概括

塑料袋政策,如禁令和税收, 显著减少海上的塑料垃圾. 这项研究显示,在有政策的地区,在清理过程中发现的塑料袋数量减少了25-47%.

科学领域:

环境科学
保护生物学
环境政策

背景情况:

塑料污染对海洋和淡水生态系统构成重大威胁.
塑料袋政策 (禁令和税收) 在减少塑料垃圾方面的有效性尚不清楚.

研究的目的:

评估塑料袋政策对海岸线塑料垃圾的影响.
提供这些政策在减轻污染方面的有效性.

主要方法:

我们利用了来自美国45,067个海岸线清理的公民科学数据.
分析了在不同地理范围内实施的不同塑料袋政策的数据.

主要成果:

塑料袋政策减少了25%至47%的塑料袋作为收集的垃圾总量的比例.
与单独的禁令相比,塑料袋税可能会进一步减少海岸线垃圾.

结论:

塑料袋政策在缓解海岸线塑料污染方面是有效的.
这些发现支持实施塑料袋政策, 打击水生环境中的塑料垃圾.

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.

Plasticizers

Plasticizers

Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...
