There are more cruises on the Douro but not all of them treat water

Guardianship guarantees its own residual station on Portuguese hotel ships, but not on foreign ones. Captaincy issued five notices. Waste collected by tanker trucks is dumped into the sewer system.

In the first half of this year alone, there were 11,322 trips on the Douro River, including hotel ships, day cruises or pleasure boats. There are 132 more than registered last year. And, although the Ministry of Economy and the Sea guarantees, to JN, that “hotel ships flying the Portuguese flag all have their own wastewater or sewage treatment system”, the same cannot be said about foreign cruises operating in the Douro.

Pollution levels of the Ave River above those recommended by the EU

ICBAS researchers warn of the impact of pollution caused by farming in the Ave river basin.

A study of the Instituto de Ciências Biomédicas Abel Salazar of the University of Porto (ICBAS-UP), part of the ATLANTIDA Project (financed by the European Regional Development Fund (ERDF) through the NORTE 2020 Program), and recently published in the journal Marine Pollution Bulletin, demonstrated that the use of pesticides from agricultural practices still has a significant negative impact on the Ave river.

What was, about 30 years ago, one of the most polluted rivers in the country and in Europe, the result of discharges from the textile industry characteristic of that region, continues today to face problems related to the pollution caused by the agricultural exploitation located in its hydrographic basin.

For Maria João Rocha, responsible for the study, these results are very relevant, in the sense that pollution in the Ave River is associated with the presence of industries, often forgetting that the effluents also come from agricultural areas.

How warmer sea water will affect our health and food

In Santos Populares, there were those who noticed that the fish were not that big. It is a direct effect of rising sea temperatures, but the consequences do not stop there.

Diseases, new animal species and more storms. Sea water is warming from year to year and this will have consequences in many ways, affecting our well-being, but also health and safety.

The increase in water temperature is causing an effect that is still unknown, but that scientists have already begun to identify, lacking to understand the dimension. Adriano Bordalo e Sá, Professor at the 'Instituto de Ciências Biomédicas Abel Salazar' (ICBAS), warns that the absence of regular screenings may be hiding a problem in Portuguese waters.
