概括
为灌再利用经过处理的废水是可持续的,但可能会引入污染物. 用经过处理的废水灌的番茄在水果中吸收了最小的污染物,不构成立即的健康风险,但土壤积累需要监测.
科学领域:
- 环境科学 环境科学
- 农业科学 农业科学
- 食品安全 食品安全
背景情况:
- 用于灌的经过处理的废水 (TWW) 再利用是一种可持续的水资源管理策略.
- 人们担心,粮食作物和食物链可能受到新兴关注污染物 (CEC) 的污染.
研究的目的:
- 评估27种CEC在不同灌方案下在田间条件下在番茄植物中的吸收和转移.
- 评估与食用用TWW灌的番茄有关的潜在人类健康风险.
主要方法:
- 使用四种灌处理的实地实验:饮用水 (PW),TWW,加的PW和加的TWW (1 mg/L CEC).
- 在番茄果实,根,叶子和茎中分析CEC.
- 评估水果产量和饮食暴露的估计.
- 长期土壤分析为CECs.
主要成果:
- 在TWW中,CEC的稳定性低于PW,影响了吸收.
- 在没有的条件下,番茄果实中CEC的最小生物积累 (TWW只检测到碳胺).
- 在尖的条件下,在水果中检测到几种CEC,在根,叶和茎中度更高.
- 水果产量没有受到影响,饮食暴露估计低于风险值.
- 土壤分析表明,CEC积累量 (亚胺素,三碳) 在灌后的30个月内超过了安全值.
结论:
- 用TWW灌的番茄的消费不会带来直接的饮食风险,因为水果中CEC的积累最小.
- 在用TWW灌的农田土壤中长期积累CEC需要持续监测以确保环境安全.

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.

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...
