TITLE:

INFLUENCE OF AQUATIC HUMIC SUBSTANCES FOR THE BIOAVAILABILITY OF POINTS TOXIC METALS IN SURURU (MYTELLA FALCATA) PRESENT IN THE LAGUNAR MUNDAÚ - MANGUABA ESTUARINE COMPLEX

KEY WORDS:

Substâncias húmicas aquáticas; Complexação; Metais tóxicos; Sururu

SUMMARY:

The Mundaú-Manguaba lagoon estuary complex is considered the most important ecosystem for the state of Alagoas. This region stands out for several factors, such as: extension of its lagoons, proximity to the state capital (Maceió), number of people involved in fishing activities, environmental and social problems and their productivity. Estuaries are the most fertile regions in the world, given their productivity, several species of organisms develop in these ecosystems, such as the bivalve mollusk of the Mytilidade family, popularly known as Sururu. Bivalve molluscs are biological samplers and bioaccumulators of matter or substances existing in the water and its ingestion may represent a potential risk for those who eat it due to the possibility of heavy metals in the capture waters. Some metals, such as mercury, lead and cadmium, have no function within organisms and their accumulation can cause serious diseases, especially in mammals. Contamination by lead and cadmium can cause health-related disorders, including problems with the kidneys, livers, vascular system, increased blood pressure and metabolic disorders. SHAs influence the toxicity of some metals, forming complexes with different relative abilities, which may or may not reduce the bioavailability of contaminants for aquatic organisms and soils. According to what was exposed, the objective of this work is to evaluate the interaction between SHA and potentially toxic metals in the absence and presence of the bivalve mollusk sururu (Mytella falcata) disposed in the Mundaú-Manguaba lagoon complex.
