Study Finds 'Smokeless' Fuels Release Tiny Particles That Can Harm Lung Health

研究发现“无烟”燃料会释放可能损害肺部健康的微小颗粒

A new study has revealed that smokeless fuels may not be as safe as people believe.

一项新研究显示，无烟燃料可能不如人们所相信的那样安全。

Researchers discovered that burning these fuels produces large amounts of ultrafine particles.

研究人员发现，燃烧这些燃料会产生大量的超细颗粒物。

These particles are so tiny that they can travel deep into people's lungs and cause serious health problems.

这些微粒非常微小，以至于它们可以深入人们的肺部并导致严重的健康问题。

Smokeless fuels are sold as cleaner alternatives to coal, wood, and peat for home heating.

无烟燃料作为煤炭、木材和泥炭的更清洁替代品出售，用于家庭供暖。

Many people have chosen these fuels because they are expected to improve air quality.

许多人选择了这些燃料，因为它们被预期能改善空气质量。

However, the research team at the University of Galway found something surprising during their tests.

然而，高威大学的研究团队在测试过程中发现了一些令人惊讶的事情。

The discovery was accidental.

这项发现是偶然的。

Scientists were testing different fuels in both traditional and modern stoves.

科学家们当时正在传统和现代的炉灶中测试不同的燃料。

As expected, smokeless fuels produced less visible smoke than wood or coal.

正如预期的那样，无烟燃料产生的可见烟雾比木材或煤炭少。

#11

But for each kilogram burned, these fuels released two to three times more ultrafine particles.

但每燃烧一公斤，这些燃料释放出的超细颗粒物是原来的两到三倍。

#12

The tiny size of these particles means they can become deposited deep in the lungs.

这些微粒极小的尺寸意味着它们可能会沉积在肺部深处。

#13

Professor Jurgita Ovadnevaite, from the University of Galway, explained the results.

来自高威大学的 Jurgita Ovadnevaite 教授解释了研究结果。

#14

"No one had considered that less smoke could lead to an increase in ultrafine particles."

“没有人考虑过较少的烟雾可能会导致超细颗粒物的增加。”

#15

"We did not expect such a strong effect until we saw the data."

“直到我们看到数据，我们才预料到会有如此强烈的影响。”

#16

Doctor Chunshui Lin, who also worked on the study, added that the team spent nearly two months burning fuel samples every day to check the data quality.

同样参与这项研究的林春水博士补充说，团队花了将近两个月的时间每天燃烧燃料样本，以检查数据质量。

#17

After the laboratory findings, the researchers went back to check outdoor air measurements in Dublin and the town of Birr in Ireland.

在实验室得出发现后，研究人员回到爱尔兰的都柏林和比尔镇检查室外空气测量值。

#18

They wanted to understand how ultrafine particles from smokeless fuels affect local air quality.

他们想要了解来自无烟燃料的超细颗粒如何影响当地的空气质量。

#19

This research suggests that toxic substances in these fuels need more attention.

这项研究显示，这些燃料中的有毒物质需要更多的关注。

#20

Experts now believe that regulations on smokeless fuels should be updated to protect lung health.

专家们现在认为，无烟燃料的法规应该进行更新，以保护肺部健康。

片语表 (8 个片语)

片语包含类型标示、双语定义、用法说明和例句。

lead to

phrasal verb

to result in or cause something to happen

导致、引起

解释： 用于描述一个行动或情况如何产生特定的结果，常用于因果关系的陈述。

范例： No one had considered that less smoke could lead to an increase in ultrafine particles.

air quality

collocation

the degree to which the air is clean or polluted

空气质量

解释： 这是一个环境科学中的常见搭配词，用来衡量空气的干净程度。

范例： Many people have chosen these fuels because they are expected to improve air quality.

go back

phrasal verb

to return to a place, subject, or activity

回到、重新查看

解释： 在文中指研究人员重新检视之前的数据或回到特定的地点进行后续研究。

范例： The researchers went back to check outdoor air measurements.

as expected

idiom

in the way that was planned or thought likely to happen

正如预料、不出所料

解释： 用来确认某事发生的方式与之前的预测或期望一致。

范例： As expected, smokeless fuels produced less visible smoke than wood or coal.

ultrafine particles

technical term

Particles with a diameter of less than 0.1 micrometers, often resulting from combustion.

超细悬浮微粒

解释： 在日常英语中，"fine" 通常表示“好的”或“健康的”。但在科学语境中，"fine" 指的是“微小的”。"Ultrafine" 则是一个专业术语，指直径小于 0.1 微米的极微小颗粒（比常见的 PM2.5 更小）。

范例： Ultrafine particles are particularly dangerous because they can enter the bloodstream.

deposited

technical term

To settle or accumulate in a specific place through a natural or physical process.

沉积 / 堆积

解释： "Deposit" 最常见的日常用法是“银行存款”或“支付押金”。但在生物学或医学中，它描述物质（如微粒、脂肪或矿物质）停留在身体组织或器官内部的物理过程。

范例： Cholesterol can be deposited on the walls of the arteries.

fuel samples

technical term

A small amount of a substance taken to be tested or analyzed in a laboratory.

燃料样本 / 试样

解释： "Sample" 在日常生活中常指“试用品”或“范例”。在科学研究中，它专指为了进行实验、化验而采集的“检体”或“试样”。

范例： The researchers collected water samples from the river to test for pollution.

air measurements

technical term

Data points or readings collected by sensors to determine the concentration of pollutants in the atmosphere.

空气监测数据 / 测量值

解释： "Measurement" 通常指长度、宽度或重量的测量。在环境科学中，"air measurements" 指的是对空气中各种化学物质或微粒浓度的“监测数据”或“读数”。

范例： The city's air measurements showed a spike in nitrogen dioxide levels.
