“…These observations concur with the PCA result, which showed that Al, Ba, Mn, Sr, Ti, and V may be from the same sources. Thus, the PTEs in groups one and two of the cluster are probably from anthropogenic or paedogenic sources [24].…”

“…A total of ninety three soil samples were collected. Approximately 50 g of soil samples were transferred into polyethylene bags, and subsequently transported to the laboratory and air-dried at room temperature for two weeks [24]. Before the determination of PTEs, substantial impurities were detached from the air-dried soil samples, pulverized using a mortar and pestle, and sieved viaa U.S. No.…”

Cement plants are the major anthropogenic sources of potentially toxic elements (PTEs), which are generated from the processing of raw materials and combustion of fossil fuels. This study determined the PTE concentration and assessed the geochemical, ecological, and health risks associated with the activities in the Ashaka cement plant, Bajoga, Nigeria. Soil samples were collected between 2019 and 2020, and analyzed by ICP-OES for 20 PTEs. The data obtained were statistically evaluated for descriptive and inferential statistics. The mean concentrations of PTEs were in the declined order of Al > Fe > Mn > Zn > Ti > Ba > Sr > Pb > Cu > V > Cr > Ni > As > Sc > Mo > Hg > Cd > Se > Sb > Co. Multivariate analysis revealed that the main sources of PTEs might be related to anthropogenic activities from cement plant. The geochemical load index (GLI) values obtained range from unpolluted to moderate. The ecological risk ranged from 4.74 × 10− 3 to 8.00 × 100, and the overall risk index indicated low contamination for the investigated elements. The hazard index (HI) was < 1, suggesting non-probable non-carcinogenic effects. However, children were more susceptible to risk than adults, and the cancer risk (CR) values of Cd for children and adults were higher than the threshold level of 1.0 × 10− 4, which suggests probable development of cancer risk for residents.

One of the monumental environmental and public health concerns of our time lies in the use of toxic preservatives in wood treatment plants. In this investigation, we report the results of potentially toxic heavy metals from wood treatment plants in Uasin Gishu County. A 20 g ground and sieved soil sample from each sampling site Cheplaskei (CK), Outspan (OS) and Sukunanga (SK) was weighed and treated with 0.5 M nitric acid for 2 h. The sample was then analyzed for potentially toxic metals using inductively coupled plasma atomic emission spectroscopy (ICP-AES). The statistical treatment of the data was done using Principal component analysis (PCA) and Pearson’s correlation. The highest concentration of copper was observed at SK, which contributed approximately 37% of all the potentially toxic heavy metal content analyzed, whereas the concentration of lead was found to be about 33% of the total heavy metal content analyzed at the same sampling site. Furthermore, the most abundant metal in the sampled sites is manganese, which was found to be 390.0 ± 8.63, 279.0 ± 8.05and 44.5 ± 2.95 ppm in OS, CK, and SK, respectively. PCA showed that the heavy metals in the sample sites originated from two independent sources—natural and anthropogenic. Evidently from the concentration profile data, all the potentially toxic heavy metals had concentrations above the World Health Organization (WHO) acceptable limits, although, based on the contamination factors determined, the wood treatment sites are less polluted; however, there is need for regular monitoring to ensure adherence to proper public and environmental health practices.

“…Adicionalmente, o sedimento pode consistir em sumidouro bem como em fonte de EPTs, devido à capacidade de complexação desses oligoelementos com matéria orgânica, sulfetos e demais formas particuladas (LI, J. et al, 2023). Portanto, a avaliação da presença de EPTs em um corpo d'água é de extrema importância, por serem considerados um dos contaminantes ambientais mais nocivos devido aos seus potenciais de toxicidade, acumulação e não biodegradabilidade, que resultam em efeitos ecológicos negativos e riscos à saúde de seres vivos que estabelecem contato com o ecossistema contaminado (LI, Q. et al, 2023;OBAYOMI et al, 2023). Alguns EPTs são essenciais do ponto de vista biológico, mas quando em níveis acima do tolerável para organismos vivos, podem promover impactos negativos nos ambientes (JOSHI et al, 2022;CARVALHO et al, 2022).…”

A presença de elementos potencialmente tóxicos (EPTs) em ambientes aquáticos merece atenção, principalmente devido aos efeitos adversos que podem acarretar na qualidade das águas e, à saúde ecológica e humana. Neste contexto, este estudo teve como objetivo a análise e avaliação de EPTs em águas e sedimentos do rio Sorocaba em diferentes pontos amostrais distribuídos pela sua extensão urbana. As quantificações dos elementos foram realizadas por espectrometria de emissão atômica por plasma de microondas (MP-AES), após digestão ácida das amostras. Os EPTs Al, Fe e Mn estavam acima dos valores máximos permitidos (VMPs) por legislações brasileiras para águas e, As, Cu e Cr acima dos VMPs para sedimentos. Com base nos referidos resultados bem como na avaliação do uso do solo no entorno dos locais amostrados, é possível evidenciar que as elevadas concentrações de EPTs são, provavelmente, oriundas e/ou intensificadas por atividades antrópicas. Adicionalmente, o índice Fator de Enriquecimento (FE) aplicado, indicou enriquecimento antrópico moderado para As, Cr, Cu e Zn em três pontos da área de estudo, e muito elevado para Zn em um local. A presente investigação alerta quanto a parâmetros de atenção que devem ser investigados no ecossistema, uma vez que o rio Sorocaba já foi submetido a um programa de despoluição de suas águas.
