まとめ
アラブ首長国連邦のホークスビルカメの卵は 有機塩素殺虫剤と多環芳香炭化水素を大量に含んでいます これらの発見は海洋汚染の懸念を強調し,アラビア湾の生物指標としてカメを提案しています.
科学分野:
- 海洋生物学
- 環境化学
- 保護科学
背景:
- ホークスビルの海は サンゴ礁の健康に不可欠であり 環境条件を指示します
- 海洋汚染は絶滅危惧種と生態系の整体性を脅かしています
研究 の 目的:
- ホークスビルの海の卵におけるポリサイクル芳香炭化水素 (PAH) とオーガノクロリン農薬 (OCP) の濃度を評価する.
- アラブ湾の海洋汚染のバイオインディケーター種としてのホークスビルの可能性を評価する.
主な方法:
- アラブ首長国連邦のサー・ブー・ナイル島で 化していないホークスビルの卵の28個のクラッチを分析した.
- QuEChERを用いた持続性有機汚染物質 (POP) の抽出,その後d-SPEとガス染色体質量分析 (GC/MS) を行う.
主要な成果:
- 100%の卵 (183.91 ± 39.19 ng/g) に有機塩素農薬 (OCP) が検出され,ポリサイクル芳香炭化水素 (PAH) の濃度 (64.24 ± 14.35 ng/g) を上回った.
- DDTとメタボリテッドが流行しており,持続的な汚染を示しています.
- 低分子量PAHが優勢で,石油源を示唆しています.
結論:
- ホークスビルの卵は PAHsとOCPsで汚染されています
- この研究は,アラビア湾のPAHとOCPをモニタリングするためのバイオインディケーター種としてホークスビル海の使用を支持しています.
- 地域における産業と沿岸開発の拡大による海洋汚染に対処するために,緊急の緩和戦略が必要である.

Physical Properties of Amines
3.2K
Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

Types of Toxins
3.7K
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.

Prevention of Further Absorption of Poison
1.4K
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Drug Toxicity: Overview
313
Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...

Toxicity Testing in Animals
222
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
