“…Industrial wastewaters contain a complex range of organic pollutants including dyes, detergents, oils, and other organic compounds (8), some of them being carcinogenic and exhibiting other side effects (9). Domestic wastewater is also not considered innocuous and often contains trace levels of pharmaceuticals and personal care products (PPCPs) (10) among others (11).…”

Water reuse is becoming increasingly important as more and more areas in the world are facing water stress issues. Treatment of wastewater to attain the purity required for various usages from culture irrigation to drinking water is therefore key. Several water treatment options are already in place and while we will continue to use them, parallel efforts are required to: (i) address the removal of the most persistent chemicals in water and (ii) provide solutions for local communities. Recently, several studies on the use of metal-organic frameworks (MOFs) for the adsorption and photocatalytic degradation of organics in water have been reported. This enthusiasm originates from the large porosity and chemical tunability of MOFs -beneficial for adsorption -as well as their catalytic nature -beneficial for degradation. The present reviews proposes a comprehensive and critical analysis of the most recent studies on the use of MOFs for organics adsorption and photocatalytic degradation. The potential to use MOFs to catalyze the production of H2 from organic molecules, like water contaminants, is also addressed. Overall, the discussion is organised based on the type of organic pollutants targeted and encompasses those released in industrial, domestic and agricultural wastewater streams.3

“…Total 140 patients were interviewed in two months of data collection where male and female ratio was 1:1. A similar study was done at the National Institute of cancer research and hospital (NICHR) in 2006 [33,34]. In this study, data was first analyzed in univariate approach and then multivariate approach (using partial least square path model).It has been observed that the highest number (54.23%) of patients were in 41-60 years age group, followed by 33.38% in 21-40 years age group [22].…”

Background: Cancer is one of the major killer diseases throughout the world. Cancer effected people are increasing very rapidly in the developed countries as well as developing countries. Usually causes of cancer have already been known in the world, however it's still unknown epidemiologically that what's the extents of heritability and environmental effects on cancer diseases. Many studies have been performed to uncover the reasons of cancer; however, to the best of our knowledge none study has been performed to know the extents of environmental (Body Mass Index (BMI), exercise, food preferences etc.) and heritability (blood connected people who are suffering from cancer or died because of cancer) effects on cancer. Methods:A cross-sectional study was conducted to collect the data of this study. Data were collected using a purposive sampling named 'snowball sampling' based on a semi-structured questionnaire from the cancer patients in Sylhet, Bangladesh visiting home, hospital, oncologists chambers. We have collected data total two months. Descriptive statistical tools were used for univariate analysis and Partial Least Squares Path Model (PLSPM) was used for multivariate analysis. Results:We found total 140 patients and ratio of male and female patients are 1:1. Results show that average age of male is 54 years and female is 48 years; average BMI of male is 23.91 and female is 24.38. Most of the Male patients are affected by lung and stomach cancer followed by throat and liver. And most of the female patients are affected by breast cancer followed by stomach, ovary and liver cancer. The results of PLSPM show that extent of environmental effect (path coefficient=0.37) is more than the heritability effect (path coefficient=0.15). These revealed that higher BMI, less exercise, and taking more junk food and meat might be the more influential factors for cancer. Conclusion:Taken together, we may conclude that the extent of environmental effect is higher than that of heritability effect. It's also clear that cancer patients are increasing in Sylhet city. Therefore, we should conscious about taking food (i. e; taking fresh vegetables, fish, etc. and should avoid fatty foods). Taking care of our body weight and doing exercise regularly.

“…Los colorantes son compuestos altamente coloreados y difíciles de descomponer biológicamente [1], los desechos de pigmentos en aguas residuales se consideran un tipo de contaminante objetable debido a su alta toxicidad tanto para el ecosistema como para la salud humana [2]. Esto ha creado una gran preocupación medioambiental acerca de las condiciones de los cuerpos de agua, lo que ha llevado a la necesidad de buscar técnicas eficaces para remover estos pigmentos de los efluentes y solucionar los problemas de contaminación [3].…”

Remoción de azul de metileno de soluciones acuosas utilizando cáscara de yuca (Manihot esculenta) modificada con ácido fosfóricoRemoción de azul de metileno de soluciones acuosas utilizando cáscara de yuca (Manihot esculenta) modificada con ácido fosfórico RESUMENEste trabajo reporta la modificación de la cáscara de la yuca con ácido fosfórico para la remoción de azul de metileno de soluciones acuosas. Se utilizó una metodología experimental con diseño compuesto central 3^2+estrella, variando la temperatura de modificación de la cáscara de yuca (113°C a 127°C), la relación biomasa-ácido fosfórico (1:0.5 a 1:1.5) y la concentración inicial del colorante (100 a 800 mg/L), utilizando como variables de respuesta el porcentaje de remoción y la capacidad de adsorción. Se encontró que, para el porcentaje de remoción del colorante, la variable más importante es la temperatura y que la capacidad de adsorción se favorece a concentraciones altas de colorante. La cáscara de yuca modificada a la temperatura más alta (127°C) y relación másica de biomasa-ácido 1:1 presentó mayores valores tanto para el porcentaje de remoción como para la capacidad de adsorción, los cuales fueron de 99.984% y 79.975 mg/g, respectivamente. La cinética de adsorción se ajustó al modelo de pseudo segundo orden lo cual sugiere que el proceso se realiza por quimisorción, además, ajustó con las isotermas de Freundlich, lo que sugiere que la adsorción se realiza en múltiples capas.Palabras clave: Cáscara de yuca; Azul de metileno; Remoción; Adsorción; Cinética; Isotermas de equilibrio. ABSTRACTThis work reports the modification of cassava peel using phosphoric acid for the removal of methylene blue from aqueous solutions. A central composite design 3^2+star was employed using as manipulated variables the temperature of modification (113 ° C to 127 ° C), the biomass-phosphoric acid ratio (1: 0.5 to 1: 1,5) and the initial concentration of dye (100 to 800 mg/L); the response variables of the experiment were the percentage of removal and the adsorption capacity. It was found that for the percentage of removal of dye, the most important variable is the temperature, and that the adsorption capacity is favored at high concentrations of dye. The cassava peel modified at the highest temperature (127 ° C) and biomass:acid mass ratio 1:1 showed higher values for both the removal percentage and the adsorption capacity, which were 99.984% and 79.975 mg/g, respectively. The adsorption kinetics was best adjusted to a pseudo second order kinetic model, which indicates that the process is carried out by chemisorption, also, the process was adjusted to Freundlich isotherms, indicating that the adsorption is carried out in multiple layers.
