Description

페트병에 장착되는 여과장치{Filtration device mounted on PET bottles}Filtration device mounted on PET bottles

개시되는 내용은 페트병에 장착되는 여과장치에 관한 것으로, 더욱 상세하게는 생수 페트병의 입구에 결합되어 음용시 물속의 미세플라스틱 입자를 제거하도록 하는 페트병에 장착되는 여과장치에 관한 것이다. The present disclosure relates to a filtration device mounted on a PET bottle, and more particularly, to a filtration device mounted on a PET bottle coupled to an inlet of a bottle of bottled water to remove microplastic particles in water during drinking.

본 명세서에서 달리 표시되지 않는 한, 이 섹션에 설명되는 내용들은 이 출원의 청구항들에 대한 종래 기술이 아니며, 이 섹션에 포함된다고 하여 종래 기술이라고 인정되는 것은 아니다.Unless otherwise indicated herein, the contents described in this section are not prior art to the claims of this application, and inclusion in this section is not admitted to be prior art.

근래에는 음용수를 포장하여 시중에 판매하여 왔다. Recently, drinking water has been packaged and sold on the market.

즉 생수가 담긴 페트병을 마트에 구비하여 소비자가 원하는 상품을 사먹을 수 있도록 하였다.In other words, a PET bottle containing bottled water was provided at the mart to allow consumers to buy the desired product.

한편 근래 가장 문제가 되는 오염물질 중 하나는 미세플라스틱이다. 이는 지구상에 버려진 플라스틱이 분해되면서 미세한 입자로 방출되고 이 미세플라스틱이 동식물에 흡수되거나 토양에 스며들어 빗물과 함께 지하까지 유입될 수 있다.Meanwhile, one of the most problematic pollutants in recent years is microplastics. It breaks down the plastic discarded on Earth and releases it as fine particles, which can be absorbed by plants and animals or seep into soil and enter underground with rainwater.

지하수에 유입된 미세플라스틱은 눈에 보이지 않을뿐 시판 생수의 수원지에도 잔존하고 있으므로 결국 이 생수를 사먹는 소비자가 마시게 되어 인체에 축적될 수 밖에 없어 건강을 위협하는 문제를 야기하게 된다. The microplastics introduced into the groundwater remain invisible and remain in the source of commercially available bottled water, so consumers who buy the bottled water eventually have to drink and accumulate in the human body, causing health problems.

미국 비영리매체 `오브미디어` 의뢰를 받아 미국, 중국, 인도, 태국, 브라질, 인도네시아, 케냐, 레바논, 멕시코 등 9개국에서 판매되는 11개 브랜드 생수 259개를 대상으로 연구를 진행한 결과, 에비앙·아쿠아피나·산펠레그리노 등 조사 대상 생수 중 93%에서 미세플라스틱이 발견됐다.Based on the US non-profit media 'Obmedia', we conducted research on 259 bottles of 11 brands sold in nine countries including the United States, China, India, Thailand, Brazil, Indonesia, Kenya, Lebanon, and Mexico. Fine plastics were found in 93% of the bottled water, including Aquapina and San Pellegrino.

생수에서 발견된 미세플라스틱 크기는 다양하다. 조사에 따르면 한 통의 생수병에서 최대 1만개의 플라스틱 조각이 발견된다.Microplastic sizes found in bottled water vary. Research has found up to 10,000 pieces of plastic in one bottle of mineral water.

미세플라스틱의 크기는 100㎛(1㎛는 100만분의 1m)크기 입자가 ℓ당 평균 10.4개 검출되는 것으로 조사되었다. The size of the microplastics was found to be detected on average 10.4 particles per liter of 100㎛ (1㎛ 1m / 1m) size particles.

머리카락 두께가 대략 50~100㎛인 만큼 이 정도 크기의 미세플라스틱은 육안으로 분간할 수 없는 초미세 입자다. As the hair thickness is about 50 ~ 100㎛, microplastics of this size are very fine particles that are invisible to the naked eye.

동물 실험에 따르면 바다로 유입된 미세플라스틱에 노출된 해양 생물은 성장이 더디거나 생식 능력에 문제가 발생하는 것으로 확인됐다. Animal experiments have shown that marine organisms exposed to microplastics that enter the sea are slow to grow or have reproductive problems.

플라스틱에서 발생하는 발암물질에 노출되면 정자 수 감소, 자폐증 등이 발생할 수 있다는 보고도 있다. Exposure to plastic carcinogens has been reported to reduce sperm count and autism.

미국 조지아공대가 2016년 학술지 `사이언스`에 발표한 논문에 따르면 미세플라스틱에 노출된 치어는 성장 속도가 느려질 뿐 아니라 뇌 손상도 발생해 포식자를 만나도 제대로 피하지 못하는 것으로 나타났다. According to a paper published by the Georgia Institute of Science in 2016, Science revealed that fry exposed to microplastics not only slowed their growth rate but also caused brain damage, which prevented them from avoiding predators.

이렇게 쌓인 미세플라스틱은 먹이사슬을 거쳐 결국 인간에게 되돌아올 수밖에 없다.The accumulated microplastic is forced to return to humans through the food chain.

생수에 들어 있는 미세플라스틱을 포함해 인류가 쓰고 버린 플라스틱은 강을 비롯해 호수, 바다 등으로 흘러 들어가는데 플라스틱이 자연 분해되는 데 수백 년이 걸린다는 점에서 심각한 위협이다. Plastics thrown away by mankind, including microplastics in bottled water, run into rivers, lakes, and seas, making it hundreds of years to decompose naturally.

해양 환경으로 유입되는 플라스틱 폐기물 양은 매년 800만t에 이르는 것으로 추산된다. 완전 자연 분해되기 전에 플라스틱은 강, 바다 등을 떠다니며 물리·화학적 작용을 거쳐 분해돼 점점 작은 플라스틱이 된다. The amount of plastic waste entering the marine environment is estimated to reach 8 million tonnes per year. Before fully decomposed, plastic floats in rivers, seas, etc., and breaks down through physical and chemical processes into smaller plastics.

양식장에 띄워 놓는 공 모양의 스티로폼이 2.5㎜ 크기로 분해되면 약 700만개의 미세플라스틱이 생성된다. When the ball-shaped styrofoam in the farm is decomposed to 2.5 mm, about 7 million microplastics are produced.

미세플라스틱이 해양생물에 어떤 영향을 미치는지를 연구한 결과 생수에서 발견된 미세플라스틱을 섭취하더라도 건강한 성인들은 큰 문제가 안될 것처럼 보이지만 동물 실험 결과에 따르면 부정적인 영향을 배제할 수 없는 상황이다. Investigating the effects of microplastics on marine life, healthy adults may not be a problem even if they consume microplastics found in living water, but animal studies show that negative effects cannot be ruled out.

영유아나 면역력이 약한 사람에게는 부정적인 영향을 미칠 수도 있다며 미세플라스틱의 인체 영향에 대한 방지책이 필요하다. Infants and children with weak immunity may have a negative effect on the need for measures to prevent microplastic effects on the human body.
