概括

硫化物 (H₂S) 来自分解的体对海游客构成的风险最小. 然而,清理工人可能面临显著的H₂S暴露,近四分之一的读数超过5ppm.

科学领域:

环境科学环境科学
海洋生物学海洋生物学
公共卫生公共卫生

背景情况:

自2011年以来,全方位的萨尔加索姆浮动已经影响了30多个大西洋国家.
体分解释放硫化 (H2S),这种气体在高度下可能有害.
了解H₂S的变异性对于评估沿海人口的健康风险至关重要.

研究的目的:

调查海上腐烂的石灰岩排放的H2S的时间和空间分布.
评估当地居民,游客和清洁工人潜在的H2S暴露风险.

主要方法:

使用SENKO传感器监测硫化 (H₂S) 的水平.
从Sargassum堆中进行了四个距离 (0,10,30,40米) 的测量.
监测发生在墨西哥莫雷洛斯港,整个2022年和2023年.

主要成果:

在石堆下检测到高H2S度 (偶尔超过100ppm),其中23.5%的读数超过5ppm.
随着距离海岸的距离,H2S水平显著下降,在30-40米处降至0.1ppm以下.
H2S度与石灰堆高度,子堆温度和风速有正相关性.

结论:

对于居民或游客来说,没有发现显著的即时H₂S暴露风险.
石灰尘清理工人面临着更高的风险,他们的工作时间大约25%的时间可能超过5ppmH₂S.

The Sulfur Cycle

The Sulfur Cycle

Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
