Abstract

Zearalenone is a mycotoxin produced by some Fusarium species in food and feed. Toxicity of ZEA and its metabolites is related to the chemical structure of the mycotoxins, similar to naturally occurring estrogens. Currently, there is increasing awareness of the significance of fungi and their toxic metabolites in water. Thus it was considered essential to determine the concentration of estrogenic toxin in surface waters, groundwater and wastewater in Poland. The application of ZearalaTest immunoaffinity columns for zearalenone determination by HPLC method in water samples characterized by different natural organic matter (NOM) content gave the recovery rate ranging from 74 to 86%. Obtained results showed that the natural organic micropollutants of water with low molecular masses have an effect on zearalenone recovery. Zearalenone was present in water samples in the range from 0 to 43.7 ngL(-1).

摘要

玉米赤霉烯酮是由食品和饲料中的某些镰刀菌属产生的一种霉菌毒素。玉米赤霉烯酮及其代谢产物的毒性与霉菌毒素的化学结构有关，类似于天然存在的雌激素。目前，人们越来越意识到真菌及其有毒代谢产物在水中的重要性。因此，确定波兰地表水、地下水和废水中雌激素毒素的浓度被认为是至关重要的。使用ZearalaTest免疫亲和柱通过高效液相色谱法测定不同天然有机物（NOM）含量的水样中的玉米赤霉烯酮，回收率在74%至86%之间。所得结果表明，低分子质量的水中天然有机微污染物对玉米赤霉烯酮的回收率有影响。水样中玉米赤霉烯酮的含量在0至43.7 ngL(-1)之间。
