Quality assessment of soils requires knowledge of distinct pollutant sources and process that leads the enrichment of harmful substances, by natural or anthropogenic causes. Reference values to chemical substances contents are used to characterize polluted or contaminated areas based preliminarily on background values. A background value refers to ...

The cocoa (Theobroma cacao L) crop has become very important for Colombia in recent years, due to the increasing in cultivated areas and the exportation commitment of the national government. For 2018, there were in the country approximately 170,000 planted hectares. This species is cultivated between 20° north latitude and 20° south latitude, at a...

Nature and the environment are affected by various human industrial and/or urban discharges. Remediation for this problem requires first and foremost an in-depth analysis and an overall characterization of the intrinsic properties of the pollution-receiving environments. Secondly it is necessary to predict in these environments the behavior of dang...

In this study, commercial cellulose membranes were surface coated with alpha‑zirconium phosphate nanoparticles (α-ZrP-n) to study their impact on the overall removal efficiency of heavy metals from synthetic metal mixture wastewater solution. A total of four homogeneous solutions (0.25, 0.50, 0.75, and 1.00 wt%) of α-ZrP-n were prepared by sonicati...

A brick pavement, tramped by humans, is exposed to atmospheric elements, thus allowing cyanobacteria and algae to colonise. In this article, we report on the factors that contribute to the slipperiness of a brick pavement at the University of Venda in the Limpopo province of the South Africa. Samples were collected from brick surfaces either coloni...

Introduction: Diseases such as asthma and lung cancer are associated with heavy traffic in urban areas. A deep understanding of the pollutants generated by road traffic is relevant to public health control.Objective: To analyze the correlation between vehicular traffic intensity and heavy metal concentrations in road sediments in the city of Bogota...

We analyzed the behavior of heavy metals, such as Cd, Cr, Cu, Ni, Pb, Zn, and Hg, in air pollution control devices of a municipal solid waste incinerator. For this study, a municipal solid waste incinerator with a burning capacity of 2,400 kg/h was selected. A semi-dry reactor (SDR), fabric filter, and wet scrubber were installed to serve as air po...
