概括

暴露于 (Pb) 的蜜蜂显示蛋白质含量和催化酶活性降低. 用蜜蜂面包补充他们的饮食可以提高对这种重金属污染的耐受性.

科学领域:

环境毒理学环境毒理学
蜜蜂养殖科学蜜蜂养殖科学
授粉者健康授粉者健康

背景情况:

重金属污染,特别是 (Pb),对生态系统和授粉者构成重大全球威胁.
工业使用增加了蜜蜂 (Apis mellifera L.) 的风险,Pb毒性主要导致氧化应激.

研究的目的:

评估摄入对蜜蜂工人的毒性和次致命影响.
在不同的营养条件下,研究Pb对蛋白质含量,酶 (CAT) 活性,脂肪含量和脂肪酸 (FA) 概况的影响.

主要方法:

确定了蜜蜂Pb2+的中位致命剂量 (LD50).
进行了慢性暴露测试,使用亚致死的Pb剂量,不同的蜜蜂饮食 (含糖食物与蜜蜂面包).
在暴露蜂群中分析了蛋白质含量,CAT活性,脂肪含量和FA概况.

主要成果:

的LD50大约为15.13μg Pb2+/bee.
15微克Pb2+的亚致命剂量降低了食含糖饮食的蜜蜂的生存率,但蜜蜂面包补充剂提高了Pb耐受性.
暴露降低了CAT活性,并对体内蛋白质产生了负面影响,无论饮食如何,而FA概况则随着营养质量而变化.

结论:

营养显著影响蜜蜂对诱导毒性的耐受性.
蜜蜂面包补充剂对蜜蜂的次致命暴露提供了保护作用.
会对蜜蜂蛋白质含量和CAT活动产生负面影响,这凸显了营养策略对减轻环境毒素影响的重要性.

关键词:

催化酶酶的催化酶是一种酶.脂肪酸是一种脂肪酸.重金属是一种重金属.蜜蜂是蜜蜂,它们是蜜蜂.(Pb) 是一种.

Toxic Reactions: Overview

Toxic Reactions: Overview

When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

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...

The Periodic Table and Organismal Elements

The Periodic Table and Organismal Elements

Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.
