概括

经过处理的废水灌显著增加了农业土壤中微塑料 (MP) 的积累,对生态系统构成风险. 这项研究强调了迫切需要解决农业废水中的PM污染问题,特别是在肥沃的地区.

科学领域:

环境科学环境科学
农业科学农业科学
生态毒理学生态毒理学

背景情况:

农业土壤中的微塑料 (MP) 污染日益令人担忧,对可持续农业的潜在影响越来越大.
传统的废水处理厂不充分去除MP,导致它们通过处理废水 (TWW) 灌在土壤中积累.
由于TWW灌,农业生态系统中MP污染存在有限的研究.

研究的目的:

调查TWW灌对土壤中的PM积累TWW灌对农业土壤中的MP积累的影响在Konya,土耳其.
评估PM污染对农业生态系统的潜在风险.
分析土壤物理化学性质和MP水平之间的关系.

主要方法:

在两种深度 (0-10厘米和10-20厘米) 分析了来自TWW灌和控制土地的202个土壤样本.
基于颜色,形状和聚合物类型的量化MP.
使用污染因子 (CF),污染负载指数 (PLI) 和危害指数 (H) 评估MP污染风险.

主要成果:

与对照土壤 (169 ± 46.8 MP / kg) 相比,TWW灌的土壤显示出明显更高的MP计数 (329 ± 139.5 MP / kg在0-10厘米).
纤维,薄膜和碎片是主要的MP类型;透明的MP是最普遍的.
MP污染是显著的 (CF ≥3),在富含有机物和营养的肥沃土壤中风险更高.

结论:

水灌是农业土壤中MP积累的重要来源,增加了环境风险.
科尼亚的农业土壤对于粮食生产至关重要,面临PM污染的风险.
增加废水灌造成的PM污染需要在土壤管理策略中更加关注.

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.

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
