“…Population density and urbanization are unevenly distributed in the watershed, concentrating on the sub-watersheds of the southern region and part of the northern region. In contrast, the sub-watersheds of the western region are less urbanized and densely wooded (Silva, 2016).…”

“…In our study, all tributaries classi ed as "Non-urbanized" are located in the West region of the watershed: a densely forested area with no/ or few constructions and with highly sloping relief (Silva, 2016). The high slope in relation to the receiving lagoon body excludes the possibility that the microplastics detected in these water bodies come from a direct in uence of the lagoon water at the sampled points.…”

“…The CLW has presented an intense and disorderly urbanization process (Silva, 2016). From 2001 to 2005, the urban population in the watershed area grew by 93.19%, which represents an urbanization rate of 6.3% per year.…”

“…In the lagoon, the sample sites were selected so that the water body was homogeneously represented according to its patterns of circulation and hydrodynamic dispersion (Silva, 2016). Thus, 6 sample sites were selected: two in the North, 2 in the Central region, and 2 in the South region.…”

Urbanization in watersheds leads to the introduction of sources of microplastics and other pollutants in water bodies. However, the effect of urbanization on microplastic pollution and the relationship between microplastics and water quality are not well understood. We assessed the distribution of microplastics in tributaries urbanized, non-urbanized and in the receiving lagoon body of Conceição Lagoon watershed.The results show that urbanization signi cantly affects water quality but does not differentiate tributaries in terms of microplastic concentrations. Microplastic concentrations were lower in the receiving lagoon body compared with the tributaries, highlighting their importance in microplastic pollution in the studied lagoon. Microplastic concentration was correlated with low N:P ratios in the lagoon and associated with high levels of total phosphorus, which indicate the discharge of e uents. The correlations between microplastic concentration, water temperature, and dissolved oxygen in the lagoon were based on the temporal variations of these variables. Precipitation and wind velocity had in uence on microplastic distribution in the watershed. Our ndings underscore the importance of evaluating water quality parameters and meteorological variables to comprehend the microplastic distribution at small watersheds.

“…A formação sócio-espacial da grande Florianópolis tem grande relevância ainda na produção de gramas, flores e folhagens. No início da década de 1990, a floricultura catarinense entrou definitivamente no mercado nacional, dominando o setor de paisagismo (AKI; PEROSA, 2002 apud SILVA; LOUREIRO; GALDINO, 2014). Em 2007, o estado de Santa Catarina possuía 372 produtores espalhados em 112 municípios (BUANAIN;BATALHA, 2007).…”

A formação sócio-espacial da Grande Florianópolis é composta por três microrregiões (Florianópolis, Tabuleiro e Tijucas) e conta com uma população de 994.095 mil habitantes, o que representa 15,1% da população do estado. A ocupação dessa formação regional realizada, entre meados do século XVIII e o primeiro quartel do século XIX, foi construída na base de uma pequena produção familiar que desempenhou papel significativo na divisão nacional/regional do trabalho da produção agropecuária. Em sua trajetória de ascensão e queda, parte dessa pequena produção transformou-se em verdadeiros negócios agropecuários. Apesar do elevado grau de urbanização, da expansão da mancha urbana a partir de Florianópolis, da redução da população rural e do avanço dos segmentos industriais e de serviços na geração de renda regional, verifica-se no conjunto da formação regional e em alguns municípios específicos uma importância significativa do Valor Adicionado Bruto gerado pela agropecuária. Desvendar o papel da produção agropecuária da formação sócio-espacial da Grande Florianópolis pós-2003 é o objetivo geral do texto. Esse dinamismo veio acompanhado de alterações significativas nas estruturas produtivas regionais, promovendo novas características via concentração da produção, exclusão, especialização e diferenciação social. Na elaboração deste texto, optou-se pela abordagem exploratória via levantamento bibliográfico e documental relativo à temática exposta e o levantamento de dados estatísticos.
