1. RESÍDUOS DE BIFENILOS POLICLORADOS EM ARROZ E FEIJÃO DO ESTADO DO RIO GRANDE DO SUL / RESIDUES OF POLYCHLORINATED BIPHENYL IN RICE AND BEANS IN THE STATE OF RIO GRANDE DO SUL
Polychlorinated biphenyls (PCBs) were commercially produced between 1929 and the mid 1980s with industrial purposes. The same properties that interested industrially, as chemical inertness, high dielectric constant, resistance to burning; were also responsible for the spreading of the PCBs in all of the environmental compartments, mainly due to the inadequat

2. DETERMINATION OF POLYCHLORINATED BIPHENYLS IN POWDERED MILK AND ESTIMATED DAILY INGESTION IN PRE-SCHOLARS / DETERMINAÇÃO DE BIFENILOS POLICLORADOS EM LEITE EM PÓ E INGESTÃO DIÁRIA ESTIMADA POR PRÉ-ESCOLARES
The polychlorinated biphenyls are synthetic organoclorated substances that can produce noxious effects to health. There are not any natural sources of PCBs known in the environment. They can be liquid or solid, colorless or clear yellow. Some of them are volatile and may remain as steams in the air. They were widely used in the industry as oils for transform

3. Maternal consumption of polyphenol rich foods in late pregnancy and fetal ductus arteriosus flow dynamics
Objective: To test the hypothesis that maternal consumption of polyphenol-rich foods during third trimester interferes with fetal ductal dynamics by inhibition of prostaglandin synthesis. Study Design: In a prospective analysis, Doppler ductal velocities and right-to-left ventricular dimensions ratio of 102 fetuses exposed to polyphenol-rich foods (daily est

4. Evaluation of the nitrate text in folhosas hortaliças produced by different systems of culture. / Avaliação do teor de nitrato em hortaliças folhosas produzidas por diferentes sistemas de cultivo.
Nitrate is naturally present in vegetables as a nitrogen source for their growth, the amount depending on genetic factors, the availability of this nutrient for the plant and environmental factors. It has been estimated that more than 70% of the nitrate ingested daily by man is supplied by vegetables. The present work evaluated the nitrate content in leafy v
