How Does COVID-19 Risk Perception Affect Sense of Control? The Roles of Death Anxiety and Confucian Coping.

This research examined the impact of COVID-19 risk perception on sense of control, testing the hypotheses that COVID-19 risk perception would reduce sense of control and that this effect would be mediated by death anxiety and moderated by Confucian coping. A series of six studies were conducted with Chinese participants (N = 2202) and employed different research designs in lab and real-life settings. Across the studies, we found that the perceived risk of COVID-19 impaired sense of control. Studies 3a to 5 further revealed that death anxiety mediated the adverse effect of COVID-19 risk perception on sense of control, and Studies 4 to 5 revealed that Confucian coping strategies alleviated the adverse effect of COVID-19 risk perception on sense of control. These findings shed new light on the psychological impact of risk perception in times of crisis and identify mitigating factors and boundary conditions.

E-waste dismantling-related occupational and routine exposure to melamine and its derivatives: Estimating exposure via dust ingestion and hand-to-mouth contact.

Melamine (MEL) and its derivatives are increasingly applied as nitrogenous flame retardants in consumer products. Nevertheless, limited information is available on their environmental occurrence and subsequent human exposure via multiple exposure pathways. In this study, we analysed MEL and its derivatives in dust (indication of the dust ingestion route) and hand wipe samples (indication of the hand-to-mouth route) collected in various microenvironments. The levels of ∑MELs in both dust (median: 24,100 ng/g) and participant hand samples (803 ng/m2) collected in e-waste dismantling workshops were significantly higher than those in samples collected in homes (15,600 ng/g and 196 ng/m2, respectively), dormitories (13,100 ng/g and 227 ng/m2, respectively) and hotel rooms (11,800 ng/g and 154 ng/m2, respectively). Generally, MEL dominated in dust samples collected in e-waste dismantling workshops, whereas cyanuric acid dominated in hand wipe samples. This may occur partly because the latter is an ingredient in disinfection products, which are more frequently employed in daily lives during the COVID-19 pandemic. Exposure assessment suggests that dust ingestion is an important exposure pathway among dismantling workers and the general population, whereas hand-to-mouth contact could not be overlooked in certain populations, such as children and dismantling workers not wear gloves at work.
