Collected samples were sent to certified laboratories for analysis. Data were recorded from June to November 2014 in the seafood market "Las Mercedes" of Babahoyo city province of Los Ríos, Ecuador. Environmental impact matrix cause-effect was designed to determine the magnitude of impact to the environment. It was found that wastewater generated seafood market are higher than the provisions of the environmental standard BOD 1672.8mg/l (n=5) values, COD 2592mg/l (n=5) and Oils and Fats 798.02 mg/l (n=5). Fish samples collected showed high rates of chemical and microbiological contamination Aerobic Mesophilic 3,25E+5cfu/g (n=15) of E. Coli 1,34E+3cfu/g (n=15); presence of Salmonella sp. in 10 samples of fresh fish (n=15). Public health (-22) is the factor with the greatest negative involvement, with significant involvements on water quality (-19), the reception phase (-30) produced the greatest negative impacts to the environment, primarily on factors: physical and socio-culturally.
