Ingredients in home and personal care products, including UV filters and benzotriazoles, are high production volume chemicals extensively used in our daily life, despite several studies revealed their potential eco-toxicity and endocrine-disrupting capacity. Due to some features, such as high lipophilicity, low degradability, and persistence of many of these compounds, sediments can be considered a sink for them in the aquatic environment. In the present study, nine organic UV filters and three benzotriazoles were investigated for the first time in sediments from four urban rivers in Brazil...

Although the (111) surface of Fe3O4 (magnetite) has been investigated for more than twenty years, substantial controversy remains in the literature regarding the surface termination proposed based on structural and adsorption studies. The present paper provides density functional theory results that allow to rationalize experimental results of infrared reflection-absorption spectroscopy and temperature programmed desorption studies on CO adsorption, thus leading to a unified picture in which the Fe3O4(111) surface is terminated by a 1/4 monolayer of tetrahedrally coordinated Fe(3+) ions on top of a close-packed oxygen layer as previously determined by low energy electron diffraction...

Addiction is a serious health problem which leads to general social impairment. The period of adolescence plays a significant role in drug abuse liability. Psychostimulants, such as modafinil (MOD), are majorly used by teenagers seeking improvements in cognition, which contributes to its indiscriminate use. The present study aimed to investigate the influence of MOD (64 mg/kg by gavage, once a day) treatment during adolescence (PND 28-42) on amphetamine (AMPH, 4 mg/kg i.p.) conditioned place preference (CPP) in early adulthood (PND 60)...

Polymers are used in high amounts in a wide range of applications from biomedicine to industry. Because of the growing awareness of the increasing amounts of plastic wastes in the aquatic environment during recent years, the evaluation of their biodegradability deserves special attention. In the past, most efforts were dedicated to studying the biodegradation of polyesters in soil and compost, while very little research has been conducted on their fate in wastewater. Here, we assessed the ability of bacterial communities residing in the aerobic and denitrification tank from a wastewater treatment plant (WWTP) to degrade the polymeric ester polycaprolactone diol (PCLD; average molecular weight of 1250 Da)...
