“…High concentration of heavy metals on soil surface has an adverse effect on the microorganisms present in the soil as well as human beings. The illness rate of adults and teenagers as a result of diseases caused by heavy metals was found to be 1.4 -4.5 times and that of children under the age of 14 years was found to be 1.5 -3.9 times higher in areas contaminated with heavy metals [12,13]. Therefore similar assumptions can be made regarding the accumulation of heavy metals in bottom sediments and water bodies.…”

Agricultural activities, discharge of raw sewage into farms and the rise in urbanization have greatly contributed to soil pollution. During the rainy season, surface runoff from farms find their way into water bodies and deposits these contaminants into Rivers and Lakes which poses a threat to both aquatic and terrestrial organisms that depend on that water source. The objective of this research was to determine the level of anions and heavy metals from sediments in River Sio, Busia County, Kenya. Five sediment samples were taken from five sampling points and the levels of anions and heavy metals in them determined. Anions were determined using Shimadzu 1800 UV/visible spectrophotometer while heavy metals were determined using Shimadzu 6200 flame atomic absorption spectrophotometer (AAS). Copper, lead and nickel were above the allowed WHO limits while cadmium was below detection limit. The levels of nitrates, phosphates and chlorides were higher during the wet season due to surface runoff that carried these nutrients from the farms and deposited them on the bottom of the River. The levels of heavy metals were high during the dry season due to evaporation of water from the River, leading to an increase in the analyte concentration during the dry season. High levels of copper and nickel in the sediments points to the use of herbicides and pesticides in farming and washing of vehicles and motorcycles on the banks of the River. According to Igeo nickel showed moderate pollution during the dry season. The contamination factor for lead was very high during the dry season, while pollution load index confirmed pollution due to anthropogenic activities in sampling sites 1 – 4 during the dry season and no pollution due to anthropogenic activities during the wet season. The study recommends reduced use of inorganic fertilizers in order to save the River from the danger of eutrophication. Excessive use of agrochemicals such as herbicides and pesticides should be discouraged. In addition, pesticide leaching and the level of microbes in soil and sediments should be considered for further research

“…Results of studies of heavy metals (Pb, Cu, Zn, Ca) in contaminated areas of Lithuania showed that morbidity of adults and adolescent is 1.4-1.5 times higher and morbidity of children younger than 14 years 1.5-3.9 times higher than average morbidity of children with the same disease in uncontaminated regions of Lithuania (Juozulynas et al, 2008). In cities where the architecture is dominated by apartment buildings children most of their free time spend playing in outdoor playgrounds.…”

The soil contamination by heavy metals in playgrounds of kindergartens in Vilnius city is analysed in this article. The aim of this research is to investigate and evaluate soil contamination by heavy metals in playgrounds of kindergartens in different territories of Vilnius city. Concentrations of heavy metals were measured using Thermo Fisher Scientific Niton® XL2 X-ray fluorescence spectrometer. Maximum allowable and background concentrations that are given in Lithuanian hygiene standard and Lithuania geochemical atlas are used to compare and evaluate concentrations of heavy metals. Concentrations of heavy metals and their spatial distribution were analysed in order to exclude the most contaminated areas relating with different functional areas of the city. Geo-statistical analysis and maps of spatial distribution were developed using IDW interpolator in ArcMap software. Detail soil surveys helps to assess the extent of anthropogenic impact in different parts of the city which can be harmful to the soil ecosystem and human health. Such researches can help to change or select different function for city areas in territorial planning process.

Por lo tanto, la biodisponibilidad de los metales pesados representa un riesgo latente a la salud (Juozulynas et al, 2008;Yang et al, 2016), pudiendo afectar al sistema digestivo, nervioso e incluso se les relaciona con el cáncer, siendo los niños el grupo de edad más vulnerable a sus efectos (Benselhoub et al, 2015;Latif et al, 2014).…”

RESUMENLas actividades antropogénicas aumentan la movilización y distribución de los metales pesados, si se rebasan los estándares permitidos por la normativa internacional resultan un serio problema para la salud de los seres vivos y el medio ambiente. Uno de los casos más alarmantes es el del arsénico; su presencia en agua potable y suelos (y por ende en alimentos) es tal que hay reportados cientos de casos de intoxicación severa en países como China y Bangladesh. Debido a las actividades mineras, en algunas zonas de México como el Estado de Chihuahua, también se han encontrado altas concentraciones del elemento. Por el peligro que representa, la necesidad de encontrar alternativas para la remediación de sitios contaminados con arsénico es de suma importancia. Si bien existen diversos métodos físicos y químicos que se han usado desde hace décadas, la biorremediación constituye una alternativa prometedora que ofrece ventajas económicas y es ef iciente. Esto último se debe a que se han aislado microorganismos que pueden resistir altas concentraciones de arsénico e incorporarlo a procesos metabólicos específ icos gracias a mecanismos como la enzima arsenito oxidasa (AOX). Aún cuando el sistema de oxidación del arsénico no se ha descifrado completamente ha sido posible identif icarlo en un gran número de microorganismos a través de técnicas de ingeniería genética, mismas que de manera reciente se han utilizado para potencializar la capacidad de las cepas silvestres. El objetivo de este documento consistió en hacer una revisión general sobre la biorremediación del arsénico y algunas estrategias como la detoxif icación de arsénico (III) por medio de AOX con el f in de encontrar una solución factible al problema detectado en el estado de Chihuahua. Tras la vasta cantidad de información recabada se determinó que la ingeniería genética resulta una herramienta prometedora para lograr la biorremediación de los metales pesados y que integrar los genes aox, en microorganismos conocidos parece ser una alternativa viable para disminuir la contaminación por arsénico en cualquier sitio contaminado, por lo tanto, debe comenzarse con las pruebas de remoción y toxicidad cuanto antes.Palabras clave: detoxif icación, contaminación ambiental, ingeniería genética, metales pesados, enzima.
