The documentation of lead toxicity (plumbism) dates back to the times when man learnt its various applications. This versatile heavy metal is non-degradable and its ability to get accumulated in the body that goes undiagnosed, makes it a serious environmental health hazard. Lead is now known to affect almost every organ/tissue of the human body. With irreversible effects on neurobiological development of young children and foetus, its toxicity has lasting implications on the human life. Outlining the symptoms, diagnosis and treatment therapy for lead poisoning, the present review elaborates the pathophysiological effects of lead on various organs. This will be of immense help to the health professionals so as to inculcate a better understanding of the lead poisoning which otherwise is asymptomatic. With chelation therapy being the classic path of treatment, new strategies are being explored as additive/adjunct therapy. It is now understood that lead toxicity is completely preventable. In this regard significant efforts are in place in the developed countries whereas much needs to be done in the developing countries. Spreading the awareness amongst the masses by educating them and reducing the usage of lead following stricter industry norms appears to be the only roadmap to prevent lead poisoning. Efforts being undertaken by the Government of India and other organisations are also mentioned.
铅中毒(铅毒症)的记录可以追溯到人类了解其各种用途的时代。这种用途广泛的重金属不可降解,且其在体内蓄积而未被诊断出来的情况,使其成为严重的环境健康危害。现在已知铅几乎会影响人体的每个器官/组织。由于对幼儿和胎儿的神经生物学发育有不可逆的影响,其毒性对人类生活有持久的影响。本综述概述了铅中毒的症状、诊断和治疗方法,阐述了铅对各个器官的病理生理影响。这将对健康专业人员有极大帮助,以便更好地理解铅中毒,否则铅中毒是没有症状的。螯合疗法是经典的治疗途径,目前正在探索新的策略作为辅助/附加疗法。现在人们明白铅中毒是完全可以预防的。在这方面,发达国家正在做出重大努力,而发展中国家还有很多工作要做。通过教育群众提高认识,并按照更严格的行业规范减少铅的使用,似乎是预防铅中毒的唯一途径。文中还提到了印度政府和其他组织正在做出的努力。
