Study: Chemicals used in plastics can affect babies in the womb

Chemicals used in plastics feminise the brains of little boys 'so that they avoid rough and tumble games'

Chemicals used in plastics are 'feminising' the brains of baby boys, a disturbing study shows.

Those exposed to high doses in the womb are less likely to play with 'male' toys such as cars. They are also less willing to join 'rough and tumble' games.

The research adds to growing evidence that hormone-disrupting chemicals in thousands of household-products are interfering with the development of children.

Environmental campaigners called the study 'extremely worrying' and called for a crackdown.

The study looked at phthalates, chemicals which can mimic the female sex hormone oestrogen.

Some experts believe they are partly to blame for the increase in genital defects in boys and lower sperm counts in men over recent decades.

But the new research is the first to link hormone-mimicking chemicals to behaviour.

There are fears of further effects as the young children in the study grow up.

Although the plastics industry insists phthalates are safe, the EU has banned many of them from cosmetics, teething rings and children's toys.

But pregnant women are still exposed to phthalates, which are used to soften plastics in household items such as plastic furniture, shoes, PVC flooring and shower curtains.

They can also be transferred to food and drink from plastic packaging. The new study, published in the International Journal of Andrology, was led by Dr Shanna Swan, professor of obstetrics and gynaecology at the University of Rochester in New York State.

Her team tested urine samples from mothers in the 28th week of pregnancy for traces of phthalates.

The women, who gave birth to 74 boys and 71 girls, were contacted again when their children were aged four to seven and asked about the toys the youngsters played with, the activities they liked and their personalities.

The researchers found that higher concentrations of two types of common phthalate - DEHP and DBP - were strongly linked with more feminine play in the boys but had no impact on girls.

The higher-phthalate boys were less likely than other boys to play with cars, trains and guns or engage in rough-and-tumble games such as playfighting.

where chemicals are found

They preferred 'gender-neutral' activities such as sports.

Professor Swan believes the chemicals reduce levels of the male sex hormone testosterone in unborn babies during a critical window of development between the eighth and 24th week of pregnancy.

This alters the development of the brain as well as male genitals.

She said last night: 'If replicated, these findings would be of serious concern because they indicate that these common chemicals can significantly alter the development of the male brain.'

A previous study by Dr Swan found that boys whose mothers had the highest phthalate levels were more likely to have undescended testicles and smaller genitals than other baby boys.

In animal studies, males with similar genital changes had lower sperm counts.

Elizabeth Salter-Green, director of the chemicals campaign group CHEM Trust, said last night: 'These results are extremely worrying. We now know that phthalates, to which we are all constantly exposed, are extremely worrying from a health perspective, leading to disruption-of male reproduction health and, it appears, male behaviour too.

'This feminising capacity of phthalates makes them true "gender benders". Clearly the boys who have been studied are still young, but reduced masculine play at this age may lead to other " feminised development" in later life.

'This cannot be good news for their long term health and development, or that of our society in general.'

But Tim Edgar of the European Council for Plasticisers and Intermediates said: 'We need to get some scientific experts to look at this study in more detail before we can make a proper judgment.

'However, given the simple approach of the research and the relatively small sample of children, I think these results need to be treated with extreme caution. I don't think anyone should jump to such conclusions without some much more sophisticated research being carried out.'

How to Digitally Record/Video a UFO sighting:

Como registar digitalmente ou gravar um vídeo de um avistamento de um UFO:

Stabilize the camera on a tripod. If there is no tripod, then set it on top of a stable, flat surface. If that is not possible lean against a wall to stabilize your body and prevent the camera from filming in a shaky, unsteady manner.

Estabilize a camera com um tripé. Se não tiver um tripé, então coloque-a em cima de uma superfície estável. Se não for possível, então encoste-se a uma parede para estabilizar o corpo e evitar que a camera registe de maneira tremida e instável.

Provide visual reference points for comparison. This includes the horizon, treetops, lampposts, houses, and geographical landmarks (i.e., Horsetooth Reservoir, Mt. Adams, etc.) Provide this in the video whenever is appropriate and doesn’t detract from what your focus is, the UFO.

Forneça pontos visuais de referência para comparação. Isso inclui o horizonte, cimo das árvores, postes de iluminação, pontos de referência geográficos (como o Reservatório de Horsetooth, Mone Adams, etc) Forneça esses pontos no vídeo sempre que for apropriado e não se distraia do que é o seu foco, o UFO/a Nave.

Narrate your videotape. Provide details of the date, time, location, and direction (N,S,E,W) you are looking in. Provide your observations on the weather, including approximate temperature, windspeed, any visible cloud cover or noticeable weather anomalies or events. Narrate on the shape, size, color, movements, approximate altitude of the UFO, etc and what it appears to be doing. Also include any unusual physical, psychological or emotional sensations you might have. Narrate any visual reference points on camera so they correlate with what the viewer will see, and thereby will be better able to understand.

Faça a narração do vídeo. Forneça pormenores sobre a data, hora, local e direcção (Norte, Sul, Este, Oeste) que está a observar. Faça observações sobre as condições atmosféricas, incluindo a temperatura aproximada, velocidade do vento, quantidade de nuvens, anomalias ou acontecimentos meteorológicos evidentes. Descreva a forma, o tamanho, a cor, os movimentos, a altitude aproximada onde se encontra o UFO/nave, etc e o que aparenta estar a fazer. Inclua também quaisquer aspectos pouco habituais de sensações físicas, psicológicas ou emocionais que possa ter. Faça a narração de todos os pontos de referência visual que o espectador irá ver e que, deste modo, será capaz de compreender melhor.

Be persistent and consistent. Return to the scene to videotape and record at this same location. If you have been successful once, the UFO sightings may be occurring in this region regularly, perhaps for specific reasons unknown, and you may be successful again. You may also wish to return to the same location at a different time of day (daylight hours) for better orientation and reference. Film just a minute or two under “normal” circumstances for comparison. Write down what you remember immediately after. As soon as you are done recording the experience/event, immediately write down your impressions, memories, thoughts, emotions, etc. so it is on the record in writing. If there were other witnesses, have them independently record their own impressions, thoughts, etc. Include in this exercise any drawings, sketches, or diagrams. Make sure you date and sign your documentation.

Seja persistente e não contraditório. Volte ao local da cena e registe o mesmo local. Se foi bem sucedido uma vez, pode ser que nessa região ocorram avistamentos de UFOs/naves com regularidade, talvez por razões específicas desconhecidas, e talvez possa ser novamente bem sucedido. Pode também desejar voltar ao mesmo lugar a horas diferentes do dia (durante as horas de luz)para ter uma orientação e referência melhor. Filme apenas um ,inuto ou dois em circunstâncias “normais” para ter um termo de comparação. Escreva tudo o que viu imediatamente após o acontecimento. Logo após ter feito o registo da experiência/acontecimento, escreva imediatamente as impressões, memórias, pensamentos, emoções, etc para que fiquem registadas por escrito. Se houver outras testemunhas, peça-lhes para registar independentemente as suas próprias impressões, pensamentos, etc. Inclua quaisquer desenhos, esbolos, diagramas. Certifique-se que data e assina o seu documento/testemunho.

Always be prepared. Have a digital camera or better yet a video camera with you, charged and ready to go, at all times. Make sure you know how to use your camera (and your cell phone video/photo camera) quickly and properly. These events can occur suddenly, unexpectedly, and often quite randomly, so you will need to be prepared.

Esteja sempre preparado, Tenha sempre uma camera digital, melhor ainda, uma camera vídeo consigo, carregada e pronta a usar sempre que necessário. Certifique-se que sabe como lidar com a sua camera (ou com o seu celular/camera fotográfica) rápida e adequadamente. Esses acontecimentos podem acontecer súbita e inesperadamente e, por vezes, acidentalmente, por isso, necessita estar preparado.

Look up. Be prepared. Report. Share.

Olhe para cima, Esteja preparado, Relate, Partilhe.
