Espreitem esta hiperligação:   Contagem de garrafas e vejam a quantidade de garrafas que não são recicladas e que vão parar ao oceano. E reparem no tempo que demora a decomposição do plástico. Uma simples garrafa (PET) demora 700 anos até que comece a decomposição.

Check out this link: Contagem de garrafas and see what happens to the quantity of bottles that are not recycled and that will end up in the ocean. Check also how much time it takes for 1 bottle to decompose. It takes 1 PET plastic bottle 700 years to start decomposing.

BPA

O Bisfenol-A, vulgarmente abreviado de BPA, é uma substancia química que existe em vários tipos de plásticos e aditivos plásticos. BPA é proibido em países como Canadá, Dinamarca e Costa Rica e em alguns Estados norte-americanos.

BPA chemical is found in hard plastics and the coatings of food and drinks cans. BPA is banned from Canada, Denmark, and Costa Rica and in some USA states.

– What are the possible health effects of bisphenol A (BPA) on humans?

  • Reproductive disorders – scientists from Brigham and Women’s Hospital showed that BPA exposure can affect egg maturation in humans.
  • Male impotence – Dr De-Kun Li, a reproductive and perinatal epidemiologist at Kaiser Permanente’s Division of Research in Oakland, California, reported in the journal Human Reproduction that BPA exposure may raise the risk of erectile dysfunction. Sexual desire and problems with ejaculation were also linked to BPA exposure among men.
  • Heart disease (females) – BPA can cause heart disease in women, scientists at the University of Cincinnati found.
  • Heart disease in adults – another US study linked BPA exposure to diabetes and heart disease in adults.
  • Sex hormones in men – an August 2010 study linked BPA exposure to changes in sex hormones in men.
  • Type 2 diabetes – A UK study linked higher levels of urinary BPA to type 2 diabetes, cardiovascular disease and liver-enzyme abnormalities.
  • Brain function, memory, learning – US researchers linked BPA exposure to loss of connections between brain cells in primates, potential problems with memory and learning, as well as depression.
  • Women’s eggs – Californian researchers found that exposure to bisphenol A may affect the quality of a woman’s eggs retrieved for in vitro fertilisation (IVF).
  • Chemotherapy – University of Cincinnati scientists found that BPA exposure may reduce chemotherapy treatment efficacy.
  • Breast cancer – A Yale School of Medicine study found a possible increase in breast cancer risk among females exposed to BPA and DES (Diethylstilbestrol) in the womb.
  • Asthma – A US study suggested a link between increasing asthma rates and a particular threshold of BPA.

Outras opções as garrafas de plástico descartável:

  •          Garrafas reutilizáveis de plástico
  •          Garrafas de Alumínio
  •          Garrafas de aço inoxidável

Other options for disposable plastic bottles:

  • Reusable plastic bottles
  • Aluminium Bottles
  • Stainless Steel Bottles

Pros and Cons

Em relação à ser o mais saudável é a garrafa de aço inoxidável porque não contém químicos que possam contaminar a nossa água, já o Alumínio normalmente é revestido com plástico que contem BPA por isso não deve estar em contacto com a comida ou bebida. As garrafas de plástico reutilizável podem libertar outros químicos mesmo quando é BPA- free devido à exposição de calor ou de estar ao sol.

Em termos de durabilidade a é melhor garrafa é a de Aço inoxidável . O preço da garrafa inox é mais cara do que as outras opções.

The healthiest is the Stainless Steel bottle because it does not contain chemicals that might contaminate our water. Aluminium should not be in contact with food or drink so it is usually coated with plastic containing BPA. Reusable plastic bottles can release other chemicals even when it is BPA- free due to heat or sun exposure.

In terms of durability, the Stainless Steel bottle is better than the others. However, the Stainless Steel bottle is considerably more expensive than the other options.
