodents, and adult exposure prevents the activity of male sex hormone cell receptors.
And new cat research.
It initially linked PBDE exposure to the development of potentially fatal thyroid disease.
No one knows if these flame retardant will pose a similar risk to people.
If so, what concentration can be harmful.
Just data is not there.
Prior to this, animal data showed that cautious parents may want to smoke regularly and limit their children's intake of certain foods.
Just a year ago, Douglas Fisher, Oakland, California
The forum works with some international scientists.
Then twice, a few months apart, the team came to a family in California.
The goal is to assess possible differences in PBDEs accumulation among family members who have a common lifestyle and environment on the surface.
In the October 2006, the group reported that in its first visit in September, the concentration of PBDEs in the blood of fathers and mothers was 32 and 50/billion (ppb), respectively ).
By contrast, a 5-year-
The eldest daughter has 137 ppb PBDEs in her blood, 18-month-
Part of the weaned elderly toddler son contains PBDEs of 245 ppb.
After three months, the PBDE value for all family members dropped.
However, the early trends are still present: the blood of the father and mother contains about 4 ppb PBDEs-roughly one-
A tenth is as much blood as their toddler, one quarter to the third quarter and their 5-year-old's did.
Scientists can't explain the huge seasonal differences in pollution levels, but they suspect that family members may have encountered a large number of temporary flame retardant sources in September.
The team ruled out the possibility that the difference originated from the measurement error, as it did the validation test at each sampling.
The authors speculate that indoor dust is a major difference in the levels of PBDE pollution in adults and children.
They noted that a 2005 study found evidence that house dust could account for 80% of total daily PBDE exposure for toddlers
Almost six times the exposure of adults.
However, eating also increases the burden on young people on chemicals.
Based on previous studies of PBDE values in breast milk, the authors say they suspect that breastfeeding "significantly improves the level of [some] specific PBDEs observed in toddlers ".
The researchers concluded that children seem to have a higher concentration of PBDE than adults, and the concentration may be high enough to cause harm.
"Just last month, researchers in Spain investigated the PBDE exposure caused by breast milk.
They measured the concentration of PBDEs in the blood of 92 children at birth and another 244 preschool children around 4 years old.
Although the baby's blood at birth contains polyfluoride ether of about 3 ppb, the value of preschool children is much higher
About 13 ppb if they are recipe
Feeding in the form of a baby, close to 70 ppb if breastfeeding.
In fact, scientists reported in the July 15, although these young people had relatively short breastfeeding times --typically 4. 5 months—
"Breastfeeding is a determining factor in the physical burden of these compounds at the age of 4.
"Last year, a team of British scientists reported PBDE concentrations in the air sampled in homes, office buildings, post offices, coffee shops, restaurants and car interiors.
The researchers found that in general, the car "showed the highest average concentration of PBDEs" in the indoor environment ".
However, with the aging of the vehicle, the concentration in the air of the flame retardant tends to decrease, indicating that the flame-
Gradually escape from foam and plastic cars.
The researchers reported in the December, internal components. 15 .
Although there is some middle
Most families, Century homes can carry airborne PBDE values of 100 photos per cubic meter
Especially built in the last 17 years.
Register in very low pg/m range.
The three months of grams are quite small, and no one knows if they have biological activity in humans.
What is another source? Some studies of common foods suggest
Fat dairy products and meat are particularly important sources of PBDEs in the human diet.
Among the foods that stood out from last fall's study of Dallas supermarket goods: the authors pointed out in the October 2006 that PBDE pollution values may vary significantly in the product category.
For example, in meat, the PBDE value of Bacon usually does not exceed 39 ppt, while a pork sausage contains a flame retardant substance of 1,426 ppt.
From a point of view, the researchers pointed out that the PBDE value in sampling breast milk is usually between 1,000 and 21,000 ppt.
The new study of domestic cats and the investigation of PBDE pollution in supermarket food in last October all pose a difficult problem.
The Environmental Protection Agency's toxicologist and co-author of the two studies, Linda Burnbaum, explained that the two sets of data showed that food did not account for the majority of the flame.
Delays found in people or pets in the United States.
In fact, her team had calculated the possible daily PBDE intake in the food and found that it was not impressive.
Total intake can lead to blood
The PBDE value is less than 10 ppb, the researchers noted.
In the United States, however, the average blood value is more than 30 ppb. S.
5% of people have blood.
The value of PBDE is 10 to 100 times that of this value.
Birnbaum told reporters that such figures "show that indoor dust is an important source of [PBDEs ".
Data from a study published in March 1 support this suspicion. Thomas F.
Webster of Boston University and his colleagues have shown a strong positive correlation between breast milk and PBDE concentrations in indoor dust among new mothers in the Boston area.
"In general, breast milk from women with flame-rich dust in their homes --
The flame retardant residue has PBDE concentration 2.
6 times the milk of women with low PBDE concentration in household dust.
Birnbaum and her collaborators said that because domestic cats may occupy the same environmental position as young children at home --
Whether crawling around or having dirt in your mouth
A better understanding of how cats are exposed to flame retardant and the effects of these exposures on hormones "may have a public health impact on veterinarians and human patients.
