“…The Goiana River estuary is under numerous human interferences. Like many other tropical estuaries, it is highly impacted by sugarcane plantations (Brockmeyer and Spitzy, 2011;Thorburn et al, 2011;Davis et al, 2013;de Melo Gurgel et al, 2016;Valera et al, 2016).…”

“…Tropical soils present low levels of organic matter, causing difficulties for their maintenance for the cultivation of sugarcane. Large quantities of fertilizers which are carried toward the estuarine channel by the rainfall is necessary for the yield of crops (Alexakis, 2011;Brockmeyer and Spitzy, 2011;Humbert, 2013), causing the consumption of the available dissolved oxygen in the water. The projected trend of change influenced by anthropogenic actions in global climate includes several events: water heating (change in chemical kinetics of reactions in the estuary, stratification of the water column, hypoxia); rising sea levels; reduction of water pH (acidification); loss/replacement of habitats (species migration, invasion of exotic species) and the expansion of the tropics (Attrill and Power, 2000;Mudge et al, 2007;Zhang et al, 2010;Statham, 2012;Madsen et al, 2014).…”

“…Water quality loss in estuaries are, therefore, one of the worst forms of water pollution (Karydis and Kitsiou, 2013). The main causes of decline in quality of the estuarine aquatic bodies are related to water subtraction and releases of agricultural, domestic and industrial effluents (Alexakis, 2011;Brockmeyer and Spitzy, 2011), altering the physical, chemical and biological properties of water (Kitsiou and Karydis, 2011;Karydis and Kitsiou, 2013), and consequently dropping the concentrations of dissolved oxygen (Yin et al, 2004;Mudge et al, 2007;Breitburg et al, 2009).…”

Anthropic processes degrade quality of estuarine environments, resulting in a worrying form of water pollution. The objective of the study was to describe and discuss interannual and seasonal changes of water quality based on indicators monitored in Goiana River estuary, as well as identifying the main drivers of such changes. We considered three estuarine areas or habitats (upper estuary, middle estuary and lower estuary), and two seasons (dry and rainy) for anchoring sample design. The information collected for surface and bottom water include water temperature (• C), salinity, dissolved oxygen (mg L −1), saturation (%) and Secchi depth (cm) (n = 864). The monthly total rainfall (mm) was compiled from public database. Multivariate analyses highlight inter dependency among these parameters. Water quality was reduced in dry periods (including episodes of hypoxia), but generally increased toward the mouth of estuary. Rainfall is the most important factor in the renewal and maintenance waters of small tropical estuaries. Regions most sensitive to climate change where water resources are depleted and/or compromised should pay even more attention to upcoming changes in rainfall (seasonal) and climatic patterns in addition to better water management practices.

The WPI is an important tool to summarize a large number of water quality data into simple terms which is one of the most effective ways to interrelate information on water quality trends. The information generated can help to guide policy makers on effective restoration, conservation and management of water resources. In this technique the weightage for various water quality parameters is assigned to be inversely proportional to the recommended standards for the corresponding parameters. Estuaries represent productive aquatic habitats and are characterized by dynamic biogeochemical processes. Water quality loss in estuaries is, therefore, one of the worst forms of water pollution. For the analysis of water parameters, the water samples were collected and preserved in pre-rinsed plastic bottles at monthly intervals during June 2011–May 2013 for the period of two years from the Dumas vicinity of Tapi estuary. Temperature and pH were analyzed in situ and other parameters were analyzed as per standard references. The WPI in the studied area in the first year ranged between 1.2334 to 7.8266 whereas it varied from 1.797 to 6.439 in second year of the study. The higher value of WPI was observed during the month of December and January in the first year and in the month of December in the second year indicating high polluted nature of the estuary. The overall study revealed the polluted nature of the water ranging from mild to severe during different months in the studied area. It was observed that estuarine environment was polluted by the impact of anthropogenic as well as industrial activities. This study is important as understanding the ecological status of the estuarine habitats is imperative for successful environmental management and sustainable development.

“…A perda de qualidade das águas nos estuários é, em regra geral, é uma forma de poluição da água (KARYDIS; KITSIOU, 2013). As causas do declínio da qualidade das águas estuarinas podem estar relacionadas a liberações de água agrícola (resíduos de água utilizada em irrigações), efluentes domésticos e industriais (ALEXAKIS, 2011;BROCKMEYER;SPITZY, 2011), alterando as propriedades físico-químicas e biológicas de água (KITSIOU; KARYDIS, 2011; KARYDIS; KITSIOU, 2013), e consequentemente, diminuindo as concentrações de oxigênio dissolvido (BREITBURG et al, 2009).…”

O Complexo Portuário de Vila do Conde está situado nas imediações do rio Pará. Este trecho é caracterizado por morfologia rebaixada e planícies arenosas curtas. O clima é tropical chuvoso de tipo Afi, com chuvas (média mensal de 336 mm), ventos do NE (média diária de 1,06 m/s-1), a meso-maré atinge 3,4 m de altura e correntes de até 1,8 m/s. Este artigo objetiva avaliar a qualidade das águas estuarinas do rio Pará (Vila do Conde), utilizando IQA, parâmetros físicos e químicos. Realizou-se 5 campanhas de amostragem, duas no período chuvoso, uma no período de transição e duas no período seco, em 7 estações (nas imediações do Porto), nos instantes de vazante e enchente. Os procedimentos foram realizados de acordo com os métodos delineados no Guia nacional de coleta e preservação de amostras, SMEWW e US EPA. As variáveis permitiram inferir que, em média, as águas estuarinas apresentam melhores valores de IQA na maré vazante (PVCAS01VAZ = 37, PVCAS02VAZ = 39, PVCAS03VAZ = 41, PVCAS04VAZ = 39. PVCAS05VAZ = 40, PVCAS06VAZ = 39, PVCAS07VAZ = 40). Ratificando esta tendência, mensurou-se (média) menores e maiores concentrações de CTT (71 a 1559 NMP/100 mL-1) e OD (7,35 a 7,59 mg/L-1), respectivamente, na maré vazante.
