- Assessing and managing sediment contamination in transitional watersPublication . Chapman, P. M.; Wang, F.; Caeiro, SandraSediment contamination remains a global problem, particularly in transitional waters such as estuaries and coastal lagoons, which are the recipients of chemicals from multiple near- and far-field sources. Although transitional waters are highly productive ecosystems, approaches for assessing and managing their sediment contamination are not as well developed as in marine and fresh waters. Further, although transitional waters remain defined by their variable and unique natural water quality characteristics, particularly salinity, the biota inhabiting such ecosystems, once thought to be defined by Remane's “paradox of brackish water”, are being redefined. The purpose of the present paper is to build on an earlier but now dated (>12 years old) review of methods to assess sediment contamination in estuaries, extending this to all transitional waters, including information on integrative assessments and onmanagement decision-making. The following are specifically discussed: chemical assessments; bioindicators; biomarkers; and, biological surveys. Assessment and management of sediment contamination in transitional waters need to be focused on ecosystem services and, where appropriate and possible, be proactive rather than reactive when uncertainty has been suitably reduced.
- Como realizar uma análise da situação alimentar e nutricional: determinantes do consumoPublication . Carapeto, CristinaO acto de nos alimentarmos desenrola-se de acordo com as regras impostas pela sociedade, o que influencia a nossa escolha alimentar. Essas regras são representadas pelas maneiras de preparar os alimentos, pela forma de apresentar os pratos e pelos rituais das refeições (como, por exemplo, os modos e as posições das pessoas à mesa, a divisão da comida entre os indivíduos, os horários estipulados, entre outros). Tudo isto contribui para que a pessoa se identifique com o alimento e também com a sua representação simbólica. Nessa relação, pode-se destacar a questão do ser humano como um ser vivo omnívoro, representado pela capacidade de comer de tudo, o que lhe dá uma suposta liberdade de escolha alimentar. Todavia, nem tudo é escolhido por ele, uma vez que o indivíduo é determinado por diversos factores, que irão pesar na decisão da escolha dos alimentos. Esses fatores podem englobar o ambiente, o qual está relacionado com os recursos disponíveis, com as relações sociais, assim como com a história individual.

- Epidemiological risk perceptions of people living close to open dumps in Nampula, Mozambique: a case study controlPublication . Tocoloa, Alexandre; Martinho, Ana Paula; Fernandes, Ana PaulaWhile the municipal solid waste management systems (MSW) dominated by the informal sector makes positive contributions to the environment, they are also characterised by inadequate service delivery, low waste recovery, operational inefficiencies and inadequate waste disposal. The presence, of municipal solid waste poses a threat to public health and the environment if not managed properly. Tocoloa, Martinho and Vaz-Fernandes focus on the detrimental impact of the MSW in Nampula city, in Mozambique, where populations live near open dumps with open burning. There chapter aims to analyze the perceptions about the effects on health and on the environment of these populations that live close to MSW dumps in the city of Nampula. Employing an epidemiological questionnaire to individuals residing in four different geographical areas, they find that the exposed populations may suffer some illnesses and injuries from living closer to the MSW but showed lack of awareness about it. The fact that waste collection is undifferentiated and the different types of MSW are all placed in these locations, it is expected that in addition to contamination by different vectors (mosquitoes, rats and domestic animals) that can cause different tropical diseases in these populations, other contaminants such as heavy metals and persistent organic compounds cannot be excluded. As uncontrolled waste burning is reported, these populations may also be exposed to dioxins and furans. These results point to the issues related to environmental justice and unequal exposure to the environmentally detrimental impact of a MSW dominated by the informal sector.

- Perceptions of populations and technicians in waste management in Nampula, MozambiquePublication . Tocoloa, Alexandre; Martinho, Ana Paula; Fernandes, Ana PaulaUrban solid waste management systems (MSW) in developing countries are characterized by inadequate service delivery, low waste recovery, operational inefficiencies and inadequate waste disposal. The presence of urban solid waste poses a threat to public health and the environment if not managed properly. In Nampula city, in Mozambique, peri-urban popula-tions live near open dumps with open burning. The present study aims to analyze the implica-tions and perceptions about the effects on health and on the environment of these populations that lives close to MSW dumps in the city of Nampula. A mixed survey was used with data col-lection instruments: an epidemiological questionnaire and interview guides. The common ques-tions of these two tolls were analyzed and compare the perception of the population with the perception of health and environmental technicians of the municipality of Nampula.
