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 Phytate is an important antinutritional component of legume seeds, which chelates minerals that are essential to the human diet such as iron and zinc. levels often correlated with total seed phosphorus (P). The objective this research was evaluate quantitative trait loci (QTL) for P phytate content in inter‐gene pool (G2333 × G19839) recombinant inbred line population common bean ( Phaseolus vulgaris L.) planted at medium high soil randomized complete block experiments. Seed were...
A system for automatic quantification of total phosphorus (TP) through hyperspectral analysis in soil samples enriched with fertilizer (P2O5) is presented. The acquisition protocol was described (Rivadeneira-Bolaños et al. 2023) and involved the design, development, construction a platform on which capture device (Bayspec OCI-F camera) installed. design lighting ensured adequate frequency response visible (VIS) near-infrared (NIR) regions, covering spectral range 420 to 1000 nm, preparation...

A preliminary evaluation of Semivolatile Organic Compounds (SVOCs) was performed in the atmosphere Santiago de Cali, Colombia, using passive air samplers based polyurethane foam (PAS-PUF) disks. PAS-PUF were deployed four sites, along a north-south transect(∼15 km), during one sampling period ∼4 months 2011, form industrial area Yumbo (EF site) to agricultural Valle del Cauca (FCNE). Results showed, for PCBs and PAHs, clear (IN > AG) decreasing concentration gradient (∼3 times) while OCPs...
Introduction: Exposure to pollutants such as pesticides and heavy metals has been linked health problems. Several studies have revealed the presence of these contaminants in Cali; however, there is no information available about main routes exposure risk contaminants.Objective: To estimate associated with intake cadmium, lead mercury, 2,4-D diuron through consumption water food a population Cali.Materials methods: Population environmental data were obtained, assessment was performed using...
Pine bark is a rich source of natural polyphenols, compounds which have attracted increasing attention in the fields nutrition, health and medicine. Extractive components include large amounts phenolic compounds. The ethanolic extract was obtained from Pinus patula grown forests Cauca Department Colombia South America. Gallic acid, catechin, epicatechin procyanidin B2 contents were 3.12, 1.99, 0.80, 0.71%, respectively, these determined using HPLC with UV-Vis detection. Ethanolic divided...
Controlled release formulations of Ruta essential oil obtained by ionic gelation were developed. The presence rue in the alginate and chitosan capsules was evidenced Fourier transform infrared spectroscopy differential scanning calorimetry. Release studies revealed that acidic conditions (pH 4.2), CHS-REO particles reached a Sw 240% (w/w) 30 days 101% for ALG-REO particles, generating RR 23.7% 20.4% ALG-REO. On other hand, at pH 6.8 it favored 840% therefore (45.6%) disfavored low (16.9%)....

La metodología QuEChERS fue implementada para la extracción de catorce plaguicidas, diez organoclorados y cuatro organofosforados en muestras suelo.El análisis se llevó a cabo por cromatografía gases acoplado una trampa iones cuadrupolar tándem (MS 2 ).La los plaguicidas seleccionada ve afectada diferentes factores, tanto, optimización del proceso incluyó el uso dos diseños experimentales: un diseño ortogonal Taguchi inicial determinar factores mayor influencia posteriormente, factorial...
Corn is one of the most consumed cereal in world; like crops, use pesticides to control plagues main tools used durig its production.Because presence these compounds food can endanger human health, analysis residual pesticide an important aspect security.The objective this work was evaluate extraction methodology QuEChERS seven (Dichlorvos, α-BHC, β-BHC, Diazinon, Disulfoton, Chlorpyrifos, Endosulfan I) into white corn grains variety Amylase.The procedure involved initial phase using 10.0 g...
