Origin and distribution of mineral species in limestone caves [PDF]

open access: yes, 1971
More than 80 mineral species are known to result from secondary chemical reactions in solutional limestone caverns. These minerals are transitional and end-products of carbonate wall rock interactions with ground water and organic residue.

Evaluation of a novel anti‐mycotoxin agent specific for aquatic species in mitigating aflatoxin B1‐induced changes in Nile tilapia: A comprehensive study

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract Aflatoxin B1 (AFB1) contamination of aquaculture feed poses serious health risks to fish and consumers. In this study, the efficacy of a novel anti‐mycotoxin agent specific for aquatic species (AM‐AQ) containing bentonite, sepiolite, and orange peel meal (Citrus Sinensis) in alleviating AFB1 toxicity in Nile tilapia (Oreochromis niloticus) was
