概括

双暴露会伤害印度太平洋的驼背海豚. 双S (BPS) 是普遍存在的,并且比双A (BPA) 具有更高的风险,这表明BPA替代品的潜在问题.

科学领域:

环境毒理学环境毒理学
海洋哺乳动物健康
内分泌干扰干扰内分泌系统

背景情况:

双 (BP) 暴露对脆弱的海洋物种构成风险,例如印度太平洋驼背海豚 (Sousa chinensis).
了解BP形状及其不良影响对于保护工作至关重要.

研究的目的:

为了研究双醇的形状及其对驼背海豚的毒理影响.
评估与各种双相关的风险,包括BPA及其替代品.

主要方法:

在鱼的油脂和脏组织中分析了六种双 (BPA,BPS,BPF,BPAF,BPB,BPP).
在体外研究中使用驼背海豚和人类皮肤纤维细胞来确定灵敏度和毒性 (EC50值).
风险系数 (RQ) 计算用于评估健康风险.

主要成果:

双S (BPS) 是海豚组织中最丰富的双.
油脂的总度明显高于脏和肝脏的总度.
比BPA,BPS的毒性更高,对海豚的健康风险更大.
与炎症相关的BPA暴露;与基因毒性的BPP和BPS.

结论:

双S (BPS) 对驼背海豚的健康风险很大,可能超过BPA.
乙替代品可能会带来类似或更大的风险,需要仔细评估,以避免令人遗憾的替代品.
非侵入性方法可以有效地评估临灭绝的鱼中的双风险.

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...
