Environmental exposure to active pharmaceutical ingredients (APIs) can have negative effects on the health of ecosystems and humans. While numerous studies monitored APIs in rivers, these employ different analytical methods, measure APIs, ignored many countries world. This makes it difficult quantify scale problem from a global perspective. Furthermore, comparison existing data, generated for studies/regions/continents, is challenging due vast differences between methodologies employed....
Abstract Interactions between parasite, host and host-associated microbiota are increasingly understood as important determinants of disease progression morbidity. Salmon lice, including the parasitic copepod Lepeophtheirus salmonis related species, perhaps most problem facing Atlantic aquaculture after feed sustainability. lice parasitize surface fish, feeding off mucus, scales underlying tissue. Secondary bacterial infections a major source associated In this study we tracked diversity...
Water pollution by heavy metals is one of the leading environmental concerns as a result intense anthropogenic pressure on aquatic environment. This constitutes significant limitation to human right access drinking water. In this context, risk humans from exposure and arsenic in water rivers subject mining influence Central Andes Peru was assessed. samples were collected seven at 63 sampling sites, concentrations Cu, Fe, Pb, Zn, As determined using flame atomic absorption spectrophotometry....
Protected natural areas, especially regional conservation are important for preserving biodiversity, ecosystem services and recreation. The Huaytapallana Regional Conservation Area in the Junín region of Peru is a mountain providing hydrological, cultural, tourism to population. This study evaluated environmental impact visitors on two tourist trails (one vehicular one pedestrian) ritual zones this area using Leopold matrix. Sample plots were previously installed 20 × 25 m (subdivided into...
Abstract The cumulative effects of anthropogenic stress on freshwater ecosystems are becoming increasingly evident and worrisome. In lake sediments contaminated by heavy metals, the composition structure microbial communities can change affect nutrient transformation biogeochemical cycling sediments. this study, bacterial archaeal under fish pressure with metals were investigated Illumina MiSeq platform. Despite similar content most in lagoon sediments, we found that their different...
Toxic metal contamination, distribution and risk were evaluated in the sediments of three lagoons used for fish farming central region Peru. The toxic metals sediment was following descending order Zn > V Ni Cu Pb As Cr Co Cd Sb. Contamination factor (Cf) geoaccumulation index (Igeo) values Co, Cr, Cu, Ni, Pb, Sb, indicated low contamination moderate contamination. pollution load (PLI) ranged from 0.3856 to 0.5622; indicating no appreciable modified degree (mCd) corroborated this result....
In the present study, treatment of dairy industry wastewater using bacterial biomass isolated from eutrophic lake sediments was carried out to produce water for agricultural use. Microorganisms were sediment establish consortiums efficient in removal organic matter wastewater. The nature effluents varied according system and parameter evaluated. anaerobic treatment, chlorides, sulfates, phosphates chemical oxygen demand recorded highest average values. aerobic turbidity, electrical...
The COVID‐19 pandemic has provoked a worldwide mental health crisis, affecting university students in an exacerbated way, exposing them to the risk of emotional isolation and development eating disorders. present study aimed examine quality healthy lifestyle practices from Faculty Human Medicine Education Peruvian during after pandemic. This was conducted academic period 2020 2023. Data collection performed between July August 2020, first wave (M1) November December 2023, post‐pandemic (M2)....
In this study, the quality of sediment and surface water in two natural wetlands, Paca Tragadero, central region Peru was evaluated using pollution indices, including geoaccumulation index, pollutant load modified degree, potential ecological risk site rank for four heavy metals. Principal component analysis used to identify metal contaminant sources. The determination Fe, Zn, Pb, As performed by flame atomic absorption spectrophotometry. average concentrations metals sediments both lagoons...
The afforestation of grasslands can alter different ecosystems’ functional processes; it affects the water balance due to high demand, caused by increased productivity plantations, increase evapotranspiration, and reduces base flow basins. In Uruguay, there are two scenarios; headwaters Tacuarembó River, where area plantations has for more than 30 years, Río Negro, mainly preserved without significant changes. This article evaluates dynamics grassland in basins, through spatial temporal...
The acceleration of mineral extraction in many parts the world since early 2000s has raised concerns mining-related pollution. However, environmental harms mining are not always immediately visible, but rather accumulate gradually over time through processes slow violence. This article analyzes how violence, including material pollution, malleability companies' discourses and political practices state authorities' ambivalent regulation, shape local people's experiences suffering Peruvian...
The concentrations of As, Pb and Cd in leaves the most consumed medicinal plants central highlands Peru "eucalipto" - Eucalyptus globulus Labill "muña" Minthostachys mollis (Kunth) Griseb by inductively coupled plasma mass spectrometry (ICP-MS). composite foliage samples were collected areas districts Quilcas Saño province Huancayo. decreasing order mean toxic metals E. was > M. As Cd. In globulus, highest concentration (2.14 mg Kg‒1) recorded Quilcas, (0.39 (0.06 Saño. mollis, (1.84 PCA...
The concentration of Cu, Fe, Pb, Zn and As in the surface water intended for human consumption other uses Mantaro River basin were analysed using multivariate methods. samples collected from seven bodies Junín region June 2019, low discharge period. In each body water, a sector with six sampling sites was established. contents determined by flame atomic absorption spectrophotometry method. correlation analysis revealed positive significant correlations (P < 0.05) Zn/Pb, Pb/Fe Zn/Fe pairs...
In late December 2019, the emerging disease COVID-19 was identified as a global pandemic.Countries around world have implemented various types of blockades to stop this infection.These health measures led significant reduction in air pollution.However, impact these on aquatic environments has been little analyzed.In context, water quality rivers Mantaro River basin evaluated using multivariate statistical methods and heavy metal contamination indices during crisis pandemic.Surface samples...
Water quality is one of the determinants human well-being and ecosystem health. The increasing deterioration its most widespread worrisome environmental problems. In this context, dynamics water Cunas River in rural urban areas central region Peru during 2017–2019 was evaluated. A total 168 samples were collected from 56 sampling sites nine physicochemical parameters three heavy metals determined. results obtained reveal that did not exceed standards for water, except BOD5 Fe. Cluster...
Most Andean lakes and lagoons are used as reservoirs to manage hydropower generation cropland irrigation, which, in turn, alters river flow patterns through processes of storage discharge. The Carhuacocha Vichecocha lagoons, fed by glaciers, important aquatic ecosystems regulated dams. These dams increase the Mantaro River during dry season, supporting both energy production irrigation for croplands. Water quality was assessed between discharge events using Canadian Council Ministers...
