Antifouling paint particles (APP) are considered highly toxic pollutants, whose presence has been reported in areas close to port activities, vessels, fishing, and maintenance. The present study aims to conduct a bibliometric study of the APP evaluation of Latin American and Caribbean research (original articles, conference papers, and reviews), published between 2011- 2023, in two of the most important global academic databases, Web of Science (WoS) and Scopus. The search chain and selection of documents identified 28 articles in WoS and 21 in Scopus. Brazil is the leading country in terms of publications on this topic. The articles report values as high as 40,300 µg/g of APP in sediments, containing metals such as Cu, Zn Si, Fe, Cr, and Pb among others. Butyltin diuron, Irgarol, 4,5-dichloro-2-octyl-1,2-thiazol-3(2H)-one (DCOIT), and other biocides are also reported. Further studies a...

This article aimed to carry out a systematic review of rainwater harvesting and storage systems (RWHSS) between 2012 and 2022. This study used the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA) as reviewing method. The systematic review process involved four stages: identification, screening, eligibility and inclusion. To carry out this research, the Scopus, ScienceDirect and Springer Link digital databases were consulted using the keywords “rainwater”, “storage”, “harvesting”, “rural”, “treatment”; initially obtaining 581 results, after filtering the information through PRISMA, 15 articles were obtained to carry out the analysis of the results linked to the questions raised in this work. The results showed that all the RWHSS have four main components: 1) Catchment area, 2) gutters, 3) pipes and 4) storage syste...

Most industries are responsible for environmental pollution because their wastewater contains heavy metals that are hazardous. These metals tend to persist indefinitely in the environment, compromising not only human health but also the well-being of ecosystems. The objective of this study was to analyze the adsorption technology for removing heavy metals in industrial wastewater, evaluating influencing factors, adsorbent materials, applied isotherms and their advantages, through a systematic review of the scientific literature of the last 10 years. To conduct this research, the Scopus digital database was consulted. The search was conducted using a systematic review methodology and the PICO framework to identify, analyze, and interpret data on adsorption technology, factors influencing adsorption, the efficiency of different materials used as adsorbents, and the advantages and disadvant...

Domestic wastewater from homes without sewerage is discharged directly into the ground, rivers or streams, which generates health and pollution problems. Septic tanks are used as an on-site treatment by a significant fraction of the world's population. This study aimed to evaluate the efficiency of domestic wastewater treatment using septic tanks with baffles implemented in rural households. The septic tanks were built and evaluated as part of a research project, focused on decentralized domestic wastewater treatment systems at the rural level. The septic tanks operated with detention times of 4.44; 2.67 and 1.90 days. The data was obtained through five monitoring campaigns with a fortnightly frequency, taking water samples at the entrance and exit of each septic tank. After sample collection, concentration levels of BOD5, COD, total suspended solids (TSS), nitrates, and phosphates were ...

Cleaner Production, as an environmental strategy, is integrated into processes, products, and services to increase efficiency and reduce risks to people and the environment. However, Cleaner Production management in water treatment services does not receive much public attention. To address this need, a scientometric analysis of the integration of Cleaner Production in water treatment was developed to investigate the efficacy and limitations of various Cleaner Production strategies applied in water treatment. A search was carried out in the Scopus database using the keywords "Cleaner production,’’ ``Wastewater treatment,’’ and ``Drinking water treatment’’ between January 1, 2002, and October 31, 2022. Through the scientometric analysis, it was possible to identify that Cleaner Production has been little applied in drinking water treatment. The reason for this was a systematic...

This study assessed a high Andean lake’s trophic state and water quality using methodologies with eutrophication and water quality indexes. Water samples were collected at six points in the lake, with a monthly frequency, for three winter and three summer months. Dissolved oxygen, pH, phosphates, nitrates, transparency, chlorophyll-a, fecal coliforms, biological oxygen demand (BOD), temperature, and turbidity were determined at each point. The trophic state of the lake was categorized by applying the Organization for Economic Cooperation and Development (OECD) eutrophication index, Carlson’s trophic state index (CTSI) and trophic index (TRIX). In addition, National Sanitation Foundation water quality index (NSF-WQI), Canadian Water Quality Index (CCME-WQI) and Oregon Water Quality Index (OWQI) were used to evaluate water quality. Results indicated that the lake had a high level of eu...
