Polystyrene (PS) is one of the main synthetic polymers produced around world, and it present in composition a wide variety single-use objects. When released into environment, these materials are degraded by environmental factors, resulting microplastics. We investigated ability
Abstract BACKGROUND Fipronil is a broad‐spectrum insecticide that used extensively due to its effective action in pest control. However, environmental studies have shown it has high toxicity towards non‐target organisms as well. In addition, the degradation of fipronil can generate even more toxic and reactive metabolites environment. present study, bioprospecting for bacteria with potential degrade was performed using sole source nitrogen main carbon. From samples corn culture soil history...
Acrylonitrile-butadiene-styrene (ABS) is a thermoplastic copolymer commonly used in the electronics, automotive, and construction industries. In aquatic environment, formation of microplastics from larger-sized plastic waste occurs naturally, induced by physical, chemical, biological processes that promote aging these particles. Here, we investigated interactions between freshwater amphipod Hyalella azteca ABS (10–20 μm) (pristine after accelerated aging) over 7 days exposure. At end...
ABSTRACTFreshwater environments are especially susceptible to microplastic contamination due their proximity urbanised and industrial areas. Also, there is a lack of information about the effects this pollutant on freshwaters making it difficult conservation these environments. Benthic species, such as freshwater amphipod Hyalella azteca, have been superficially studied so far for evaluation pollution. In present study, we analyzed whether polyethylene terephthalate (PET) microplastics could...
Microplastics are widespread pollutants in the environment and considered a global pollution problem. mostly originate from larger plastics due to environmental conditions undergoing constant fragmentation processes. It is important understand pathways, since they play key role fate of particles, also directly influence toxicity. Amphipods potential inducers plastic debris fragmentation. Here, Hyalella azteca was exposed different concentrations (540, 2700, 5400 items/L) 24.5 µm polystyrene...
Fipronil is an insecticide widely used in the agricultural and veterinary sectors for its efficacy pest control. The presence of fipronil environment mainly due to domestic practices frequently found different types environmental matrices concentrations ranging from µg/L mg/L can be hazardous non-target organisms high toxicity. This study was carried out obtain characterize microorganisms soil which are capable biodegrading that could great biotechnological interest. For this purpose, a...

IntroductionIn 2002, the Surviving Sepsis Campaign defi ned a strategy that aimed to reduce high mortality due sepsis.One point of this was recommendation recognize sepsis is frequent cause death and economic costs in pediatric intensive care unit.Knowledge disease fi rst step impact it.There are few studies on epidemiology world none Colombia.Hypothesis The epidemiological features Colombian children diff erent from other countries.Methods We constructed website where 14 units across...
Abstract Aquatic environments are especially susceptible to microplastic contamination. This is mainly because these water bodies serve as a transport route for particles from the terrestrial environment until they reach oceans. Also, there lack of available data about effects this pollutant on freshwaters making difficult conservation environments. Benthic species, such freshwater amphipod Hyalella azteca , have been superficially studied so far. Considering its essential role in trophic...
Azole compounds, such as ketoconazole (KTZ), have become problematic in aquatic ecosystems recent years. This chapter aimed to identify the effects of environmentally relevant concentrations KTZ on primary producer and consumer organisms, Raphidocelis subcapitata Ceriodaphnia dubia, respectively. Considering chronic assays, high sensitivity was identified for C. dubia organisms (EC50.192h = 2.5 µg/L) compared R. (IC50.120h 7.2 µg/L). Changes reproductive rate were observed over exposure KTZ....
Ketoconazole (KTZ), a broad-spectrum fungicidal drug, has been significant problem in recent decades due to its toxic action on non-target aquatic organisms. Thus, the present study aimed determine effects that sub-lethal concentrations of commercial formulation KTZ can exert benthic macroinvertebrates, more specifically larvae insect Chironomus sancticaroli. Acute toxicological tests with indicated LC50 9.9 µg/L. Analyzes prolonged exposure (chronic) an increase rate mentum deformity by...
Abstract Microplastic (MP) is yet another form of chronic anthropogenic contribution to the environment. MP are plastic particles (< 5 mm) that have been widely found in most diverse natural environments, but their real impacts on ecosystems still under investigation. Here, we studied toxicity naturally aged secondary polypropylene (PP) after constant exposure ultraviolet radiation (26 µm) larvae Chironomus sancticaroli, a dipteran species. The concentrations tested were 13.5; 67.5; and...
