MATiSSe - Microplastics on AgriculTural SoilS: assessment of their impact on physical, chemical and biological soil properties
AGRICULTURAL SOILS
MICROBIAL ASSESSMENT
MICROPLASTIC
NEW CONTAMINANTS
SOIL
RISK ASSESSMENT.
This project proposes to study the impact of Microplastics in agricultural soils, though the assessment of several soil properties: physical (soil texture, soil structure and bulk density), chemical (pH, cation exchange capacity, organic matter, potentially toxic elements and compounds) and biological properties (soil enzymatic activity and/or soil organisms). Although this project could be developed in any region, Estarreja region offers an exceptional environment due to having a mixed area of agricultural and industrial activities, where MPs can act as carriers of potentially toxic elements and compounds, as reported for aquatic ecosystems. Further, insights brought by this project can be useful to support the development of soil management measures specifically targeting the restoration of the quality of soils from Estarreja.

MICROCLIM - Effects of global warming on microbial populations from contaminated agricultural soils in the area of Estarreja
Climate change
Air temperature
Soil moisture
Soil microbiota
Multiple stressors
Anthropogenic-degraded ecosystems
The Intergovernmental Panel on Climate Change (IPCC) predicts increasing air temperatures and decreasing soil moisture content, the soils being among the most affected components of terrestrial ecosystems, especially in anthropogenic-contaminated areas. Soil microorganisms are key players in terrestrial ecosystem functions and services, quickly responding to environmental stresses. MICROCLIM aims to assess how microbial populations of agricultural soils affected by the contamination derived from the Estarreja Chemical Complex may be affected under the current global warming perspective, by using changes at structural and functional level. The specific objectives are: 1) assessing structural and functional changes in microbial populations of contaminated agricultural soils induced by single climate factors (soil moisture content and air temperature and their relation to changes in soil chemical and physicochemical parameters, and 2) assessing structural and functional changes in microbial populations of contaminated agricultural soils under different climate change scenarios, simulated by climate factors combinations (soil moisture content and air temperature), and their relation to changes in soil chemical and physicochemical parameters. Climate factors ranges will be established based on the emission scenarios predicted by the IPCC by 2100. The project will rely on changes in soil microbial populations at structural (bacterial community phylogenetic composition) and functional (microbial metabolic activity) level and their relation to key soil parameters (pH, organic matter, metal(loi) availability). MICROCLIM will improve the capacity to predict the consequences of global warming in soil microbiota from anthropogenic-contaminated soils, which, in turn, will enable a better preservation and sustainability of soil ecosystem functions and services.

PRISMA - Pulmonary Rehabilitation: a response for patients with COPD in an InduStrialized environment and its implication on lung MicrobiotA
COPD
PULMONARY REHABILITATION
LUNG MICROBIOTA
PRISMA capitalizes on MicroRESPIRA, which found high abundance of bacteria, allergic and pathogenic agents for the human respiratory tract above the admissible values set by the National Legislation in the homes of patients with chronic obstructive pulmonary disease. Therefore, these people are at higher risk of having acute exacerbations, which causes severe individual, social and economic impacts. However, little has been done to improve patients’ awareness about the impact their home environment might have in their disease and quality of life. Pulmonary rehabilitation (PR) is an evidence-based intervention known to improve patients’ education, reduce symptoms, exacerbations, hospital admissions and quality of life however, it is highly inaccessible. PRISMA will overcome this barrier. It will also enhance our understanding of the mechanisms behind the effectiveness of PR by exploring the modulation of lung microbiota, since acute exacerbations might be caused by individual’s microbiota, however, this is still poorly understood.

Publishing of the Book «A Fábrica e a Vida – Narrativas e Imagens dos trabalhadores do Complexo Químico de Estarreja em torno do trabalho nas fábricas, da sua complementaridade com outras atividades e do risco ambiental» (The Factory and the Life – Narrat
Content Analysis
Environmental Risk from Industral activities
Industry work
In 2015 we proposed a project to OHMI – Estarreja titled A Fábrica e a Vida – Narrativas e Imagens dos trabalhadores do Complexo Químico de Estarreja em torno do trabalho nas fábricas, da sua complementaridade com outras atividades e do risco ambiental», within which 30 in-depth interviews or life stories to current and former workers of the Estarreja Chemical Complex (CQE) were registered. Those life stories constitute a rich patrimony, not only to CQE itself, but also to Estarreja Municipality, as they convey the workers’ narratives about their life trajectories, about the nature of work in the factories, about environmental and health risk perceptions, as well as about the complementary activities.
The evidence gathered from these Life Stories also helps to understand the population adaptation strategies regarding the territorial transformations (economic, environmental, demographic and social) induced by the creation and functioning of CQE. Therefore, through the narratives gathered, it is possible to rebuild the collective history and memory of Estarreja population and territory in their relationship with the CQE which, since 1952, constitutes a strong and relevant identity feature both for the territory and the population.
The analysis of the interviews reveals extremely interesting aspects about the transformations of CQE, work and life during the last four or five decades, which are worthwhile to be disclosed to a wider public, in order to preserve this rich and important cultural patrimony and to disseminate the memories on the ‘factory and the life’. The disclosure and dissemination of those narratives is also a way of paying tribute to the main protagonists of the relationship between the factories, the territory and the daily life: the workers of CQE.

SOILRICE - Geochemical and ecological soil quality status in cultivated and abandoned rice paddies
Rice paddies
Soil quality status
Agrochemicals
Heavy metals
Salinity
Ecotoxicological essays
Diatoms
Estarreja is a region of marked contrasts, where an almost unique ecological reservoir, the Baixo Vouga Lagunar (BVL), contrasts with one of the most important chemical industry of the country. Fortunately, these contrasts between nature and man’s hand are not always so marked. Integrated in this ecological reserve, man modelled the land and used the surface water reservoirs to develop there an agricultural practice dedicated to rice cultivation, and perfectly harmonized with the surrounding landscape – the “Bocage landscape”.
However, rice cultivation in the region of BVL (the only place in the north of Portugal where rice is cultivated) has been abandoned in the last decades. The reasons for this abandon are several, however the main one is the low paid prices for the produced rice and the unproductivity of the soils caused by saline water intrusion.
Since now some funds are being provided to encourage rice production in this region, it is important to study the actual quality status of the soil (geochemical and ecological status) in the rice paddies under cultivation and in the abandoned ones. This study is crucial not only to assess and understand the potential of this area to support this agricultural practice (in the present and in the future), but also to estimate the possible environmental impacts that may arise from rice cultivation in a protected ecological landscape like this one.

Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality worldwide, particularly in low and middle-income countries. Historically, smoking has been identified as the leading cause of chronic obstructive pulmonary disease (COPD) in the world. However, exposure to other risk factors is increasingly being recognized as a possible cause of COPD. Indoor air pollution, for example, is one of those risk factors. The sources of indoor contamination might be derived from industrial activities and/or indoor activities such as biomass burning for cooking and heating.
About 3 billion people, half the worldwide population, are exposed to smoke from biomass fuel compared with 1.01 billion people who smoke tobacco, which suggests that exposure to biomass smoke might be the biggest risk factor for COPD globally. In populations with low smoking prevalence, such as women in developing countries, it is estimated that 80% of chronic bronchial obstruction cases are attributable to factors other than tobacco.
In this project, we intend to implement the RESPIRA project that is being developed in the highly industrialized area of Estarreja, Portugal, in Tessekéré, Senegal in order to study the contribution of exposure to biomass smoke to chronic pulmonary diseases. The results obtained with these twin projects will allow to better understand the role of the indoor environment on the development and progression of chronic obstructive pulmonary diseases in two countries with distinctive contamination sources and with different socio/economic and geographical characteristics

Environmental quality
Soil, an important environmental compartment, is largely affected daily by anthropogenic activities such as industries, traffic and waste disposal. These activities can bring to the soils large quantities of several contaminants and consequently they can easily enter the food chain and the trophic scale of ecosystems via plants and animals.
This type of organic pollutants can persist for long times in the environment, being susceptible to transport for long distances, then they can easily reach a large geographic area and be widely dispersed.
It is of an extreme importance to assess the environmental and human health risk pose by this problem. In this work, an evaluation and a comparison study will be done through bioavailability tests and ecotoxicological bioassays with plants and invertebrates in order to assess the real risk inherent to the presence of such pollutants in soils of an important industrial area: Estarreja (Portugal).

C-GRASS – Seagrass meadows: Blue carbon spatio-temporal changes at Murtosa region (Ria de Aveiro)
“Moliço”
Zostera noltei
carbon stocks
stability
temporal changes
sedimentation
climate regulation
Seagrass meadows are globally significant blue carbon (C) sinks contributing to climate regulation, reduce sediment erosion and increase the sediment stability; thus, playing a key role in many ecosystem functions and ecological processes. Nevertheless, seagrass loss and degradation is occurring worldwide, leading to the release of C stored over millennia at these ecosystems. In Ria de Aveiro, seagrass meadows followed the global trend, and there was a great loss along the last decades of 20th century, mainly due to hydrological changes and dredging activities in the lagoon. Subtidal seagrass meadows disappeared and there was a great reduction of intertidal meadows extension and biodiversity. The harvesting of “moliço” (a mixture of seagrasses and macroalgae) and its use as fertilizer in agriculture was a traditional activity at Ria de Aveiro until the 1960’s. “Moliço” was collected and transported using traditional boats (“moliceiro”) and was frequently unloaded and commercialized at Murtosa wharfs. However, the economic value of this activity decreased over the 20th century and is currently lost. In the context of the OHM-Estarreja research topics “Biodiversity Evolution – ‘Evaluation of changes at Ria de Aveiro ecosystems’ and ‘Interaction among species, communities, population and ecosystems’”, this proposal intends to evaluate the spatio-temporal changes in Zostera noltei meadows at Murtosa region and the impacts of its vulnerability on the blue C stock. Potential drivers of change in these meadows will also be addressed.

DIGSOIL - Digital geochemical soil mapping in the areas of Estarreja, Vicdessos, Gardanne and Marseille: georeferenced stacking layers of geochemical mapping integrating environmental, urban planning, ecological and health data
Geographical Information Systems
Potentially Toxic Elements
Geostatistics
Multivariate Analysis
Isotope Fingerprinting
The main aim of the project is to carry out a systematic geochemical soil mapping in the areas of Estarreja, Vicdessos, Gardanne and Marseille. Geochemical soil mapping is needed in order to understand the sources, transport, transformations, and fate (including human and ecosystem health) of chemical constituents in the settings of the different Observatoires Hommes-Milieux (OHMs). Geochemical soil maps will be produced by the regional interpolation of element concentration data obtained from samples collected from georeferenced sites and the digital soil maps (DSM) will be made publicly available on the Internet to potential end-users. Elemental concentrations in the soil will be determined using a field-portable X-ray fluorescence spectrometer (FPXRF). Given the multiplicity of anthropogenic sources that are characteristic of urban and industrial environments under study, isotopic studies will be carried out for tracing and quantifying mixed sources of certain potentially toxic elements (PTEs) in soils.

DRuMBEAT - Dirt-based microorganisms towards soil bioremediation of multiple contaminants
Bioremediation
Multiple contaminants
Biochar
Mixed microbial cultures
While soils of Estarreja continue to be important sinks of persistent contaminants, existing remediation techniques are often ineffective and fail when addressing multiple contaminants. Biochar – biomass pyrolysed for enhancing carbon sequestration and other biomass productivity – presents a dual potential for improving soil decontamination: its exceptionally high porosity can both promote adsorption of contaminants and provide habitat conditions for microbial biofilm development. It is hypothesized that the microbiomes existing in contaminated soils present enhanced abilities to thrive under such adverse environments, thus allowing for a natural improvement of the ecosystem services provided by the soil. The proposed research aims at a novel technique for remediating soil contamination, through development of biochar-attached biofilms made of mixed microbial cultures taken from those “dirty” soils identified in Estarreja and stimulated to oxidize both organic and inorganic contaminants. The work programme encompasses: microbial fingerprinting of the contaminated soils, ex situ development of biofilms cultivated from those microbiomes onto biochar carriers and assessment of the contaminant uptake kinetics.
