Institutul de Geologie
şi Seismologie al AŞM

Laborator de Geochimie

 Directiile Stiintifice - Geochimia elementelor si compusilor toxici in mediul ambiant, studiul calitatii apelor freatice si minerale.

Scopul Cercetarilor - studiul proceselor de migrare, acumulare si transformare ale metalelor grele, pesticidelor, policlorbifenilelor (PCB), hidrocarburilor poliaromatice (PAH) si a altor poluanti organici in obiectele mediului ambiant: ape naturale si reziduale, soluri, sedimentari contemporane, roci, plante si produse agricole.

Importanta Practica a cercetarilor stiintifice - Elaborarea recomandarilor in privinta diminuarii impactului poluarii cu elemente si compusi toxici, asupra calitatii mediului, produselor agricole si sanatatii populatiei.

Laboratorul este acreditat de catre organul de Acreditare si Atestare a
Republicii Moldova
(Certificat SNC MD CN00 41 0184)

Laboratorul efectueaza calitativ si la pret redus urmatoarele lucrari analitice:

Determinarea calitatii apelor minerale si potabile prin metode standard.
Analiza compusilor organici (pesticide, PCB, PAH) in diferite obiecte ale mediului ambiant: ape naturale, ape reziduale, soluri, sedimentari contemporane, plante, produse agricole si produse alimentare.
Identificarea substantelor si impuritatilor in diferite obiecte, prin cromatografie de gaze cu detector de masa.
Determinarea elementelor chimice toxice (As, Se, Hg, Pb, Cd, Cu, Zn, Ni, Cr, Al, Mn, Fe) in diferite obiecte: ape naturale si tehnologice; produse alimentare; produse agricole; soluri; depuneri din ape reziduale; metale si aliaje.

Echipamente si metode de cercetare
