概括

新兴污染物如双甲 (BPA),三三 (TCS) 和三三 (TCC) 在印度水域和鱼类中进行了研究. 虽然BPA很少见,但TCS和TCC在水和鱼中被发现,突出了水生污染风险.

科学领域:

环境化学环境化学
生态毒理学生态毒理学
公共卫生公共卫生

背景情况:

新出现的令人担忧的污染物,包括双甲 (BPA),三三 (TCS),甲基三三 (MeTCS) 和三三 (TCC),由于广泛使用和内分泌干扰潜力,构成风险.
在印度多样化的内陆水生系统 (水和鱼类) 中对这些化合物的现有研究是有限的,造成了显著的知识差距.
早期性成熟,生殖器损伤和生态系统破坏等不良影响需要全面监测.

研究的目的:

调查BPA,TCS,MeTCS和TCC在地表水和来自印度各个内陆水生环境的鱼类中的空间分布.
为了解决印度水生生态系统中这些微污染物数据的稀缺性.
为风险评估和污染管理提供统一的数据集.

主要方法:

从印度各地的河流,水库,洪水平原和污水养湿地收集的地表水和鱼样的分析.
使用分析技术检测和量化BPA,TCS,MeTCS和TCC残留物 (摘要中没有详细说明).
评估不同水生环境和物种中污染物的发生和度.

主要成果:

双A (BPA) 大多未被检测到,除了来自卡弗里河的鱼类 (8.25%阳性).
特里克洛桑 (TCS) 和特里克洛卡班 (TCC) 在科尔卡塔东部的污水养湿地 (分别为83.06%和48.41%的水样) 显示出显著的污染.
洪水平原湿地鱼有相当大的TCS (高达0.69μg/g) 和TCC (高达1.24μg/g),以及MeTCS,尽管无法检测到水残留物. 卡弗里河鱼也显示出广泛的TCS,MeTCS和TCC污染.

结论:

该研究证实了TCS,TCC和MeTCS在印度内陆水生生态系统中的存在,特别是在鱼类中,这表明了重要的生物积累.
污水养的湿地和河流系统被确定为这些污染物的热点.
调查结果强调需要有针对性的风险评估,改进污染管理和政策干预,以保护水生动物健康和公共福祉.

Environmental Applications of Microorganisms

Environmental Applications of Microorganisms

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...

Types of Toxins

Types of Toxins

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

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.
