Heavy metals in our environment
In the analysis of toxic metals in the body, in which organ(s) do you find the highest accumulation of metals like lead, arsenic, mercury and cadmium. What are the permitted environmental levels of these metals. Is it possible to find large amounts of arsenic in the kidney and still have no manifestation(s) of any acute or chronic toxicity ? Please do reply.... thanksANG Nnamdi

This is not a medical site. If there is actual or probable human exposure to any of these toxic metals, contact a medical doctor or government health agency ASAP. Information on target organs, exposure limits, acute and chronic exposure symptoms is given in the Material Safety Data Sheet (MSDS) for each metal (or any compound of the metal). In the U.S., these are furnished by the chemical supplier by law; if not so in your country, download MSDSs from U.S. chemical & laboratory supply company websites, e.g., Fisher Scientific (https://www1.fishersci.com/index.jsp), Spectrum Chemicals (http://www.spectrumchemical.com/retail/), etc.Ken Vlach [deceased]

Pollution in Nigeria water effect, toxicity,c auses and solutionKabir

Kabir, pollution in Nigeria and elsewhere results from poor choices based on lack of knowledge, lack of alertness, laziness and/or selfishness. Part of it results because we wait for others to do what we should do ourselves.
The pollution and terrible poverty in a state where such huge petroleum resources are being exploited, is a huge and shameful scandal. But do your own homework so you can be a part of the eventual solution.
