Solar defenders protect the skin, but not the environment: how to choose?
It is essential to apply sunscreen to prevent radiation – as a result solar burns, premature aging and skin cancer. If the skin is protected on one side, the water organisms in the food chain can affect.

The bath period begins this Sunday, more than 30ºC with maximum temperatures in different parts of the country. Sunscreen use is indispensable, as it is known to everyone to extend the body to the sun. However, not all the defenders are the same: you should read the label and protect the skin and the environment.
“Sunscreens are a set of chemicals and man -made compounds to protect the skin. Any compound created by a man in the environment is not the benefit of the manner, everyone has a negative impact, although in different actions “.
The agency Lusa heard, the biologist described it Sunscreen is not dangerous to the environment. There is a belief that inorganic (minerals) are less aggressive in the environment than organic (chemicals), but it may be some less bad, although “it is not so.”
Chemicals to prevent
It is important to read labels: chemicals OxibenzonaEndocrine is also known as relaxation, and Octinoxato They are especially harmful compounds for water organisms.
Most studies show it Oxibenzona causes coral bleaching, which occurs when the polyps colonies that form coral are expelled when they are expelled.
I guess it The sunscreen between six to 14,000 tons, one to 10% of the oxybenzone, is released in coral reef areas every year.
Studies cited Eva Easiguze indicate on the French Atlantic coast In the back of Hawaii, the back of the Hawaii has released more than eight pounds of protective creams per day (it is banned solar defenders with oxybzone and octinoxate) 36 kg per day, and in the Mexican Caribbean, about 230 tonnes of rescuers burn.
In an interview with Lusa, Environment Engineer Rita Mucio, Nova FCT and Mare researcher will leave another number: “35 kg of compounds will be released on the beach with a thousand visitors.”
The food chain is also affected
Nova FCT Professor and Mary Researcher, Expert in Marine Pollution, Marta Martins and Master Coordinator Ecotoxicology at Marine Living Resources. Studies that indicate that protective compounds affect water organisms, for example reproductive, central nervous system or liver level.
And then, adds, These may also have effects on the microega and plankton, which affects the food chain, which is a childhood larvae and fish.
Rita Mouricio explained it If a (bio -operative) ammo supplies excessive density and managing it, it is already a human being for placement on the skin.
Solar defenders Zinc oxide and titanium oxide can enter the food chain: these nanoparticles are not mobilized by humans, but through water organisms, like microplastics.
The effects of nanoparticles are not yet known, but the expert recalls that there are effects that arise there or even in future generations.
Chemicals always end in the sea (even if you don’t go to the beach)
Solar defenders are taken to the sea When people are swimming, but when they are absorbed by the skin, they go out in the urine and feces and are released by sewage purification centers (WWTP).
WWTP is not only designed to retain these types of compounds They end in rivers and oceans.
So, he explained, Sea organisms are affected in two ways: directly on sunny days through the waste of the bathtubs, and indirectly the WWTP will not filter the year -round.
Marta Martines argued that the defenders should be prioritized with less toxicity or toxic zero. And is considered “A little dizzy” is expensive than solar protectors with low -level pollution.
A. Application, Cavit, is not in danger. The danger is the options. “But only a citizen with information can make options.”
How to properly apply sunscreen?
In addition to the care of the environment that is harmful to the environment, you need to select the solar system:
Regardless of Skin Tone, With at least 30 factors protection, it is recommended to be a step Largo protector (UVA and UVB, two types of ultraviolet radiation)And restore its application every two hours.
Children and mild -scinded individuals, in cases of skin cancer or high UV radiation, should always use the protection index 50 or more.
Even when it is cloudy, the sunlight is low and the temperature is not so high, UV radiation crosses clouds and is equally harmful to health.
And in the winter it is also necessary to use a protector in exposed areas, as cumulative sunlight contributes to lifetime skin loss.
