Pharmaceuticals are considered as contaminants of emerging concern, and their occurrence in diverse environmental matrices has been described during the last 25 years. Nonetheless, pharmaceutical occurrence has not been evenly described worldwide, and reports from some geographical areas such as most parts of Latin America are scarce. This work aims to address the situation of water pollution due to pharmaceuticals in Latin America by means of two main goals: i.

The use of finely ground rice husk as a microcarrier and co-substrate permitted a marked increase (≈ 2.7×) in the productivity of fungal pellet production using Trametes versicolor compared to traditional production methods.

- Pharmaceuticals are emerging pollutants, particularly in Central America, where their presence in farm wastewater and surface waters has been under-researched, especially in relation to dairy farming.
- In a study, wastewater samples from seven dairy farms detected eight pharmaceuticals, with several posing high to intermediate risk based on ecotoxicological assessments that indicated toxicity to certain aquatic organisms.
- Surface water samples revealed even more concerning results, with 14 pharmaceuticals found and a significant portion posing high environmental risks, highlighting a growing issue of pharmaceutical contamination in agricultural areas.
