Occurrence and Exposure to Lead and Cadmium and Their Environmental Influence on Eyesight

Abstract

Heavy metal influence on the environment and humans is well known, although not all aspects are fully understood. Increased manufacturing and industrial growth without any proper approach for usage, distribution, and storage of heavy metals might lead to a very dangerous influence not only on an entire ecosphere, but also might affect human health. Because of different forms of exposure to heavy metals, different forms of after-exposure diseases might appear. Exposure by air, water, direct contact, and even by consumption -along with other less common ways of exposure -have been mentioned globally [1].Soil and water exposed to heavy metals results in both animal and plant metal poisoning. Humans at the end of the food chain are exposed on any long-or short-term influence of heavy metal poisoning [2]. Many variables are related to poison activity on humans and the environment. Factors such as age, coexisting other diseases, and time and type of exposure are very important. Different topics are related to the environment. Type of soil, insolation, and closure to any human habitats and other factors should always be considered when discussing heavy metal exposure. Accumulation of heavy metals is dangerous for the environment. A special focus should be particularly used in order to avoid improper heavy metal disposal and increase a safe and long-term method for waste storage [3]. In order to fully understand the impact of heavy metals on humans and the environment is unlikely to improve factory production and safety standards [4].Evaluate and describe briefly how lead and cadmium heavy metal exposure influences the sight organ and discuss whether it is a common or rare occurrence.Pol. J. Environ. Stud. Vol. 24, No. 4 (2015) AbstractNowadays heavy metals in the environment and everyday life are very common. Their usage and influence in industry is essential. Quite often not only the environment but also general human health might be impacted by their use and presence. Metal poisoning and its effect on living structures and tissues impacts their condition. The environment and every living species in it are heavily vulnerable to any heavy metal exposure and might lead to catastrophic natural disasters. In humans skin irritations and general diseases are not so common, but they do appear, and everyone should be aware of this. In this paper we focus on a very special topic related to heavy metal exposure to eyesight and their influence on this important organ. Lead and cadmium are the most common heavy metals used almost everywhere.

Health Problems Among Workers Who Recycle Electronic Waste in Southern Thailand

“…In this study, blurred vision occurred in 26.8% of e-waste recycling workers. This result supports previous findings [20,21], which reported the effects of heavy metal (lead, cadmium and manganese) intoxication on eyesight. In addition, mercury has been reported to be significantly associated with dry eye disease [22].…”

Investigating the Ameliorative Potential of the Aloe barbadensis Aqueous Fraction on Oxidative Stress Markers and Biochemical Parameters in Cadmium-Intoxicated Rabbits

“…The study protocols were approved (18 June 2014) by the Advance Studies and Research Board (AS&RB) of the University of the Punjab, Pakistan. Experimental protocols were in agreement with the National Institute of Health (NIH) guidelines for the care and use of laboratory animals [2]. Body weights were recorded every four days until the end of the experiment.…”

“…Several results of various studies have also proved the protective effects of plants extracts on cadmium-induced hepatotoxicity [2,[35][36]. …”

“…Thus an ample opportunity for exposure to cadmium is possible in and outside the workplace [1][2]. Concentrations of Cd in the surrounding environment are increasing due to its diverse sources and prolonged biological half-life of 10-30 years.…”

Facile and simple synthesis of triethylenetetramine-modified mesoporous silica adsorbent for removal of Cd(II)

“…The weak response of cells and comparatively long halflife of 10 to 30 years for Cd(II) ions in living organs indicates that it is highly non-biodegradable and toxic. Cd(II) exposure causes renal disorder, osteoporosis, neurological malfunction, cancers, genetic toxicity, endocrine damage and fertility problems for human being [3,4]. Therefore, it is highly important to develop procedures for the treatment of cadmium-contaminated industrial wastewater before being discharged into the environment.…”
