大米樣品中發(fā)現(xiàn)有高含量的微塑料

A study out of the University of Queensland has found that rice, particularly the instant variety, has high levels of microplastics in it.

昆士蘭大學(xué)的一項研究發(fā)現(xiàn)，大米，特別是速溶大米，含有大量的微塑料。

All samples in the study contained microplastics, however researchers found a 100 gram serve of instant rice, which undergoes more processing, contained up to 13 milligrams of plastic fragments, Nine News reports.

新聞報道稱，研究中的所有樣品都含有微塑料，然而研究人員發(fā)現(xiàn)，經(jīng)過更多加工的100克速食米飯含有高達13毫克的塑料碎片。

The same quantity of regular uncooked rice contained three to four milligrams of microplastic.

同樣數(shù)量的普通生米含有3到4毫克的微塑料。

While packaging was partly to blame, other processes involved were also identified.

雖然有包裝的因素，但其他過程也不可忽略。

"In the processing of the rice before it gets put into a bag or while it's being grown - so, agricultural processes," Dr Jake O'Brien from the University of Queensland said.

昆士蘭大學(xué)的Jake O'Brien博士說：“在大米被裝入袋中或種植過程中的加工過程中，農(nóng)業(yè)過程也是如此。”。

“Rice is a staple food around the world, so it is important we understand the quantity of microplastics we could be consuming.”

“大米是全世界的主食，因此了解我們可能食用的微塑料的數(shù)量非常重要。”

Microplastics are present in a number of consumable foods such as shellfish, beer, and salt.

微塑料存在于許多消費性食品中，如貝類、啤酒和鹽。

Another 2019 study estimated humans consume about five grams of plastic every week, the equivalent to the weight of a credit card.

另一項2019年的研究估計，人類每周消費約5克塑料，相當(dāng)于一張信用卡的重量。

"At this stage we don't know about any health implications from ingesting microplastics via food consumption but we do know that where there is exposure there is some form of risk," O'Brien said.

O'Brien說：“在現(xiàn)階段，我們不知道通過食物攝入微塑料會對健康產(chǎn)生什么影響，但我們確信，哪里有問題，哪里就會有某種形式的風(fēng)險。”。

“Importantly, we also found washing rice before cooking reduced plastics contamination by 20 to 40 per cent.”

“重要的是，我們發(fā)現(xiàn)，煮飯前洗米可將塑料污染減少20%至40%。”

Researchers tested for seven different plastic types ranging from the most common plastic, polyethylene to plastics used in clothing and food production, laminates, technical engineering, polystyrene, acrylics and tube piping.

研究人員測試了七種不同類型的塑料，包括最常見的塑料、聚乙烯、以及于服裝和食品生產(chǎn)的塑料、層壓板、技術(shù)工程、聚苯乙烯、丙烯酸和管材等。
