Metal pollution whether it is in soil, water or air will be taken up by plants and animals and therefore will become part of our daily food (and might even become more concentrated at the end of the foodchain). They found that the composition of the contamination was closely related to specific industries and the changes over time did directly reflect changes in regulations and laws. Spatial (di!erent regions of Korea) and temporal changes (over several years) of the pollution of nine heavy metals were analyzed by Kwon and colleagues (2014)3. It emphasizes some general guidelines to reduce the lead exposure and to improve the situation. ![]() Their overview also defines the impact of pre- and postnatal exposure and the special situation in children. air, water, food, medication) for the population in Iran are analyzed by Karrari and co-workers (2012)2. They also review the transport media (soil, biota, water and air) and how the particle diameter influences the distribution of such particles worldwide. Csavina and co-workers (2013)1 recapitulate how metal particles (lead, arsenic and cadmium) in the dust, which are generated by local mining operations, travel around the world. The articles highlight how some local events might impact the health even at the other side of the globe. The QScience Collection, entitled ‘Metal compounds in our environment and their implications on human health’ highlights recent open access publications that illustrate the current reflection of these issues. Contamination will a!ect air, soil and water (and the food produced) not only locally but also worldwide. Some specific or a perfect blend of potent phyto-constituent(s) from curry leaves can be suggested for or adapted as alternative medicine or integrative medicine for preventing or treating or curing or protecting against heavy metal-induced occupational health hazards.Įditorial Recent updates on metal compounds in our environment and their implications on human health Dietrich Büsselberg Weill Cornell Medical College in Qatar, Qatar Foundation – Education City, POB 24144, Doha, Qatar email: All living organisms (including humans) depend on an intact environment. They have no reported cytotoxic or adverse side effects, if not over consumed. The heavy metals induce generation of ROS and the phyto-components have the potential to scavenge those and boost the body's endogenous antioxidant system. ![]() Most of the synthetic conventional drugs which are extensively prescribed by clinicians for treatments of these diseases have adverse side effects and potent cytotoxicity. Many of the symptoms complained by those industry workers are hardly recognized to be related to occupational exposure to heavy metals, often unidentified as occupational health hazards with a story of metal induced oxidative stress beneath their etiology. Certain physiological, biochemical and behavioural dysfunctions cumulate to pathological conditions. Chronic, regular exposures result in health hazards. Those metals enter their body through several routes (inhalation, food contamination etc.,) and accumulate in the tissues and induce generation of reactive oxygen species (ROS) leading to oxidative damages. Workers in different industries are regularly exposed to heavy metals. Natural biologic scavengers such as algae, azolla and other aquatic plants possess the ability to uptake mercury traces from the environment. succimer) and dimercaptopropanesulfoxid acid (DMPS) are currently used as chelating agents in mercury poisoning. Besides supportive therapy, British anti lewisite, dimercaprol (BAL), 2,3-dimercaptosuccinic acid (DMSA. Silver nanoparticles are used as a sensitive detector of low concentration Hg 2+ ions in homogeneous aqueous solutions. ![]() Gold nanoparticles (AuNPs) are a rapid, cheap and sensitive method for detection of thymine bound mercuric ions. methyl mercury) can be detected easily in feces. Urinary concentration is a good indicator of poisoning of elemental and inorganic mercury, but organic mercury (e.g. Mercury level can be measured in plasma, urine, feces and hair samples. water, food, soil and air lead to toxic effects on cardiovascular, pulmonary, urinary, gastrointestinal, neurological systems and skin. Long term exposure to mercury compounds from different sources e.g. Mercury compounds are classified in different chemical types such as elemental, inorganic and organic forms. Mercury poisoning cases have been reported in many parts of the world, resulting in many deaths every year.
