Nervous system symptoms such as numbness, tingling of hands and feet, weakness. heavy metal ions as essential micronutrient, while the same at higher concentrations and even more ions such as Cd, Hg, as are strongly poisonous to the metabolic activities. Most heavy metals have a high atomic number, atomic weight and a specific gravity greater than 5.0 Heavy metals include some metalloids, transition metals, basic metals, lanthanides, and actinides.Although some metals meet certain criteria and not others, most would agree the elements mercury, bismuth, and lead are toxic metals with sufficiently high density. Hence, there is a need for proper understanding of mechanism involved, such as the concentrations and oxidation states, which make them harmful. However, at higher concentrations they can lead to poisoning. Some heavy metals have bio-importance as trace elements but the biotoxic effects of many of them in human biochemistry are of great concern. Heavy For example in Malaysia a particularly vexing problem is the presence of toxic and hazardous heavy metals in industrial effluents. Research was collected through PubMed, and it was compiled to … Heavy Metal Toxicity refers to an overexposure to lead, mercury, arsenic, cadmium, chromium or other high density or metallic element that causes irritation or damage to the body.

This technology is environmental friendly and potentially cost effective. Chelation therapy — Of all heavy metal detox products, chelation therapy is probably one of the most effective ways to reduce serious heavy metal exposure, especially metals like lead, mercury, aluminum and arsenic. These metals can also affect a baby’s brain development. They are found in elemental form and in a variety of other chemical compounds. Several methods already used to clean up the environment from these kinds of contaminants, but most of them are costly and difficult to get optimum results. %�쏢 ç0ªî]ˆ…€ÍÑsސÞgCü¦N&ràBӐّ)(0(5â¨õ9„!Ùü‹HäÑ^‡ìÀü(0ú^´ÉZzZtØZë©ú'¶Ö¾‘94l«B,÷ÐY3僌vyRIUŠ¤CRBX[»wÂO»ÓZôË]„ds›µ˜hŸjÚlÝ薺öC~©nr§èøhÁÔt邊 .ºôÜÜ1 Îõà¬2‡j¦á z”ŒÂ™ÈGÝɆˆtnÅ~Œ–°‡‘Â(ݨ²—Ð¥1Ó¿a–@O¥RpAYšCÿõåÄðZM]'¥WYôßZBZOåH;-;ŽqÌYw>Èc⏬QEa¨Ê¡1XJ†^qJô°I8š3Iï¹ÁÕÝZjI­Âµa¿è0?&(ÉÚ6-%,ÓµmZj¾ùúª6-u}_ÐÒÖ¸Ðå/î÷t÷Ô¸ME ÜÉ%œ¥é-´'E7–)ÄÃÔÀr@µOM…Œ»®-›¼‚7B­RTB†W"EŒ†r)åé©iBS^¤0{…ëe#ŽIpàXt úaք9„Þ;C.G͑iÂÀµ Q>[÷Š˜–{!v|]ç ²ù3Mÿ)Øx å™êclÛ>n’¿Ü`uð:~àÅJA¤“‘́põNkáA}Ajä=5µ=î(âê õ›”.Âg"ɍ9‰|Pޅ^§Ù³‚Ñ‘ŒMXë@Wd°jtÏ´-t§ÚL %€B=ºœä¾àƒíæ|°Îù`³ ¿©ËßT(;ôÏ;Wve¥ôW¤K"gJ4jB&”RöÒ햼—m©¾:ß+°I1ó`ˆº°îœRWãAÖÕ2íá~ç–û¤öjÖ¨î†Yç¾wÍ@i‰K©€‹ •”BK#ð°½ÔùGf%»Üìô?Cn†çµÅqû+L?«IñTn9ÆÈ`‡¼'ÍiÀJÔÿi$…%Ðp4ÖPîÞ:ÊÝ4’êÚÜ¢>¥h»úÐUŽ‘ZQ›¤Ó…°‚Ý¥v•»÷÷ {IZ“ÃÑ%À‹¥ºCb+sDB Zåt̏Tóz„ºãVRø‘Ošý>‘dðs©5áuy»5ìúVÃõEè4ÔÝàJÈÝ}èh_Oè`#àcÊG½¯ó›KlV‡G•NbGD‚o-jR¥Ã#OFÖ1Šn±™!ûôoðsS×g=VaC$ÜcLPI³¹–÷‰°Yô¡û(IÍ©…%½Çú¬€ƒE§ #ž.
