摘要

地球上没有水就没有生命。由于许多人类活动,例如迅速的商业化、人口的快速增长、缺乏系统的城市规划以及对自然资源的不当利用,水质下降了。本研究评估废水中重金属离子的存在和毒性,旨在了解与工业排放和城市径流相关的环境和公共健康风险。造成水污染扰动率的主要原因是工业废水的排放。人类不断向生态系统排放大量有机和无机污染物。重金属离子(即Ni、Cu、Cr、Pb、Zn、Ar和Hg)对生态系统和动物的有害影响已被环境保护局列为优先污染类别。原子密度超过4000 kg/m3的金属和类金属被认为是重金属。这些有毒金属的存在对人类健康构成重大风险,包括对神经系统、肾脏和其他重要器官的潜在损害,以及对水生生态系统的有害影响。重金属在生态系统内以各种稳定形式持续积累,对环境构成重大威胁。与有机污染物不同,重金属是不可生物降解的,可以长时间留在环境中,在世界范围内造成长期的生态和健康影响。该研究强调了定期监测和有效处理工业废水以减轻重金属污染的迫切需要。实施严格的废物管理做法和采用先进的补救技术是保障环境和公众健康的关键步骤。该研究强调需要加强废水处理战略和更严格的监管执法,以减轻重金属污染,保护水生生态系统和人类健康。

Assessment of heavy metal ion toxicity in wastewater: A comprehensive review

Assessment of heavy metal ion toxicity in wastewater: A comprehensive review
There can be no life on Earth apart from water. Water quality has declined due to many human activities, such as swift commercialization, rapid population growth, a lack of systematic urban planning, and the improper utilization of available resources from nature. This study evaluates the presence and toxicity of heavy metal ions in wastewater, aiming to understand the environmental and public health risks associated with industrial discharge and urban runoff. The main causes of the perturbing rate of water pollution are the release of industrial wastewater. Humans have steadily discharged a vast array of organic and inorganic pollutants into ecosystems. The detrimental effects of heavy metal ions (viz., Ni, Cu, Cr, Pb, Zn and Ar, and Hg) on ecosystems and animals have led to their classification as a priority pollution category by Environmental Protection Agency. More than 4000 kg/m3 of atomic densities of metal and metalloids are considered as Heavy metals. The presence of these toxic metals poses substantial risks to human health, including potential damage to the nervous system, kidneys, and other vital organs, as well as detrimental effects on aquatic ecosystems. Heavy metals pose a significant environmental threat due to their persistence and propensity to accumulate in various stable forms within ecosystems. Unlike organic pollutants, heavy metals are non-biodegradable and can remain in the environment for extended periods, led to long-term ecological and health impacts worldwide. The study underscores the urgent need for regular monitoring and effective treatment of industrial wastewater to mitigate heavy metal pollution. Implementing stringent waste management practices and adopting advanced remediation technologies are crucial steps toward safeguarding environmental and public health. This study underscores the need for enhanced wastewater treatment strategies and stricter regulatory enforcement to mitigate heavy metal pollution and safeguard aquatic ecosystems and human health.

期刊介绍: Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
