“…É expressivo também a participação de usos passíveis de causarem alteração na qualidade ambiental nas matrizes de solo e água, identificados como, infraestrutura urbana e mineração. O número de classes identificadas para esse trabalho é próximo ao número de classes identificadas por Marzola et al (2019), que identificaram 13 padrões de uso do solo ao longo do perfil longitudinal do rio Pirapora, sendo mineração e silvicultura os padrões mais relevantes e que tiveram maior correlação em algumas das sub-bacias estudadas pelos autores, que visavam a identificação de metais nas águas do rio, associados a fontes de contaminação e padrões de uso e ocupação do solo. Realizou-se a análise de ACP com o objetivo de verificar quais parâmetros possuíam correspondências e maior representatividade no conjunto de amostras.…”

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.

“…Multivariate statistics techniques (e.g., principal component analysis, correlation analysis) are powerful tools for pollution source assessments [ 4 , 24 ]. These techniques were applied for the investigation of pollutants in soil, sediment [ 25 , 26 , 27 , 28 ], and natural waters [ 29 , 30 ].…”

Chemical analysis was performed on sediment samples collected in two sampling sessions (July and October) from Podu Iloaiei Dam Lake, one of the most important water resources used for aquaculture in north-eastern Romania. The concentration of 15 trace elements (TEs), 8 refractory elements (REs), and 15 rare earth elements (REEs)—determined using inductively coupled plasma mass spectrometry—showed variability largely dependent of the sampling points and collection time. Manganese was the most abundant TE, V and Cr were the most abundant REs, while Ce was one of the most abundant REEs. The cerium negative anomaly and Gd positive anomaly were observed in the Chondrite-normalized distributions. In October, the Ce anomaly showed significant negative correlation with Mn, emphasizing the water body oxidation potential. The identified positive Gd anomaly was most likely associated with the use of Gd-chelating agents in magnetic resonance imaging in Iasi, the largest medical hub in north-eastern Romania. Principal component analysis extracted three factors explaining 96.0% of the observed variance, i.e., rock weathering, leaching from soil surface, contributions from urban stormwater and atmospheric deposition (50.9%), pedological contributions (23.7%), and mixed anthropogenic sources (e.g., traffic, waste discharge, agricultural activities; 21.4%). The evaluation of pollution indices highlighted low and moderate degrees of contamination for most of the elements and a considerable degree of contamination for Cd. Assigned Cd sources included fertilizers and pesticides used in the near agricultural areas or the high traffic road located near the lake. Since contamination of aquatic ecosystems with harmful elements is a human health concern, further monitoring of specific vectors in the food chain of the investigated dam lake will be of the utmost importance.

New approach for determination of Cd, Cu, Cr, Ni, Pb, and Zn in sewage sludges, fired brick, and sediments using two analytical methods by microwave-induced plasma optical spectrometry and induced coupled plasma optical spectrometry

Microwave-induced plasma optical spectrometry (MIP OES) and induced coupled plasma optical spectrometry (ICP OES) were implemented in parallel for the determination of Cd, Cu, Cr, Ni, Pb, and Zn in sediments, as well as in unexplored matrices such as sewage sludge and fired brick. Initially, a microwave-assisted digestion procedure was applied to solubilize the samples. A selective approach has recommended for the detection of elements with low and high concentration ranges in different environments to improve sensitivity. Limit of detection (LOD) and limit of quantification (LOQ) were found between 0.026-0.039 mg L −1 and 0.08-0.11 mg L −1 , respectively. Precision and trueness were controlled using certified reference materials with the same matrices for all analysts. MIP OES showed results in accordance with ICP OES and LOD in the same range (or better, i.e., Pb) than ICP OES. MIP OES found a potential alternative with comparable performance and reduced costs for the analysis of trace metals.
