Ecotoxicological Influence of Microplastics on the Hematological Profile of Brown Swiss Fistulated Cattle

Abstract

Bisphenol A (BPA) chemical compound used in the manufacture of plastics. The daily use and inappropriate disposal of plastics has increased disproportionately, the degradation of this generates plastic particles (microplastics). BPA belongs to a group of substances called endocrine disruptors that have the ability to alter the functions and systems of the body. The present study determines whether there is influence of microplastics on the hematological profile. In addition, the ecotoxicological concentration of BPA in microplastics is quantified. The technique of In situ degradability of nylon bags was applied. These were carried out in three stabled cattle of the Brown Swiss breed, male sex, with permanent fistulas in the rumen. Likewise, 16 parameters of the hematological profile were evaluated both in the pre-induction and post-induction of microplastics. From the Hematological Profile, only the Hematocrit parameter (HCT) presented a mean variation at the 0.05 level of significance in T2. The values in pre-induction (47.53 ± 1.29), post-induction (45.80 ± 1.87) and BPA concentration with values lower than 0.01 mg / kg. It can be presumed from the result, that microplastics do not influence the hematological profile in a significant way, due to the exposure time and quantity of microplastics.
