O envenenamento por arsénico é uma condição médica causada por níveis elevados de arsénico no organismo. A principal causa do envenenamento por arsénico é a água subterrânea que contém naturalmente elevadas concentrações de arsénico. Os sintomas do envenenamento por arsénico começam com dores de cabeça, confusão, diarreia grave e sonolência. À medida que o envenenamento evolui, podem ocorrer convulsões e alterações na pigmentação das unhas, denominadas leuconiquia estriada. Também se observam as linhas de Aldrich Mee (leucoparoníquia) nas unhas. Quando o envenenamento se torna agudo, os sintomas podem incluir diarreia, vómitos, sangue na urina, cãibras musculares, queda de cabelo, dores de estômago e mais convulsões. Os órgãos do corpo que são normalmente afetados pelo envenenamento por arsénico são os pulmões, a pele, os rins e o fígado. O desfecho final do envenenamento por arsénico é o coma e a morte. O arsénico está associado a doenças cardíacas (doenças cardiovasculares relacionadas com a hipertensão), cancro, acidente vascular cerebral (doenças cerebrovasculares), doenças crónicas das vias respiratórias inferiores e diabetes. O arsénico pode ser medido no sangue ou na urina para monitorizar a exposição ambiental ou profissional excessiva, confirmar um diagnóstico de envenenamento em vítimas hospitalizadas ou para auxiliar na investigação forense.
