Assessment of aerosol emission sources in a traffic site combining on-line and ...
Coutinho, J. T.; Canha, Nuno; Galinha, C.; Martins, V.; Faria, Tiago; Almeida-Silva, Marina; Lage, J.; Rigler, M.; Mocnik, G.; Diapouli, E.In urban areas, evidence from epidemiological and experimental studies show that traffic-related air pollution has adverse effects on respiratory and cardiovascular systems. Urban air pollution accounts for 3% of mortality from cardiopulmonary disease and 1% of mortality from acute respiratory infections in children under 5 years, worldwide. Therefore, disease and mortality associated with vehicle emissions rep...
Neutron activation analysis of wheat samples
Galinha, C.; Anawar, H. M.; Freitas, Maria do Carmo; Pacheco, A. M.; Almeida-Silva, Marina; Coutinho, J.; Maçãs, B.; Almeida, A. S.The deficiency of essential micronutrients and excess of toxic metals in cereals, an important food items for human nutrition, can cause public health risk. Therefore, before their consumption and adoption of soil supplementation, concentrations of essential micronutrients and metals in cereals should be monitored.

Trace elements in wild and orchard honeys
Almeida-Silva, Marina; Canha, Nuno; Galinha, C.; Dung, H. M.; Freitas, Maria do Carmo; Sitoe, T.The present study aims the identification and quantification of trace elements in two types of honey samples: Orchard honey and Wild honey from mainland Portugal. Chemical elements content was assessed by Instrumental Neutron Activation Analysis (INAA). Concentrations were determinated for Ag, As, Br, Ca, Cl, Cs, Cu, Fe, K, La, Mg, Mn, Na, Rb, Sb, Sc, U, V and Zn. The nutritional values of both honey types were...
Indoor school environment: easy and low cost to assess inorganic pollutants
Canha, Nuno; Freitas, Maria do Carmo; Almeida, Susana Marta; Almeida-Silva, Marina; Ribeiro, Marcos; Galinha, C.; Wolterbeek, H. Th.Total particulate matter (TPM) was passively collected inside two classrooms of each of five elementary schools in Lisbon, Portugal. TPM was collected in polycarbonate filters with a 47 mm diameter, placed inside of uncovered plastic petri dishes. The sampling period was from 19 May to 22 June 2009 (35 days exposure) and the collected TPM masses varied between 0.2 mg and 0.8 mg. The major elements were Ca, Fe, ...
