Cigarette smoke contains many chemicals that are harmful to both smokers and non-smokers. Breathing just a little cigarette can be harmful. There >7000 in smoke, at least 250 known of them cause cancer. Currently, studies reported the types organic compounds smoke; instead, there almost no works describe presence inorganic compounds. In this work, cost-effective self-made passive sampler (SMPS) was tested as tool collect different particulate matter (PM) from containing metals hazardous...
The objective was evaluate the carotenogenic activity of Dunaliella salina isolated from artificial salt flats municipality Manaure (Department La Guajira, Colombia). Two experimental testings were designed, in triplicate, to induce reversibility cell tonality depending on culture conditions. In first test (A), green red D. cells, these cultured J/1 medium at a concentration 4.0 M NaCl, 390 µmol m-2 s-1, 0.50 mM KNO3. second (B), tonality, cultures maintained 1 190 5.0 KNO3 and pH 8.2....
The accumulation of cyanobacteria produced due to eutrophication processes and the increment different pollutants in water as a result industrial affects aquatic environments such ocean, rivers, swamps. In this work, cyanobacterial biomass was used biosorbent for removal commercial dye, methylene blue (MB). Thus, MB removed from obtained samples collected swamp located Colombian Caribbean. Spectroscopical techniques FTIR, SEM, EDX measurements were physico-chemical characterization...
In this work, we studied the effect of TiO 2 sensitization with dry biomass extracted cyanobacteria on degradation methylene blue dye (AM). Cyanobacterial cultures isolated from water samples were collected swamp Malambo in Colombia; two main genera identified, and they cultivated BG-11 culture medium. The concentrations chlorophyll a exponential stationary phases growth measured; phycobilin content was quantified by spectrophotometry. Thin films deposited doctor blade method, sensitized wet...
Over the last decades, concern about air pollution has increased significantly, especially in urban areas. Active sampling of pollutants requires specific instrumentation not always available all laboratories. Passive a lower cost than active alternatives but still efforts to cover extensive The use biological systems as passive samplers might be solution that provides information assist decision-makers environmental health and planning. This study aims employ subaerial biofilms (SABs)...
La pandemia mundial causada por el coronavirus SARS-CoV-2 originó un impacto significativo en varios sectores de la sociedad, como ejemplo: salud, ciencia y economía, sobre todo cambio notable los aspectos ambientales. El presente estudio se centró análisis propagación del COVID-19 Sudamérica, destacando impactos las políticas bloqueo calidad aire principales ciudades 13 países durante pandemia; además, medio modelos estadísticos regresión simple caracterizó comportamiento casos acumulados...
Abstract Salt crystallization is one of the major problems currently faced by field architecture and construction. Its effects are devastating to extent that they may even lead loss material. Although many innovative resistant materials have been developed in last years, most constructions, salt a persistent problem. Salts crystallizations formed dissolution subsequent precipitation soluble salts present material itself or due formation new ones because reaction between original components...
We studied the growth and production of pigment microalgae Dunaliella salina cultivated in<br />photobioreactor multicamera oscillating outside laboratory conditions to evaluate effect different<br />concentrations zeolite (ZC). Growth was evaluated by cell count content performed<br />by spectrophotometric techniques. The results indicate that concentration 50 mgL-1 ZC produced<br />a better stimulus on microalga reaching maximum density (MDC) 5.51 ±0.45 x 106<br...
