Direct atomic absorption mercury determination in tissues and biological samples
INTRODUCTION Mercury and its compounds are highly toxic substances fo r humans. It occurs naturally and exists in various forms: elemental (or metallic); inorganic (e.g. mercuric chloride); and organic (e.g., methyl- and ethylmercury). These forms all have different toxicities and implications for health. Among naturally occurring mercury compounds, methylme rcury exerts a significant influence (neurotoxic action) on human ...
