Toxicity of micro or nanoplastics (MP/NP) in aquatic life is well-documented, however, information about the consequences exposure to these particles terrestrial species scarce. This study was used evaluate uptake and/or toxicity polystyrene MP/NP human gastric cells, comparing doses, particle sizes (50, 100, 200, 500, 1000 5000 nm) and surface functionalization (aminated, carboxylated non-functionalized). In general, 50 nm significantly higher than particles. Among particles, aminated were...
Anaerobic lagoons and treatment wetlands are used worldwide to treat wastewater from dense livestock production facilities; however, there is very limited data on the hormonal activity of effluent produced by these systems. The objectives this experiment were measure (1) initial (2) effectiveness a lagoon-constructed wetland system for producing an with low activity. Wastewater samples taken in April, July, November 2004 July 2005 at swine farrowing facility. Estrogenic (in vitro E-screen...
Endocrine disrupting chemicals (EDCs) impair living organisms by interfering with hormonal processes controlling cellular development. Reduction of EDCs in water an environmentally benign method is important green chemistry goal. One EDC, 17α-ethinylestradiol (EE2), the active ingredient birth control pill, excreted humans to produce a major source artificial environmental estrogenicity, which incompletely removed current technologies used municipal wastewater treatment plants (MWTPs)....
Microplastics have become a ubiquitous contaminant, but their fate in food animals is largely unknown. In this study, [
Abstract The public assumes that some foods, such as milk and ground beef from cattle receiving steroidal implants, are associated with estrogenic hormones, while other foods presumed “safe” or nonestrogenic. Here, we investigate these assumptions by assessing the relative activity of a serving size four foods: skim (8 oz), rice (48 g dry wt) in cooking bag, patties steers raised without hormone implantation (quarter lb each, 114 g), tofu burgers (isocaloric to burger, 198 using an vitro...
Micro/nanoplastics (MP/NP) are pervasive contaminants that detected throughout the environment in diverse matrices. Exposure to MP/NP have been demonstrated humans by their presence numerous body fluids and tissues. Due large quantity of production broad applications, polymethyl methacrylate (PMMA) frequently measured surveys microplastics environment. The effects size, surface charge (aminated, carboxylated or non-functionalized), concentration, exposure duration PMMA particles HepG2 human...
Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF), persistent pollutants that accumulate in the food chain, pose a risk to humans through consumption of tainted livestock. Clenbuterol, leanness-enhancing agent, was tested for usefulness PCDD/F body store reduction fat (the predominant site accumulation). To mimic situation contaminated animals, rats were given feed with or without mixture (0.6 2.7 ng/congener per day) 10 d, followed by 16 d dietary clenbuterol...
