概括

这项研究评估了中国的室内增塑剂,发现了广泛的污染. 虽然酸盐增塑剂 (PAE) 占主导地位,但非酸盐替代品 (NPAE) 正在增加,东北部和城市地区的含量更高.

科学领域:

环境化学环境化学
毒理学毒理学毒理学
公共卫生公共卫生

背景情况:

关于非酸盐增塑剂 (NPAE) 和中国室内环境中人类暴露风险的数据有限.
增塑剂是室内材料中常见的添加剂,可能会引起健康问题.

研究的目的:

进行全国范围的甲酸盐 (PAE) 和非甲酸盐增塑剂 (NPAE) 在中国各地家用灰尘中的污染的评估.
评估室内环境中与这些增塑剂相关的人类暴露风险.
为了确定塑化剂污染的趋势和地理差异.

主要方法:

对11个PAE和16个NPAE的全国374个室内尘埃样本进行分析.
总塑化剂度的量化 (27塑化剂).
对PAE发生的时间分析 (2007-2023) 和地理分布分析.

主要成果:

在27种塑剂中,有19种被广泛检测到,其中27种塑剂的中位数为226μg/g.
聚乙烯构成了整体塑化剂的70%以上,但一些NPAE显示出显著的水平.
中国东北部和城市家庭的污染率较高;随着时间的推移,PAE的下降趋势被观察到.
地板和住房材料被确定为主要污染源.

结论:

中国的室内环境广泛受到PAE和NPAE的污染,NPAE的流行率越来越高.
污染水平存在地理和人口差异,中国东北部和城市环境的度更高.
虽然目前的健康风险似乎很小,但对复杂的暴露途径的进一步研究是明智的监管政策的必要条件.

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Determining the pH of Salt Solutions

Determining the pH of Salt Solutions

The pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations form a solution with a pH less than 7. For example, in ammonium nitrate (NH4NO3) solution, NO3− ions do not react with water whereas NH4+ ions produce the hydronium ions resulting in the acidic solution. In contrast, salts that contain pH-neutral cations and the hydroxide ion-producing anions form a solution with a pH greater than 7.

iChip

iChip

The cultivation of environmental microorganisms has long been hindered by the inability to replicate complex native conditions in vitro. The isolation chip (iChip) addresses this limitation by facilitating the growth of previously uncultivable microorganisms through in situ incubation. Designed for high-throughput microbial cultivation, the iChip comprises hundreds of microchambers, each capable of housing a single microbial cell. These microchambers are loaded with a mixture of molten agar and...
