Confined within a sugarcane monoculture: A participatory assessment of water pollution and potential health risks in the community of El Tiple, Colombia.

Communities neighboring monoculture plantations are vulnerable to different forms of pollution associated with agro-industrial operations. Herein, we examine the case of El Tiple, a rural Afro descendant community embedded within one of the largest sugarcane plantations in the Americas. We implemented a participatory approach to assess water pollution, exposure via water ingestion, and non-carcinogenic health risks associated with the use of local water sources available to the community.

Resistance and induction of viable but non culturable states (VBNC) during inactivation of E. coli and Klebsiella pneumoniae by addition of HO to natural well water under simulated solar irradiation.

Inactivation of E. coli and Klebsiella pneumoniae by addition of HO 10 mg L into natural well water samples containing natural total iron concentrations (around 0.3 mg L) under simulated solar light was followed by bacterial culturability (plate count) and viability (DVC-FISH).

Photo-Fenton process at natural conditions of pH, iron, ions, and humic acids for degradation of diuron and amoxicillin.

Effect of ferric ions at concentrations typically found in natural waters (0.05 to 1.06 mg L) and low HO concentrations (between 0.

Addition of Hydrogen Peroxide to Groundwater with Natural Iron Induces Water Disinfection by Photo-Fenton at Circumneutral pH and other Photochemical Events.

Samples of natural groundwater (with low turbidity, neutral pH and 0.3 mg L iron concentration) inoculated with Escherichia coli K-12 were exposed to simulated solar light both in the presence and in the absence 10 mg L of H O Results demonstrated that the viability of E. coli (by DVC-FISH) was grounded to zero after 360 min of irradiation.

2,4-D abatement from groundwater samples by photo-Fenton processes at circumneutral pH using naturally iron present. Effect of inorganic ions.

This study evaluated, at laboratory scale, if the using iron naturally present (0.3 mg L) and adding 10 mg L of hydrogen peroxide was effective to remove 24.3 mgL of 2,4-dichlorophenoxyacetic acid (2,4-D) from groundwater samples by simulated solar irradiation (global intensity = 300 W m).
