Evaluation of the destination of biological sludge in strawberry cultivation with tebuconazole applications

Ibero-American Environmental Sciences Journal

Strawberry cultivation is characterized by the indiscriminate use of pesticides, which can cause not only food contamination, but also the accumulation of waste in the environment and in man. Techniques that minimize residual concentrations in the products and environment are desired. The objective of this study was to evaluate the use of biological sludge in strawberry cultivation, its potential for degradation of the fungicide tebuconazole (TEB) in the soil, its influence on residual concentrations and its microbial activity in the soil.

Coal generation by copyrolysis: effects of temperature, N2 flow and sludge percentage

Ibero-American Environmental Sciences Journal

Copyrolysis (CP) is the cleavage of more than one biomass by heat in the absence of oxygen, which yields liquid, solid, and gas products. Coal constitution depends on copyrolysis conditions and on the process adopted. The combined effect of temperature, nitrogen flow, and percent composition of treated industrial effluent sludge from a rice processing plant (TIESRPP) with rice hulls (RH) for coal generation through CP was studied.

Analytical method optimization for study of difenoconazole degradation in substrate with addiction of treated activated domestic sewage sludge

Ibero-American Environmental Sciences Journal

Pesticide degradation in soils can be evaluated as a possible solution to minimize the effects of toxic action using recalcitrant compounds on cultivated food and the environment in which it occurs. A common and sustainable alternative is the use of treated sewage activated domestic sludge (TSS) as an adjuvant in soils. The objective of this work was to evaluate the influence of TSS on the degradation profile of a pesticide in the soil. Based on the hypothesis that the use of TSS in soils may influence pesticide degradation, a lab-to-field approach was implemented to determine toxic analyte decay using diphenoconazole (DFC), a triazole class fungicide.

Analysis of trace metals in domestic and industrial sewage sludges

Ibero-American Environmental Sciences Journal

The adequate disposal of sewage sludges containing toxic metals still is a challenge. Its application on agriculture has been the most common method around the world and is being considered one of the cheapest ways for disposing this sludge. In that sense, the goal of the current research was to characterize three types of sludge, two coming from industry and one, from domestic sources, through chemical characterizations and determination of the trace metals: lead, chrome, copper, nickel and zinc. These metals were determined by Flame Atomic Absorption Spectrometry.
