“…Due to its negative impact on human health, more countries are introducing bans or restrictions on the use of BPA [12]. Pollutants that exist in water have an impact on the surrounding environment and human health; therefore, it is necessary to test the quality of water and determine the presence of pollutants [13]. Canada was the first country in the world to officially recognize BPA as a toxic and dangerous substance to humans and the environment.…”

This paper presents a procedure for the determination of bisphenol A (BPA) in seawater. Gas chromatography coupled with mass spectrometry (GC-MS) was used as the analytical method, preceded by analyte isolation via solid-phase extraction (SPE). Initially, the best conditions for extraction, derivatization, and GC-MS analysis were established. The need for derivatization in the determination of BPA was investigated, and for this reason, two methods of sample preparation were compared: with and without the derivatization step. The parameters of the two methods of sample preparation were compared with each other, and a more efficient method was chosen for the analysis of marine water samples. Afterwards, the validation process was carried out and the following parameters were determined: limit of detection (LOD), limit of quantification (LOQ), linearity, precision, reproducibility, and repeatability. Finally, the results of the determination of bisphenol A in water samples collected from five harbor basins of the Port of Gdynia using an unmanned mobile research unit, HydroDron-1, were presented. The identified concentrations ranged from 0.01 µg/L to 0.03 µg/L, depending on the investigated area.

“…Water quality conditions directly affect public health and the economic productivity of nations [1][2][3]. Therefore, large-scale, accurate and fast water quality monitoring is particularly important [4,5]. Although on-site water quality measurements can obtain water quality parameters in detail, they are also time-consuming, labor-intensive, costly, and are easily restricted by weather and hydrological conditions, making it difficult to conduct timely, large-scale monitoring [6].…”

The combination of remote sensing technology and traditional field sampling provides a convenient way to monitor inland water. However, limited by the resolution of remote sensing images and cloud contamination, the current water quality inversion products do not provide both high temporal resolution and high spatial resolution. By using the spatio-temporal fusion (STF) method, high spatial resolution and temporal fusion images were generated with Landsat, Sentinel-2, and GaoFen-2 data. Then, a Chl-a inversion model was designed based on a convolutional neural network (CNN) with the structure of 4-(136-236-340)-1-1. Finally, the results of the Chl-a concentrations were corrected using a pixel correction algorithm. The images generated from STF can maintain the spectral characteristics of the low-resolution images with the R2 between 0.7 and 0.9. The Chl-a inversion results based on the spatio-temporal fused images and CNN were verified with measured data (R2 = 0.803), and then the results were improved (R2 = 0.879) after further combining them with the pixel correction algorithm. The correlation R2 between the Chl-a results of GF2-like and Sentinel-2 were both greater than 0.8. The differences in the spatial distribution of Chl-a concentrations in the BYD lake gradually increased from July to August. Remote sensing water quality inversion based on STF and CNN can effectively achieve high frequency in time and fine resolution in space, which provide a stronger scientific basis for rapid diagnosis of eutrophication in inland lakes.

“…De acordo com Chawla et al (2020), o uso do sensoriamento remoto para monitoramento de recursos hídricos pode ser feito a partir da avaliação de aspectos relativos à qualidade, quantidade, mapeamento e previsão de eventos extremos, possibilitando uma análise rápida e de baixo custo da dinâmica espaço-temporal envolvidas nos processos ambientais. Essa abordagem vem sendo comumente utilizada em vários trabalhos na área ambiental e foi empregada por diversos autores (GUTIERREZ et al, 2003;GUTIERREZ et al, 2017;MELLO et al, 2017;CECONELLO;CENTENO;GUEDES, 2018;XIANG et al, 2021;YIN et al, 2021;CUSTODIO;PEÑALOZA, 2021), de forma a estabelecer os efeitos das atividades antropogênicas, considerando as correlações entre parâmetros das matrizes ambientais impactadas.…”

O objetivo desta pesquisa foi verificar a correlação entre a qualidade da água do Rio Pirapora com as condições das Áreas de Preservação Permanente (APPs), por meio do uso do sistema de informação geográfica e dados de sensoriamento remoto. Portanto, para a avaliação foi considerada dados do monitoramento de qualidade da água disponibilizadas pela CETESB e do uso e cobertura do solo na bacia. Para a análise dos dados, foi utilizado como referência os valores da resolução do CONAMA e técnicas estatísticas de análise multivariada. Contatou-se correlação entre parâmetros de qualidade da água e uso e cobertura do solo para o ano de 2019, enquanto para os anos anteriores a análise não retornou resultados consistentes para refutar ou confirmar as correlações. Ainda, notou-se conflitos de usos nas APPs, sendo 40% das respectivas áreas sem cobertura vegetal, por fim, alguns parâmetros de qualidade da água não atenderam aos valores de referência.
