  • Canada: Toxic lead exposure via an unusual source: New BC reporting regulations may prevent similar cases



    Exposure to lead in Canada has fallen dramatically with its removal from paint, gasoline, plumbing, and other consumer and industrial products. Nevertheless, lead toxicity still occurs. A 64-year-old male was seen in emergency rooms throughout the Lower Mainland over the course of 5 months, complaining of abdominal pain, dizziness, weight loss, and nausea. Intensive workup for

    Toxic lead exposure via an unusual source: New BC reporting regulations may prevent similar cases

    Issue: BCMJ, vol. 61 , No. 1 , January February 2019 , Pages 41 BCCDC By: David McVea, MD James Lu, MD Morris Pudek, PhD Benjamin Sehmer, MD Tom Kosatsky, MD

    The patient had been taking an ayruvedic herbal remedy purchased in India to treat his type 2 diabetes. A laboratory analysis determined that each tablet contained approximately 12.5 mg of lead. The patient had been taking two tablets daily for many years, yielding a sustained daily exposure of 25 mg.
    ..
    As part of new regulations under the BC Public Health Act, as of 1 January 2019, laboratories testing BC patients and paid for by public insurance are obliged to report all analyses of lead and mercury in blood and urine to the BC Provincial Health Officer, who has delegated the receipt, investigation, and surveillance of results to the BC Centre for Disease Control (BCCDC) acting in concert with regional health authorities. BCCDC will assess trends in testing and in metal biomarker levels by geography and demography, and for those 100 or so results per year above an investigation/action threshold, will contact the ordering clinician and through the clinician the patient, to assess the likely source of exposure. ...

    These herbs might have been heavy metal accumulators grown in an area contaminated with mine tailings or industrial pollution.

    Heavy metals are among the most important sorts of contaminant in the environment. 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. Currently, phytoremediation is an effective and affordable technological solution used to extract or remove inactive metals and metal pollutants from contaminated soil and water. This technology is environmental friendly and potentially cost effective. This paper aims to compile some information about heavy metals of arsenic, lead, and mercury (As, Pb, and Hg) sources, effects and their treatment. It also reviews deeply about phytoremediation technology, including the heavy metal uptake mechanisms and several research studies associated about the topics. Additionally, it describes several sources and the effects of As, Pb, and Hg on the environment, the advantages of this kind of technology for reducing them, and also heavy metal uptake mechanisms in phytoremediation technology as well as the factors affecting the uptake mechanisms. Some recommended plants which are commonly used in phytoremediation and their capability to reduce the contaminant are also reported.
